"But what are we to do? We must get out of this, and the doctor is expecting us."

"Let us decoy the animal. Take my piece, and give me your rifle."

"What is your plan?"

"You'll see."

And Joe, taking off his linen jacket, hung it on the end of the rifle, and thrust it above the top of the steps. The lioness flung herself furiously upon it. Kennedy was on the alert for her, and his bullet broke her shoulder. The lioness, with a frightful howl of agony, rolled down the steps, overturning Joe in her fall. The poor fellow imagined that he could already feel the enormous paws of the savage beast in his flesh, when a second detonation resounded in the narrow passage, and Dr. Ferguson appeared at the opening above with his gun in hand, and still smoking from the discharge.

Joe leaped to his feet, clambered over the body of the dead lioness, and handed up the flask full of sparkling water to his master.

To carry it to his lips, and to half empty it at a draught, was the work of an instant, and the three travellers offered up thanks from the depths of their hearts to that Providence who had so miraculously saved them.



CHAPTER TWENTY-EIGHTH.

An Evening of Delight.—Joe's Culinary Performance.—A Dissertation on Raw Meat.—The Narrative of James Bruce.—Camping out.—Joe's Dreams.—The Barometer begins to fall.—The Barometer rises again.—Preparations for Departure.—The Tempest.

The evening was lovely, and our three friends enjoyed it in the cool shade of the mimosas, after a substantial repast, at which the tea and the punch were dealt out with no niggardly hand.

Kennedy had traversed the little domain in all directions. He had ransacked every thicket and satisfied himself that the balloon party were the only living creatures in this terrestrial paradise; so they stretched themselves upon their blankets and passed a peaceful night that brought them forgetfulness of their past sufferings.

On the morrow, May 7th, the sun shone with all his splendor, but his rays could not penetrate the dense screen of the palm-tree foliage, and as there was no lack of provisions, the doctor resolved to remain where he was while waiting for a favorable wind.

Joe had conveyed his portable kitchen to the oasis, and proceeded to indulge in any number of culinary combinations, using water all the time with the most profuse extravagance.

"What a strange succession of annoyances and enjoyments!" moralized Kennedy. "Such abundance as this after such privations; such luxury after such want! Ah! I nearly went mad!"

"My dear Dick," replied the doctor, "had it not been for Joe, you would not be sitting here, to-day, discoursing on the instability of human affairs."

"Whole-hearted friend!" said Kennedy, extending his hand to Joe.

"There's no occasion for all that," responded the latter; "but you can take your revenge some time, Mr. Kennedy, always hoping though that you may never have occasion to do the same for me!"

"It's a poor constitution this of ours to succumb to so little," philosophized Dr. Ferguson.

"So little water, you mean, doctor," interposed Joe; "that element must be very necessary to life."

"Undoubtedly, and persons deprived of food hold out longer than those deprived of water."

"I believe it. Besides, when needs must, one can eat any thing he comes across, even his fellow-creatures, although that must be a kind of food that's pretty hard to digest."

"The savages don't boggle much about it!" said Kennedy.

"Yes; but then they are savages, and accustomed to devouring raw meat; it's something that I'd find very disgusting, for my part."

"It is disgusting enough," said the doctor, "that's a fact; and so much so, indeed, that nobody believed the narratives of the earliest travellers in Africa who brought back word that many tribes on that continent subsisted upon raw meat, and people generally refused to credit the statement. It was under such circumstances that a very singular adventure befell James Bruce."

"Tell it to us, doctor; we've time enough to hear it," said Joe, stretching himself voluptuously on the cool greensward.

"By all means.—James Bruce was a Scotchman, of Stirlingshire, who, between 1768 and 1772, traversed all Abyssinia, as far as Lake Tyana, in search of the sources of the Nile. He afterward returned to England, but did not publish an account of his journeys until 1790. His statements were received with extreme incredulity, and such may be the reception accorded to our own. The manners and customs of the Abyssinians seemed so different from those of the English, that no one would credit the description of them. Among other details, Bruce had put forward the assertion that the tribes of Eastern Africa fed upon raw flesh, and this set everybody against him. He might say so as much as he pleased; there was no one likely to go and see! One day, in a parlor at Edinburgh, a Scotch gentleman took up the subject in his presence, as it had become the topic of daily pleasantry, and, in reference to the eating of raw flesh, said that the thing was neither possible nor true. Bruce made no reply, but went out and returned a few minutes later with a raw steak, seasoned with pepper and salt, in the African style.

"'Sir,' said he to the Scotchman, 'in doubting my statements, you have grossly affronted me; in believing the thing to be impossible, you have been egregiously mistaken; and, in proof thereof, you will now eat this beef-steak raw, or you will give me instant satisfaction!' The Scotchman had a wholesome dread of the brawny traveller, and DID eat the steak, although not without a good many wry faces. Thereupon, with the utmost coolness, James Bruce added: 'Even admitting, sir, that the thing were untrue, you will, at least, no longer maintain that it is impossible.'"

"Well put in!" said Joe, "and if the Scotchman found it lie heavy on his stomach, he got no more than he deserved. If, on our return to England, they dare to doubt what we say about our travels—"

"Well, Joe, what would you do?"

"Why, I'll make the doubters swallow the pieces of the balloon, without either salt or pepper!"

All burst out laughing at Joe's queer notions, and thus the day slipped by in pleasant chat. With returning strength, hope had revived, and with hope came the courage to do and to dare. The past was obliterated in the presence of the future with providential rapidity.

Joe would have been willing to remain forever in this enchanting asylum; it was the realm he had pictured in his dreams; he felt himself at home; his master had to give him his exact location, and it was with the gravest air imaginable that he wrote down on his tablets fifteen degrees forty-three minutes east longitude, and eight degrees thirty-two minutes north latitude.

Kennedy had but one regret, to wit, that he could not hunt in that miniature forest, because, according to his ideas, there was a slight deficiency of ferocious wild beasts in it.

"But, my dear Dick," said the doctor, "haven't you rather a short memory? How about the lion and the lioness?"

"Oh, that!" he ejaculated with the contempt of a thorough-bred sportsman for game already killed. "But the fact is, that finding them here would lead one to suppose that we can't be far from a more fertile country."

"It don't prove much, Dick, for those animals, when goaded by hunger or thirst, will travel long distances, and I think that, to-night, we had better keep a more vigilant lookout, and light fires, besides."

"What, in such heat as this?" said Joe. "Well, if it's necessary, we'll have to do it, but I do think it a real pity to burn this pretty grove that has been such a comfort to us!"

"Oh! above all things, we must take the utmost care not to set it on fire," replied the doctor, "so that others in the same strait as ourselves may some day find shelter here in the middle of the desert."

"I'll be very careful, indeed, doctor; but do you think that this oasis is known?"

"Undoubtedly; it is a halting-place for the caravans that frequent the centre of Africa, and a visit from one of them might be any thing but pleasant to you, Joe."

"Why, are there any more of those rascally Nyam-Nyams around here?"

"Certainly; that is the general name of all the neighboring tribes, and, under the same climates, the same races are likely to have similar manners and customs."

"Pah!" said Joe, "but, after all, it's natural enough. If savages had the ways of gentlemen, where would be the difference? By George, these fine fellows wouldn't have to be coaxed long to eat the Scotchman's raw steak, nor the Scotchman either, into the bargain!"

With this very sensible observation, Joe began to get ready his firewood for the night, making just as little of it as possible. Fortunately, these precautions were superfluous; and each of the party, in his turn, dropped off into the soundest slumber.

On the next day the weather still showed no sign of change, but kept provokingly and obstinately fair. The balloon remained motionless, without any oscillation to betray a breath of wind.

The doctor began to get uneasy again. If their stay in the desert were to be prolonged like this, their provisions would give out. After nearly perishing for want of water, they would, at last, have to starve to death!

But he took fresh courage as he saw the mercury fall considerably in the barometer, and noticed evident signs of an early change in the atmosphere. He therefore resolved to make all his preparations for a start, so as to avail himself of the first opportunity. The feeding-tank and the water-tank were both completely filled.

Then he had to reestablish the equilibrium of the balloon, and Joe was obliged to part with another considerable portion of his precious quartz. With restored health, his ambitious notions had come back to him, and he made more than one wry face before obeying his master; but the latter convinced him that he could not carry so considerable a weight with him through the air, and gave him his choice between the water and the gold. Joe hesitated no longer, but flung out the requisite quantity of his much-prized ore upon the sand.

"The next people who come this way," he remarked, "will be rather surprised to find a fortune in such a place."

"And suppose some learned traveller should come across these specimens, eh?" suggested Kennedy.

"You may be certain, Dick, that they would take him by surprise, and that he would publish his astonishment in several folios; so that some day we shall hear of a wonderful deposit of gold-bearing quartz in the midst of the African sands!"

"And Joe there, will be the cause of it all!"

