"Evidently," thought he, "these chaps saw the Victoria skimming the waters of the lake, like a monster of the air. They were the distant witnesses of my tumble, and they can't fail to have some respect for a man that fell from the sky! Let them have their own way, then."

Joe was at this stage of his meditations, when he was landed amid a yelling crowd of both sexes, and all ages and sizes, but not of all colors. In fine, he was surrounded by a tribe of Biddiomahs as black as jet. Nor had he to blush for the scantiness of his costume, for he saw that he was in "undress" in the highest style of that country.

But before he had time to form an exact idea of the situation, there was no mistaking the agitation of which he instantly became the object, and this soon enabled him to pluck up courage, although the adventure of Kazah did come back rather vividly to his memory.

"I foresee that they are going to make a god of me again," thought he, "some son of the moon most likely. Well, one trade's as good as another when a man has no choice. The main thing is to gain time. Should the Victoria pass this way again, I'll take advantage of my new position to treat my worshippers here to a miracle when I go sailing up into the sky!"

While Joe's thoughts were running thus, the throng pressed around him. They prostrated themselves before him; they howled; they felt him; they became even annoyingly familiar; but at the same time they had the consideration to offer him a superb banquet consisting of sour milk and rice pounded in honey. The worthy fellow, making the best of every thing, took one of the heartiest luncheons he ever ate in his life, and gave his new adorers an exalted idea of how the gods tuck away their food upon grand occasions.

When evening came, the sorcerers of the island took him respectfully by the hand, and conducted him to a sort of house surrounded with talismans; but, as he was entering it, Joe cast an uneasy look at the heaps of human bones that lay scattered around this sanctuary. But he had still more time to think about them when he found himself at last shut up in the cabin.

During the evening and through a part of the night, he heard festive chantings, the reverberations of a kind of drum, and a clatter of old iron, which were very sweet, no doubt, to African ears. Then there were howling choruses, accompanied by endless dances by gangs of natives who circled round and round the sacred hut with contortions and grimaces.

Joe could catch the sound of this deafening orchestra, through the mud and reeds of which his cabin was built; and perhaps under other circumstances he might have been amused by these strange ceremonies; but his mind was soon disturbed by quite different and less agreeable reflections. Even looking at the bright side of things, he found it both stupid and sad to be left alone in the midst of this savage country and among these wild tribes. Few travellers who had penetrated to these regions had ever again seen their native land. Moreover, could he trust to the worship of which he saw himself the object? He had good reason to believe in the vanity of human greatness; and he asked himself whether, in this country, adoration did not sometimes go to the length of eating the object adored!

But, notwithstanding this rather perplexing prospect, after some hours of meditation, fatigue got the better of his gloomy thoughts, and Joe fell into a profound slumber, which would have lasted no doubt until sunrise, had not a very unexpected sensation of dampness awakened the sleeper. Ere long this dampness became water, and that water gained so rapidly that it had soon mounted to Joe's waist.

"What can this be?" said he; "a flood! a water-spout! or a new torture invented by these blacks? Faith, though, I'm not going to wait here till it's up to my neck!"

And, so saying, he burst through the frail wall with a jog of his powerful shoulder, and found himself—where? —in the open lake! Island there was none. It had sunk during the night. In its place, the watery immensity of Lake Tchad!

"A poor country for the land-owners!" said Joe, once more vigorously resorting to his skill in the art of natation.

One of those phenomena, which are by no means unusual on Lake Tchad, had liberated our brave Joe. More than one island, that previously seemed to have the solidity of rock, has been submerged in this way; and the people living along the shores of the mainland have had to pick up the unfortunate survivors of these terrible catastrophes.

Joe knew nothing about this peculiarity of the region, but he was none the less ready to profit by it. He caught sight of a boat drifting about, without occupants, and was soon aboard of it. He found it to be but the trunk of a tree rudely hollowed out; but there were a couple of paddles in it, and Joe, availing himself of a rapid current, allowed his craft to float along.

"But let us see where we are," he said. "The polar-star there, that does its work honorably in pointing out the direction due north to everybody else, will, most likely, do me that service."

He discovered, with satisfaction, that the current was taking him toward the northern shore of the lake, and he allowed himself to glide with it. About two o'clock in the morning he disembarked upon a promontory covered with prickly reeds, that proved very provoking and inconvenient even to a philosopher like him; but a tree grew there expressly to offer him a bed among its branches, and Joe climbed up into it for greater security, and there, without sleeping much, however, awaited the dawn of day.

