CHAPTER TENTH. Former Experiments.--The Doctor's Five Receptacles.--The Gas Cylinder.-- The Calorifere.--The System of Manoeuvring.--Success certain. "The attempt has often been made, gentlemen," said the doctor, "to rise and descend at will, without losing ballast or gas from the balloon. A French aeronaut, M. Meunier, tried to accomplish this by compressing air in an inner receptacle. A Belgian, Dr. Van Hecke, by means of wings and paddles, obtained a vertical power that would have sufficed in most cases, but the practical results secured from these experiments have been insignificant. "I therefore resolved to go about the thing more directly; so, at the start, I dispensed with ballast altogether, excepting as a provision for cases of special emergency, such as the breakage of my apparatus, or the necessity of ascending very suddenly, so as to avoid unforeseen obstacles. "My means of ascent and descent consist simply in dilating or contracting the gas that is in the balloon by the application of different temperatures, and here is the method of obtaining that result. "You saw me bring on board with the car several cases or receptacles, the use of which you may not have understood. They are five in number. "The first contains about twenty-five gallons of water, to which I add a few drops of sulphuric acid, so as to augment its capacity as a conductor of electricity, and then I decompose it by means of a powerful Buntzen battery. Water, as you know, consists of two parts of hydrogen to one of oxygen gas. "The latter, through the action of the battery, passes at its positive pole into the second receptacle. A third receptacle, placed above the second one, and of double its capacity, receives the hydrogen passing into it by the negative pole. "Stopcocks, of which one has an orifice twice the size of the other, communicate between these receptacles and a fourth one, which is called the mixture reservoir, since in it the two gases obtained by the decomposition of the water do really commingle. The capacity of this fourth tank is about forty-one cubic feet. "On the upper part of this tank is a platinum tube provided with a stopcock. "You will now readily understand, gentlemen, the apparatus that I have described to you is really a gas cylinder and blow-pipe for oxygen and hydrogen, the heat of which exceeds that of a forge fire. "This much established, I proceed to the second part of my apparatus. From the lowest part of my balloon, which is hermetically closed, issue two tubes a little distance apart. The one starts among the upper layers of the hydrogen gas, the other amid the lower layers. "These two pipes are provided at intervals with strong jointings of india-rubber, which enable them to move in harmony with the oscillations of the balloon. "Both of them run down as far as the car, and lose themselves in an iron receptacle of cylindrical form, which is called the heat-tank. The latter is closed at its two ends by two strong plates of the same metal. "The pipe running from the lower part of the balloon runs into this cylindrical receptacle through the lower plate; it penetrates the latter and then takes the form of a helicoidal or screw-shaped spiral, the rings of which, rising one over the other, occupy nearly the whole of the height of the tank. Before again issuing from it, this spiral runs into a small cone with a concave base, that is turned downward in the shape of a spherical cap. "It is from the top of this cone that the second pipe issues, and it runs, as I have said, into the upper beds of the balloon. "The spherical cap of the small cone is of platinum, so as not to melt by the action of the cylinder and blow-pipe, for the latter are placed upon the bottom of the iron tank in the midst of the helicoidal spiral, and the extremity of their flame will slightly touch the cap in question. "You all know, gentlemen, what a calorifere, to heat apartments, is. You know how it acts. The air of the apartments is forced to pass through its pipes, and is then released with a heightened temperature. Well, what I have just described to you is nothing more nor less than a calorifere. "In fact, what is it that takes place? The cylinder once lighted, the hydrogen in the spiral and in the concave cone becomes heated, and rapidly ascends through the pipe that leads to the upper part of the balloon. A vacuum is created below, and it attracts the gas in the lower parts; this becomes heated in its turn, and is continually replaced; thus, an extremely rapid current of gas is established in the pipes and in the spiral, which issues from the balloon and then returns to it, and is heated over again, incessantly. "Now, the cases increase 1/480 of their volume for each degree of heat applied. If, then, I force the temperature 18 degrees, the hydrogen of the balloon will dilate 18/480 or 1614 cubic feet, and will, therefore, displace 1614 more cubic feet of air, which will increase its ascensional power by 160 pounds. This is equivalent to throwing out that weight of ballast. If I augment the temperature by 180 degrees, the gas will dilate 180/480 and will displace 16,740 cubic feet more, and its ascensional force will be augmented by 1,600 pounds. "Thus, you see, gentlemen, that I can easily effect very considerable changes of equilibrium. The volume of the balloon has been calculated in such manner that, when half inflated, it displaces a weight of air exactly equal to that of the envelope containing the hydrogen gas, and of the car occupied by the passengers, and all its apparatus and accessories. At this point of inflation, it is in exact equilibrium with the air, and neither mounts nor descends. "In order, then, to effect an ascent, I give the gas a temperature superior to the temperature of the surrounding air by means of my cylinder. By this excess of heat it obtains a larger distention, and inflates the balloon more. The latter, then, ascends in proportion as I heat the hydrogen. "The descent, of course, is effected by lowering the heat of the cylinder, and letting the temperature abate. The ascent would be, usually, more rapid than the descent; but that is a fortunate circumstance, since it is of no importance to me to descend rapidly, while, on the other hand, it is by a very rapid ascent that I avoid obstacles. The real danger lurks below, and not above. "Besides, as I have said, I have a certain quantity of ballast, which will enable me to ascend more rapidly still, when necessary. My valve, at the top of the balloon, is nothing more nor less than a safety-valve. The balloon always retains the same quantity of hydrogen, and the variations of temperature that I produce in the midst of this shut-up gas are, of themselves, sufficient to provide for all these ascending and descending movements. "Now, gentlemen, as a practical detail, let me add this: "The combustion of the hydrogen and of the oxygen at the point of the cylinder produces solely the vapor or steam of water. I have, therefore, provided the lower part of the cylindrical iron box with a scape-pipe, with a valve operating by means of a pressure of two atmospheres; consequently, so soon as this amount of pressure is attained, the steam escapes of itself. "Here are the exact figures: 25 gallons of water, separated into its constituent elements, yield 200 pounds of oxygen and 25 pounds of hydrogen. This represents, at atmospheric tension, 1,800 cubic feet of the former and 3,780 cubic feet of the latter, or 5,670 cubic feet, in all, of the mixture. Hence, the stopcock of my cylinder, when fully open, expends 27 cubic feet per hour, with a flame at least six times as strong as that of the large lamps used for lighting streets. On an average, then, and in order to keep myself at a very moderate elevation, I should not burn more than nine cubic feet per hour, so that my twenty-five gallons of water represent six hundred and thirty-six hours of aerial navigation, or a little more than twenty-six days. "Well, as I can descend when I please, to replenish my stock of water on the way, my trip might be indefinitely prolonged. "Such, gentlemen, is my secret. It is simple, and, like most simple things, it cannot fail to succeed. The dilation and contraction of the gas in the balloon is my means of locomotion, which calls for neither cumbersome wings, nor any other mechanical motor. A calorifere to produce the changes of temperature, and a cylinder to generate the heat, are neither inconvenient nor heavy. I think, therefore, that I have combined all the elements of success." Dr. Ferguson here terminated his discourse, and was most heartily applauded. There was not an objection to make to it; all had been foreseen and decided. "However," said the captain, "the thing may prove dangerous." "What matters that," replied the doctor, "provided that it be practicable?"
CHAPTER ELEVENTH. The Arrival at Zanzibar.--The English Consul.--Ill-will of the Inhabitants.--The Island of Koumbeni.--The Rain-Makers.--Inflation of the Balloon.--Departure on the 18th of April.--The last Good-by. --The Victoria. An invariably favorable wind had accelerated the progress of the Resolute toward the place of her destination. The navigation of the Mozambique Channel was especially calm and pleasant. The agreeable character of the trip by sea was regarded as a good omen of the probable issue of the trip through the air. Every one looked forward to the hour of arrival, and sought to give the last touch to the doctor's preparations. At length the vessel hove in sight of the town of Zanzibar, upon the island of the same name, and, on the 15th of April, at 11 o'clock in the morning, she anchored in the port. The island of Zanzibar belongs to the Imaum of Muscat, an ally of France and England, and is, undoubtedly, his finest settlement. The port is frequented by a great many vessels from the neighboring countries. The island is separated from the African coast only by a channel, the greatest width of which is but thirty miles. It has a large trade in gums, ivory, and, above all, in "ebony," for Zanzibar is the great slave-market. Thither converges all the booty captured in the battles which the chiefs of the interior are continually fighting. This traffic extends along the whole eastern coast, and as far as the Nile latitudes. Mr. G. Lejean even reports that he has seen it carried on, openly, under the French flag. Upon the arrival of the Resolute, the English consul at Zanzibar came on board to offer his services to the doctor, of whose projects the European newspapers had made him aware for a month past. But, up to that moment, he had remained with the numerous phalanx of the incredulous. "I doubted," said he, holding out his hand to Dr. Ferguson, "but now I doubt no longer." He invited the doctor, Kennedy, and the faithful Joe, of course, to his own dwelling. Through his courtesy, the doctor was enabled to have knowledge of the various letters that he had received from Captain Speke. The captain and his companions had suffered dreadfully from hunger and bad weather before reaching the Ugogo country. They could advance only with extreme difficulty, and did not expect to be able to communicate again for a long time. "Those are perils and privations which we shall manage to avoid," said the doctor. The baggage of the three travellers was conveyed to the consul's residence. Arrangements were made for disembarking the balloon upon the beach at Zanzibar. There was a convenient spot, near the signal-mast, close by an immense building, that would serve to shelter it from the east winds. This huge tower, resembling a tun standing on one end, beside which the famous Heidelberg tun would have seemed but a very ordinary barrel, served as a fortification, and on its platform were stationed Belootchees, armed with lances. These Belootchees are a kind of brawling, good-for-nothing Janizaries. But, when about to land the balloon, the consul was informed that the population of the island would oppose their doing so by force. Nothing is so blind as fanatical passion. The news of the arrival of a Christian, who was to ascend into the air, was received with rage. The negroes, more exasperated than the Arabs, saw in this project an attack upon their religion. They took it into their heads that some mischief was meant to the sun and the moon. Now, these two luminaries are objects of veneration to the African tribes, and they determined to oppose so sacrilegious an enterprise. The consul, informed of their intentions, conferred with Dr. Ferguson and Captain Bennet on the subject. The latter was unwilling to yield to threats, but his friend dissuaded him from any idea of violent retaliation. "We shall certainly come out winners," he said. "Even the imaum's soldiers will lend us a hand, if we need it. But, my dear captain, an accident may happen in a moment, and it would require but one unlucky blow to do the balloon an irreparable injury, so that the trip would be totally defeated; therefore we must act with the greatest caution." "But what are we to do? If we land on the coast of Africa, we shall encounter the same difficulties. What are we to do?" "Nothing is more simple," replied the consul. "You observe those small islands outside of the port; land your balloon on one of them; surround it with a guard of sailors, and you will have no risk to run." "Just the thing!" said the doctor, "and we shall be entirely at our ease in completing our preparations." The captain yielded to these suggestions, and the Resolute was headed for the island of Koumbeni. During the morning of the 16th April, the balloon was placed in safety in the middle of a clearing in the great woods, with which the soil is studded. Two masts, eighty feet in height, were raised at the same distance from each other. Blocks and tackle, placed at their extremities, afforded the means of elevating the balloon, by the aid of a transverse rope. It was then entirely uninflated. The interior balloon was fastened to the exterior one, in such manner as to be lifted up in the same way. To the lower end of each balloon were fixed the pipes that served to introduce the hydrogen gas. The whole day, on the 17th, was spent in arranging the apparatus destined to produce the gas; it consisted of some thirty casks, in which the decomposition of water was effected by means of iron-filings and sulphuric acid placed together in a large quantity of the first-named fluid. The hydrogen passed into a huge central cask, after having been washed on the way, and thence into each balloon by the conduit-pipes. In this manner each of them received a certain accurately-ascertained quantity of gas. For this purpose, there had to be employed eighteen hundred and sixty-six pounds of sulphuric acid, sixteen thousand and fifty pounds of iron, and nine thousand one hundred and sixty-six gallons of water. This operation commenced on the following night, about three A.M., and lasted nearly eight hours. The next day, the balloon, covered with its network, undulated gracefully above its car, which was held to the ground by numerous sacks of earth. The inflating apparatus was put together with extreme care, and the pipes issuing from the balloon were securely fitted to the cylindrical case. The anchors, the cordage, the instruments, the travelling-wraps, the awning, the provisions, and the arms, were put in the place assigned to them in the car. The supply of water was procured at Zanzibar. The two hundred pounds of ballast were distributed in fifty bags placed at the bottom of the car, but within