"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.



CHAPTER EIGHTEENTH.

The Karagwah.—Lake Ukereoue.—A Night on an Island.—The Equator.— Crossing the Lake.—The Cascades.—A View of the Country.—The Sources of the Nile.—The Island of Benga.—The Signature of Andrea Debono.—The Flag with the Arms of England.

At five o'clock in the morning, preparations for departure commenced. Joe, with the hatchet which he had fortunately recovered, broke the elephant's tusks. The balloon, restored to liberty, sped away to the northwest with our travellers, at the rate of eighteen miles per hour.

The doctor had carefully taken his position by the altitude of the stars, during the preceding night. He knew that he was in latitude two degrees forty minutes below the equator, or at a distance of one hundred and sixty geographical miles. He swept along over many villages without heeding the cries that the appearance of the balloon excited; he took note of the conformation of places with quick sights; he passed the slopes of the Rubemhe, which are nearly as abrupt as the summits of the Ousagara, and, farther on, at Tenga, encountered the first projections of the Karagwah chains, which, in his opinion, are direct spurs of the Mountains of the Moon. So, the ancient legend which made these mountains the cradle of the Nile, came near to the truth, since they really border upon Lake Ukereoue, the conjectured reservoir of the waters of the great river.

From Kafuro, the main district of the merchants of that country, he descried, at length, on the horizon, the lake so much desired and so long sought for, of which Captain Speke caught a glimpse on the 3d of August, 1858.

Samuel Ferguson felt real emotion: he was almost in contact with one of the principal points of his expedition, and, with his spy-glass constantly raised, he kept every nook and corner of the mysterious region in sight. His gaze wandered over details that might have been thus described:

"Beneath him extended a country generally destitute of cultivation; only here and there some ravines seemed under tillage; the surface, dotted with peaks of medium height, grew flat as it approached the lake; barley-fields took the place of rice-plantations, and there, too, could be seen growing the species of plantain from which the wine of the country is drawn, and mwani, the wild plant which supplies a substitute for coffee. A collection of some fifty or more circular huts, covered with a flowering thatch, constituted the capital of the Karagwah country."

He could easily distinguish the astonished countenances of a rather fine-looking race of natives of yellowish-brown complexion. Women of incredible corpulence were dawdling about through the cultivated grounds, and the doctor greatly surprised his companions by informing them that this rotundity, which is highly esteemed in that region, was obtained by an obligatory diet of curdled milk.

At noon, the Victoria was in one degree forty-five minutes south latitude, and at one o'clock the wind was driving her directly toward the lake.

This sheet of water was christened Uyanza Victoria, or Victoria Lake, by Captain Speke. At the place now mentioned it might measure about ninety miles in breadth, and at its southern extremity the captain found a group of islets, which he named the Archipelago of Bengal. He pushed his survey as far as Muanza, on the eastern coast, where he was received by the sultan. He made a triangulation of this part of the lake, but he could not procure a boat, either to cross it or to visit the great island of Ukereoue which is very populous, is governed by three sultans, and appears to be only a promontory at low tide.

The balloon approached the lake more to the northward, to the doctor's great regret, for it had been his wish to determine its lower outlines. Its shores seemed to be thickly set with brambles and thorny plants, growing together in wild confusion, and were literally hidden, sometimes, from the gaze, by myriads of mosquitoes of a light-brown hue. The country was evidently habitable and inhabited. Troops of hippopotami could be seen disporting themselves in the forests of reeds, or plunging beneath the whitish waters of the lake.

The latter, seen from above, presented, toward the west, so broad an horizon that it might have been called a sea; the distance between the two shores is so great that communication cannot be established, and storms are frequent and violent, for the winds sweep with fury over this elevated and unsheltered basin.

The doctor experienced some difficulty in guiding his course; he was afraid of being carried toward the east, but, fortunately, a current bore him directly toward the north, and at six o'clock in the evening the balloon alighted on a small desert island in thirty minutes south latitude, and thirty-two degrees fifty-two minutes east longitude, about twenty miles from the shore.

