thousand miles. Well, at the rate of two hundred and forty miles every twelve hours, which does not come near the rapidity of our railroad trains, by travelling day and night, it would take only seven days to cross Africa!” “But then you could see nothing, make no geographical observations, or reconnoitre the face of the country.” “Ah!” replied the doctor, “if I am master of my balloon--if I can ascend and descend at will, I shall stop when I please, especially when too violent currents of air threaten to carry me out of my way with them.” “And you will encounter such,” said Captain Bennet. “There are tornadoes that sweep at the rate of more than two hundred and forty miles per hour.” “You see, then, that with such speed as that, we could cross Africa in twelve hours. One would rise at Zanzibar, and go to bed at St. Louis!” “But,” rejoined the officer, “could any balloon withstand the wear and tear of such velocity?” “It has happened before,” replied Ferguson. “And the balloon withstood it?” “Perfectly well. It was at the time of the coronation of Napoleon, in 1804. The aeronaut, Gernerin, sent up a balloon at Paris, about eleven o’clock in the evening. It bore the following inscription, in letters of gold: ‘Paris, 25 Frimaire; year XIII; Coronation of the Emperor Napoleon by his Holiness, Pius VII.’ On the next morning, the inhabitants of Rome saw the same balloon soaring above the Vatican, whence it crossed the Campagna, and finally fluttered down into the lake of Bracciano. So you see, gentlemen, that a balloon can resist such velocities.” “A balloon--that might be; but a man?” insinuated Kennedy. “Yes, a man, too!--for the balloon is always motionless with reference to the air that surrounds it. What moves is the mass of the atmosphere itself: for instance, one may light a taper in the car, and the flame will not even waver. An aeronaut in Garnerin’s balloon would not have suffered in the least from the speed. But then I have no occasion to attempt such velocity; and if I can anchor to some tree, or some favorable inequality of the ground, at night, I shall not fail to do so. Besides, we take provision for two months with us, after all; and there is nothing to prevent our skilful huntsman here from furnishing game in abundance when we come to alight.” “Ah! Mr. Kennedy,” said a young midshipman, with envious eyes, “what splendid shots you’ll have!” “Without counting,” said another, “that you’ll have the glory as well as the sport!” “Gentlemen,” replied the hunter, stammering with confusion, “I greatly--appreciate--your compliments--but they--don’t--belong to me.” “You!” exclaimed every body, “don’t you intend to go?” “I am not going!” “You won’t accompany Dr. Ferguson?” “Not only shall I not accompany him, but I am here so as to be present at the last moment to prevent his going.” Every eye was now turned to the doctor. “Never mind him!” said the latter, calmly. “This is a matter that we can’t argue with him. At heart he knows perfectly well that he IS going.” “By Saint Andrew!” said Kennedy, “I swear--” “Swear to nothing, friend Dick; you have been ganged and weighed--you and your powder, your guns, and your bullets; so don’t let us say anything more about it.” And, in fact, from that day until the arrival at Zanzibar, Dick never opened his mouth. He talked neither about that nor about anything else. He kept absolutely silent. CHAPTER NINTH. They double the Cape.--The Forecastle.--A Course of Cosmography by Professor Joe.--Concerning the Method of guiding Balloons.--How to seek out Atmospheric Currents.--Eureka. The Resolute plunged along rapidly toward the Cape of Good Hope, the weather continuing fine, although the sea ran heavier. On the 30th of March, twenty-seven days after the departure from London, the Table Mountain loomed up on the horizon. Cape City lying at the foot of an amphitheatre of hills, could be distinguished through the ship’s glasses, and soon the Resolute cast anchor in the port. But the captain touched there only to replenish his coal bunkers, and that was but a day’s job. On the morrow, he steered away to the south’ard, so as to double the southernmost point of Africa, and enter the Mozambique Channel. This was not Joe’s first sea-voyage, and so, for his part, he soon found himself at home on board; every body liked him for his frankness and good-humor. A considerable share of his master’s renown was reflected upon him. He was listened to as an oracle, and he made no more mistakes than the next one. So, while the doctor was pursuing his descriptive course of lecturing in the officers’ mess, Joe reigned supreme on the forecastle, holding forth in his own peculiar manner, and making history to suit himself--a style of procedure pursued, by the way, by the greatest historians of all ages and nations. The topic of discourse was, naturally, the aerial voyage. Joe had experienced some trouble in getting the rebellious spirits to believe in it; but, once accepted by them, nothing connected with it was any longer an impossibility to the imaginations of the seamen stimulated by Joe’s harangues. Our dazzling narrator persuaded his hearers that, after this trip, many others still more wonderful would be undertaken. In fact, it was to be but the first of a long series of superhuman expeditions. “You see, my friends, when a man has had a taste of that kind of travelling, he can’t get along afterward with any other; so, on our next expedition, instead of going off to one side, we’ll go right ahead, going up, too, all the time.” “Humph! then you’ll go to the moon!” said one of the crowd, with a stare of amazement. “To the moon!” exclaimed Joe, “To the moon! pooh! that’s too common. Every body might go to the moon, that way. Besides, there’s no water there, and you have to carry such a lot of it along with you. Then you have to take air along in bottles, so as to breathe.” “Ay! ay! that’s all right! But can a man get a drop of the real stuff there?” said a sailor who liked his toddy. “Not