This idea of mystifying some learned sage tickled Joe hugely, and made him laugh.

During the rest of the day the doctor vainly kept on the watch for a change of weather. The temperature rose, and, had it not been for the shade of the oasis, would have been insupportable. The thermometer marked a hundred and forty-nine degrees in the sun, and a veritable rain of fire filled the air. This was the most intense heat that they had yet noted.

Joe arranged their bivouac for that evening, as he had done for the previous night; and during the watches kept by the doctor and Kennedy there was no fresh incident.

But, toward three o'clock in the morning, while Joe was on guard, the temperature suddenly fell; the sky became overcast with clouds, and the darkness increased.

"Turn out!" cried Joe, arousing his companions. "Turn out! Here's the wind!"

"At last!" exclaimed the doctor, eying the heavens. "But it is a storm! The balloon! Let us hasten to the balloon!"

It was high time for them to reach it. The Victoria was bending to the force of the hurricane, and dragging along the car, the latter grazing the sand. Had any portion of the ballast been accidentally thrown out, the balloon would have been swept away, and all hope of recovering it have been forever lost.

But fleet-footed Joe put forth his utmost speed, and checked the car, while the balloon beat upon the sand, at the risk of being torn to pieces. The doctor, followed by Kennedy, leaped in, and lit his cylinder, while his companions threw out the superfluous ballast.

The travellers took one last look at the trees of the oasis bowing to the force of the hurricane, and soon, catching the wind at two hundred feet above the ground, disappeared in the gloom.



CHAPTER TWENTY-NINTH.

Signs of Vegetation.—The Fantastic Notion of a French Author.—A Magnificent Country.—The Kingdom of Adamova.—The Explorations of Speke and Burton connected with those of Dr. Barth.—The Atlantika Mountains.—The River Benoue.—The City of Yola.—The Bagele.—Mount Mendif.

From the moment of their departure, the travellers moved with great velocity. They longed to leave behind them the desert, which had so nearly been fatal to them.

About a quarter-past nine in the morning, they caught a glimpse of some signs of vegetation: herbage floating on that sea of sand, and announcing, as the weeds upon the ocean did to Christopher Columbus, the nearness of the shore—green shoots peeping up timidly between pebbles that were, in their turn, to be the rocks of that vast expanse.

Hills, but of trifling height, were seen in wavy lines upon the horizon. Their profile, muffled by the heavy mist, was defined but vaguely. The monotony, however, was beginning to disappear.

The doctor hailed with joy the new country thus disclosed, and, like a seaman on lookout at the mast-head, he was ready to shout aloud:

"Land, ho! land!"

An hour later the continent spread broadly before their gaze, still wild in aspect, but less flat, less denuded, and with a few trees standing out against the gray sky.

"We are in a civilized country at last!" said the hunter.

"Civilized? Well, that's one way of speaking; but there are no people to be seen yet."

"It will not be long before we see them," said Ferguson, "at our present rate of travel."

"Are we still in the negro country, doctor?"

"Yes, and on our way to the country of the Arabs."

"What! real Arabs, sir, with their camels?"

"No, not many camels; they are scarce, if not altogether unknown, in these regions. We must go a few degrees farther north to see them."

"What a pity!"

"And why, Joe?"

"Because, if the wind fell contrary, they might be of use to us."

"How so?"

"Well, sir, it's just a notion that's got into my head: we might hitch them to the car, and make them tow us along. What do you say to that, doctor?"

"Poor Joe! Another person had that idea in advance of you. It was used by a very gifted French author— M. Mery—in a romance, it is true. He has his travellers drawn along in a balloon by a team of camels; then a lion comes up, devours the camels, swallows the tow-rope, and hauls the balloon in their stead; and so on through the story. You see that the whole thing is the top-flower of fancy, but has nothing in common with our style of locomotion."

Joe, a little cut down at learning that his idea had been used already, cudgelled his wits to imagine what animal could have devoured the lion; but he could not guess it, and so quietly went on scanning the appearance of the country.

A lake of medium extent stretched away before him, surrounded by an amphitheatre of hills, which yet could not be dignified with the name of mountains. There were winding valleys, numerous and fertile, with their tangled thickets of the most various trees. The African oil-tree rose above the mass, with leaves fifteen feet in length upon its stalk, the latter studded with sharp thorns; the bombax, or silk-cotton-tree, filled the wind, as it swept by, with the fine down of its seeds; the pungent odors of the pendanus, the "kenda" of the Arabs, perfumed the air up to the height where the Victoria was sailing; the papaw-tree, with its palm-shaped leaves; the sterculier, which produces the Soudan-nut; the baobab, and the banana-tree, completed the luxuriant flora of these inter-tropical regions.

"The country is superb!" said the doctor.

"Here are some animals," added Joe. "Men are not far away."

"Oh, what magnificent elephants!" exclaimed Kennedy. "Is there no way to get a little shooting?"

"How could we manage to halt in a current as strong as this? No, Dick; you must taste a little of the torture of Tantalus just now. You shall make up for it afterward."

And, in truth, there was enough to excite the fancy of a sportsman. Dick's heart fairly leaped in his breast as he grasped the butt of his Purdy.

The fauna of the region were as striking as its flora. The wild-ox revelled in dense herbage that often concealed his whole body; gray, black, and yellow elephants of the most gigantic size burst headlong, like a living hurricane, through the forests, breaking, rending, tearing down, devastating every thing in their path; upon the woody slopes of the hills trickled cascades and springs flowing northward; there, too, the hippopotami bathed their huge forms, splashing and snorting as they frolicked in the water, and lamantines, twelve feet long, with bodies like seals, stretched themselves along the banks, turning up toward the sun their rounded teats swollen with milk.

It was a whole menagerie of rare and curious beasts in a wondrous hot-house, where numberless birds with plumage of a thousand hues gleamed and fluttered in the sunshine.

By this prodigality of Nature, the doctor recognized the splendid kingdom of Adamova.

"We are now beginning to trench upon the realm of modern discovery. I have taken up the lost scent of preceding travellers. It is a happy chance, my friends, for we shall be enabled to link the toils of Captains Burton and Speke with the explorations of Dr. Barth. We have left the Englishmen behind us, and now have caught up with the Hamburger. It will not be long, either, before we arrive at the extreme point attained by that daring explorer."

"It seems to me that there is a vast extent of country between the two explored routes," remarked Kennedy; "at least, if I am to judge by the distance that we have made."

"It is easy to determine: take the map and see what is the longitude of the southern point of Lake Ukereoue, reached by Speke."

"It is near the thirty-seventh degree."

"And the city of Yola, which we shall sight this evening, and to which Barth penetrated, what is its position?"

"It is about in the twelfth degree of east longitude."

"Then there are twenty-five degrees, or, counting sixty miles to each, about fifteen hundred miles in all."

"A nice little walk," said Joe, "for people who have to go on foot."

"It will be accomplished, however. Livingstone and Moffat are pushing on up this line toward the interior. Nyassa, which they have discovered, is not far from Lake Tanganayika, seen by Burton. Ere the close of the century these regions will, undoubtedly, be explored. But," added the doctor, consulting his compass, "I regret that the wind is carrying us so far to the westward. I wanted to get to the north."

After twelve hours of progress, the Victoria found herself on the confines of Nigritia. The first inhabitants of this region, the Chouas Arabs, were feeding their wandering flocks. The immense summits of the Atlantika Mountains seen above the horizon—mountains that no European foot had yet scaled, and whose height is computed to be ten thousand feet! Their western slope determines the flow of all the waters in this region of Africa toward the ocean. They are the Mountains of the Moon to this part of the continent.

At length a real river greeted the gaze of our travellers, and, by the enormous ant-hills seen in its vicinity, the doctor recognized the Benoue, one of the great tributaries of the Niger, the one which the natives have called "The Fountain of the Waters."

"This river," said the doctor to his companions, "will, one day, be the natural channel of communication with the interior of Nigritia. Under the command of one of our brave captains, the steamer Pleiad has already ascended as far as the town of Yola. You see that we are not in an unknown country."

Numerous slaves were engaged in the labors of the field, cultivating sorgho, a kind of millet which forms the chief basis of their diet; and the most stupid expressions of astonishment ensued as the Victoria sped past like a meteor. That evening the balloon halted about forty miles from Yola, and ahead of it, but in the distance, rose the two sharp cones of Mount Mendif.

The doctor threw out his anchors and made fast to the top of a high tree; but a very violent wind beat upon the balloon with such force as to throw it over on its side, thus rendering the position of the car sometimes extremely dangerous. Ferguson did not close his all night, and he was repeatedly on the point of cutting the anchor-rope and scudding away before the gale. At length, however, the storm abated, and the oscillations of the balloon ceased to be alarming.