The travellers succeeded in making fast to a tree, and, the wind having fallen calm toward evening, they remained quietly at anchor. They dared not dream of taking the ground, since here, as on the shores of the Uyanza, legions of mosquitoes covered the soil in dense clouds. Joe even came back, from securing the anchor in the tree, speckled with bites, but he kept his temper, because he found it quite the natural thing for mosquitoes to treat him as they had done.

Nevertheless, the doctor, who was less of an optimist, let out as much rope as he could, so as to escape these pitiless insects, that began to rise toward him with a threatening hum.

The doctor ascertained the height of the lake above the level of the sea, as it had been determined by Captain Speke, say three thousand seven hundred and fifty feet.

"Here we are, then, on an island!" said Joe, scratching as though he'd tear his nails out.

"We could make the tour of it in a jiffy," added Kennedy, "and, excepting these confounded mosquitoes, there's not a living being to be seen on it."

"The islands with which the lake is dotted," replied the doctor, "are nothing, after all, but the tops of submerged hills; but we are lucky to have found a retreat among them, for the shores of the lake are inhabited by ferocious tribes. Take your sleep, then, since Providence has granted us a tranquil night."

"Won't you do the same, doctor?"

"No, I could not close my eyes. My thoughts would banish sleep. To-morrow, my friends, should the wind prove favorable, we shall go due north, and we shall, perhaps, discover the sources of the Nile, that grand secret which has so long remained impenetrable. Near as we are to the sources of the renowned river, I could not sleep."

Kennedy and Joe, whom scientific speculations failed to disturb to that extent, were not long in falling into sound slumber, while the doctor held his post.

On Wednesday, April 23d, the balloon started at four o'clock in the morning, with a grayish sky overhead; night was slow in quitting the surface of the lake, which was enveloped in a dense fog, but presently a violent breeze scattered all the mists, and, after the balloon had been swung to and fro for a moment, in opposite directions, it at length veered in a straight line toward the north.

Dr. Ferguson fairly clapped his hands for joy.

"We are on the right track!" he exclaimed. "To-day or never we shall see the Nile! Look, my friends, we are crossing the equator! We are entering our own hemisphere!"

"Ah!" said Joe, "do you think, doctor, that the equator passes here?"

"Just here, my boy!"

"Well, then, with all respect to you, sir, it seems to me that this is the very time to moisten it."

"Good!" said the doctor, laughing. "Let us have a glass of punch. You have a way of comprehending cosmography that is any thing but dull."

And thus was the passage of the Victoria over the equator duly celebrated.

The balloon made rapid headway. In the west could be seen a low and but slightly-diversified coast, and, farther away in the background, the elevated plains of the Uganda and the Usoga. At length, the rapidity of the wind became excessive, approaching thirty miles per hour.

The waters of the Nyanza, violently agitated, were foaming like the billows of a sea. By the appearance of certain long swells that followed the sinking of the waves, the doctor was enabled to conclude that the lake must have great depth of water. Only one or two rude boats were seen during this rapid passage.

"This lake is evidently, from its elevated position, the natural reservoir of the rivers in the eastern part of Africa, and the sky gives back to it in rain what it takes in vapor from the streams that flow out of it. I am certain that the Nile must here take its rise."

"Well, we shall see!" said Kennedy.

About nine o'clock they drew nearer to the western coast. It seemed deserted, and covered with woods; the wind freshened a little toward the east, and the other shore of the lake could be seen. It bent around in such a curve as to end in a wide angle toward two degrees forty minutes north latitude. Lofty mountains uplifted their arid peaks at this extremity of Nyanza; but, between them, a deep and winding gorge gave exit to a turbulent and foaming river.

While busy managing the balloon, Dr. Ferguson never ceased reconnoitring the country with eager eyes.

"Look!" he exclaimed, "look, my friends! the statements of the Arabs were correct! They spoke of a river by which Lake Ukereoue discharged its waters toward the north, and this river exists, and we are descending it, and it flows with a speed analogous to our own! And this drop of water now gliding away beneath our feet is, beyond all question, rushing on, to mingle with the Mediterranean! It is the Nile!"