When morning had come with that suddenness which is peculiar to the equatorial regions, Joe cast a glance at the tree which had sheltered him during the last few hours, and beheld a sight that chilled the marrow in his bones. The branches of the tree were literally covered with snakes and chameleons! The foliage actually was hidden beneath their coils, so that the beholder might have fancied that he saw before him a new kind of tree that bore reptiles for its leaves and fruit. And all this horrible living mass writhed and twisted in the first rays of the morning sun! Joe experienced a keen sensation or terror mingled with disgust, as he looked at it, and he leaped precipitately from the tree amid the hissings of these new and unwelcome bedfellows.

"Now, there's something that I would never have believed!" said he.

He was not aware that Dr. Vogel's last letters had made known this singular feature of the shores of Lake Tchad, where reptiles are more numerous than in any other part of the world. But after what he had just seen, Joe determined to be more circumspect for the future; and, taking his bearings by the sun, he set off afoot toward the northeast, avoiding with the utmost care cabins, huts, hovels, and dens of every description, that might serve in any manner as a shelter for human beings.

How often his gaze was turned upward to the sky! He hoped to catch a glimpse, each time, of the Victoria; and, although he looked vainly during all that long, fatiguing day of sore foot-travel, his confident reliance on his master remained undiminished. Great energy of character was needed to enable him thus to sustain the situation with philosophy. Hunger conspired with fatigue to crush him, for a man's system is not greatly restored and fortified by a diet of roots, the pith of plants, such as the Mele, or the fruit of the doum palm-tree; and yet, according to his own calculations, Joe was enabled to push on about twenty miles to the westward.

His body bore in scores of places the marks of the thorns with which the lake-reeds, the acacias, the mimosas, and other wild shrubbery through which he had to force his way, are thickly studded; and his torn and bleeding feet rendered walking both painful and difficult. But at length he managed to react against all these sufferings; and when evening came again, he resolved to pass the night on the shores of Lake Tchad.

There he had to endure the bites of myriads of insects —gnats, mosquitoes, ants half an inch long, literally covered the ground; and, in less than two hours, Joe had not a rag remaining of the garments that had covered him, the insects having devoured them! It was a terrible night, that did not yield our exhausted traveller an hour of sleep. During all this time the wild-boars and native buffaloes, reenforced by the ajoub—a very dangerous species of lamantine —carried on their ferocious revels in the bushes and under the waters of the lake, filling the night with a hideous concert. Joe dared scarcely breathe. Even his courage and coolness had hard work to bear up against so terrible a situation.

At length, day came again, and Joe sprang to his feet precipitately; but judge of the loathing he felt when he saw what species of creature had shared his couch—a toad!—but a toad five inches in length, a monstrous, repulsive specimen of vermin that sat there staring at him with huge round eyes. Joe felt his stomach revolt at the sight, and, regaining a little strength from the intensity of his repugnance, he rushed at the top of his speed and plunged into the lake. This sudden bath somewhat allayed the pangs of the itching that tortured his whole body; and, chewing a few leaves, he set forth resolutely, again feeling an obstinate resolution in the act, for which he could hardly account even to his own mind. He no longer seemed to have entire control of his own acts, and, nevertheless, he felt within him a strength superior to despair.

However, he began now to suffer terribly from hunger. His stomach, less resigned than he was, rebelled, and he was obliged to fasten a tendril of wild-vine tightly about his waist. Fortunately, he could quench his thirst at any moment, and, in recalling the sufferings he had undergone in the desert, he experienced comparative relief in his exemption from that other distressing want.

"What can have become of the Victoria?" he wondered. "The wind blows from the north, and she should be carried back by it toward the lake. No doubt the doctor has gone to work to right her balance, but yesterday would have given him time enough for that, so that may be to-day—but I must act just as if I was never to see him again. After all, if I only get to one of the large towns on the lake, I'll find myself no worse off than the travellers my master used to talk about. Why shouldn't I work my way out of the scrape as well as they did? Some of them got back home again. Come, then! the deuce! Cheer up, my boy!"

Thus talking to himself and walking on rapidly, Joe came right upon a horde of natives in the very depths of the forest, but he halted in time and was not seen by them. The negroes were busy poisoning arrows with the juice of the euphorbium—a piece of work deemed a great affair among these savage tribes, and carried on with a sort of ceremonial solemnity.

Joe, entirely motionless and even holding his breath, was keeping himself concealed in a thicket, when, happening to raise his eyes, he saw through an opening in the foliage the welcome apparition of the balloon—the Victoria herself—moving toward the lake, at a height of only about one hundred feet above him. But he could not make himself heard; he dared not, could not make his friends even see him!

Tears came to his eyes, not of grief but of thankfulness; his master was then seeking him; his master had not left him to perish! He would have to wait for the departure of the blacks; then he could quit his hiding-place and run toward the borders of Lake Tchad!

But by this time the Victoria was disappearing in the distant sky. Joe still determined to wait for her; she would come back again, undoubtedly. She did, indeed, return, but farther to the eastward. Joe ran, gesticulated, shouted—but all in vain! A strong breeze was sweeping the balloon away with a speed that deprived him of all hope.