On the morrow the wind was more moderate, but it carried our travellers away from the city of Yola, which recently rebuilt by the Fouillans, excited Ferguson's curiosity. However, he had to make up his mind to being borne farther to the northward and even a little to the east.

Kennedy proposed to halt in this fine hunting-country, and Joe declared that the need of fresh meat was beginning to be felt; but the savage customs of the country, the attitude of the population, and some shots fired at the Victoria, admonished the doctor to continue his journey. They were then crossing a region that was the scene of massacres and burnings, and where warlike conflicts between the barbarian sultans, contending for their power amid the most atrocious carnage, never cease.

Numerous and populous villages of long low huts stretched away between broad pasture-fields whose dense herbage was besprinkled with violet-colored blossoms. The huts, looking like huge beehives, were sheltered behind bristling palisades. The wild hill-sides and hollows frequently reminded the beholder of the glens in the Highlands of Scotland, as Kennedy more than once remarked.

In spite of all he could do, the doctor bore directly to the northeast, toward Mount Mendif, which was lost in the midst of environing clouds. The lofty summits of these mountains separate the valley of the Niger from the basin of Lake Tchad.

Soon afterward was seen the Bagele, with its eighteen villages clinging to its flanks like a whole brood of children to their mother's bosom—a magnificent spectacle for the beholder whose gaze commanded and took in the entire picture at one view. Even the ravines were seen to be covered with fields of rice and of arachides.

By three o'clock the Victoria was directly in front of Mount Mendif. It had been impossible to avoid it; the only thing to be done was to cross it. The doctor, by means of a temperature increased to one hundred and eighty degrees, gave the balloon a fresh ascensional force of nearly sixteen hundred pounds, and it went up to an elevation of more than eight thousand feet, the greatest height attained during the journey. The temperature of the atmosphere was so much cooler at that point that the aeronauts had to resort to their blankets and thick coverings.

Ferguson was in haste to descend; the covering of the balloon gave indications of bursting, but in the meanwhile he had time to satisfy himself of the volcanic origin of the mountain, whose extinct craters are now but deep abysses. Immense accumulations of bird-guano gave the sides of Mount Mendif the appearance of calcareous rocks, and there was enough of the deposit there to manure all the lands in the United Kingdom.

At five o'clock the Victoria, sheltered from the south winds, went gently gliding along the slopes of the mountain, and stopped in a wide clearing remote from any habitation. The instant it touched the soil, all needful precautions were taken to hold it there firmly; and Kennedy, fowling-piece in hand, sallied out upon the sloping plain. Ere long, he returned with half a dozen wild ducks and a kind of snipe, which Joe served up in his best style. The meal was heartily relished, and the night was passed in undisturbed and refreshing slumber.



CHAPTER THIRTIETH.

Mosfeia.—The Sheik.—Denham, Clapperton, and Oudney.—Vogel.—The Capital of Loggoum.—Toole.—Becalmed above Kernak.—The Governor and his Court. —The Attack.—The Incendiary Pigeons.

On the next day, May 11th, the Victoria resumed her adventurous journey. Her passengers had the same confidence in her that a good seaman has in his ship.

In terrific hurricanes, in tropical heats, when making dangerous departures, and descents still more dangerous, it had, at all times and in all places, come out safely. It might almost have been said that Ferguson managed it with a wave of the hand; and hence, without knowing in advance, where the point of arrival would be, the doctor had no fears concerning the successful issue of his journey. However, in this country of barbarians and fanatics, prudence obliged him to take the strictest precautions. He therefore counselled his companions to have their eyes wide open for every thing and at all hours.

The wind drifted a little more to the northward, and, toward nine o'clock, they sighted the larger city of Mosfeia, built upon an eminence which was itself enclosed between two lofty mountains. Its position was impregnable, a narrow road running between a marsh and a thick wood being the only channel of approach to it.

At the moment of which we write, a sheik, accompanied by a mounted escort, and clad in a garb of brilliant colors, preceded by couriers and trumpeters, who put aside the boughs of the trees as he rode up, was making his grand entry into the place.

The doctor lowered the balloon in order to get a better look at this cavalcade of natives; but, as the balloon grew larger to their eyes, they began to show symptoms of intense affright, and at length made off in different directions as fast as their legs and those of their horses could carry them.

The sheik alone did not budge an inch. He merely grasped his long musket, cocked it, and proudly waited in silence. The doctor came on to within a hundred and fifty feet of him, and then, with his roundest and fullest voice, saluted him courteously in the Arabic tongue.

But, upon hearing these words falling, as it seemed, from the sky, the sheik dismounted and prostrated himself in the dust of the highway, where the doctor had to leave him, finding it impossible to divert him from his adoration.

"Unquestionably," Ferguson remarked, "those people take us for supernatural beings. When Europeans came among them for the first time, they were mistaken for creatures of a higher race. When this sheik comes to speak of to-day's meeting, he will not fail to embellish the circumstance with all the resources of an Arab imagination. You may, therefore, judge what an account their legends will give of us some day."

"Not such a desirable thing, after all," said the Scot, "in the point of view that affects civilization; it would be better to pass for mere men. That would give these negro races a superior idea of European power."

"Very good, my dear Dick; but what can we do about it? You might sit all day explaining the mechanism of a balloon to the savants of this country, and yet they would not comprehend you, but would persist in ascribing it to supernatural aid."

"Doctor, you spoke of the first time Europeans visited these regions. Who were the visitors?" inquired Joe.

"My dear fellow, we are now upon the very track of Major Denham. It was at this very city of Mosfeia that he was received by the Sultan of Mandara; he had quitted the Bornou country; he accompanied the sheik in an expedition against the Fellatahs; he assisted in the attack on the city, which, with its arrows alone, bravely resisted the bullets of the Arabs, and put the sheik's troops to flight. All this was but a pretext for murders, raids, and pillage. The major was completely plundered and stripped, and had it not been for his horse, under whose stomach he clung with the skill of an Indian rider, and was borne with a headlong gallop from his barbarous pursuers, he never could have made his way back to Kouka, the capital of Bornou."

"Who was this Major Denham?"

"A fearless Englishman, who, between 1822 and 1824, commanded an expedition into the Bornou country, in company with Captain Clapperton and Dr. Oudney. They set out from Tripoli in the month of March, reached Mourzouk, the capital of Fez, and, following the route which at a later period Dr. Barth was to pursue on his way back to Europe, they arrived, on the 16th of February, 1823, at Kouka, near Lake Tchad. Denham made several explorations in Bornou, in Mandara, and to the eastern shores of the lake. In the mean time, on the 15th of December, 1823, Captain Clapperton and Dr. Oudney had pushed their way through the Soudan country as far as Sackatoo, and Oudney died of fatigue and exhaustion in the town of Murmur."

"This part of Africa has, therefore, paid a heavy tribute of victims to the cause of science," said Kennedy.

"Yes, this country is fatal to travellers. We are moving directly toward the kingdom of Baghirmi, which Vogel traversed in 1856, so as to reach the Wadai country, where he disappeared. This young man, at the age of twenty-three, had been sent to cooperate with Dr. Barth. They met on the 1st of December, 1854, and thereupon commenced his explorations of the country. Toward 1856, he announced, in the last letters received from him, his intention to reconnoitre the kingdom of Wadai, which no European had yet penetrated. It appears that he got as far as Wara, the capital, where, according to some accounts, he was made prisoner, and, according to others, was put to death for having attempted to ascend a sacred mountain in the environs. But, we must not too lightly admit the death of travellers, since that does away with the necessity of going in search of them. For instance, how often was the death of Dr. Barth reported, to his own great annoyance! It is, therefore, very possible that Vogel may still be held as a prisoner by the Sultan of Wadai, in the hope of obtaining a good ransom for him.

"Baron de Neimans was about starting for the Wadai country when he died at Cairo, in 1855; and we now know that De Heuglin has set out on Vogel's track with the expedition sent from Leipsic, so that we shall soon be accurately informed as to the fate of that young and interesting explorer."*

* Since the doctor's departure, letters written from El'Obeid by Mr. Muntzinger, the newly-appointed head of the expedition, unfortunately place the death of Vogel beyond a doubt.

Mosfeia had disappeared from the horizon long ere this, and the Mandara country was developing to the gaze of our aeronauts its astonishing fertility, with its forests of acacias, its locust-trees covered with red flowers, and the herbaceous plants of its fields of cotton and indigo trees. The river Shari, which eighty miles farther on rolled its impetuous waters into Lake Tchad, was quite distinctly seen.

The doctor got his companions to trace its course upon the maps drawn by Dr. Barth.

"You perceive," said he, "that the labors of this savant have been conducted with great precision; we are moving directly toward the Loggoum region, and perhaps toward Kernak, its capital. It was there that poor Toole died, at the age of scarcely twenty-two. He was a young Englishman, an ensign in the 80th regiment, who, a few weeks before, had joined Major Denham in Africa, and it was not long ere he there met his death. Ah! this vast country might well be called the graveyard of European travellers."