"It is the Nile!" reeechoed Kennedy, carried away by the enthusiasm of his friend.

"Hurrah for the Nile!" shouted Joe, glad, and always ready to cheer for something.

Enormous rocks, here and there, embarrassed the course of this mysterious river. The water foamed as it fell in rapids and cataracts, which confirmed the doctor in his preconceived ideas on the subject. From the environing mountains numerous torrents came plunging and seething down, and the eye could take them in by hundreds. There could be seen, starting from the soil, delicate jets of water scattering in all directions, crossing and recrossing each other, mingling, contending in the swiftness of their progress, and all rushing toward that nascent stream which became a river after having drunk them in.

"Here is, indeed, the Nile!" reiterated the doctor, with the tone of profound conviction. "The origin of its name, like the origin of its waters, has fired the imagination of the learned; they have sought to trace it from the Greek, the Coptic, the Sanscrit; but all that matters little now, since we have made it surrender the secret of its source!"

"But," said the Scotchman, "how are you to make sure of the identity of this river with the one recognized by the travellers from the north?"

"We shall have certain, irrefutable, convincing, and infallible proof," replied Ferguson, "should the wind hold another hour in our favor!"

The mountains drew farther apart, revealing in their place numerous villages, and fields of white Indian corn, doura, and sugar-cane. The tribes inhabiting the region seemed excited and hostile; they manifested more anger than adoration, and evidently saw in the aeronauts only obtrusive strangers, and not condescending deities. It appeared as though, in approaching the sources of the Nile, these men came to rob them of something, and so the Victoria had to keep out of range of their muskets.

"To land here would be a ticklish matter!" said the Scot.

"Well!" said Joe, "so much the worse for these natives. They'll have to do without the pleasure of our conversation."

"Nevertheless, descend I must," said the doctor, "were it only for a quarter of an hour. Without doing so I cannot verify the results of our expedition."

"It is indispensable, then, doctor?"

"Indispensable; and we will descend, even if we have to do so with a volley of musketry."

"The thing suits me," said Kennedy, toying with his pet rifle.

"And I'm ready, master, whenever you say the word!" added Joe, preparing for the fight.

"It would not be the first time," remarked the doctor, "that science has been followed up, sword in hand. The same thing happened to a French savant among the mountains of Spain, when he was measuring the terrestrial meridian."

"Be easy on that score, doctor, and trust to your two body-guards."

"Are we there, master?"

"Not yet. In fact, I shall go up a little, first, in order to get an exact idea of the configuration of the country."

The hydrogen expanded, and in less than ten minutes the balloon was soaring at a height of twenty-five hundred feet above the ground.

From that elevation could be distinguished an inextricable network of smaller streams which the river received into its bosom; others came from the west, from between numerous hills, in the midst of fertile plains.

"We are not ninety miles from Gondokoro," said the doctor, measuring off the distance on his map, "and less than five miles from the point reached by the explorers from the north. Let us descend with great care."

And, upon this, the balloon was lowered about two thousand feet.

"Now, my friends, let us be ready, come what may."

"Ready it is!" said Dick and Joe, with one voice.

"Good!"

In a few moments the balloon was advancing along the bed of the river, and scarcely one hundred feet above the ground. The Nile measured but fifty fathoms in width at this point, and the natives were in great excitement, rushing to and fro, tumultuously, in the villages that lined the banks of the stream. At the second degree it forms a perpendicular cascade of ten feet in height, and consequently impassable by boats.

"Here, then, is the cascade mentioned by Debono!" exclaimed the doctor.

The basin of the river spread out, dotted with numerous islands, which Dr. Ferguson devoured with his eyes. He seemed to be seeking for a point of reference which he had not yet found.

By this time, some blacks, having ventured in a boat just under the balloon, Kennedy saluted them with a shot from his rifle, that made them regain the bank at their utmost speed.

"A good journey to you," bawled Joe, "and if I were in your place, I wouldn't try coming back again. I should be mightily afraid of a monster that can hurl thunderbolts when he pleases."