arm's-reach. These preparations were concluded about five o'clock in the evening, while sentinels kept close watch around the island, and the boats of the Resolute patrolled the channel. The blacks continued to show their displeasure by grimaces and contortions. Their obi-men, or wizards, went up and down among the angry throngs, pouring fuel on the flame of their fanaticism; and some of the excited wretches, more furious and daring than the rest, attempted to get to the island by swimming, but they were easily driven off. Thereupon the sorceries and incantations commenced; the "rain-makers," who pretend to have control over the clouds, invoked the storms and the "stone-showers," as the blacks call hail, to their aid. To compel them to do so, they plucked leaves of all the different trees that grow in that country, and boiled them over a slow fire, while, at the same time, a sheep was killed by thrusting a long needle into its heart. But, in spite of all their ceremonies, the sky remained clear and beautiful, and they profited nothing by their slaughtered sheep and their ugly grimaces. The blacks then abandoned themselves to the most furious orgies, and got fearfully drunk on "tembo," a kind of ardent spirits drawn from the cocoa-nut tree, and an extremely heady sort of beer called "togwa." Their chants, which were destitute of all melody, but were sung in excellent time, continued until far into the night. About six o'clock in the evening, the captain assembled the travellers and the officers of the ship at a farewell repast in his cabin. Kennedy, whom nobody ventured to question now, sat with his eyes riveted on Dr. Ferguson, murmuring indistinguishable words. In other respects, the dinner was a gloomy one. The approach of the final moment filled everybody with the most serious reflections. What had fate in store for these daring adventurers? Should they ever again find themselves in the midst of their friends, or seated at the domestic hearth? Were their travelling apparatus to fail, what would become of them, among those ferocious savage tribes, in regions that had never been explored, and in the midst of boundless deserts? Such thoughts as these, which had been dim and vague until then, or but slightly regarded when they came up, returned upon their excited fancies with intense force at this parting moment. Dr. Ferguson, still cold and impassible, talked of this, that, and the other; but he strove in vain to overcome this infectious gloominess. He utterly failed. As some demonstration against the personal safety of the doctor and his companions was feared, all three slept that night on board the Resolute. At six o'clock in the morning they left their cabin, and landed on the island of Koumbeni. The balloon was swaying gently to and fro in the morning breeze; the sand-bags that had held it down were now replaced by some twenty strong-armed sailors, and Captain Bennet and his officers were present to witness the solemn departure of their friends. At this moment Kennedy went right up to the doctor, grasped his hand, and said: "Samuel, have you absolutely determined to go?" "Solemnly determined, my dear Dick." "I have done every thing that I could to prevent this expedition, have I not?" "Every thing!" "Well, then, my conscience is clear on that score, and I will go with you." "I was sure you would!" said the doctor, betraying in his features swift traces of emotion. At last the moment of final leave-taking arrived. The captain and his officers embraced their dauntless friends with great feeling, not excepting even Joe, who, worthy fellow, was as proud and happy as a prince. Every one in the party insisted upon having a final shake of the doctor's hand. At nine o'clock the three travellers got into their car. The doctor lit the combustible in his cylinder and turned the flame so as to produce a rapid heat, and the balloon, which had rested on the ground in perfect equipoise, began to rise in a few minutes, so that the seamen had to slacken the ropes they held it by. The car then rose about twenty feet above their heads. "My friends!" exclaimed the doctor, standing up between his two companions, and taking off his hat, "let us give our aerial ship a name that will bring her good luck! let us christen her Victoria!" This speech was answered with stentorian cheers of "Huzza for the Queen! Huzza for Old England!" At this moment the ascensional force of the balloon increased prodigiously, and Ferguson, Kennedy, and Joe, waved a last good-by to their friends. "Let go all!" shouted the doctor, and at the word the Victoria shot rapidly up into the sky, while the four carronades on board the Resolute thundered forth a parting salute in her honor.
CHAPTER TWELFTH Crossing the Strait.--The Mrima.--Dick's Remark and Joe's Proposition.--A Recipe for Coffee-making.--The Uzaramo.--The Unfortunate Maizan.--Mount Dathumi.--The Doctor's Cards.--Night under a Nopal. The air was pure, the wind moderate, and the balloon ascended almost perpendicularly to a height of fifteen hundred feet, as indicated by a depression of two inches in the barometric column. At this height a more decided current carried the balloon toward the southwest. What a magnificent spectacle was then outspread beneath the gaze of the travellers! The island of Zanzibar could be seen in its entire extent, marked out by its deeper color upon a vast planisphere; the fields had the appearance of patterns of different colors, and thick clumps of green indicated the groves and thickets. The inhabitants of the island looked no larger than insects. The huzzaing and shouting were little by little lost in the distance, and only the discharge of the ship's guns could be heard in the concavity beneath the balloon, as the latter sped on its flight. "How fine that is!" said Joe, breaking silence for the first time. He got no reply. The doctor was busy observing the variations of the barometer and noting down the details of his ascent. Kennedy looked on, and had not eyes enough to take in all that he saw. The rays of the sun coming to the aid of the heating cylinder, the tension of the gas increased, and the Victoria attained the height of twenty-five hundred feet. The Resolute looked like a mere cockle-shell, and the African coast could be distinctly seen in the west marked out by a fringe of foam. "You don't talk?" said Joe, again. "We are looking!" said the doctor, directing his spy-glass toward the mainland. "For my part, I must talk!" "As much as you please, Joe; talk as much as you like!" And Joe went on alone with a tremendous volley of exclamations. The "ohs!" and the "ahs!" exploded one after the other, incessantly, from his lips. During his passage over the sea the doctor deemed it best to keep at his present elevation. He could thus reconnoitre a greater stretch of the coast. The thermometer and the barometer, hanging up inside of the half-opened awning, were always within sight, and a second barometer suspended outside was to serve during the night watches. At the end of about two hours the Victoria, driven along at a speed of a little more than eight miles, very visibly neared the coast of the mainland. The doctor, thereupon, determined to descend a little nearer to the ground. So he moderated the flame of his cylinder, and the balloon, in a few moments, had descended to an altitude only three hundred feet above the soil. It was then found to be passing just over the Mrima country, the name of this part of the eastern coast of Africa. Dense borders of mango-trees protected its margin, and the ebb-tide disclosed to view their thick roots, chafed and gnawed by the teeth of the Indian Ocean. The sands which, at an earlier period, formed the coast-line, rounded away along the distant horizon, and Mount Nguru reared aloft its sharp summit in the northwest. The Victoria passed near to a village which the doctor found marked upon his chart as Kaole. Its entire population had assembled in crowds, and were yelling with anger and fear, at the same time vainly directing their arrows against this monster of the air that swept along so majestically away above all their powerless fury. The wind was setting to the southward, but the doctor felt no concern on that score, since it enabled him the better to follow the route traced by Captains Burton and Speke. Kennedy had, at length, become as talkative as Joe, and the two kept up a continual interchange of admiring interjections and exclamations. "Out upon stage-coaches!" said one. "Steamers indeed!" said the other. "Railroads! eh? rubbish!" put in Kennedy, "that you travel on, without seeing the country!" "Balloons! they're the sort for me!" Joe would add. "Why, you don't feel yourself going, and Nature takes the trouble to spread herself out before one's eyes!" "What a splendid sight! What a spectacle! What a delight! a dream in a hammock!" "Suppose we take our breakfast?" was Joe's unpoetical change of tune, at last, for the keen, open air had mightily sharpened his appetite. "Good idea, my boy!" "Oh! it won't take us long to do the cooking--biscuit and potted meat?" "And as much coffee as you like," said the doctor. "I give you leave to borrow a little heat from my cylinder. There's enough and to spare, for that matter, and so we shall avoid the risk of a conflagration." "That would be a dreadful misfortune!" ejaculated Kennedy. "It's the same as a powder-magazine suspended over our heads." "Not precisely," said Ferguson, "but still if the gas were to take fire it would burn up gradually, and we should settle down on the ground, which would be disagreeable; but never fear--our balloon is hermetically sealed." "Let us eat a bite, then," replied Kennedy. "Now, gentlemen," put in Joe, "while doing the same as you, I'm going to get you up a cup of coffee that I think you'll have something to say about." "The fact is," added the doctor, "that Joe, along with a thousand other virtues, has a remarkable talent for the preparation of that delicious beverage: he compounds it of a mixture of various origin, but he never would reveal to me the ingredients." "Well, master, since we are so far above-ground, I can tell you the secret. It is just to mix equal quantities of Mocha, of Bourbon coffee, and of Rio Nunez." A few moments later, three steaming cups of coffee were served, and topped off a substantial breakfast, which was additionally seasoned by the jokes and repartees of the guests. Each one then resumed his post of observation. The country over which they were passing was remarkable for its fertility. Narrow, winding paths plunged in beneath the overarching verdure. They swept along above cultivated fields of tobacco, maize, and barley, at full maturity, and here and there immense rice-fields, full of straight stalks and purple blossoms. They could distinguish sheep and goats too, confined in large cages, set up on piles to keep them out of reach of the leopards' fangs. Luxuriant vegetation spread in wild profuseness over this prodigal soil. Village after village rang with yells of terror and astonishment at the sight of the Victoria, and Dr. Ferguson prudently kept her above the reach of the barbarian arrows. The savages below, thus baffled, ran together from their huddle of huts and followed the travellers with their vain imprecations while they remained in sight. At noon, the doctor, upon consulting his map, calculated that they were passing over the Uzaramo* country. The soil was thickly studded with cocoa-nut, papaw, and cotton-wood trees, above which the balloon seemed to disport itself like a bird. Joe found this splendid vegetation a matter of course, seeing that they were in Africa. Kennedy descried some hares and quails that asked nothing better than to get a good shot from his fowling-piece, but it would have been powder wasted, since there was no time to pick up the game. * U and Ou signify country in the language of that region. The aeronauts swept on with the speed of twelve miles per hour, and soon were passing in thirty-eight degrees twenty minutes east longitude, over the village of Tounda. "It was there," said the doctor, "that Burton and Speke were seized with violent fevers, and for a moment thought their expedition ruined. And yet they were only a short distance from the coast, but fatigue and privation were beginning to tell upon them severely." In fact, there is a perpetual malaria reigning throughout the country in question. Even the doctor could hope to escape its effects only by rising above the range of the miasma that exhales from this damp region whence the blazing rays of the sun pump up its poisonous vapors. Once in a while they could descry a caravan resting in a "kraal," awaiting the freshness and cool of the evening to resume its route. These kraals are wide patches of cleared land, surrounded by hedges and jungles, where traders take shelter against not only the wild beasts, but also the robber tribes of the country. They could see the natives running and scattering in all directions at the sight of the Victoria. Kennedy was keen to get a closer look at them, but the doctor invariably held out against the idea. "The chiefs are armed with muskets," he said, "and our balloon would be too conspicuous a mark for their bullets." "Would a bullet-hole bring us down?" asked Joe. "Not immediately; but such a hole would soon become a large torn orifice through which our gas would escape." "Then, let us keep at a respectful distance from yon miscreants. What must they think as they see us sailing in the air? I'm sure they must feel like worshipping us!" "Let them worship away, then," replied the doctor, "but at a distance. There is no harm done in getting as far away from them as possible. See! the country is already changing its aspect: the villages are fewer and farther between; the mango-trees have disappeared, for their growth ceases at this latitude. The soil is becoming hilly and portends mountains not far off." "Yes," said Kennedy, "it seems to me that I can see some high land on this side." "In the west--those are the nearest ranges of the Ourizara--Mount Duthumi, no doubt, behind which I hope to find shelter for the night. I'll stir up the heat in the cylinder a little, for we must keep at an elevation of five or six hundred feet." "That was a grant idea of yours, sir," said Joe. "It's mighty easy to manage it; you turn a cock, and the thing's done." "Ah! here we are more at our ease," said the sportsman, as the balloon ascended; "the reflection of the sun on those red sands was getting to be insupportable." "What splendid trees!" cried Joe. "They're quite natural, but they are very fine! Why a dozen of them would make a forest!" "Those are baobabs," replied Dr. Ferguson. "See, there's one with a trunk fully one hundred feet in circumference. It was, perhaps, at the foot of that very tree that Maizan, the French traveller, expired in 1845, for we are over the village of Deje-la-Mhora, to which he pushed on alone. He was seized by the chief of this region, fastened to the foot of a baobab, and the ferocious black then severed all his joints while the war-song of his tribe was chanted; he then made a gash in the prisoner's neck, stopped to sharpen his knife, and fairly tore away the poor wretch's head before it had been cut from the body. The unfortunate Frenchman was but twenty-six years of age." "And France has never avenged so hideous a crime?" said Kennedy. "France did demand satisfaction, and the Said of Zanzibar did all in his power to capture the murderer, but in vain." "I move that