a drop!” was Joe’s answer. “No! old fellow, not in the moon. But we’re going to skip round among those little twinklers up there--the stars--and the splendid planets that my old man so often talks about. For instance, we’ll commence with Saturn--” “That one with the ring?” asked the boatswain. “Yes! the wedding-ring--only no one knows what’s become of his wife!” “What? will you go so high up as that?” said one of the ship-boys, gaping with wonder. “Why, your master must be Old Nick himself.” “Oh! no, he’s too good for that.” “But, after Saturn--what then?” was the next inquiry of his impatient audience. “After Saturn? Well, we’ll visit Jupiter. A funny place that is, too, where the days are only nine hours and a half long--a good thing for the lazy fellows--and the years, would you believe it--last twelve of ours, which is fine for folks who have only six months to live. They get off a little longer by that.” “Twelve years!” ejaculated the boy. “Yes, my youngster; so that in that country you’d be toddling after your mammy yet, and that old chap yonder, who looks about fifty, would only be a little shaver of four and a half.” “Blazes! that’s a good ‘un!” shouted the whole forecastle together. “Solemn truth!” said Joe, stoutly. “But what can you expect? When people will stay in this world, they learn nothing and keep as ignorant as bears. But just come along to Jupiter and you’ll see. But they have to look out up there, for he’s got satellites that are not just the easiest things to pass.” All the men laughed, but they more than half believed him. Then he went on to talk about Neptune, where seafaring men get a jovial reception, and Mars, where the military get the best of the sidewalk to such an extent that folks can hardly stand it. Finally, he drew them a heavenly picture of the delights of Venus. “And when we get back from that expedition,” said the indefatigable narrator, “they’ll decorate us with the Southern Cross that shines up there in the Creator’s button-hole.” “Ay, and you’d have well earned it!” said the sailors. Thus passed the long evenings on the forecastle in merry chat, and during the same time the doctor went on with his instructive discourses. One day the conversation turned upon the means of directing balloons, and the doctor was asked his opinion about it. “I don’t think,” said he, “that we shall succeed in finding out a system of directing them. I am familiar with all the plans attempted and proposed, and not one has succeeded, not one is practicable. You may readily understand that I have occupied my mind with this subject, which was, necessarily, so interesting to me, but I have not been able to solve the problem with the appliances now known to mechanical science. We would have to discover a motive power of extraordinary force, and almost impossible lightness of machinery. And, even then, we could not resist atmospheric currents of any considerable strength. Until now, the effort has been rather to direct the car than the balloon, and that has been one great error.” “Still there are many points of resemblance between a balloon and a ship which is directed at will.” “Not at all,” retorted the doctor, “there is little or no similarity between the two cases. Air is infinitely less dense than water, in which the ship is only half submerged, while the whole bulk of a balloon is plunged in the atmosphere, and remains motionless with reference to the element that surrounds it.” “You think, then, that aerostatic science has said its last word?” “Not at all! not at all! But we must look for another point in the case, and if we cannot manage to guide our balloon, we must, at least, try to keep it in favorable aerial currents. In proportion as we ascend, the latter become much more uniform and flow more constantly in one direction. They are no longer disturbed by the mountains and valleys that traverse the surface of the globe, and these, you know, are the chief cause of the variations of the wind and the inequality of their force. Therefore, these zones having been once determined, the balloon will merely have to be placed in the currents best adapted to its destination.” “But then,” continued Captain Bennet, “in order to reach them, you must keep constantly ascending or descending. That is the real difficulty, doctor.” “And why, my dear captain?” “Let us understand one another. It would be a difficulty and an obstacle only for long journeys, and not for short aerial excursions.” “And why so, if you please?” “Because you can ascend only by throwing out ballast; you can descend only after letting off gas, and by these processes your ballast and your gas are soon exhausted.” “My dear sir, that’s the whole question. There is the only difficulty that science need now seek to overcome. The problem is not how to guide the balloon, but how to take it up and down without expending the gas which is its strength, its life-blood, its soul, if I may use the expression.” “You are right, my dear doctor; but this problem is not yet solved; this means has not yet been discovered.” “I beg your pardon, it HAS been discovered.” “By whom?” “By me!” “By you?” “You may readily believe that otherwise I should not have risked this expedition across Africa in a balloon. In twenty-four hours I should have been without gas!” “But you said nothing about that in England?” “No! I did not want to have myself overhauled in public. I saw no use in that. I made my preparatory experiments in secret and was satisfied. I have no occasion, then, to learn any thing more from them.” “Well! doctor, would it be proper to ask what is your secret?” “Here it is, gentlemen--the simplest thing in the world!” The attention of his auditory was now directed to the doctor in the utmost degree as he quietly proceeded with his explanation. 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. . , 1 , 2 , , 3 ! » 4 5 « , , 6 . » 7 8 « ! » , « - - 9 , , 10 . » 11 12 « , » . « 13 14 . » 15 16 « , , , 17 . , . ! » 18 19 « , » , « 20 ?