But, all at once, the doctor snatched up his spy-glass, and directed it toward an island reposing in the middle of the river.

"Four trees!" he exclaimed; "look, down there!" Sure enough, there were four trees standing alone at one end of it.

"It is Bengal Island! It is the very same," repeated the doctor, exultingly.

"And what of that?" asked Dick.

"It is there that we shall alight, if God permits."

"But, it seems to be inhabited, doctor."

"Joe is right; and, unless I'm mistaken, there is a group of about a score of natives on it now."

"We'll make them scatter; there'll be no great trouble in that," responded Ferguson.

"So be it," chimed in the hunter.

The sun was at the zenith as the balloon approached the island.

The blacks, who were members of the Makado tribe, were howling lustily, and one of them waved his bark hat in the air. Kennedy took aim at him, fired, and his hat flew about him in pieces. Thereupon there was a general scamper. The natives plunged headlong into the river, and swam to the opposite bank. Immediately, there came a shower of balls from both banks, along with a perfect cloud of arrows, but without doing the balloon any damage, where it rested with its anchor snugly secured in the fissure of a rock. Joe lost no time in sliding to the ground.

"The ladder!" cried the doctor. "Follow me, Kennedy."

"What do you wish, sir?"

"Let us alight. I want a witness."

"Here I am!"

"Mind your post, Joe, and keep a good lookout."

"Never fear, doctor; I'll answer for all that."

"Come, Dick," said the doctor, as he touched the ground.

So saying, he drew his companion along toward a group of rocks that rose upon one point of the island; there, after searching for some time, he began to rummage among the brambles, and, in so doing, scratched his hands until they bled.

Suddenly he grasped Kennedy's arm, exclaiming: "Look! look!"

"Letters!"

Yes; there, indeed, could be descried, with perfect precision of outline, some letters carved on the rock. It was quite easy to make them out:

"A. D."

"A.D.!" repeated Dr. Ferguson. "Andrea Debono— the very signature of the traveller who farthest ascended the current of the Nile."

"No doubt of that, friend Samuel," assented Kennedy.

"Are you now convinced?"

"It is the Nile! We cannot entertain a doubt on that score now," was the reply.

The doctor, for the last time, examined those precious initials, the exact form and size of which he carefully noted.

"And now," said he—"now for the balloon!"

"Quickly, then, for I see some of the natives getting ready to recross the river."

"That matters little to us now. Let the wind but send us northward for a few hours, and we shall reach Gondokoro, and press the hands of some of our countrymen."

Ten minutes more, and the balloon was majestically ascending, while Dr. Ferguson, in token of success, waved the English flag triumphantly from his car.



CHAPTER NINETEENTH.

The Nile.—The Trembling Mountain.—A Remembrance of the Country.—The Narratives of the Arabs.—The Nyam-Nyams.—Joe's Shrewd Cogitations.—The Balloon runs the Gantlet.—Aerostatic Ascensions.—Madame Blanchard.

"Which way do we head?" asked Kennedy, as he saw his friend consulting the compass.

"North-northeast."

"The deuce! but that's not the north?"

"No, Dick; and I'm afraid that we shall have some trouble in getting to Gondokoro. I am sorry for it; but, at last, we have succeeded in connecting the explorations from the east with those from the north; and we must not complain."

The balloon was now receding gradually from the Nile.

"One last look," said the doctor, "at this impassable latitude, beyond which the most intrepid travellers could not make their way. There are those intractable tribes, of whom Petherick, Arnaud, Miuni, and the young traveller Lejean, to whom we are indebted for the best work on the Upper Nile, have spoken."

"Thus, then," added Kennedy, inquiringly, "our discoveries agree with the speculations of science."

"Absolutely so. The sources of the White Nile, of the Bahr-el-Abiad, are immersed in a lake as large as a sea; it is there that it takes its rise. Poesy, undoubtedly, loses something thereby. People were fond of ascribing a celestial origin to this king of rivers. The ancients gave it the name of an ocean, and were not far from believing that it flowed directly from the sun; but we must come down from these flights from time to time, and accept what science teaches us. There will not always be scientific men, perhaps; but there always will be poets."