we don't stop here!" urged Joe; "let us go up, master, let us go up higher by all means." "All the more willingly, Joe, that there is Mount Duthumi right ahead of us. If my calculations be right we shall have passed it before seven o'clock in the evening." "Shall we not travel at night?" asked the Scotchman. "No, as little as possible. With care and vigilance we might do so safely, but it is not enough to sweep across Africa. We want to see it." "Up to this time we have nothing to complain of, master. The best cultivated and most fertile country in the world instead of a desert! Believe the geographers after that!" Let us wait, Joe! we shall see by-and-by." About half-past six in the evening the Victoria was directly opposite Mount Duthumi; in order to pass, it had to ascend to a height of more than three thousand feet, and to accomplish that the doctor had only to raise the temperature of his gas eighteen degrees. It might have been correctly said that he held his balloon in his hand. Kennedy had only to indicate to him the obstacles to be surmounted, and the Victoria sped through the air, skimming the summits of the range. At eight o'clock it descended the farther slope, the acclivity of which was much less abrupt. The anchors were thrown out from the car and one of them, coming in contact with the branches of an enormous nopal, caught on it firmly. Joe at once let himself slide down the rope and secured it. The silk ladder was then lowered to him and he remounted to the car with agility. The balloon now remained perfectly at rest sheltered from the eastern winds. The evening meal was got ready, and the aeronauts, excited by their day's journey, made a heavy onslaught upon the provisions. "What distance have we traversed to-day?" asked Kennedy, disposing of some alarming mouthfuls. The doctor took his bearings, by means of lunar observations, and consulted the excellent map that he had with him for his guidance. It belonged to the Atlas of "Der Neuester Endeckungen in Afrika" ("The Latest Discoveries in Africa"), published at Gotha by his learned friend Dr. Petermann, and by that savant sent to him. This Atlas was to serve the doctor on his whole journey; for it contained the itinerary of Burton and Speke to the great lakes; the Soudan, according to Dr. Barth; the Lower Senegal, according to Guillaume Lejean; and the Delta of the Niger, by Dr. Blaikie. Ferguson had also provided himself with a work which combined in one compilation all the notions already acquired concerning the Nile. It was entitled "The Sources of the Nile; being a General Survey of the Basin of that River and of its Head-Stream, with the History of the Nilotic Discovery, by Charles Beke, D.D." He also had the excellent charts published in the "Bulletins of the Geographical Society of London;" and not a single point of the countries already discovered could, therefore, escape his notice. Upon tracing on his maps, he found that his latitudinal route had been two degrees, or one hundred and twenty miles, to the westward. Kennedy remarked that the route tended toward the south; but this direction was satisfactory to the doctor, who desired to reconnoitre the tracks of his predecessors as much as possible. It was agreed that the night should be divided into three watches, so that each of the party should take his turn in watching over the safety of the rest. The doctor took the watch commencing at nine o'clock; Kennedy, the one commencing at midnight; and Joe, the three o'clock morning watch. So Kennedy and Joe, well wrapped in their blankets, stretched themselves at full length under the awning, and slept quietly; while Dr. Ferguson kept on the lookout.
CHAPTER THIRTEENTH. Change of Weather.--Kennedy has the Fever.--The Doctor's Medicine. --Travels on Land.--The Basin of Imenge.--Mount Rubeho.--Six Thousand Feet Elevation.--A Halt in the Daytime. The night was calm. However, on Saturday morning, Kennedy, as he awoke, complained of lassitude and feverish chills. The weather was changing. The sky, covered with clouds, seemed to be laying in supplies for a fresh deluge. A gloomy region is that Zungomoro country, where it rains continually, excepting, perhaps, for a couple of weeks in the month of January. A violent shower was not long in drenching our travellers. Below them, the roads, intersected by "nullahs," a sort of instantaneous torrent, were soon rendered impracticable, entangled as they were, besides, with thorny thickets and gigantic lianas, or creeping vines. The sulphuretted hydrogen emanations, which Captain Burton mentions, could be distinctly smelt. "According to his statement, and I think he's right," said the doctor, "one could readily believe that there is a corpse hidden behind every thicket." "An ugly country this!" sighed Joe; "and it seems to me that Mr. Kennedy is none the better for having passed the night in it." "To tell the truth, I have quite a high fever," said the sportsman. "There's nothing remarkable about that, my dear Dick, for we are in one of the most unhealthy regions in Africa; but we shall not remain here long; so let's be off." Thanks to a skilful manoeuvre achieved by Joe, the anchor was disengaged, and Joe reascended to the car by means of the ladder. The doctor vigorously dilated the gas, and the Victoria resumed her flight, driven along by a spanking breeze. Only a few scattered huts could be seen through the pestilential mists; but the appearance of the country soon changed, for it often happens in Africa that some of the unhealthiest districts lie close beside others that are perfectly salubrious. Kennedy was visibly suffering, and the fever was mastering his vigorous constitution. "It won't do to fall ill, though," he grumbled; and so saying, he wrapped himself in a blanket, and lay down under the awning. "A little patience, Dick, and you'll soon get over this," said the doctor. "Get over it! Egad, Samuel, if you've any drug in your travelling-chest that will set me on my feet again, bring it without delay. I'll swallow it with my eyes shut!" "Oh, I can do better than that, friend Dick; for I can give you a febrifuge that won't cost any thing." "And how will you do that?" "Very easily. I am simply going to take you up above these clouds that are now deluging us, and remove you from this pestilential atmosphere. I ask for only ten minutes, in order to dilate the hydrogen." The ten minutes had scarcely elapsed ere the travellers were beyond the rainy belt of country. "Wait a little, now, Dick, and you'll begin to feel the effect of pure air and sunshine." "There's a cure for you!" said Joe; "why, it's wonderful!" "No, it's merely natural." "Oh! natural; yes, no doubt of that!" "I bring Dick into good air, as the doctors do, every day, in Europe, or, as I would send a patient at Martinique to the Pitons, a lofty mountain on that island, to get clear of the yellow fever." "Ah! by Jove, this balloon is a paradise!" exclaimed Kennedy, feeling much better already. "It leads to it, anyhow!" replied Joe, quite gravely. It was a curious spectacle--that mass of clouds piled up, at the moment, away below them! The vapors rolled over each other, and mingled together in confused masses of superb brilliance, as they reflected the rays of the sun. The Victoria had attained an altitude of four thousand feet, and the thermometer indicated a certain diminution of temperature. The land below could no longer be seen. Fifty miles away to the westward, Mount Rubeho raised its sparkling crest, marking the limit of the Ugogo country in east longitude thirty-six degrees twenty minutes. The wind was blowing at the rate of twenty miles an hour, but the aeronauts felt nothing of this increased speed. They observed no jar, and had scarcely any sense of motion at all. Three hours later, the doctor's prediction was fully verified. Kennedy no longer felt a single shiver of the fever, but partook of some breakfast with an excellent appetite. That beats sulphate of quinine!" said the energetic Scot, with hearty emphasis and much satisfaction. "Positively," said Joe, "this is where I'll have to retire to when I get old!" About ten o'clock in the morning the atmosphere cleared up, the clouds parted, and the country beneath could again be seen, the Victoria meanwhile rapidly descending. Dr. Ferguson was in search of a current that would carry him more to the northeast, and he found it about six hundred feet from the ground. The country was becoming more broken, and even mountainous. The Zungomoro district was fading out of sight in the east with the last cocoa-nut-trees of that latitude. Ere long, the crests of a mountain-range assumed a more decided prominence. A few peaks rose here and there, and it became necessary to keep a sharp lookout for the pointed cones that seemed to spring up every moment. "We're right among the breakers!" said Kennedy. "Keep cool, Dick. We shan't touch them," was the doctor's quiet answer. "It's a jolly way to travel, anyhow!" said Joe, with his usual flow of spirits. In fact, the doctor managed his balloon with wondrous dexterity. "Now, if we had been compelled to go afoot over that drenched soil," said he, "we should still be dragging along in a pestilential mire. Since our departure from Zanzibar, half our beasts of burden would have died with fatigue. We should be looking like ghosts ourselves, and despair would be seizing on our hearts. We should be in continual squabbles with our guides and porters, and completely exposed to their unbridled brutality. During the daytime, a damp, penetrating, unendurable humidity! At night, a cold frequently intolerable, and the stings of a kind of fly whose bite pierces the thickest cloth, and drives the victim crazy! All this, too, without saying any thing about wild beasts and ferocious native tribes!" "I move that we don't try it!" said Joe, in his droll way. "I exaggerate nothing," continued Ferguson, "for, upon reading the narratives of such travellers as have had the hardihood to venture into these regions, your eyes would fill with tears." About eleven o'clock they were passing over the basin of Imenge, and the tribes scattered over the adjacent hills were impotently menacing the Victoria with their weapons. Finally, she sped along as far as the last undulations of the country which precede Rubeho. These form the last and loftiest chain of the mountains of Usagara. The aeronauts took careful and complete note of the orographic conformation of the country. The three ramifications mentioned, of which the Duthumi forms the first link, are separated by immense longitudinal plains. These elevated summits consist of rounded cones, between which the soil is bestrewn with erratic blocks of stone and gravelly bowlders. The most abrupt declivity of these mountains confronts the Zanzibar coast, but the western slopes are merely inclined planes. The depressions in the soil are covered with a black, rich loam, on which there is a vigorous vegetation. Various water-courses filter through, toward the east, and work their way onward to flow into the Kingani, in the midst of gigantic clumps of sycamore, tamarind, calabash, and palmyra trees. "Attention!" said Dr. Ferguson. "We are approaching Rubeho, the name of which signifies, in the language of the country, the 'Passage of the Winds,' and we would do well to double its jagged pinnacles at a certain height. If my chart be exact, we are going to ascend to an elevation of five thousand feet." "Shall we often have occasion to reach those far upper belts of the atmosphere?" "Very seldom: the height of the African mountains appears to be quite moderate compared with that of the European and Asiatic ranges; but, in any case, our good Victoria will find no difficulty in passing over them." In a very little while, the gas expanded under the action of the heat, and the balloon took a very decided ascensional movement. Besides, the dilation of the hydrogen involved no danger, and only three-fourths of the vast capacity of the balloon was filled when the barometer, by a depression of eight inches, announced an elevation of six thousand feet. "Shall we go this high very long?" asked Joe. "The atmosphere of the earth has a height of six thousand fathoms," said the doctor; "and, with a very large balloon, one might go far. That is what Messrs. Brioschi and Gay-Lussac did; but then the blood burst from their mouths and ears. Respirable air was wanting. Some years ago, two fearless Frenchmen, Messrs. Barral and Bixio, also ventured into the very lofty regions; but their balloon burst--" "And they fell?" asked Kennedy, abruptly. "Certainly they did; but as learned men should always fall--namely, without hurting themselves." "Well, gentlemen," said Joe, "you may try their fall over again, if you like; but, as for me, who am but a dolt, I prefer keeping at the medium height--neither too far up, nor too low down. It won't do to be too ambitious." At the height of six thousand feet, the density of the atmosphere has already greatly diminished; sound is conveyed with difficulty, and the voice is not so easily heard. The view of objects becomes confused; the gaze no longer takes in any but large, quite ill-distinguishable masses; men and animals on the surface become absolutely invisible; the roads and rivers get to look like threads, and the lakes dwindle to ponds. The doctor and his friends felt themselves in a very anomalous condition; an atmospheric current of extreme velocity was bearing them away beyond arid mountains, upon whose summits vast fields of snow surprised the gaze; while their convulsed appearance told of Titanic travail in the earliest epoch of the world's existence. The sun shone at the zenith, and his rays fell perpendicularly upon those lonely summits. The doctor took an accurate design of these mountains, which form four distinct ridges almost in a straight line, the northernmost being the longest. The Victoria soon descended the slope opposite to the Rubeho, skirting an acclivity covered with woods, and dotted with trees of very deep-green foliage. Then came crests and ravines, in a sort of desert which preceded the Ugogo country; and lower down were yellow plains, parched and fissured by the intense heat, and, here and there, bestrewn with saline plants and brambly thickets. Some underbrush, which, farther on, became forests, embellished the horizon. The doctor went nearer to the ground; the anchors were thrown out, and one of them soon caught in the boughs of a huge sycamore. Joe, slipping nimbly down the tree, carefully attached the anchor, and the doctor left his cylinder at work to a certain degree in order to retain sufficient ascensional force in the balloon to keep it in the air. Meanwhile the wind had suddenly died away. "Now," said Ferguson, "take two guns, friend Dick-- one for yourself and one for Joe--and both of you try to bring back some nice cuts of antelope-meat; they will make us a good dinner." "Off to the hunt!" exclaimed Kennedy, joyously. He climbed briskly out of the car and descended. Joe had swung himself down from branch to branch, and was waiting for him below, stretching his limbs in the mean time. "Don't fly away without us, doctor!" shouted Joe. "Never fear, my boy!--I am securely lashed. I'll spend the time getting my notes into shape. A good hunt to you! but be careful. Besides, from my post here, I can observe the face of the country, and, at the least suspicious thing I notice, I'll fire a signal-shot, and with that you must rally home." "Agreed!" said Kennedy; and off they went.