Some boats, fifty feet long, were descending the current of the Shari. The Victoria, then one thousand feet above the soil, hardly attracted the attention of the natives; but the wind, which until then had been blowing with a certain degree of strength, was falling off.

"Is it possible that we are to be caught in another dead calm?" sighed the doctor.

"Well, we've no lack of water, nor the desert to fear, anyhow, master," said Joe.

"No; but there are races here still more to be dreaded."

"Why!" said Joe, again, "there's something like a town."

"That is Kernak. The last puffs of the breeze are wafting us to it, and, if we choose, we can take an exact plan of the place."

"Shall we not go nearer to it?" asked Kennedy.

"Nothing easier, Dick! We are right over it. Allow me to turn the stopcock of the cylinder, and we'll not be long in descending."

Half an hour later the balloon hung motionless about two hundred feet from the ground.

"Here we are!" said the doctor, "nearer to Kernak than a man would be to London, if he were perched in the cupola of St. Paul's. So we can take a survey at our ease."

"What is that tick-tacking sound that we hear on all sides?"

Joe looked attentively, and at length discovered that the noise they heard was produced by a number of weavers beating cloth stretched in the open air, on large trunks of trees.

The capital of Loggoum could then be seen in its entire extent, like an unrolled chart. It is really a city with straight rows of houses and quite wide streets. In the midst of a large open space there was a slave-market, attended by a great crowd of customers, for the Mandara women, who have extremely small hands and feet, are in excellent request, and can be sold at lucrative rates.

At the sight of the Victoria, the scene so often produced occurred again. At first there were outcries, and then followed general stupefaction; business was abandoned; work was flung aside, and all noise ceased. The aeronauts remained as they were, completely motionless, and lost not a detail of the populous city. They even went down to within sixty feet of the ground.

Hereupon the Governor of Loggoum came out from his residence, displaying his green standard, and accompanied by his musicians, who blew on hoarse buffalo-horns, as though they would split their cheeks or any thing else, excepting their own lungs. The crowd at once gathered around him. In the mean while Dr. Ferguson tried to make himself heard, but in vain.

This population looked like proud and intelligent people, with their high foreheads, their almost aquiline noses, and their curling hair; but the presence of the Victoria troubled them greatly. Horsemen could be seen galloping in all directions, and it soon became evident that the governor's troops were assembling to oppose so extraordinary a foe. Joe wore himself out waving handkerchiefs of every color and shape to them; but his exertions were all to no purpose.

However, the sheik, surrounded by his court, proclaimed silence, and pronounced a discourse, of which the doctor could not understand a word. It was Arabic, mixed with Baghirmi. He could make out enough, however, by the universal language of gestures, to be aware that he was receiving a very polite invitation to depart. Indeed, he would have asked for nothing better, but for lack of wind, the thing had become impossible. His noncompliance, therefore, exasperated the governor, whose courtiers and attendants set up a furious howl to enforce immediate obedience on the part of the aerial monster.

They were odd-looking fellows those courtiers, with their five or six shirts swathed around their bodies! They had enormous stomachs, some of which actually seemed to be artificial. The doctor surprised his companions by informing them that this was the way to pay court to the sultan. The rotundity of the stomach indicated the ambition of its possessor. These corpulent gentry gesticulated and bawled at the top of their voices—one of them particularly distinguishing himself above the rest—to such an extent, indeed, that he must have been a prime minister—at least, if the disturbance he made was any criterion of his rank. The common rabble of dusky denizens united their howlings with the uproar of the court, repeating their gesticulations like so many monkeys, and thereby producing a single and instantaneous movement of ten thousand arms at one time.

To these means of intimidation, which were presently deemed insufficient, were added others still more formidable. Soldiers, armed with bows and arrows, were drawn up in line of battle; but by this time the balloon was expanding, and rising quietly beyond their reach. Upon this the governor seized a musket and aimed it at the balloon; but, Kennedy, who was watching him, shattered the uplifted weapon in the sheik's grasp.

At this unexpected blow there was a general rout. Every mother's son of them scampered for his dwelling with the utmost celerity, and stayed there, so that the streets of the town were absolutely deserted for the remainder of that day.

Night came, and not a breath of wind was stirring. The aeronauts had to make up their minds to remain motionless at the distance of but three hundred feet above the ground. Not a fire or light shone in the deep gloom, and around reigned the silence of death; but the doctor only redoubled his vigilance, as this apparent quiet might conceal some snare.

And he had reason to be watchful. About midnight, the whole city seemed to be in a blaze. Hundreds of streaks of flame crossed each other, and shot to and fro in the air like rockets, forming a regular network of fire.

"That's really curious!" said the doctor, somewhat puzzled to make out what it meant.

"By all that's glorious!" shouted Kennedy, "it looks as if the fire were ascending and coming up toward us!"

And, sure enough, with an accompaniment of musket-shots, yelling, and din of every description, the mass of fire was, indeed, mounting toward the Victoria. Joe got ready to throw out ballast, and Ferguson was not long at guessing the truth. Thousands of pigeons, their tails garnished with combustibles, had been set loose and driven toward the Victoria; and now, in their terror, they were flying high up, zigzagging the atmosphere with lines of fire. Kennedy was preparing to discharge all his batteries into the middle of the ascending multitude, but what could he have done against such a numberless army? The pigeons were already whisking around the car; they were even surrounding the balloon, the sides of which, reflecting their illumination, looked as though enveloped with a network of fire.

The doctor dared hesitate no longer; and, throwing out a fragment of quartz, he kept himself beyond the reach of these dangerous assailants; and, for two hours afterward, he could see them wandering hither and thither through the darkness of the night, until, little by little, their light diminished, and they, one by one, died out.

"Now we may sleep in quiet," said the doctor.

"Not badly got up for barbarians," mused friend Joe, speaking his thoughts aloud.

"Oh, they employ these pigeons frequently, to set fire to the thatch of hostile villages; but this time the village mounted higher than they could go."

"Why, positively, a balloon need fear no enemies!"

"Yes, indeed, it may!" objected Ferguson.

"What are they, then, doctor?"

"They are the careless people in the car! So, my friends, let us have vigilance in all places and at all times."



CHAPTER THIRTY-FIRST.

Departure in the Night-time.—All Three.—Kennedy's Instincts.—Precautions.— The Course of the Shari River.—Lake Tchad.—The Water of the Lake.—The Hippopotamus.—One Bullet thrown away.

About three o'clock in the morning, Joe, who was then on watch, at length saw the city move away from beneath his feet. The Victoria was once again in motion, and both the doctor and Kennedy awoke.

The former consulted his compass, and saw, with satisfaction, that the wind was carrying them toward the north-northeast.

"We are in luck!" said he; "every thing works in our favor: we shall discover Lake Tchad this very day."

"Is it a broad sheet of water?" asked Kennedy.

"Somewhat, Dick. At its greatest length and breadth, it measures about one hundred and twenty miles."

"It will spice our trip with a little variety to sail over a spacious sheet of water."

"After all, though, I don't see that we have much to complain of on that score. Our trip has been very much varied, indeed; and, moreover, we are getting on under the best possible conditions."

"Unquestionably so; excepting those privations on the desert, we have encountered no serious danger."

"It is not to be denied that our noble balloon has behaved wonderfully well. To-day is May 12th, and we started on the 18th of April. That makes twenty-five days of journeying. In ten days more we shall have reached our destination."

"Where is that?"

"I do not know. But what does that signify?"

"You are right again, Samuel! Let us intrust to Providence the care of guiding us and of keeping us in good health as we are now. We don't look much as though we had been crossing the most pestilential country in the world!"

"We had an opportunity of getting up in life, and that's what we have done!"

"Hurrah for trips in the air!" cried Joe. "Here we are at the end of twenty-five days in good condition, well fed, and well rested. We've had too much rest in fact, for my legs begin to feel rusty, and I wouldn't be vexed a bit to stretch them with a run of thirty miles or so!"

"You can do that, Joe, in the streets of London, but in fine we set out three together, like Denham, Clapperton, and Overweg; like Barth, Richardson, and Vogel, and, more fortunate than our predecessors here, we are three in number still. But it is most important for us not to separate. If, while one of us was on the ground, the Victoria should have to ascend in order to escape some sudden danger, who knows whether we should ever see each other again? Therefore it is that I say again to Kennedy frankly that I do not like his going off alone to hunt."

"But still, Samuel, you will permit me to indulge that fancy a little. There is no harm in renewing our stock of provisions. Besides, before our departure, you held out to me the prospect of some superb hunting, and thus far I have done but little in the line of the Andersons and Cummings."

"But, my dear Dick, your memory fails you, or your modesty makes you forget your own exploits. It really seems to me that, without mentioning small game, you have already an antelope, an elephant, and two lions on your conscience."