"We can still see cataracts," said Joe.

"Those are the cataracts of Makedo, in the third degree of latitude. Nothing could be more accurate. Oh, if we could only have followed the course of the Nile for a few hours!"

"And down yonder, below us, I see the top of a mountain," said the hunter.

"That is Mount Longwek, the Trembling Mountain of the Arabs. This whole country was visited by Debono, who went through it under the name of Latif-Effendi. The tribes living near the Nile are hostile to each other, and are continually waging a war of extermination. You may form some idea, then, of the difficulties he had to encounter."

The wind was carrying the balloon toward the northwest, and, in order to avoid Mount Longwek, it was necessary to seek a more slanting current.

"My friends," said the doctor, "here is where OUR passage of the African Continent really commences; up to this time we have been following the traces of our predecessors. Henceforth we are to launch ourselves upon the unknown. We shall not lack the courage, shall we?"

"Never!" said Dick and Joe together, almost in a shout.

"Onward, then, and may we have the help of Heaven!"

At ten o'clock at night, after passing over ravines, forests, and scattered villages, the aeronauts reached the side of the Trembling Mountain, along whose gentle slopes they went quietly gliding. In that memorable day, the 23d of April, they had, in fifteen hours, impelled by a rapid breeze, traversed a distance of more than three hundred and fifteen miles.

But this latter part of the journey had left them in dull spirits, and complete silence reigned in the car. Was Dr. Ferguson absorbed in the thought of his discoveries? Were his two companions thinking of their trip through those unknown regions? There were, no doubt, mingled with these reflections, the keenest reminiscences of home and distant friends. Joe alone continued to manifest the same careless philosophy, finding it QUITE NATURAL that home should not be there, from the moment that he left it; but he respected the silent mood of his friends, the doctor and Kennedy.

About ten the balloon anchored on the side of the Trembling Mountain, so called, because, in Arab tradition, it is said to tremble the instant that a Mussulman sets foot upon it. The travellers then partook of a substantial meal, and all quietly passed the night as usual, keeping the regular watches.

On awaking the next morning, they all had pleasanter feelings. The weather was fine, and the wind was blowing from the right quarter; so that a good breakfast, seasoned with Joe's merry pranks, put them in high good-humor.

The region they were now crossing is very extensive. It borders on the Mountains of the Moon on one side, and those of Darfur on the other—a space about as broad as Europe.

"We are, no doubt, crossing what is supposed to be the kingdom of Usoga. Geographers have pretended that there existed, in the centre of Africa, a vast depression, an immense central lake. We shall see whether there is any truth in that idea," said the doctor.

"But how did they come to think so?" asked Kennedy.

"From the recitals of the Arabs. Those fellows are great narrators—too much so, probably. Some travellers, who had got as far as Kazeh, or the great lakes, saw slaves that had been brought from this region; interrogated them concerning it, and, from their different narratives, made up a jumble of notions, and deduced systems from them. Down at the bottom of it all there is some appearance of truth; and you see that they were right about the sources of the Nile."

"Nothing could be more correct," said Kennedy. "It was by the aid of these documents that some attempts at maps were made, and so I am going to try to follow our route by one of them, rectifying it when need be."

"Is all this region inhabited?" asked Joe.

"Undoubtedly; and disagreeably inhabited, too."

"I thought so."

"These scattered tribes come, one and all, under the title of Nyam-Nyams, and this compound word is only a sort of nickname. It imitates the sound of chewing."

"That's it! Excellent!" said Joe, champing his teeth as though he were eating; "Nyam-Nyam."

"My good Joe, if you were the immediate object of this chewing, you wouldn't find it so excellent."

"Why, what's the reason, sir?"

"These tribes are considered man-eaters."

"Is that really the case?"

"Not a doubt of it! It has also been asserted that these natives had tails, like mere quadrupeds; but it was soon discovered that these appendages belonged to the skins of animals that they wore for clothing."

"More's the pity! a tail's a nice thing to chase away mosquitoes."