CHAPTER FOURTEENTH. The Forest of Gum-Trees.--The Blue Antelope.--The Rallying-Signal. --An Unexpected Attack.--The Kanyeme.--A Night in the Open Air.--The Mabunguru.--Jihoue-la-Mkoa.--A Supply of Water.--Arrival at Kazeh. The country, dry and parched as it was, consisting of a clayey soil that cracked open with the heat, seemed, indeed, a desert: here and there were a few traces of caravans; the bones of men and animals, that had been half-gnawed away, mouldering together in the same dust. After half an hour's walking, Dick and Joe plunged into a forest of gum-trees, their eyes alert on all sides, and their fingers on the trigger. There was no foreseeing what they might encounter. Without being a rifleman, Joe could handle fire-arms with no trifling dexterity. "A walk does one good, Mr. Kennedy, but this isn't the easiest ground in the world," he said, kicking aside some fragments of quartz with which the soil was bestrewn. Kennedy motioned to his companion to be silent and to halt. The present case compelled them to dispense with hunting-dogs, and, no matter what Joe's agility might be, he could not be expected to have the scent of a setter or a greyhound. A herd of a dozen antelopes were quenching their thirst in the bed of a torrent where some pools of water had lodged. The graceful creatures, snuffing danger in the breeze, seemed to be disturbed and uneasy. Their beautiful heads could be seen between every draught, raised in the air with quick and sudden motion as they sniffed the wind in the direction of our two hunters, with their flexible nostrils. Kennedy stole around behind some clumps of shrubbery, while Joe remained motionless where he was. The former, at length, got within gunshot and fired. The herd disappeared in the twinkling of an eye; one male antelope only, that was hit just behind the shoulder-joint, fell headlong to the ground, and Kennedy leaped toward his booty. It was a blauwbok, a superb animal of a pale-bluish color shading upon the gray, but with the belly and the inside of the legs as white as the driven snow. "A splendid shot!" exclaimed the hunter. "It's a very rare species of the antelope, and I hope to be able to prepare his skin in such a way as to keep it." "Indeed!" said Joe, "do you think of doing that, Mr. Kennedy?" "Why, certainly I do! Just see what a fine hide it is!" "But Dr. Ferguson will never allow us to take such an extra weight!" "You're right, Joe. Still it is a pity to have to leave such a noble animal." "The whole of it? Oh, we won't do that, sir; we'll take all the good eatable parts of it, and, if you'll let me, I'll cut him up just as well as the chairman of the honorable corporation of butchers of the city of London could do." "As you please, my boy! But you know that in my hunter's way I can just as easily skin and cut up a piece of game as kill it." "I'm sure of that, Mr. Kennedy. Well, then, you can build a fireplace with a few stones; there's plenty of dry dead-wood, and I can make the hot coals tell in a few minutes." "Oh! that won't take long," said Kennedy, going to work on the fireplace, where he had a brisk flame crackling and sparkling in a minute or two. Joe had cut some of the nicest steaks and the best parts of the tenderloin from the carcass of the antelope, and these were quickly transformed to the most savory of broils. "There, those will tickle the doctor!" said Kennedy. "Do you know what I was thinking about?" said Joe. "Why, about the steaks you're broiling, to be sure!" replied Dick. "Not the least in the world. I was thinking what a figure we'd cut if we couldn't find the balloon again." "By George, what an idea! Why, do you think the doctor would desert us?" "No; but suppose his anchor were to slip!" "Impossible! and, besides, the doctor would find no difficulty in coming down again with his balloon; he handles it at his ease." "But suppose the wind were to sweep it off, so that he couldn't come back toward us?" "Come, come, Joe! a truce to your suppositions; they're any thing but pleasant." "Ah! sir, every thing that happens in this world is natural, of course; but, then, any thing may happen, and we ought to look out beforehand." At this moment the report of a gun rang out upon the air. "What's that?" exclaimed Joe. "It's my rifle, I know the ring of her!" said Kennedy. "A signal!" "Yes; danger for us!" "For him, too, perhaps." "Let's be off!" And the hunters, having gathered up the product of their expedition, rapidly made their way back along the path that they had marked by breaking boughs and bushes when they came. The density of the underbrush prevented their seeing the balloon, although they could not be far from it. A second shot was heard. "We must hurry!" said Joe. "There! a third report!" "Why, it sounds to me as if he was defending himself against something." "Let us make haste!" They now began to run at the top of their speed. When they reached the outskirts of the forest, they, at first glance, saw the balloon in its place and the doctor in the car. "What's the matter?" shouted Kennedy. "Good God!" suddenly exclaimed Joe. "What do you see?" "Down there! look! a crowd of blacks surrounding the balloon!" And, in fact, there, two miles from where they were, they saw some thirty wild natives close together, yelling, gesticulating, and cutting all kinds of antics at the foot of the sycamore. Some, climbing into the tree itself, were making their way to the topmost branches. The danger seemed pressing. "My master is lost!" cried Joe. "Come! a little more coolness, Joe, and let us see how we stand. We hold the lives of four of those villains in our hands. Forward, then!" They had made a mile with headlong speed, when another report was heard from the car. The shot had, evidently, told upon a huge black demon, who had been hoisting himself up by the anchor-rope. A lifeless body fell from bough to bough, and hung about twenty feet from the ground, its arms and legs swaying to and fro in the air. "Ha!" said Joe, halting, "what does that fellow hold by?" "No matter what!" said Kennedy; "let us run! let us run!" "Ah! Mr. Kennedy," said Joe, again, in a roar of laughter, "by his tail! by his tail! it's an ape! They're all apes!" "Well, they're worse than men!" said Kennedy, as he dashed into the midst of the howling crowd. It was, indeed, a troop of very formidable baboons of the dog-faced species. These creatures are brutal, ferocious, and horrible to look upon, with their dog-like muzzles and savage expression. However, a few shots scattered them, and the chattering horde scampered off, leaving several of their number on the ground. In a moment Kennedy was on the ladder, and Joe, clambering up the branches, detached the anchor; the car then dipped to where he was, and he got into it without difficulty. A few minutes later, the Victoria slowly ascended and soared away to the eastward, wafted by a moderate wind. "That was an attack for you!" said Joe. "We thought you were surrounded by natives." "Well, fortunately, they were only apes," said the doctor. "At a distance there's no great difference," remarked Kennedy. "Nor close at hand, either," added Joe. "Well, however that may be," resumed Ferguson, "this attack of apes might have had the most serious consequences. Had the anchor yielded to their repeated efforts, who knows whither the wind would have carried me?" "What did I tell you, Mr. Kennedy?" "You were right, Joe; but, even right as you may have been, you were, at that moment, preparing some antelope-steaks, the very sight of which gave me a monstrous appetite." "I believe you!" said the doctor; "the flesh of the antelope is exquisite." "You may judge of that yourself, now, sir, for supper's ready." "Upon my word as a sportsman, those venison-steaks have a gamy flavor that's not to be sneezed at, I tell you." "Good!" said Joe, with his mouth full, "I could live on antelope all the days of my life; and all the better with a glass of grog to wash it down." So saying, the good fellow went to work to prepare a jorum of that fragrant beverage, and all hands tasted it with satisfaction. "Every thing has gone well thus far," said he. "Very well indeed!" assented Kennedy. "Come, now, Mr. Kennedy, are you sorry that you came with us?" "I'd like to see anybody prevent my coming!" It was now four o'clock in the afternoon. The Victoria had struck a more rapid current. The face of the country was gradually rising, and, ere long, the barometer indicated a height of fifteen hundred feet above the level of the sea. The doctor was, therefore, obliged to keep his balloon up by a quite considerable dilation of gas, and the cylinder was hard at work all the time. Toward seven o'clock, the balloon was sailing over the basin of Kanyeme. The doctor immediately recognized that immense clearing, ten miles in extent, with its villages buried in the midst of baobab and calabash trees. It is the residence of one of the sultans of the Ugogo country, where civilization is, perhaps, the least backward. The natives there are less addicted to selling members of their own families, but still, men and animals all live together in round huts, without frames, that look like haystacks. Beyond Kanyeme the soil becomes arid and stony, but in an hour's journey, in a fertile dip of the soil, vegetation had resumed all its vigor at some distance from Mdaburu. The wind fell with the close of the day, and the atmosphere seemed to sleep. The doctor vainly sought for a current of air at different heights, and, at last, seeing this calm of all nature, he resolved to pass the night afloat, and, for greater safety, rose to the height of one thousand feet, where the balloon remained motionless. The night was magnificent, the heavens glittering with stars, and profoundly silent in the upper air. Dick and Joe stretched themselves on their peaceful couch, and were soon sound asleep, the doctor keeping the first watch. At twelve o'clock the latter was relieved by Kennedy. "Should the slightest accident happen, waken me," said Ferguson, "and, above all things, don't lose sight of the barometer. To us it is the compass!" The night was cold. There were twenty-seven degrees of difference between its temperature and that of the daytime. With nightfall had begun the nocturnal concert of animals driven from their hiding-places by hunger and thirst. The frogs struck in their guttural soprano, redoubled by the yelping of the jackals, while the imposing bass of the African lion sustained the accords of this living orchestra. Upon resuming his post, in the morning, the doctor consulted his compass, and found that the wind had changed during the night. The balloon had been bearing about thirty miles to the northwest during the last two hours. It was then passing over Mabunguru, a stony country, strewn with blocks of syenite of a fine polish, and knobbed with huge bowlders and angular ridges of rock; conic masses, like the rocks of Karnak, studded the soil like so many Druidic dolmens; the bones of buffaloes and elephants whitened it here and there; but few trees could be seen, excepting in the east, where there were dense woods, among which a few villages lay half concealed. Toward seven o'clock they saw a huge round rock nearly two miles in extent, like an immense tortoise. "We are on the right track," said Dr. Ferguson. "There's Jihoue-la-Mkoa, where we must halt for a few minutes. I