For the first time, energy and confidence abandoned the heart of the unfortunate man. He saw that he was lost. He thought his master gone beyond all prospect of return. He dared no longer think; he would no longer reflect!

Like a crazy man, his feet bleeding, his body cut and torn, he walked on during all that day and a part of the next night. He even dragged himself along, sometimes on his knees, sometimes with his hands. He saw the moment nigh when all his strength would fail, and nothing would be left to him but to sink upon the ground and die.

Thus working his way along, he at length found himself close to a marsh, or what he knew would soon become a marsh, for night had set in some hours before, and he fell by a sudden misstep into a thick, clinging mire. In spite of all his efforts, in spite of his desperate struggles, he felt himself sinking gradually in the swampy ooze, and in a few minutes he was buried to his waist.

"Here, then, at last, is death!" he thought, in agony, "and what a death!"

He now began to struggle again, like a madman; but his efforts only served to bury him deeper in the tomb that the poor doomed lad was hollowing for himself; not a log of wood or a branch to buoy him up; not a reed to which he might cling! He felt that all was over! His eyes convulsively closed!

"Master! master!—Help!" were his last words; but his voice, despairing, unaided, half stifled already by the rising mire, died away feebly on the night.



CHAPTER THIRTY-SIXTH.

A Throng of People on the Horizon.—A Troop of Arabs.—The Pursuit. —It is He.—Fall from Horseback.—The Strangled Arab.—A Ball from Kennedy.—Adroit Manoeuvres.—Caught up flying.—Joe saved at last.

From the moment when Kennedy resumed his post of observation in the front of the car, he had not ceased to watch the horizon with his utmost attention.

After the lapse of some time he turned toward the doctor and said:

"If I am not greatly mistaken I can see, off yonder in the distance, a throng of men or animals moving. It is impossible to make them out yet, but I observe that they are in violent motion, for they are raising a great cloud of dust."

"May it not be another contrary breeze?" said the doctor, "another whirlwind coming to drive us back northward again?" and while speaking he stood up to examine the horizon.

"I think not, Samuel; it is a troop of gazelles or of wild oxen."

"Perhaps so, Dick; but yon throng is some nine or ten miles from us at least, and on my part, even with the glass, I can make nothing of it!"

"At all events I shall not lose sight of it. There is something remarkable about it that excites my curiosity. Sometimes it looks like a body of cavalry manoeuvring. Ah! I was not mistaken. It is, indeed, a squadron of horsemen. Look—look there!"

The doctor eyed the group with great attention, and, after a moment's pause, remarked:

"I believe that you are right. It is a detachment of Arabs or Tibbous, and they are galloping in the same direction with us, as though in flight, but we are going faster than they, and we are rapidly gaining on them. In half an hour we shall be near enough to see them and know what they are."

Kennedy had again lifted his glass and was attentively scrutinizing them. Meanwhile the crowd of horsemen was becoming more distinctly visible, and a few were seen to detach themselves from the main body.

"It is some hunting manoeuvre, evidently," said Kennedy. "Those fellows seem to be in pursuit of something. I would like to know what they are about."

"Patience, Dick! In a little while we shall overtake them, if they continue on the same route. We are going at the rate of twenty miles per hour, and no horse can keep up with that."

Kennedy again raised his glass, and a few minutes later he exclaimed:

"They are Arabs, galloping at the top of their speed; I can make them out distinctly. They are about fifty in number. I can see their bournouses puffed out by the wind. It is some cavalry exercise that they are going through. Their chief is a hundred paces ahead of them and they are rushing after him at headlong speed."

"Whoever they may be, Dick, they are not to be feared, and then, if necessary, we can go higher."

"Wait, doctor—wait a little!"

"It's curious," said Kennedy again, after a brief pause, "but there's something going on that I can't exactly explain. By the efforts they make, and the irregularity of their line, I should fancy that those Arabs are pursuing some one, instead of following."

"Are you certain of that, Dick?"

"Oh! yes, it's clear enough now. I am right! It is a pursuit—a hunt—but a man-hunt! That is not their chief riding ahead of them, but a fugitive."

"A fugitive!" exclaimed the doctor, growing more and more interested.

"Yes!"

"Don't lose sight of him, and let us wait!"

Three or four miles more were quickly gained upon these horsemen, who nevertheless were dashing onward with incredible speed.

"Doctor! doctor!" shouted Kennedy in an agitated voice.

"What is the matter, Dick?"

"Is it an illusion? Can it be possible?"

"What do you mean?"

"Wait!" and so saying, the Scot wiped the sights of his spy-glass carefully, and looked through it again intently.

"Well?" questioned the doctor.

"It is he, doctor!"