"That may be, Joe; but we must consign the story to the domain of fable, like the dogs' heads which the traveller, Brun-Rollet, attributed to other tribes."

"Dogs' heads, eh? Quite convenient for barking, and even for man-eating!"

"But one thing that has been, unfortunately, proven true, is, the ferocity of these tribes, who are really very fond of human flesh, and devour it with avidity."

"I only hope that they won't take such a particular fancy to mine!" said Joe, with comic solemnity.

"See that!" said Kennedy.

"Yes, indeed, sir; if I have to be eaten, in a moment of famine, I want it to be for your benefit and my master's; but the idea of feeding those black fellows—gracious! I'd die of shame!"

"Well, then, Joe," said Kennedy, "that's understood; we count upon you in case of need!"

"At your service, gentlemen!"

"Joe talks in this way so as to make us take good care of him, and fatten him up."

"Maybe so!" said Joe. "Every man for himself."

In the afternoon, the sky became covered with a warm mist, that oozed from the soil; the brownish vapor scarcely allowed the beholder to distinguish objects, and so, fearing collision with some unexpected mountain-peak, the doctor, about five o'clock, gave the signal to halt.

The night passed without accident, but in such profound obscurity, that it was necessary to use redoubled vigilance.

The monsoon blew with extreme violence during all the next morning. The wind buried itself in the lower cavities of the balloon and shook the appendage by which the dilating-pipes entered the main apparatus. They had, at last, to be tied up with cords, Joe acquitting himself very skilfully in performing that operation.

He had occasion to observe, at the same time, that the orifice of the balloon still remained hermetically sealed.

"That is a matter of double importance for us," said the doctor; "in the first place, we avoid the escape of precious gas, and then, again, we do not leave behind us an inflammable train, which we should at last inevitably set fire to, and so be consumed."

"That would be a disagreeable travelling incident!" said Joe.

"Should we be hurled to the ground?" asked Kennedy.

"Hurled! No, not quite that. The gas would burn quietly, and we should descend little by little. A similar accident happened to a French aeronaut, Madame Blanchard. She ignited her balloon while sending off fireworks, but she did not fall, and she would not have been killed, probably, had not her car dashed against a chimney and precipitated her to the ground."

"Let us hope that nothing of the kind may happen to us," said the hunter. "Up to this time our trip has not seemed to me very dangerous, and I can see nothing to prevent us reaching our destination."

"Nor can I either, my dear Dick; accidents are generally caused by the imprudence of the aeronauts, or the defective construction of their apparatus. However, in thousands of aerial ascensions, there have not been twenty fatal accidents. Usually, the danger is in the moment of leaving the ground, or of alighting, and therefore at those junctures we should never omit the utmost precaution."

"It's breakfast-time," said Joe; "we'll have to put up with preserved meat and coffee until Mr. Kennedy has had another chance to get us a good slice of venison."



CHAPTER TWENTIETH.

The Celestial Bottle.—The Fig-Palms.—The Mammoth Trees.—The Tree of War.—The Winged Team.—Two Native Tribes in Battle.—A Massacre.—An Intervention from above.

The wind had become violent and irregular; the balloon was running the gantlet through the air. Tossed at one moment toward the north, at another toward the south, it could not find one steady current.

"We are moving very swiftly without advancing much," said Kennedy, remarking the frequent oscillations of the needle of the compass.

"The balloon is rushing at the rate of at least thirty miles an hour. Lean over, and see how the country is gliding away beneath us!" said the doctor.

"See! that forest looks as though it were precipitating itself upon us!"

"The forest has become a clearing!" added the other.

"And the clearing a village!" continued Joe, a moment or two later. "Look at the faces of those astonished darkys!"

"Oh! it's natural enough that they should be astonished," said the doctor. "The French peasants, when they first saw a balloon, fired at it, thinking that it was an aerial monster. A Soudan negro may be excused, then, for opening his eyes VERY wide!"