"But what's all that to an African sportsman who sees all the animals in creation strutting along under the muzzle of his rifle? There! there! look at that troop of giraffes!"

"Those giraffes," roared Joe; "why, they're not as big as my fist."

"Because we are a thousand feet above them; but close to them you would discover that they are three times as tall as you are!"

"And what do you say to yon herd of gazelles, and those ostriches, that run with the speed of the wind?" resumed Kennedy.

"Those ostriches?" remonstrated Joe, again; "those are chickens, and the greatest kind of chickens!"

"Come, doctor, can't we get down nearer to them?" pleaded Kennedy.

"We can get closer to them, Dick, but we must not land. And what good will it do you to strike down those poor animals when they can be of no use to you? Now, if the question were to destroy a lion, a tiger, a cat, a hyena, I could understand it; but to deprive an antelope or a gazelle of life, to no other purpose than the gratification of your instincts as a sportsman, seems hardly worth the trouble. But, after all, my friend, we are going to keep at about one hundred feet only from the soil, and, should you see any ferocious wild beast, oblige us by sending a ball through its heart!"

The Victoria descended gradually, but still keeping at a safe height, for, in a barbarous, yet very populous country, it was necessary to keep on the watch for unexpected perils.

The travellers were then directly following the course of the Shari. The charming banks of this river were hidden beneath the foliage of trees of various dyes; lianas and climbing plants wound in and out on all sides and formed the most curious combinations of color. Crocodiles were seen basking in the broad blaze of the sun or plunging beneath the waters with the agility of lizards, and in their gambols they sported about among the many green islands that intercept the current of the stream.

It was thus, in the midst of rich and verdant landscapes that our travellers passed over the district of Maffatay, and about nine o'clock in the morning reached the southern shore of Lake Tchad.

There it was at last, outstretched before them, that Caspian Sea of Africa, the existence of which was so long consigned to the realms of fable—that interior expanse of water to which only Denham's and Barth's expeditions had been able to force their way.

The doctor strove in vain to fix its precise configuration upon paper. It had already changed greatly since 1847. In fact, the chart of Lake Tchad is very difficult to trace with exactitude, for it is surrounded by muddy and almost impassable morasses, in which Barth thought that he was doomed to perish. From year to year these marshes, covered with reeds and papyrus fifteen feet high, become the lake itself. Frequently, too, the villages on its shores are half submerged, as was the case with Ngornou in 1856, and now the hippopotamus and the alligator frisk and dive where the dwellings of Bornou once stood.

The sun shot his dazzling rays over this placid sheet of water, and toward the north the two elements merged into one and the same horizon.

The doctor was desirous of determining the character of the water, which was long believed to be salt. There was no danger in descending close to the lake, and the car was soon skimming its surface like a bird at the distance of only five feet.

Joe plunged a bottle into the lake and drew it up half filled. The water was then tasted and found to be but little fit for drinking, with a certain carbonate-of-soda flavor.

While the doctor was jotting down the result of this experiment, the loud report of a gun was heard close beside him. Kennedy had not been able to resist the temptation of firing at a huge hippopotamus. The latter, who had been basking quietly, disappeared at the sound of the explosion, but did not seem to be otherwise incommoded by Kennedy's conical bullet.

"You'd have done better if you had harpooned him," said Joe.

"But how?"

"With one of our anchors. It would have been a hook just big enough for such a rousing beast as that!"

"Humph!" ejaculated Kennedy, "Joe really has an idea this time—"

"Which I beg of you not to put into execution," interposed the doctor. "The animal would very quickly have dragged us where we could not have done much to help ourselves, and where we have no business to be."

"Especially now since we've settled the question as to what kind of water there is in Lake Tchad. Is that sort of fish good to eat, Dr. Ferguson?"

"That fish, as you call it, Joe, is really a mammiferous animal of the pachydermal species. Its flesh is said to be excellent and is an article of important trade between the tribes living along the borders of the lake."

"Then I'm sorry that Mr. Kennedy's shot didn't do more damage."

"The animal is vulnerable only in the stomach and between the thighs. Dick's ball hasn't even marked him; but should the ground strike me as favorable, we shall halt at the northern end of the lake, where Kennedy will find himself in the midst of a whole menagerie, and can make up for lost time."

"Well," said Joe, "I hope then that Mr. Kennedy will hunt the hippopotamus a little; I'd like to taste the meat of that queer-looking beast. It doesn't look exactly natural to get away into the centre of Africa, to feed on snipe and partridge, just as if we were in England."



CHAPTER THIRTY-SECOND.

The Capital of Bornou.—The Islands of the Biddiomahs.—The Condors.—The Doctor's Anxieties.—His Precautions.—An Attack in Mid-air.—The Balloon Covering torn.—The Fall.—Sublime Self-Sacrifice.—The Northern Coast of the Lake.

Since its arrival at Lake Tchad, the balloon had struck a current that edged it farther to the westward. A few clouds tempered the heat of the day, and, besides, a little air could be felt over this vast expanse of water; but about one o'clock, the Victoria, having slanted across this part of the lake, again advanced over the land for a space of seven or eight miles.

The doctor, who was somewhat vexed at first at this turn of his course, no longer thought of complaining when he caught sight of the city of Kouka, the capital of Bornou. He saw it for a moment, encircled by its walls of white clay, and a few rudely-constructed mosques rising clumsily above that conglomeration of houses that look like playing-dice, which form most Arab towns. In the court-yards of the private dwellings, and on the public squares, grew palms and caoutchouc-trees topped with a dome of foliage more than one hundred feet in breadth. Joe called attention to the fact that these immense parasols were in proper accordance with the intense heat of the sun, and made thereon some pious reflections which it were needless to repeat.

Kouka really consists of two distinct towns, separated by the "Dendal," a large boulevard three hundred yards wide, at that hour crowded with horsemen and foot passengers. On one side, the rich quarter stands squarely with its airy and lofty houses, laid out in regular order; on the other, is huddled together the poor quarter, a miserable collection of low hovels of a conical shape, in which a poverty-stricken multitude vegetate rather than live, since Kouka is neither a trading nor a commercial city.

Kennedy thought it looked something like Edinburgh, were that city extended on a plain, with its two distinct boroughs.

But our travellers had scarcely the time to catch even this glimpse of it, for, with the fickleness that characterizes the air-currents of this region, a contrary wind suddenly swept them some forty miles over the surface of Lake Tchad.

Then then were regaled with a new spectacle. They could count the numerous islets of the lake, inhabited by the Biddiomahs, a race of bloodthirsty and formidable pirates, who are as greatly feared when neighbors as are the Touaregs of Sahara.

These estimable people were in readiness to receive the Victoria bravely with stones and arrows, but the balloon quickly passed their islands, fluttering over them, from one to the other with butterfly motion, like a gigantic beetle.

At this moment, Joe, who was scanning the horizon, said to Kennedy:

"There, sir, as you are always thinking of good sport, yonder is just the thing for you!"

"What is it, Joe?"

"This time, the doctor will not disapprove of your shooting."

"But what is it?"

"Don't you see that flock of big birds making for us?"

"Birds?" exclaimed the doctor, snatching his spyglass.

"I see them," replied Kennedy; "there are at least a dozen of them."

"Fourteen, exactly!" said Joe.

"Heaven grant that they may be of a kind sufficiently noxious for the doctor to let me peg away at them!"

"I should not object, but I would much rather see those birds at a distance from us!"

"Why, are you afraid of those fowls?"

"They are condors, and of the largest size. Should they attack us—"

"Well, if they do, we'll defend ourselves. We have a whole arsenal at our disposal. I don't think those birds are so very formidable."

"Who can tell?" was the doctor's only remark.

Ten minutes later, the flock had come within gunshot, and were making the air ring with their hoarse cries. They came right toward the Victoria, more irritated than frightened by her presence.

"How they scream! What a noise!" said Joe.

"Perhaps they don't like to see anybody poaching in their country up in the air, or daring to fly like themselves!"

"Well, now, to tell the truth, when I take a good look at them, they are an ugly, ferocious set, and I should think them dangerous enough if they were armed with Purdy-Moore rifles," admitted Kennedy.

"They have no need of such weapons," said Ferguson, looking very grave.

The condors flew around them in wide circles, their flight growing gradually closer and closer to the balloon. They swept through the air in rapid, fantastic curves, occasionally precipitating themselves headlong with the speed of a bullet, and then breaking their line of projection by an abrupt and daring angle.

The doctor, much disquieted, resolved to ascend so as to escape this dangerous proximity. He therefore dilated the hydrogen in his balloon, and it rapidly rose.

But the condors mounted with him, apparently determined not to part company.

"They seem to mean mischief!" said the hunter, cocking his rifle.

And, in fact, they were swooping nearer, and more than one came within fifty feet of them, as if defying the fire-arms.