am going to renew the supply of water necessary for my cylinder, and so let us try to anchor somewhere." "There are very few trees," replied the hunger. "Never mind, let us try. Joe, throw out the anchors!" The balloon, gradually losing its ascensional force, approached the ground; the anchors ran along until, at last, one of them caught in the fissure of a rock, and the balloon remained motionless. It must not be supposed that the doctor could entirely extinguish his cylinder, during these halts. The equilibrium of the balloon had been calculated at the level of the sea; and, as the country was continually ascending, and had reached an elevation of from six to seven hundred feet, the balloon would have had a tendency to go lower than the surface of the soil itself. It was, therefore, necessary to sustain it by a certain dilation of the gas. But, in case the doctor, in the absence of all wind, had let the car rest upon the ground, the balloon, thus relieved of a considerable weight, would have kept up of itself, without the aid of the cylinder. The maps indicated extensive ponds on the western slope of the Jihoue-la-Mkoa. Joe went thither alone with a cask that would hold about ten gallons. He found the place pointed out to him, without difficulty, near to a deserted village; got his stock of water, and returned in less than three-quarters of an hour. He had seen nothing particular excepting some immense elephant-pits. In fact, he came very near falling into one of them, at the bottom of which lay a half-eaten carcass. He brought back with him a sort of clover which the apes eat with avidity. The doctor recognized the fruit of the "mbenbu"-tree which grows in profusion, on the western part of Jihoue-la-Mkoa. Ferguson waited for Joe with a certain feeling of impatience, for even a short halt in this inhospitable region always inspires a degree of fear. The water was got aboard without trouble, as the car was nearly resting on the ground. Joe then found it easy to loosen the anchor and leaped lightly to his place beside the doctor. The latter then replenished the flame in the cylinder, and the balloon majestically soared into the air. It was then about one hundred miles from Kazeh, an important establishment in the interior of Africa, where, thanks to a south-southeasterly current, the travellers might hope to arrive on that same day. They were moving at the rate of fourteen miles per hour, and the guidance of the balloon was becoming difficult, as they dared not rise very high without extreme dilation of the gas, the country itself being at an average height of three thousand feet. Hence, the doctor preferred not to force the dilation, and so adroitly followed the sinuosities of a pretty sharply-inclined plane, and swept very close to the villages of Thembo and Tura-Wels. The latter forms part of the Unyamwezy, a magnificent country, where the trees attain enormous dimensions; among them the cactus, which grows to gigantic size. About two o'clock, in magnificent weather, but under a fiery sun that devoured the least breath of air, the balloon was floating over the town of Kazeh, situated about three hundred and fifty miles from the coast. "We left Zanzibar at nine o'clock in the morning," said the doctor, consulting his notes, "and, after two days' passage, we have, including our deviations, travelled nearly five hundred geographical miles. Captains Burton and Speke took four months and a half to make the same distance!"
CHAPTER FIFTEENTH. Kazeh.--The Noisy Market-place.--The Appearance of the Balloon.--The Wangaga.--The Sons of the Moon.--The Doctor's Walk.--The Population of the Place.--The Royal Tembe.--The Sultan's Wives.--A Royal Drunken-Bout.-- Joe an Object of Worship.--How they Dance in the Moon.--A Reaction.-- Two Moons in one Sky.--The Instability of Divine Honors. Kazeh, an important point in Central Africa, is not a city; in truth, there are no cities in the interior. Kazeh is but a collection of six extensive excavations. There are enclosed a few houses and slave-huts, with little courtyards and small gardens, carefully cultivated with onions, potatoes, cucumbers, pumpkins, and mushrooms, of perfect flavor, growing most luxuriantly. The Unyamwezy is the country of the Moon--above all the rest, the fertile and magnificent garden-spot of Africa. In its centre is the district of Unyanembe--a delicious region, where some families of Omani, who are of very pure Arabic origin, live in luxurious idleness. They have, for a long period, held the commerce between the interior of Africa and Arabia: they trade in gums, ivory, fine muslin, and slaves. Their caravans traverse these equatorial regions on all sides; and they even make their way to the coast in search of those articles of luxury and enjoyment which the wealthy merchants covet; while the latter, surrounded by their wives and their attendants, lead in this charming country the least disturbed and most horizontal of lives--always stretched at full length, laughing, smoking, or sleeping. Around these excavations are numerous native dwellings; wide, open spaces for the markets; fields of cannabis and datura; superb trees and depths of freshest shade--such is Kazeh! There, too, is held the general rendezvous of the caravans --those of the south, with their slaves and their freightage of ivory; and those of the west, which export cotton, glassware, and trinkets, to the tribes of the great lakes. So in the market-place there reigns perpetual excitement, a nameless hubbub, made up of the cries of mixed-breed porters and carriers, the beating of drums, and the twanging of horns, the neighing of mules, the braying of donkeys, the singing of women, the squalling of children, and the banging of the huge rattan, wielded by the jemadar or leader of the caravans, who beats time to this pastoral symphony. There, spread forth, without regard to order--indeed, we may say, in charming disorder--are the showy stuffs, the glass beads, the ivory tusks, the rhinoceros'-teeth, the shark's-teeth, the honey, the tobacco, and the cotton of these regions, to be purchased at the strangest of bargains by customers in whose eyes each article has a price only in proportion to the desire it excites to possess it. All at once this agitation, movement and noise stopped as though by magic. The balloon had just come in sight, far aloft in the sky, where it hovered majestically for a few moments, and then descended slowly, without deviating from its perpendicular. Men, women, children, merchants and slaves, Arabs and negroes, as suddenly disappeared within the "tembes" and the huts. "My dear doctor," said Kennedy, "if we continue to produce such a sensation as this, we shall find some difficulty in establishing commercial relations with the people hereabouts." "There's one kind of trade that we might carry on, though, easily enough," said Joe; "and that would be to go down there quietly, and walk off with the best of the goods, without troubling our heads about the merchants; we'd get rich that way!" "Ah!" said the doctor, "these natives are a little scared at first; but they won't be long in coming back, either through suspicion or through curiosity." "Do you really think so, doctor?" "Well, we'll see pretty soon. But it wouldn't be prudent to go too near to them, for the balloon is not iron-clad, and is, therefore, not proof against either an arrow or a bullet." "Then you expect to hold a parley with these blacks?" "If we can do so safely, why should we not? There must be some Arab merchants here at Kazeh, who are better informed than the rest, and not so barbarous. I remember that Burton and Speke had nothing but praises to utter concerning the hospitality of these people; so we might, at least, make the venture." The balloon having, meanwhile, gradually approached the ground, one of the anchors lodged in the top of a tree near the market-place. By this time the whole population had emerged from their hiding-places stealthily, thrusting their heads out first. Several "waganga," recognizable by their badges of conical shellwork, came boldly forward. They were the sorcerers of the place. They bore in their girdles small gourds, coated with tallow, and several other articles of witchcraft, all of them, by-the-way, most professionally filthy. Little by little the crowd gathered beside them, the women and children grouped around them, the drums renewed their deafening uproar, hands were violently clapped together, and then raised toward the sky. "That's their style of praying," said the doctor; "and, if I'm not mistaken, we're going to be called upon to play a great part." "Well, sir, play it!" "You, too, my good Joe--perhaps you're to be a god!" "Well, master, that won't trouble me much. I like a little flattery!" At this moment, one of the sorcerers, a "myanga," made a sign, and all the clamor died away into the profoundest silence. He then addressed a few words to the strangers, but in an unknown tongue. Dr. Ferguson, not having understood them, shouted some sentences in Arabic, at a venture, and was immediately answered in that language. The speaker below then delivered himself of a very copious harangue, which was also very flowery and very gravely listened to by his audience. From it the doctor was not slow in learning that the balloon was mistaken for nothing less than the moon in person, and that the amiable goddess in question had condescended to approach the town with her three sons--an honor that would never be forgotten in this land so greatly loved by the god of day. The doctor responded, with much dignity, that the moon made her provincial tour every thousand years, feeling the necessity of showing herself nearer at hand to her worshippers. He, therefore, begged them not to be disturbed by her presence, but to take advantage of it to make known all their wants and longings. The sorcerer, in his turn, replied that the sultan, the "mwani," who had been sick for many years, implored the aid of heaven, and he invited the son of the moon to visit him. The doctor acquainted his companions with the invitation. "And you are going to call upon this negro king?" asked Kennedy. "Undoubtedly so; these people appear well disposed; the air is calm; there is not a breath of wind, and we have nothing to fear for the balloon?" "But, what will you do?" "Be quiet on that score, my dear Dick. With a little medicine, I shall work my way through the affair!" Then, addressing the crowd, he said: "The moon, taking compassion on the sovereign who is so dear to the children of Unyamwezy, has charged us to restore him to health. Let him prepare to receive us!" The clamor, the songs and demonstrations of all kinds increased twofold, and the whole immense ants' nest of black heads was again in motion. "Now, my friends," said Dr. Ferguson, "we must look out for every thing beforehand; we may be forced to leave this at any moment, unexpectedly, and be off with extra speed. Dick had better remain, therefore, in the car, and keep the cylinder warm so as to secure a sufficient ascensional force for the balloon. The anchor is solidly fastened, and there is nothing to fear in that respect. I shall descend, and Joe will go with me, only that he must remain at the foot of the ladder." "What! are you going alone into that blackamoor's den?" "How! doctor, am I not to go with you?" "No! I shall go