"Faith!" said Joe, as the Victoria skimmed closely along the ground, at scarcely the elevation of one hundred feet, and immediately over a village, "I'll throw them an empty bottle, with your leave, doctor, and if it reaches them safe and sound, they'll worship it; if it breaks, they'll make talismans of the pieces."

So saying, he flung out a bottle, which, of course, was broken into a thousand fragments, while the negroes scampered into their round huts, uttering shrill cries.

A little farther on, Kennedy called out: "Look at that strange tree! The upper part is of one kind and the lower part of another!"

"Well!" said Joe, "here's a country where the trees grow on top of each other."

"It's simply the trunk of a fig-tree," replied the doctor, "on which there is a little vegetating earth. Some fine day, the wind left the seed of a palm on it, and the seed has taken root and grown as though it were on the plain ground."

"A fine new style of gardening," said Joe, "and I'll import the idea to England. It would be just the thing in the London parks; without counting that it would be another way to increase the number of fruit-trees. We could have gardens up in the air; and the small house-owners would like that!"

At this moment, they had to raise the balloon so as to pass over a forest of trees that were more than three hundred feet in height—a kind of ancient banyan.

"What magnificent trees!" exclaimed Kennedy. "I never saw any thing so fine as the appearance of these venerable forests. Look, doctor!"

"The height of these banyans is really remarkable, my dear Dick; and yet, they would be nothing astonishing in the New World."

"Why, are there still loftier trees in existence?"

"Undoubtedly; among the 'mammoth trees' of California, there is a cedar four hundred and eighty feet in height. It would overtop the Houses of Parliament, and even the Great Pyramid of Egypt. The trunk at the surface of the ground was one hundred and twenty feet in circumference, and the concentric layers of the wood disclosed an age of more than four thousand years."

"But then, sir, there was nothing wonderful in it! When one has lived four thousand years, one ought to be pretty tall!" was Joe's remark.

Meanwhile, during the doctor's recital and Joe's response, the forest had given place to a large collection of huts surrounding an open space. In the middle of this grew a solitary tree, and Joe exclaimed, as he caught sight of it:

"Well! if that tree has produced such flowers as those, for the last four thousand years, I have to offer it my compliments, anyhow," and he pointed to a gigantic sycamore, whose whole trunk was covered with human bones. The flowers of which Joe spoke were heads freshly severed from the bodies, and suspended by daggers thrust into the bark of the tree.

"The war-tree of these cannibals!" said the doctor; "the Indians merely carry off the scalp, but these negroes take the whole head."

"A mere matter of fashion!" said Joe. But, already, the village and the bleeding heads were disappearing on the horizon. Another place offered a still more revolting spectacle—half-devoured corpses; skeletons mouldering to dust; human limbs scattered here and there, and left to feed the jackals and hyenas.

"No doubt, these are the bodies of criminals; according to the custom in Abyssinia, these people have left them a prey to the wild beasts, who kill them with their terrible teeth and claws, and then devour them at their leisure.

"Not a whit more cruel than hanging!" said the Scot; "filthier, that's all!"

"In the southern regions of Africa, they content themselves," resumed the doctor, "with shutting up the criminal in his own hut with his cattle, and sometimes with his family. They then set fire to the hut, and the whole party are burned together. I call that cruel; but, like friend Kennedy, I think that the gallows is quite as cruel, quite as barbarous."

Joe, by the aid of his keen sight, which he did not fail to use continually, noticed some flocks of birds of prey flitting about the horizon.

"They are eagles!" exclaimed Kennedy, after reconnoitring them through the glass, "magnificent birds, whose flight is as rapid as ours."

"Heaven preserve us from their attacks!" said the doctor, "they are more to be feared by us than wild beasts or savage tribes."

"Bah!" said the hunter, "we can drive them off with a few rifle-shots."

"Nevertheless, I would prefer, dear Dick, not having to rely upon your skill, this time, for the silk of our balloon could not resist their sharp beaks; fortunately, the huge birds will, I believe, be more frightened than attracted by our machine."

"Yes! but a new idea, and I have dozens of them," said Joe; "if we could only manage to capture a team of live eagles, we could hitch them to the balloon, and they'd haul us through the air!"