"By George, I'm itching to let them have it!" exclaimed Kennedy.

"No, Dick; not now! Don't exasperate them needlessly. That would only be exciting them to attack us!"

"But I could soon settle those fellows!"

"You may think so, Dick. But you are wrong!"

"Why, we have a bullet for each of them!"

"And suppose that they were to attack the upper part of the balloon, what would you do? How would you get at them? Just imagine yourself in the presence of a troop of lions on the plain, or a school of sharks in the open ocean! For travellers in the air, this situation is just as dangerous."

"Are you speaking seriously, doctor?"

"Very seriously, Dick."

"Let us wait, then!"

"Wait! Hold yourself in readiness in case of an attack, but do not fire without my orders."

The birds then collected at a short distance, yet to near that their naked necks, entirely bare of feathers, could be plainly seen, as they stretched them out with the effort of their cries, while their gristly crests, garnished with a comb and gills of deep violet, stood erect with rage. They were of the very largest size, their bodies being more than three feet in length, and the lower surface of their white wings glittering in the sunlight. They might well have been considered winged sharks, so striking was their resemblance to those ferocious rangers of the deep.

"They are following us!" said the doctor, as he saw them ascending with him, "and, mount as we may, they can fly still higher!"

"Well, what are we to do?" asked Kennedy.

The doctor made no answer.

"Listen, Samuel!" said the sportsman. "There are fourteen of those birds; we have seventeen shots at our disposal if we discharge all our weapons. Have we not the means, then, to destroy them or disperse them? I will give a good account of some of them!"

"I have no doubt of your skill, Dick; I look upon all as dead that may come within range of your rifle, but I repeat that, if they attack the upper part of the balloon, you could not get a sight at them. They would tear the silk covering that sustains us, and we are three thousand feet up in the air!"

At this moment, one of the ferocious birds darted right at the balloon, with outstretched beak and claws, ready to rend it with either or both.

"Fire! fire at once!" cried the doctor.

He had scarcely ceased, ere the huge creature, stricken dead, dropped headlong, turning over and over in space as he fell.

Kennedy had already grasped one of the two-barrelled fowling-pieces and Joe was taking aim with another.

Frightened by the report, the condors drew back for a moment, but they almost instantly returned to the charge with extreme fury. Kennedy severed the head of one from its body with his first shot, and Joe broke the wing of another.

"Only eleven left," said he.

Thereupon the birds changed their tactics, and by common consent soared above the balloon. Kennedy glanced at Ferguson. The latter, in spite of his imperturbability, grew pale. Then ensued a moment of terrifying silence. In the next they heard a harsh tearing noise, as of something rending the silk, and the car seemed to sink from beneath the feet of our three aeronauts.

"We are lost!" exclaimed Ferguson, glancing at the barometer, which was now swiftly rising.

"Over with the ballast!" he shouted, "over with it!"

And in a few seconds the last lumps of quartz had disappeared.

"We are still falling! Empty the water-tanks! Do you hear me, Joe? We are pitching into the lake!"

Joe obeyed. The doctor leaned over and looked out. The lake seemed to come up toward him like a rising tide. Every object around grew rapidly in size while they were looking at it. The car was not two hundred feet from the surface of Lake Tchad.

"The provisions! the provisions!" cried the doctor.

And the box containing them was launched into space.

Their descent became less rapid, but the luckless aeronauts were still falling, and into the lake.

"Throw out something—something more!" cried the doctor.

"There is nothing more to throw!" was Kennedy's despairing response.

"Yes, there is!" called Joe, and with a wave of the hand he disappeared like a flash, over the edge of the car.

"Joe! Joe!" exclaimed the doctor, horror-stricken.

The Victoria thus relieved resumed her ascending motion, mounted a thousand feet into the air, and the wind, burying itself in the disinflated covering, bore them away toward the northern part of the lake.

"Lost!" exclaimed the sportsman, with a gesture of despair.

"Lost to save us!" responded Ferguson.

And these men, intrepid as they were, felt the large tears streaming down their cheeks. They leaned over with the vain hope of seeing some trace of their heroic companion, but they were already far away from him.

"What course shall we pursue?" asked Kennedy.

"Alight as soon as possible, Dick, and then wait."

After a sweep of some sixty miles the Victoria halted on a desert shore, on the north of the lake. The anchors caught in a low tree and the sportsman fastened it securely. Night came, but neither Ferguson nor Kennedy could find one moment's sleep.



CHAPTER THIRTY-THIRD.

Conjectures.—Reestablishment of the Victoria's Equilibrium.—Dr. Ferguson's New Calculations.—Kennedy's Hunt.—A Complete Exploration of Lake Tchad.—Tangalia.—The Return.—Lari.

On the morrow, the 13th of May, our travellers, for the first time, reconnoitred the part of the coast on which they had landed. It was a sort of island of solid ground in the midst of an immense marsh. Around this fragment of terra firma grew reeds as lofty as trees are in Europe, and stretching away out of sight.

These impenetrable swamps gave security to the position of the balloon. It was necessary to watch only the borders of the lake. The vast stretch of water broadened away from the spot, especially toward the east, and nothing could be seen on the horizon, neither mainland nor islands.

The two friends had not yet ventured to speak of their recent companion. Kennedy first imparted his conjectures to the doctor.

"Perhaps Joe is not lost after all," he said. "He was a skilful lad, and had few equals as a swimmer. He would find no difficulty in swimming across the Firth of Forth at Edinburgh. We shall see him again—but how and where I know not. Let us omit nothing on our part to give him the chance of rejoining us."

"May God grant it as you say, Dick!" replied the doctor, with much emotion. "We shall do everything in the world to find our lost friend again. Let us, in the first place, see where we are. But, above all things, let us rid the Victoria of this outside covering, which is of no further use. That will relieve us of six hundred and fifty pounds, a weight not to be despised—and the end is worth the trouble!"

The doctor and Kennedy went to work at once, but they encountered great difficulty. They had to tear the strong silk away piece by piece, and then cut it in narrow strips so as to extricate it from the meshes of the network. The tear made by the beaks of the condors was found to be several feet in length.

This operation took at least four hours, but at length the inner balloon once completely extricated did not appear to have suffered in the least degree. The Victoria was thus diminished in size by one fifth, and this difference was sufficiently noticeable to excite Kennedy's surprise.

"Will it be large enough?" he asked.

"Have no fears on that score, I will reestablish the equilibrium, and should our poor Joe return we shall find a way to start off with him again on our old route."

"At the moment of our fall, unless I am mistaken, we were not far from an island."

"Yes, I recollect it," said the doctor, "but that island, like all the islands on Lake Tchad, is, no doubt, inhabited by a gang of pirates and murderers. They certainly witnessed our misfortune, and should Joe fall into their hands, what will become of him unless protected by their superstitions?"

"Oh, he's just the lad to get safely out of the scrape, I repeat. I have great confidence in his shrewdness and skill."

"I hope so. Now, Dick, you may go and hunt in the neighborhood, but don't get far away whatever you do. It has become a pressing necessity for us to renew our stock of provisions, since we had to sacrifice nearly all the old lot."

"Very good, doctor, I shall not be long absent."

Hereupon, Kennedy took a double-barrelled fowling-piece, and strode through the long grass toward a thicket not far off, where the frequent sound of shooting soon let the doctor know that the sportsman was making a good use of his time.

Meanwhile Ferguson was engaged in calculating the relative weight of the articles still left in the car, and in establishing the equipoise of the second balloon. He found that there were still left some thirty pounds of pemmican, a supply of tea and coffee, about a gallon and a half of brandy, and one empty water-tank. All the dried meat had disappeared.

The doctor was aware that, by the loss of the hydrogen in the first balloon, the ascensional force at his disposal was now reduced to about nine hundred pounds. He therefore had to count upon this difference in order to rearrange his equilibrium. The new balloon measured sixty-seven thousand cubic feet, and contained thirty-three thousand four hundred and eighty feet of gas. The dilating apparatus appeared to be in good condition, and neither the battery nor the spiral had been injured.

The ascensional force of the new balloon was then about three thousand pounds, and, in adding together the weight of the apparatus, of the passengers, of the stock of water, of the car and its accessories, and putting aboard fifty gallons of water, and one hundred pounds of fresh meat, the doctor got a total weight of twenty-eight hundred and thirty pounds. He could then take with him one hundred and seventy pounds of ballast, for unforeseen emergencies, and the balloon would be in exact balance with the surrounding atmosphere.

His arrangements were completed accordingly, and he made up for Joe's weight with a surplus of ballast. He spent the whole day in these preparations, and the latter were finished when Kennedy returned. The hunter had been successful, and brought back a regular cargo of geese, wild-duck, snipe, teal, and plover. He went to work at once to draw and smoke the game. Each piece, suspended on a small, thin skewer, was hung over a fire of green wood. When they seemed in good order, Kennedy, who was perfectly at home in the business, packed them away in the car.