alone; these good folks imagine that the goddess of the moon has come to see them, and their superstition protects me; so have no fear, and each one remain at the post that I have assigned to him." "Well, since you wish it," sighed Kennedy. "Look closely to the dilation of the gas." "Agreed!" By this time the shouts of the natives had swelled to double volume as they vehemently implored the aid of the heavenly powers. "There, there," said Joe, "they're rather rough in their orders to their good moon and her divine sons." The doctor, equipped with his travelling medicine-chest, descended to the ground, preceded by Joe, who kept a straight countenance and looked as grave and knowing as the circumstances of the case required. He then seated himself at the foot of the ladder in the Arab fashion, with his legs crossed under him, and a portion of the crowd collected around him in a circle, at respectful distances. In the meanwhile the doctor, escorted to the sound of savage instruments, and with wild religious dances, slowly proceeded toward the royal "tembe," situated a considerable distance outside of the town. It was about three o'clock, and the sun was shining brilliantly. In fact, what less could it do upon so grand an occasion! The doctor stepped along with great dignity, the waganga surrounding him and keeping off the crowd. He was soon joined by the natural son of the sultan, a handsomely-built young fellow, who, according to the custom of the country, was the sole heir of the paternal goods, to the exclusion of the old man's legitimate children. He prostrated himself before the son of the moon, but the latter graciously raised him to his feet. Three-quarters of an hour later, through shady paths, surrounded by all the luxuriance of tropical vegetation, this enthusiastic procession arrived at the sultan's palace, a sort of square edifice called ititenya, and situated on the slope of a hill. A kind of veranda, formed by the thatched roof, adorned the outside, supported upon wooden pillars, which had some pretensions to being carved. Long lines of dark-red clay decorated the walls in characters that strove to reproduce the forms of men and serpents, the latter better imitated, of course, than the former. The roofing of this abode did not rest directly upon the walls, and the air could, therefore, circulate freely, but windows there were none, and the door hardly deserved the name. Dr. Ferguson was received with all the honors by the guards and favorites of the sultan; these were men of a fine race, the Wanyamwezi so-called, a pure type of the central African populations, strong, robust, well-made, and in splendid condition. Their hair, divided into a great number of small tresses, fell over their shoulders, and by means of black-and-blue incisions they had tattooed their cheeks from the temples to the mouth. Their ears, frightfully distended, held dangling to them disks of wood and plates of gum copal. They were clad in brilliantly-painted cloths, and the soldiers were armed with the saw-toothed war-club, the bow and arrows barbed and poisoned with the juice of the euphorbium, the cutlass, the "sima," a long sabre (also with saw-like teeth), and some small battle-axes. The doctor advanced into the palace, and there, notwithstanding the sultan's illness, the din, which was terrific before, redoubled the instant that he arrived. He noticed, at the lintels of the door, some rabbits' tails and zebras' manes, suspended as talismans. He was received by the whole troop of his majesty's wives, to the harmonious accords of the "upatu," a sort of cymbal made of the bottom of a copper kettle, and to the uproar of the "kilindo," a drum five feet high, hollowed out from the trunk of a tree, and hammered by the ponderous, horny fists of two jet-black virtuosi. Most of the women were rather good-looking, and they laughed and chattered merrily as they smoked their tobacco and "thang" in huge black pipes. They seemed to be well made, too, under the long robes that they wore gracefully flung about their persons, and carried a sort of "kilt" woven from the fibres of calabash fastened around their girdles. Six of them were not the least merry of the party, although put aside from the rest, and reserved for a cruel fate. On the death of the sultan, they were to be buried alive with him, so as to occupy and divert his mind during the period of eternal solitude. Dr. Ferguson, taking in the whole scene at a rapid glance, approached the wooden couch on which the sultan lay reclining. There he saw a man of about forty, completely brutalized by orgies of every description, and in a condition that left little or nothing to be done. The sickness that had afflicted him for so many years was simply perpetual drunkenness. The royal sot had nearly lost all consciousness, and all the ammonia in the world would not have set him on his feet again. His favorites and the women kept on bended knees during this solemn visit. By means of a few drops of powerful cordial, the doctor for a moment reanimated the imbruted carcass that lay before him. The sultan stirred, and, for a dead body that had given no sign whatever of life for several hours previously, this symptom was received with a tremendous repetition of shouts and cries in the doctor's honor. The latter, who had seen enough of it by this time, by a rapid motion put aside his too demonstrative admirers and went out of the palace, directing his steps immediately toward the balloon, for it was now six o'clock in the evening. Joe, during his absence, had been quietly waiting at the foot of the ladder, where the crowd paid him their most humble respects. Like a genuine son of the moon, he let them keep on. For a divinity, he had the air of a very clever sort of fellow, by no means proud, nay, even pleasingly familiar with the young negresses, who seemed never to tire of looking at him. Besides, he went so far as to chat agreeably with them. "Worship me, ladies! worship me!" he said to them. "I'm a clever sort of devil, if I am the son of a goddess." They brought him propitiatory gifts, such as are usually deposited in the fetich huts or mzimu. These gifts consisted of stalks of barley and of "pombe." Joe considered himself in duty bound to taste the latter species of strong beer, but his palate, although accustomed to gin and whiskey, could not withstand the strength of the new beverage, and he had to make a horrible grimace, which his dusky friends took to be a benevolent smile. Thereupon, the young damsels, conjoining their voices in a drawling chant, began to dance around him with the utmost gravity. "Ah! you're dancing, are you?" said he. "Well, I won't be behind you in politeness, and so I'll give you one of my country reels." So at it he went, in one of the wildest jigs that ever was seen, twisting, turning, and jerking himself in all directions; dancing with his hands, dancing with his body, dancing with his knees, dancing with his feet; describing the most fearful contortions and extravagant evolutions; throwing himself into incredible attitudes; grimacing beyond all belief, and, in fine giving his savage admirers a strange idea of the style of ballet adopted by the deities in the moon. Then, the whole collection of blacks, naturally as imitative as monkeys, at once reproduced all his airs and graces, his leaps and shakes and contortions; they did not lose a single gesticulation; they did not forget an attitude; and the result was, such a pandemonium of movement, noise, and excitement, as it would be out of the question even feebly to describe. But, in the very midst of the fun, Joe saw the doctor approaching. The latter was coming at full speed, surrounded by a yelling and disorderly throng. The chiefs and sorcerers seemed to be highly excited. They were close upon the doctor's heels, crowding and threatening him. Singular reaction! What had happened? Had the sultan unluckily perished in the hands of his celestial physician? Kennedy, from his post of observation, saw the danger without knowing what had caused it, and the balloon, powerfully urged by the dilation of the gas, strained and tugged at the ropes that held it as though impatient to soar away. The doctor had got as far as the foot of the ladder. A superstitious fear still held the crowd aloof and hindered them from committing any violence on his person. He rapidly scaled the ladder, and Joe followed him with his usual agility. "Not a moment to lose!" said the doctor. "Don't attempt to let go the anchor! We'll cut the cord! Follow me!" "But what's the matter?" asked Joe, clambering into the car. "What's happened?" questioned Kennedy, rifle in hand. "Look!" replied the doctor, pointing to the horizon. "Well?" ejaculated the Scot. "Well! the moon!" And, in fact, there was the moon rising red and magnificent, a globe of fire in a field of blue! It was she, indeed--she and the balloon!--both in one sky! Either there were two moons, then, or these strangers were imposters, designing scamps, false deities! Such were the very natural reflections of the crowd, and hence the reaction in their feelings. Joe could not, for the life of him, keep in a roar of laughter; and the population of Kazeh, comprehending that their prey was slipping through their clutches, set up prolonged howlings, aiming, the while, their bows and muskets at the balloon. But one of the sorcerers made a sign, and all the weapons were lowered. He then began to climb into the tree, intending to seize the rope and bring the machine to the ground. Joe leaned out with a hatchet ready. "Shall I cut away?" said he. "No; wait a moment," replied the doctor. "But this black?" "We may, perhaps, save our anchor--and I hold a great deal by that. There'll always be time enough to cut loose." The sorcerer, having climbed to the right place, worked so vigorously that he succeeded in detaching the anchor, and the latter, violently jerked, at that moment, by the start of the balloon, caught the rascal between the limbs, and carried him off astride of it through the air. The stupefaction of the crowd was indescribable as they saw one of their waganga thus whirled away into space. "Huzza!" roared Joe, as the balloon--thanks to its ascensional force--shot up higher into the sky, with increased rapidity. "He holds on well," said Kennedy; "a little trip will do him good." "Shall we let this darky drop all at once?" inquired Joe. "Oh no," replied the doctor, "we'll let him down easily; and I warrant me that, after such an adventure, the power of the wizard will be enormously enhanced in the sight of his comrades." "Why, I wouldn't put it past them to make a god of him!" said Joe, with a laugh. The Victoria, by this time, had risen to the height of one thousand feet, and the black hung to the rope with desperate energy. He had become completely silent, and his eyes were fixed, for his terror was blended with amazement. A light west wind was sweeping the balloon right over the town, and far beyond it. Half an hour later, the doctor, seeing the country deserted, moderated the flame of his cylinder, and descended toward the ground. At twenty feet above the turf, the affrighted sorcerer made up his mind in a twinkling: he let himself drop, fell on his feet, and scampered off at a furious pace toward Kazeh; while the balloon, suddenly relieved of his weight, again shot up on her course.