"The thing has been seriously proposed," replied the doctor, "but I think it hardly practicable with creatures naturally so restive."

"Oh! we'd tame them," said Joe. "Instead of driving them with bits, we'd do it with eye-blinkers that would cover their eyes. Half blinded in that way, they'd go to the right or to the left, as we desired; when blinded completely, they would stop."

"Allow me, Joe, to prefer a favorable wind to your team of eagles. It costs less for fodder, and is more reliable."

"Well, you may have your choice, master, but I stick to my idea."

It now was noon. The Victoria had been going at a more moderate speed for some time; the country merely passed below it; it no longer flew.

Suddenly, shouts and whistlings were heard by our aeronauts, and, leaning over the edge of the car, they saw on the open plain below them an exciting spectacle.

Two hostile tribes were fighting furiously, and the air was dotted with volleys of arrows. The combatants were so intent upon their murderous work that they did not notice the arrival of the balloon; there were about three hundred mingled confusedly in the deadly struggle: most of them, red with the blood of the wounded, in which they fairly wallowed, were horrible to behold.

As they at last caught sight of the balloon, there was a momentary pause; but their yells redoubled, and some arrows were shot at the Victoria, one of them coming close enough for Joe to catch it with his hand.

"Let us rise out of range," exclaimed the doctor; "there must be no rashness! We are forbidden any risk."

Meanwhile, the massacre continued on both sides, with battle-axes and war-clubs; as quickly as one of the combatants fell, a hostile warrior ran up to cut off his head, while the women, mingling in the fray, gathered up these bloody trophies, and piled them together at either extremity of the battle-field. Often, too, they even fought for these hideous spoils.

"What a frightful scene!" said Kennedy, with profound disgust.

"They're ugly acquaintances!" added Joe; "but then, if they had uniforms they'd be just like the fighters of all the rest of the world!"

"I have a keen hankering to take a hand in at that fight," said the hunter, brandishing his rifle.

"No! no!" objected the doctor, vehemently; "no, let us not meddle with what don't concern us. Do you know which is right or which is wrong, that you would assume the part of the Almighty? Let us, rather, hurry away from this revolting spectacle. Could the great captains of the world float thus above the scenes of their exploits, they would at last, perhaps, conceive a disgust for blood and conquest."

The chieftain of one of the contending parties was remarkable for his athletic proportions, his great height, and herculean strength. With one hand he plunged his spear into the compact ranks of his enemies, and with the other mowed large spaces in them with his battle-axe. Suddenly he flung away his war-club, red with blood, rushed upon a wounded warrior, and, chopping off his arm at a single stroke, carried the dissevered member to his mouth, and bit it again and again.

"Ah!" ejaculated Kennedy, "the horrible brute! I can hold back no longer," and, as he spoke, the huge savage, struck full in the forehead with a rifle-ball, fell headlong to the ground.

Upon this sudden mishap of their leader, his warriors seemed struck dumb with amazement; his supernatural death awed them, while it reanimated the courage and ardor of their adversaries, and, in a twinkling, the field was abandoned by half the combatants.

"Come, let us look higher up for a current to bear us away. I am sick of this spectacle," said the doctor.

But they could not get away so rapidly as to avoid the sight of the victorious tribe rushing upon the dead and the wounded, scrambling and disputing for the still warm and reeking flesh, and eagerly devouring it.

"Faugh!" uttered Joe, "it's sickening."

The balloon rose as it expanded; the howlings of the brutal horde, in the delirium of their orgy, pursued them for a few minutes; but, at length, borne away toward the south, they were carried out of sight and hearing of this horrible spectacle of cannibalism.

The surface of the country was now greatly varied, with numerous streams of water, bearing toward the east. The latter, undoubtedly, ran into those affluents of Lake Nu, or of the River of the Gazelles, concerning which M. Guillaume Lejean has given such curious details.

At nightfall, the balloon cast anchor in twenty-seven degrees east longitude, and four degrees twenty minutes north latitude, after a day's trip of one hundred and fifty miles.