On the morrow, the hunter was to complete his supplies.

Evening surprised our travellers in the midst of this work. Their supper consisted of pemmican, biscuit, and tea; and fatigue, after having given them appetite, brought them sleep. Each of them strained eyes and ears into the gloom during his watch, sometimes fancying that they heard the voice of poor Joe; but, alas! the voice that they so longed to hear, was far away.

"At the first streak of day, the doctor aroused Kennedy.

"I have been long and carefully considering what should be done," said he, "to find our companion."

"Whatever your plan may be, doctor, it will suit me. Speak!"

"Above all things, it is important that Joe should hear from us in some way."

"Undoubtedly. Suppose the brave fellow should take it into his head that we have abandoned him?"

"He! He knows us too well for that. Such a thought would never come into his mind. But he must be informed as to where we are."

"How can that be managed?"

"We shall get into our car and be off again through the air."

"But, should the wind bear us away?"

"Happily, it will not. See, Dick! it is carrying us back to the lake; and this circumstance, which would have been vexatious yesterday, is fortunate now. Our efforts, then, will be limited to keeping ourselves above that vast sheet of water throughout the day. Joe cannot fail to see us, and his eyes will be constantly on the lookout in that direction. Perhaps he will even manage to let us know the place of his retreat."

"If he be alone and at liberty, he certainly will."

"And if a prisoner," resumed the doctor, "it not being the practice of the natives to confine their captives, he will see us, and comprehend the object of our researches."

"But, at last," put in Kennedy—"for we must anticipate every thing—should we find no trace—if he should have left no mark to follow him by, what are we to do?"

"We shall endeavor to regain the northern part of the lake, keeping ourselves as much in sight as possible. There we'll wait; we'll explore the banks; we'll search the water's edge, for Joe will assuredly try to reach the shore; and we will not leave the country without having done every thing to find him."

"Let us set out, then!" said the hunter.

The doctor hereupon took the exact bearings of the patch of solid land they were about to leave, and arrived at the conclusion that it lay on the north shore of Lake Tchad, between the village of Lari and the village of Ingemini, both visited by Major Denham. During this time Kennedy was completing his stock of fresh meat. Although the neighboring marshes showed traces of the rhinoceros, the lamantine (or manatee), and the hippopotamus, he had no opportunity to see a single specimen of those animals.

At seven in the morning, but not without great difficulty —which to Joe would have been nothing—the balloon's anchor was detached from its hold, the gas dilated, and the new Victoria rose two hundred feet into the air. It seemed to hesitate at first, and went spinning around, like a top; but at last a brisk current caught it, and it advanced over the lake, and was soon borne away at a speed of twenty miles per hour.

The doctor continued to keep at a height of from two hundred to five hundred feet. Kennedy frequently discharged his rifle; and, when passing over islands, the aeronauts approached them even imprudently, scrutinizing the thickets, the bushes, the underbrush—in fine, every spot where a mass of shade or jutting rock could have afforded a retreat to their companion. They swooped down close to the long pirogues that navigated the lake; and the wild fishermen, terrified at the sight of the balloon, would plunge into the water and regain their islands with every symptom of undisguised affright.

"We can see nothing," said Kennedy, after two hours of search.

"Let us wait a little longer, Dick, and not lose heart. We cannot be far away from the scene of our accident."

By eleven o'clock the balloon had gone ninety miles. It then fell in with a new current, which, blowing almost at right angles to the other, drove them eastward about sixty miles. It next floated over a very large and populous island, which the doctor took to be Farram, on which the capital of the Biddiomahs is situated. Ferguson expected at every moment to see Joe spring up out of some thicket, flying for his life, and calling for help. Were he free, they could pick him up without trouble; were he a prisoner, they could rescue him by repeating the manoeuvre they had practised to save the missionary, and he would soon be with his friends again; but nothing was seen, not a sound was heard. The case seemed desperate.

About half-past two o'clock, the Victoria hove in sight of Tangalia, a village situated on the eastern shore of Lake Tchad, where it marks the extreme point attained by Denham at the period of his exploration.

The doctor became uneasy at this persistent setting of the wind in that direction, for he felt that he was being thrown back to the eastward, toward the centre of Africa, and the interminable deserts of that region.

"We must absolutely come to a halt," said he, "and even alight. For Joe's sake, particularly, we ought to go back to the lake; but, to begin with, let us endeavor to find an opposite current."

During more than an hour he searched at different altitudes: the balloon always came back toward the mainland. But at length, at the height of a thousand feet, a very violent breeze swept to the northwestward.

It was out of the question that Joe should have been detained on one of the islands of the lake; for, in such case he would certainly have found means to make his presence there known. Perhaps he had been dragged to the mainland. The doctor was reasoning thus to himself, when he again came in sight of the northern shore of Lake Tchad.

As for supposing that Joe had been drowned, that was not to be believed for a moment. One horrible thought glanced across the minds of both Kennedy and the doctor: caymans swarm in these waters! But neither one nor the other had the courage to distinctly communicate this impression. However, it came up to them so forcibly at last that the doctor said, without further preface:

"Crocodiles are found only on the shores of the islands or of the lake, and Joe will have skill enough to avoid them. Besides, they are not very dangerous; and the Africans bathe with impunity, and quite fearless of their attacks."

Kennedy made no reply. He preferred keeping quiet to discussing this terrible possibility.

The doctor made out the town of Lari about five o'clock in the evening. The inhabitants were at work gathering in their cotton-crop in front of their huts, constructed of woven reeds, and standing in the midst of clean and neatly-kept enclosures. This collection of about fifty habitations occupied a slight depression of the soil, in a valley extending between two low mountains. The force of the wind carried the doctor farther onward than he wanted to go; but it changed a second time, and bore him back exactly to his starting-point, on the sort of enclosed island where he had passed the preceding night. The anchor, instead of catching the branches of the tree, took hold in the masses of reeds mixed with the thick mud of the marshes, which offered considerable resistance.

The doctor had much difficulty in restraining the balloon; but at length the wind died away with the setting in of nightfall; and the two friends kept watch together in an almost desperate state of mind.



CHAPTER THIRTY-FOURTH.

The Hurricane.—A Forced Departure.—Loss of an Anchor.—Melancholy Reflections.—The Resolution adopted.—The Sand-Storm.—The Buried Caravan.—A Contrary yet Favorable Wind.—The Return southward.—Kennedy at his Post.

At three o'clock in the morning the wind was raging. It beat down with such violence that the Victoria could not stay near the ground without danger. It was thrown almost flat over upon its side, and the reeds chafed the silk so roughly that it seemed as though they would tear it.

"We must be off, Dick," said the doctor; "we cannot remain in this situation."

"But, doctor, what of Joe?"

"I am not likely to abandon him. No, indeed! and should the hurricane carry me a thousand miles to the northward, I will return! But here we are endangering the safety of all."

"Must we go without him?" asked the Scot, with an accent of profound grief.

"And do you think, then," rejoined Ferguson, "that my heart does not bleed like your own? Am I not merely obeying an imperious necessity?"

"I am entirely at your orders," replied the hunter; "let us start!"

But their departure was surrounded with unusual difficulty. The anchor, which had caught very deeply, resisted all their efforts to disengage it; while the balloon, drawing in the opposite direction, increased its tension. Kennedy could not get it free. Besides, in his present position, the manoeuvre had become a very perilous one, for the Victoria threatened to break away before he should be able to get into the car again.

The doctor, unwilling to run such a risk, made his friend get into his place, and resigned himself to the alternative of cutting the anchor-rope. The Victoria made one bound of three hundred feet into the air, and took her route directly northward.

Ferguson had no other choice than to scud before the storm. He folded his arms, and soon became absorbed in his own melancholy reflections.

After a few moments of profound silence, he turned to Kennedy, who sat there no less taciturn.

"We have, perhaps, been tempting Providence," said he; "it does not belong to man to undertake such a journey!" —and a sigh of grief escaped him as he spoke.

"It is but a few days," replied the sportsman, "since we were congratulating ourselves upon having escaped so many dangers! All three of us were shaking hands!"

"Poor Joe! kindly and excellent disposition! brave and candid heart! Dazzled for a moment by his sudden discovery of wealth, he willingly sacrificed his treasures! And now, he is far from us; and the wind is carrying us still farther away with resistless speed!"

"Come, doctor, admitting that he may have found refuge among the lake tribes, can he not do as the travellers who visited them before us, did;—like Denham, like Barth? Both of those men got back to their own country."

"Ah! my dear Dick! Joe doesn't know one word of the language; he is alone, and without resources. The travellers of whom you speak did not attempt to go forward without sending many presents in advance of them to the chiefs, and surrounded by an escort armed and trained for these expeditions. Yet, they could not avoid sufferings of the worst description! What, then, can you expect the fate of our companion to be? It is horrible to think of, and this is one of the worst calamities that it has ever been my lot to endure!"