CHAPTER SIXTEENTH. Symptoms of a Storm.--The Country of the Moon.--The Future of the African Continent.--The Last Machine of all.--A View of the Country at Sunset.-- Flora and Fauna.--The Tempest.--The Zone of Fire.--The Starry Heavens. "See," said Joe, "what comes of playing the sons of the moon without her leave! She came near serving us an ugly trick. But say, master, did you damage your credit as a physician?" "Yes, indeed," chimed in the sportsman. "What kind of a dignitary was this Sultan of Kazeh?" "An old half-dead sot," replied the doctor, "whose loss will not be very severely felt. But the moral of all this is that honors are fleeting, and we must not take too great a fancy to them." "So much the worse!" rejoined Joe. "I liked the thing--to be worshipped!--Play the god as you like! Why, what would any one ask more than that? By-the-way, the moon did come up, too, and all red, as if she was in a rage." While the three friends went on chatting of this and other things, and Joe examined the luminary of night from an entirely novel point of view, the heavens became covered with heavy clouds to the northward, and the lowering masses assumed a most sinister and threatening look. Quite a smart breeze, found about three hundred feet from the earth, drove the balloon toward the north-northeast; and above it the blue vault was clear; but the atmosphere felt close and dull. The aeronauts found themselves, at about eight in the evening, in thirty-two degrees forty minutes east longitude, and four degrees seventeen minutes latitude. The atmospheric currents, under the influence of a tempest not far off, were driving them at the rate of from thirty to thirty-five miles an hour; the undulating and fertile plains of Mfuto were passing swiftly beneath them. The spectacle was one worthy of admiration--and admire it they did. "We are now right in the country of the Moon," said Dr. Ferguson; "for it has retained the name that antiquity gave it, undoubtedly, because the moon has been worshipped there in all ages. It is, really, a superb country." "It would be hard to find more splendid vegetation." "If we found the like of it around London it would not be natural, but it would be very pleasant," put in Joe. "Why is it that such savage countries get all these fine things?" "And who knows," said the doctor, "that this country may not, one day, become the centre of civilization? The races of the future may repair hither, when Europe shall have become exhausted in the effort to feed her inhabitants." "Do you think so, really?" asked Kennedy. "Undoubtedly, my dear Dick. Just note the progress of events: consider the migrations of races, and you will arrive at the same conclusion assuredly. Asia was the first nurse of the world, was she not? For about four thousand years she travailed, she grew pregnant, she produced, and then, when stones began to cover the soil where the golden harvests sung by Homer had flourished, her children abandoned her exhausted and barren bosom. You next see them precipitating themselves upon young and vigorous Europe, which has nourished them for the last two thousand years. But already her fertility is beginning to die out; her productive powers are diminishing every day. Those new diseases that annually attack the products of the soil, those defective crops, those insufficient resources, are all signs of a vitality that is rapidly wearing out and of an approaching exhaustion. Thus, we already see the millions rushing to the luxuriant bosom of America, as a source of help, not inexhaustible indeed, but not yet exhausted. In its turn, that new continent will grow old; its virgin forests will fall before the axe of industry, and its soil will become weak through having too fully produced what had been demanded of it. Where two harvests bloomed every year, hardly one will be gathered from a soil completely drained of its strength. Then, Africa will be there to offer to new races the treasures that for centuries have been accumulating in her breast. Those climates now so fatal to strangers will be purified by cultivation and by drainage of the soil, and those scattered water supplies will be gathered into one common bed to form an artery of navigation. Then this country over which we are now passing, more fertile, richer, and fuller of vitality than the rest, will become some grand realm where more astonishing discoveries than steam and electricity will be brought to light." "Ah! sir," said Joe, "I'd like to see all that." "You got up too early in the morning, my boy!" "Besides," said Kennedy, "that may prove to be a very dull period when industry will swallow up every thing for its own profit. By dint of inventing machinery, men will end in being eaten up by it! I have always fancied that the end of the earth will be when some enormous boiler, heated to three thousand millions of atmospheric pressure, shall explode and blow up our Globe!" "And I add that the Americans," said Joe, "will not have been the last to work at the machine!" "In fact," assented the doctor, "they are great boiler-makers! But, without allowing ourselves to be carried away by such speculations, let us rest content with enjoying the beauties of this country of the Moon, since we have been permitted to see it." The sun, darting his last rays beneath the masses of heaped-up cloud, adorned with a crest of gold the slightest inequalities of the ground below; gigantic trees, arborescent bushes, mosses on the even surface--all had their share of this luminous effulgence. The soil, slightly undulating, here and there rose into little conical hills; there were no mountains visible on the horizon; immense brambly palisades, impenetrable hedges of thorny jungle, separated the clearings dotted with numerous villages, and immense euphorbiae surrounded them with natural fortifications, interlacing their trunks with the coral-shaped branches of the shrubbery and undergrowth. Ere long, the Malagazeri, the chief tributary of Lake Tanganayika, was seen winding between heavy thickets of verdure, offering an asylum to many water-courses that spring from the torrents formed in the season of freshets, or from ponds hollowed in the clayey soil. To observers looking from a height, it was a chain of waterfalls thrown across the whole western face of the country. Animals with huge humps were feeding in the luxuriant prairies, and were half hidden, sometimes, in the tall grass; spreading forests in bloom redolent of spicy perfumes presented themselves to the gaze like immense bouquets; but, in these bouquets, lions, leopards, hyenas, and tigers, were then crouching for shelter from the last hot rays of the setting sun. From time to time, an elephant made the tall tops of the undergrowth sway to and fro, and you could hear the crackling of huge branches as his ponderous ivory tusks broke them in his way. "What a sporting country!" exclaimed Dick, unable longer to restrain his enthusiasm; "why, a single ball fired at random into those forests would bring down game worthy of it. Suppose we try it once!" "No, my dear Dick; the night is close at hand--a threatening night with a tempest in the background--and the storms are awful in this country, where the heated soil is like one vast electric battery." "You are right, sir," said Joe, "the heat has got to be enough to choke one, and the breeze has died away. One can feel that something's coming." "The atmosphere is saturated with electricity," replied the doctor; "every living creature is sensible that this state of the air portends a struggle of the elements, and I confess that I never before was so full of the fluid myself." "Well, then," suggested Dick, "would it not be advisable to alight?" "On the contrary, Dick, I'd rather go up, only that I am afraid of being carried out of my course by these counter-currents contending in the atmosphere." "Have you any idea, then, of abandoning the route that we have followed since we left the coast?" "If I can manage to do so," replied the doctor, "I will turn more directly northward, by from seven to eight degrees; I shall then endeavor to ascend toward the presumed latitudes of the sources of the Nile; perhaps we may discover some traces of Captain Speke's expedition or of M. de Heuglin's caravan. Unless I am mistaken, we are at thirty-two degrees forty minutes east longitude, and I should like to ascend directly north of the equator." "Look there!" exclaimed Kennedy, suddenly, "see those hippopotami sliding out of the pools--those masses of blood-colored flesh--and those crocodiles snuffing the air aloud!" "They're choking!" ejaculated Joe. "Ah! what a fine way to travel this is; and how one can snap his fingers at all that vermin!--Doctor! Mr. Kennedy! see those packs of wild animals hurrying along close together. There are fully two hundred. Those are wolves." "No! Joe, not wolves, but wild dogs; a famous breed that does not hesitate to attack the lion himself. They are the worst customers a traveller could meet, for they would instantly tear him to pieces." "Well, it isn't Joe that'll undertake to muzzle them!" responded that amiable youth. "After all, though, if that's the nature of the beast, we mustn't be too hard on them for it!" Silence gradually settled down under the influence of the impending storm: the thickened air actually seemed no longer adapted to the transmission of sound; the atmosphere appeared MUFFLED, and, like a room hung with tapestry, lost all its sonorous reverberation. The "rover bird" so-called, the coroneted crane, the red and blue jays, the mocking-bird, the flycatcher, disappeared among the foliage of the immense trees, and all nature revealed symptoms of some approaching catastrophe. At nine o'clock the Victoria hung motionless over Msene, an extensive group of villages scarcely distinguishable in the gloom. Once in a while, the reflection of a wandering ray of light in the dull water disclosed a succession of ditches regularly arranged, and, by one last gleam, the eye could make out the calm and sombre forms of palm-trees, sycamores, and gigantic euphorbiae. "I am stifling!" said the Scot, inhaling, with all the power of his lungs, as much as possible of the rarefied air. "We are not moving an inch! Let us descend!" "But the tempest!" said the doctor, with much uneasiness. "If you are afraid of being carried away by the wind, it seems to me that there is no other course to pursue." "Perhaps the storm won't burst to-night," said Joe; "the clouds are very high." "That is just the thing that makes me hesitate about going beyond them; we should have to rise still higher, lose sight of the earth, and not know all night whether we were moving forward or not, or in what direction we were going." "Make up your mind, dear doctor, for time presses!" "It's a pity that the wind has fallen," said Joe, again; "it would have carried us clear of the storm." "It is, indeed, a pity, my friends," rejoined the doctor. "The clouds are dangerous for us; they contain opposing currents which might catch us in their eddies, and lightnings that might set on fire. Again, those perils avoided, the force of the tempest might hurl us to the ground, were we to cast our anchor in the tree-tops." "Then what shall we do?" "Well, we must try to get the balloon into a medium zone of the atmosphere, and there keep her suspended between the perils of the heavens and those of the earth. We have enough water for the cylinder, and our two hundred pounds of ballast are untouched. In case of emergency I can use them." "We will keep watch with you," said the hunter. "No, my friends, put the provisions under shelter, and lie down; I will rouse you, if it becomes necessary." "But, master, wouldn't you do well to take some rest yourself, as there's no danger close on us just now?" insisted poor Joe. "No, thank you, my good fellow, I prefer to keep awake. We are not moving, and should circumstances not change, we'll find ourselves to-morrow in exactly the same place." "Good-night, then, sir!" "Good-night, if you can only find it so!" Kennedy and Joe stretched themselves out under their blankets, and the doctor remained alone in the immensity of space. However, the huge dome of clouds visibly descended, and the darkness became profound. The black vault closed in upon the earth as if to crush it in its embrace. All at once a violent, rapid, incisive flash of lightning pierced the gloom, and the rent it made had not closed ere a frightful clap of thunder shook the celestial depths. "Up! up! turn out!" shouted Ferguson. The two sleepers, aroused by the terrible concussion, were at the doctor's orders in a moment. "Shall we descend?" said Kennedy. "No! the balloon could not stand it. Let us go up before those clouds dissolve in water, and the wind is let loose!" and, so saying, the doctor actively stirred up the flame of the cylinder, and turned it on the spirals of the serpentine siphon. The tempests of the tropics develop with a rapidity equalled only by their violence. A second flash of lightning rent the darkness, and was followed by a score of others in quick succession. The sky was crossed and dotted, like the zebra's hide, with electric sparks, which danced and flickered beneath the great drops of rain. "We have delayed too long," exclaimed the doctor; "we must now pass through a zone of fire, with our balloon filled as it is with inflammable gas!" "But let us descend, then! let us descend!" urged Kennedy. "The risk of being struck would be just about even, and we should soon be torn to pieces by the branches of the trees!" "We are going up, doctor!" "Quicker, quicker still!" In this part of Africa, during the equatorial storms, it is not rare to count from thirty to thirty-five flashes of lightning per minute. The sky is literally on fire, and the crashes of thunder are continuous. The wind burst forth with frightful violence in this burning atmosphere; it twisted the blazing clouds; one might have compared it to the breath of some gigantic bellows, fanning all this conflagration. Dr. Ferguson kept his cylinder at full heat, and the balloon dilated and went up, while Kennedy, on his knees, held together the curtains of the awning. The balloon whirled round wildly enough to make their heads turn, and the aeronauts got some very alarming jolts, indeed, as their machine swung and swayed in all directions. Huge cavities would form in the silk of the balloon as the wind fiercely bent it in, and the stuff fairly cracked like a pistol as it flew back from the pressure. A sort of hail, preceded by a rumbling noise, hissed through the air and rattled on the covering of the Victoria. The latter, however, continued to ascend, while the lightning described tangents to the convexity of her circumference; but she bore on, right through the midst of the fire. "God protect us!" said Dr. Ferguson, solemnly, "we are in His hands; He alone can save us--but let us be ready for every event, even for fire--our fall could not be very rapid." The doctor's voice could scarcely be heard by his companions; but they could see his countenance calm as ever even amid the flashing of the lightnings; he was watching the phenomena of phosphorescence produced by the fires of St. Elmo, that were now skipping to and fro along the network of the balloon. The latter whirled and swung, but steadily ascended, and, ere the hour was over, it had passed the stormy belt. The electric display was going on below it like a vast crown of artificial fireworks suspended from the car. Then they enjoyed one of the grandest spectacles that Nature can offer to the gaze of man. Below them, the tempest; above them, the starry firmament, tranquil, mute, impassible, with the moon projecting her peaceful rays over these angry clouds. Dr. Ferguson consulted the barometer; it announced twelve thousand feet of elevation. It was then eleven o'clock at night. "Thank Heaven, all danger is past; all we have to do now, is, to keep ourselves at this height," said the doctor. "It was frightful!" remarked Kennedy. "Oh!" said Joe, "it gives a little variety to the trip, and I'm not sorry to have seen a storm from a trifling distance up in the air. It's a fine sight!"
CHAPTER SEVENTEENTH. The Mountains of the Moon.--An Ocean of Verdure.--They cast Anchor.--The Towing Elephant.--A Running Fire.--Death of the Monster.--The Field-Oven.--A Meal on the Grass.--A Night on the Ground. About four in the morning, Monday, the sun reappeared in the horizon; the clouds had dispersed, and a cheery breeze refreshed the morning dawn. The earth, all redolent with fragrant exhalations, reappeared to the gaze of our travellers. The balloon, whirled about by opposing currents, had hardly budged from its place, and the doctor, letting the gas contract, descended so as to get a more northerly direction. For a long while his quest was fruitless; the wind carried him toward the west until he came in sight of the famous Mountains of the Moon, which grouped themselves in a semicircle around the extremity of Lake Tanganayika; their ridges, but slightly indented, stood out against the bluish horizon, so that they might have been mistaken for a natural fortification, not to be passed by the explorers of the centre of Africa. Among them were a few isolated cones, revealing the mark of the eternal snows. "Here we are at last," said the doctor, "in an unexplored country! Captain Burton pushed very far to the westward, but he could not reach those celebrated mountains; he even denied their existence, strongly as it was affirmed by Speke, his companion. He pretended that they were born in the latter's fancy; but for us, my friends, there is no further doubt possible." "Shall we cross them?" asked Kennedy. "Not, if it please God. I am looking for a wind that will take me back toward the equator. I will even wait for one, if necessary, and will make the balloon like a ship that casts anchor, until favorable breezes come up." But the foresight of the doctor was not long in bringing its reward; for, after having tried different heights, the Victoria at length began to sail off to the northeastward with medium speed. "We are in the right track," said the doctor, consulting his compass, "and scarcely two hundred feet from the surface; lucky circumstances for us, enabling us, as they do, to reconnoitre these new regions. When Captain Speke set out to discover Lake Ukereoue, he ascended more to the eastward in a straight line above Kazeh." "Shall we keep on long in this way?" inquired the Scot. "Perhaps. Our object is to push a point in the direction of the sources of the Nile; and we have more than six hundred miles to make before we get to the extreme limit reached by the explorers who came from the north." "And we shan't set foot on the solid ground?" murmured Joe; "it's enough to cramp a fellow's legs!" "Oh, yes, indeed, my good Joe," said the doctor, reassuring him; "we have to economize our provisions, you know; and on the way, Dick, you must get us some fresh meat." "Whenever you like, doctor." "We shall also have to replenish our stock of water. Who knows but we may be carried to some of the dried-up regions? So we cannot take too many precautions." At noon the Victoria was at twenty-nine degrees fifteen minutes east longitude, and three degrees fifteen minutes south latitude. She passed the village of Uyofu, the last northern limit of the Unyamwezi, opposite to the Lake Ukereoue, which could still be seen. The tribes living near to the equator seem to be a little more civilized, and are governed by absolute monarchs, whose control is an unlimited despotism. Their most compact union of power constitutes the province of Karagwah. It was decided by the aeronauts that they would alight at the first favorable place. They found that they should have to make a prolonged halt, and take a careful inspection of the balloon: so the flame of the cylinder was moderated, and the anchors, flung out from the car, ere long began to sweep the grass of an immense prairie, that, from a certain height, looked like a shaven lawn, but the growth of which, in reality, was from seven to eight feet in height. The balloon skimmed this tall grass without bending it, like a gigantic butterfly: not an obstacle was in sight; it was an ocean of verdure without a single breaker. "We might proceed a long time in this style," remarked Kennedy; "I don't see one tree that we could approach, and I'm afraid that our hunt's over." "Wait, Dick; you could not hunt anyhow in this grass, that grows higher than your head. We'll find a favorable place presently." In truth, it was a charming excursion that they were making now--a veritable navigation on this green, almost transparent sea, gently undulating in the breath of the wind. The little car seemed to cleave the waves of verdure, and, from time to time, coveys of birds of magnificent plumage would rise fluttering from the tall herbage, and speed away with joyous cries. The anchors plunged into this lake of flowers, and traced a furrow that closed behind them, like the wake of a ship. All at once a sharp shock was felt--the anchor had caught in the fissure of some rock hidden in the high grass. "We are fast!" exclaimed Joe. These words had scarcely been uttered when a shrill cry rang through the air, and the following phrases, mingled with exclamations, escaped from the lips of our travellers: "What's that?" "A strange cry!" "Look! Why, we're moving!" "The anchor has slipped!" "No; it holds, and holds fast too!" said Joe, who was tugging at the rope. "It's the rock, then, that's moving!" An immense rustling was noticed in the grass, and soon an elongated, winding shape was seen rising above it. "A serpent!" shouted Joe. "A serpent!" repeated Kennedy, handling his rifle. "No," said the doctor, "it's an elephant's trunk!" "An elephant, Samuel?" And, as Kennedy said this, he drew his rifle to his shoulder. "Wait, Dick; wait!" "That's a fact! The animal's towing us!" "And in the right direction, Joe--in the right direction." The elephant was now making some headway, and soon reached a clearing where his whole body could be seen. By his gigantic size, the doctor recognized a male of a superb species. He had two whitish tusks, beautifully curved, and about eight feet in length; and in these the shanks of the anchor had firmly caught. The animal was vainly trying with his trunk to disengage himself from the rope that attached him to the car. "Get up--go ahead, old fellow!" shouted Joe, with delight, doing his best to urge this rather novel team. "Here is a new style of travelling!--no more horses for me. An elephant, if you please!" "But where is he taking us to?" said Kennedy, whose rifle itched in his grasp. "He's taking us exactly to where we want to go, my dear Dick. A little patience!" "'Wig-a-more! wig-a-more!' as the Scotch country folks say," shouted Joe, in high glee. "Gee-up! gee-up there!" The huge animal now broke into a very rapid gallop. He flung his trunk from side to side, and his monstrous bounds gave the car several rather heavy thumps. Meanwhile the doctor stood ready, hatchet in hand, to cut the rope, should need arise. "But," said he, "we shall not give up our anchor until the last moment." This drive, with an elephant for the team, lasted about an hour and a half; yet the animal did not seem in the least fatigued. These immense creatures can go over a great deal of ground, and, from one day to another, are found at enormous distances from there they were last seen, like the whales, whose mass and speed they rival. "In fact," said Joe, "it's a whale that we have harpooned; and we're only doing just what whalemen do when out fishing." But a change in the nature of the ground compelled the doctor to vary his style of locomotion. A dense grove of calmadores was descried on the horizon, about three miles away, on the north of the prairie. So it became necessary to detach the balloon from its draught-animal at last. Kennedy was intrusted with the job of bringing the elephant to a halt. He drew his rifle to his shoulder, but his position was not favorable to a successful shot; so that the first ball fired flattened itself on the animal's skull, as it would have done against an iron plate. The creature did not seem in the least troubled by it; but, at the sound of the discharge, he had increased his speed, and now was going as fast as a horse at full gallop. "The deuce!" ejaculated Kennedy. "What a solid head!" commented Joe. "We'll try some conical balls behind the shoulder-joint," said Kennedy, reloading his rifle with care. In another moment he fired. The animal gave a terrible cry, but went on faster than ever. "Come!" said Joe, taking aim with another gun, "I must help you, or we'll never end it." And now two balls penetrated the creature's side. The elephant halted, lifted his trunk, and resumed his run toward the wood with all his speed; he shook his huge head, and the blood began to gush from his wounds. "Let us keep up our fire, Mr. Kennedy." "And a continuous fire, too," urged the doctor, "for we are close on the woods." Ten shots more were discharged. The elephant made a fearful bound; the car and balloon cracked as though every thing were going to pieces, and the shock made the doctor drop his hatchet on the ground. The situation was thus rendered really very alarming; the anchor-rope, which had securely caught, could not be disengaged, nor could it yet be cut by the knives of our aeronauts, and the balloon was rushing headlong toward the wood, when the animal received a ball in the eye just as he lifted his head. On this he halted, faltered, his knees bent under him, and he uncovered his whole flank to the assaults of his enemies in the balloon. "A bullet in his heart!" said Kennedy, discharging one last rifle-shot. The elephant uttered a long bellow of terror and agony, then raised himself up for a moment, twirling his trunk in the air, and finally fell with all his weight upon one of his tusks, which he broke off short. He was dead. "His tusk's broken!" exclaimed Kennedy--"ivory too that in England would bring thirty-five guineas per hundred pounds." "As much as that?" said Joe, scrambling down to the ground by the anchor-rope. "What's the use of sighing over it, Dick?" said the doctor. "Are we ivory merchants? Did we come hither to make money?" Joe examined the anchor and found it solidly attached to the unbroken tusk. The doctor and Dick leaped out on the ground, while the balloon, now half emptied, hovered over the body of the huge animal. "What a splendid beast!" said Kennedy, "what a mass of flesh! I never saw an elephant of that size in India!" "There's nothing surprising about that, my dear Dick; the elephants of Central Africa are the finest in the world. The Andersons and the Cummings have hunted so incessantly in the neighborhood of the Cape, that these animals have migrated to the equator, where they are often met with in large herds." "In the mean while, I hope," added Joe, "that we'll taste a morsel of this fellow. I'll undertake to get you a good dinner at his expense. Mr. Kennedy will go off and hunt for an hour or two; the doctor will make an inspection of the balloon, and, while they're busy in that way, I'll do the cooking." "A good arrangement!" said the doctor; "so do as you like, Joe." "As for me," said the hunter, "I shall avail myself of the two hours' recess that Joe has condescended to let me have." "Go, my friend, but no imprudence! Don't wander too far away." "Never fear, doctor!" and, so saying, Dick, shouldering his gun, plunged into the woods. Forthwith Joe went to work at his vocation. At first he made a hole in the ground two feet deep; this he filled with the dry wood that was so abundantly scattered about, where it had been strewn by the elephants, whose tracks could be seen where they had made their way through the forest. This hole filled, he heaped a pile of fagots on it a foot in height, and set fire to it. Then he went back to the carcass of the elephant, which had fallen only about a hundred feet from the edge of the forest; he next proceeded adroitly to cut off the trunk, which might have been two feet in diameter at the base; of this he selected the most delicate portion, and then took with it one of the animal's spongy feet. In fact, these are the finest morsels, like the hump of the bison, the paws of the bear, and the head of the wild boar. When the pile of fagots had been thoroughly consumed, inside and outside, the hole, cleared of the cinders and hot coals, retained a very high temperature. The pieces of elephant-meat, surrounded with aromatic leaves, were placed in this extempore oven and covered with hot coals. Then Joe piled up a second heap of sticks over all, and when it had burned out the meat was cooked to a turn. Then Joe took the viands from the oven, spread the savory mess upon green leaves, and arranged his dinner upon a magnificent patch of greensward. He finally brought out some biscuit, some coffee, and some cognac, and got a can of pure, fresh water from a neighboring streamlet. The repast thus prepared was a pleasant sight to behold, and Joe, without being too proud, thought that it would also be pleasant to eat. "A journey without danger or fatigue," he soliloquized; "your meals when you please; a swinging hammock all the time! What more could a man ask? And there was Kennedy, who didn't want to come!" On his part, Dr. Ferguson was engrossed in a serious and thorough examination of the balloon. The latter did not appear to have suffered from the storm; the silk and the gutta percha had resisted wonderfully, and, upon estimating the exact height of the ground and the ascensional force of the balloon, our aeronaut saw, with satisfaction, that the hydrogen was in exactly the same quantity as before. The covering had remained completely waterproof. It was now only five days since our travellers had quitted Zanzibar; their pemmican had not yet been touched; their stock of biscuit and potted meat was enough for a long trip, and there was nothing to be replenished but the water. The pipes and spiral seemed to be in perfect condition, since, thanks to their india-rubber jointings, they had yielded to all the oscillations of the balloon. His examination ended, the doctor betook himself to setting his notes in order. He made a very accurate sketch of the surrounding landscape, with its long prairie stretching away out of sight, the forest of calmadores, and the balloon resting motionless over the body of the dead elephant. At the end of his two hours, Kennedy returned with a string of fat partridges and the haunch of an oryx, a sort of gemsbok belonging to the most agile species of antelopes. Joe took upon himself to prepare this surplus stock of provisions for a later repast. "But, dinner's ready!" he shouted in his most musical voice. And the three travellers had only to sit down on the green turf. The trunk and feet of the elephant were declared to be exquisite. Old England was toasted, as usual, and delicious Havanas perfumed this charming country for the first time. Kennedy ate, drank, and chatted, like four; he was perfectly delighted with his new life, and seriously proposed to the doctor to settle in this forest, to construct a cabin of boughs and foliage, and, there and then, to lay the foundation of a Robinson Crusoe dynasty in Africa. The proposition went no further, although Joe had, at once, selected the part of Man Friday for himself. The country seemed so quiet, so deserted, that the doctor resolved to pass the night on the ground, and Joe arranged a circle of watch-fires as an indispensable barrier against wild animals, for the hyenas, cougars, and jackals, attracted by the smell of the dead elephant, were prowling about in the neighborhood. Kennedy had to fire his rifle several times at these unceremonious visitors, but the night passed without any untoward occurrence.