"But, we'll come back again, doctor!"

"Come back, Dick? Yes, if we have to abandon the balloon! if we should be forced to return to Lake Tchad on foot, and put ourselves in communication with the Sultan of Bornou! The Arabs cannot have retained a disagreeable remembrance of the first Europeans."

"I will follow you, doctor," replied the hunter, with emphasis. "You may count upon me! We would rather give up the idea of prosecuting this journey than not return. Joe forgot himself for our sake; we will sacrifice ourselves for his!"

This resolve revived some hope in the hearts of these two men; they felt strong in the same inspiration. Ferguson forthwith set every thing at work to get into a contrary current, that might bring him back again to Lake Tchad; but this was impracticable at that moment, and even to alight was out of the question on ground completely bare of trees, and with such a hurricane blowing.

The Victoria thus passed over the country of the Tibbous, crossed the Belad el Djerid, a desert of briers that forms the border of the Soudan, and advanced into the desert of sand streaked with the long tracks of the many caravans that pass and repass there. The last line of vegetation was speedily lost in the dim southern horizon, not far from the principal oasis in this part of Africa, whose fifty wells are shaded by magnificent trees; but it was impossible to stop. An Arab encampment, tents of striped stuff, some camels, stretching out their viper-like heads and necks along the sand, gave life to this solitude, but the Victoria sped by like a shooting-star, and in this way traversed a distance of sixty miles in three hours, without Ferguson being able to check or guide her course.

"We cannot halt, we cannot alight!" said the doctor; "not a tree, not an inequality of the ground! Are we then to be driven clear across Sahara? Surely, Heaven is indeed against us!"

He was uttering these words with a sort of despairing rage, when suddenly he saw the desert sands rising aloft in the midst of a dense cloud of dust, and go whirling through the air, impelled by opposing currents.

Amid this tornado, an entire caravan, disorganized, broken, and overthrown, was disappearing beneath an avalanche of sand. The camels, flung pell-mell together, were uttering dull and pitiful groans; cries and howls of despair were heard issuing from that dusty and stifling cloud, and, from time to time, a parti-colored garment cut the chaos of the scene with its vivid hues, and the moaning and shrieking sounded over all, a terrible accompaniment to this spectacle of destruction.

Ere long the sand had accumulated in compact masses; and there, where so recently stretched a level plain as far as the eye could see, rose now a ridgy line of hillocks, still moving from beneath—the vast tomb of an entire caravan!

The doctor and Kennedy, pallid with emotion, sat transfixed by this fearful spectacle. They could no longer manage their balloon, which went whirling round and round in contending currents, and refused to obey the different dilations of the gas. Caught in these eddies of the atmosphere, it spun about with a rapidity that made their heads reel, while the car oscillated and swung to and fro violently at the same time. The instruments suspended under the awning clattered together as though they would be dashed to pieces; the pipes of the spiral bent to and fro, threatening to break at every instant; and the water-tanks jostled and jarred with tremendous din. Although but two feet apart, our aeronauts could not hear each other speak, but with firmly-clinched hands they clung convulsively to the cordage, and endeavored to steady themselves against the fury of the tempest.

Kennedy, with his hair blown wildly about his face, looked on without speaking; but the doctor had regained all his daring in the midst of this deadly peril, and not a sign of his emotion was betrayed in his countenance, even when, after a last violent twirl, the Victoria stopped suddenly in the midst of a most unlooked-for calm; the north wind had abruptly got the upper hand, and now drove her back with equal rapidity over the route she had traversed in the morning.

"Whither are we going now?" cried Kennedy.

"Let us leave that to Providence, my dear Dick; I was wrong in doubting it. It knows better than we, and here we are, returning to places that we had expected never to see again!"

The surface of the country, which had looked so flat and level when they were coming, now seemed tossed and uneven, like the ocean-billows after a storm; a long succession of hillocks, that had scarcely settled to their places yet, indented the desert; the wind blew furiously, and the balloon fairly flew through the atmosphere.

The direction taken by our aeronauts differed somewhat from that of the morning, and thus about nine o'clock, instead of finding themselves again near the borders of Lake Tchad, they saw the desert still stretching away before them.

Kennedy remarked the circumstance.

"It matters little," replied the doctor, "the important point is to return southward; we shall come across the towns of Bornou, Wouddie, or Kouka, and I should not hesitate to halt there."

"If you are satisfied, I am content," replied the Scot, "but Heaven grant that we may not be reduced to cross the desert, as those unfortunate Arabs had to do! What we saw was frightful!"

"It often happens, Dick; these trips across the desert are far more perilous than those across the ocean. The desert has all the dangers of the sea, including the risk of being swallowed up, and added thereto are unendurable fatigues and privations."

"I think the wind shows some symptoms of moderating; the sand-dust is less dense; the undulations of the surface are diminishing, and the sky is growing clearer."

"So much the better! We must now reconnoitre attentively with our glasses, and take care not to omit a single point."

"I will look out for that, doctor, and not a tree shall be seen without my informing you of it."

And, suiting the action to the word, Kennedy took his station, spy-glass in hand, at the forward part of the car.



CHAPTER THIRTY-FIFTH.

What happened to Joe.—The Island of the Biddiomahs.—The Adoration shown him.—The Island that sank.—The Shores of the Lake.—The Tree of the Serpents.—The Foot-Tramp.—Terrible Suffering.—Mosquitoes and Ants.—Hunger.—The Victoria seen.—She disappears.—The Swamp. —One Last Despairing Cry.

What had become of Joe, while his master was thus vainly seeking for him?

When he had dashed headlong into the lake, his first movement on coming to the surface was to raise his eyes and look upward. He saw the Victoria already risen far above the water, still rapidly ascending and growing smaller and smaller. It was soon caught in a rapid current and disappeared to the northward. His master—both his friends were saved!

"How lucky it was," thought he, "that I had that idea to throw myself out into the lake! Mr. Kennedy would soon have jumped at it, and he would not have hesitated to do as I did, for nothing's more natural than for one man to give himself up to save two others. That's mathematics!"

Satisfied on this point, Joe began to think of himself. He was in the middle of a vast lake, surrounded by tribes unknown to him, and probably ferocious. All the greater reason why he should get out of the scrape by depending only on himself. And so he gave himself no farther concern about it.

Before the attack by the birds of prey, which, according to him, had behaved like real condors, he had noticed an island on the horizon, and determining to reach it, if possible, he put forth all his knowledge and skill in the art of swimming, after having relieved himself of the most troublesome part of his clothing. The idea of a stretch of five or six miles by no means disconcerted him; and therefore, so long as he was in the open lake, he thought only of striking out straight ahead and manfully.

In about an hour and a half the distance between him and the island had greatly diminished.

But as he approached the land, a thought, at first fleeting and then tenacious, arose in his mind. He knew that the shores of the lake were frequented by huge alligators, and was well aware of the voracity of those monsters.

Now, no matter how much he was inclined to find every thing in this world quite natural, the worthy fellow was no little disturbed by this reflection. He feared greatly lest white flesh like his might be particularly acceptable to the dreaded brutes, and advanced only with extreme precaution, his eyes on the alert on both sides and all around him. At length, he was not more than one hundred yards from a bank, covered with green trees, when a puff of air strongly impregnated with a musky odor reached him.

"There!" said he to himself, "just what I expected. The crocodile isn't far off!"

With this he dived swiftly, but not sufficiently so to avoid coming into contact with an enormous body, the scaly surface of which scratched him as he passed. He thought himself lost and swam with desperate energy. Then he rose again to the top of the water, took breath and dived once more. Thus passed a few minutes of unspeakable anguish, which all his philosophy could not overcome, for he thought, all the while, that he heard behind him the sound of those huge jaws ready to snap him up forever. In this state of mind he was striking out under the water as noiselessly as possible when he felt himself seized by the arm and then by the waist.

Poor Joe! he gave one last thought to his master; and began to struggle with all the energy of despair, feeling himself the while drawn along, but not toward the bottom of the lake, as is the habit of the crocodile when about to devour its prey, but toward the surface.

So soon as he could get breath and look around him, he saw that he was between two natives as black as ebony, who held him, with a firm gripe, and uttered strange cries.

"Ha!" said Joe, "blacks instead of crocodiles! Well, I prefer it as it is; but how in the mischief dare these fellows go in bathing in such places?"

Joe was not aware that the inhabitants of the islands of Lake Tchad, like many other negro tribes, plunge with impunity into sheets of water infested with crocodiles and caymans, and without troubling their heads about them. The amphibious denizens of this lake enjoy the well-deserved reputation of being quite inoffensive.

But had not Joe escaped one peril only to fall into another? That was a question which he left events to decide; and, since he could not do otherwise, he allowed himself to be conducted to the shore without manifesting any alarm.