"He!" exclaimed Ferguson with emotion.

"It is he! no other!" and it was needless to pronounce the name.

"Yes! it is he! on horseback, and only a hundred paces in advance of his enemies! He is pursued!"

"It is Joe—Joe himself!" cried the doctor, turning pale.

"He cannot see us in his flight!"

"He will see us, though!" said the doctor, lowering the flame of his blow-pipe.

"But how?"

"In five minutes we shall be within fifty feet of the ground, and in fifteen we shall be right over him!"

"We must let him know it by firing a gun!"

"No! he can't turn back to come this way. He's headed off!"

"What shall we do, then?"

"We must wait."

"Wait?—and these Arabs!"

"We shall overtake them. We'll pass them. We are not more than two miles from them, and provided that Joe's horse holds out!"

"Great God!" exclaimed Kennedy, suddenly.

"What is the matter?"

Kennedy had uttered a cry of despair as he saw Joe fling himself to the ground. His horse, evidently exhausted, had just fallen headlong.

"He sees us!" cried the doctor, "and he motions to us, as he gets upon his feet!"

"But the Arabs will overtake him! What is he waiting for? Ah! the brave lad! Huzza!" shouted the sportsman, who could no longer restrain his feelings.

Joe, who had immediately sprung up after his fall, just as one of the swiftest horsemen rushed upon him, bounded like a panther, avoided his assailant by leaping to one side, jumped up behind him on the crupper, seized the Arab by the throat, and, strangling him with his sinewy hands and fingers of steel, flung him on the sand, and continued his headlong flight.

A tremendous howl was heard from the Arabs, but, completely engrossed by the pursuit, they had not taken notice of the balloon, which was now but five hundred paces behind them, and only about thirty feet from the ground. On their part, they were not twenty lengths of their horses from the fugitive.

One of them was very perceptibly gaining on Joe, and was about to pierce him with his lance, when Kennedy, with fixed eye and steady hand, stopped him short with a ball, that hurled him to the earth.

Joe did not even turn his head at the report. Some of the horsemen reined in their barbs, and fell on their faces in the dust as they caught sight of the Victoria; the rest continued their pursuit.

"But what is Joe about?" said Kennedy; "he don't stop!"

"He's doing better than that, Dick! I understand him! He's keeping on in the same direction as the balloon. He relies upon our intelligence. Ah! the noble fellow! We'll carry him off in the very teeth of those Arab rascals! We are not more than two hundred paces from him!"

"What are we to do?" asked Kennedy.

"Lay aside your rifle,Dick."

And the Scot obeyed the request at once.

"Do you think that you can hold one hundred and fifty pounds of ballast in your arms?"

"Ay, more than that!"

"No! That will be enough!"

And the doctor proceeded to pile up bags of sand in Kennedy's arms.

"Hold yourself in readiness in the back part of the car, and be prepared to throw out that ballast at a single effort. But, for your life, don't do so until I give the word!"

"Be easy on that point."

"Otherwise, we should miss Joe, and he would be lost."

"Count upon me!"

The Victoria at that moment almost commanded the troop of horsemen who were still desperately urging their steeds at Joe's heels. The doctor, standing in the front of the car, held the ladder clear, ready to throw it at any moment. Meanwhile, Joe had still maintained the distance between himself and his pursuers—say about fifty feet. The Victoria was now ahead of the party.

"Attention!" exclaimed the doctor to Kennedy.

"I'm ready!"

"Joe, look out for yourself!" shouted the doctor in his sonorous, ringing voice, as he flung out the ladder, the lowest ratlines of which tossed up the dust of the road.

As the doctor shouted, Joe had turned his head, but without checking his horse. The ladder dropped close to him, and at the instant he grasped it the doctor again shouted to Kennedy:

"Throw ballast!"

"It's done!"

And the Victoria, lightened by a weight greater than Joe's, shot up one hundred and fifty feet into the air.

Joe clung with all his strength to the ladder during the wide oscillations that it had to describe, and then making an indescribable gesture to the Arabs, and climbing with the agility of a monkey, he sprang up to his companions, who received him with open arms.

The Arabs uttered a scream of astonishment and rage. The fugitive had been snatched from them on the wing, and the Victoria was rapidly speeding far beyond their reach.

"Master! Kennedy!" ejaculated Joe, and overwhelmed, at last, with fatigue and emotion, the poor fellow fainted away, while Kennedy, almost beside himself, kept exclaiming:

"Saved—saved!"

"Saved indeed!" murmured the doctor, who had recovered all his phlegmatic coolness.

Joe was almost naked. His bleeding arms, his body covered with cuts and bruises, told what his sufferings had been. The doctor quietly dressed his wounds, and laid him comfortably under the awning.

Joe soon returned to consciousness, and asked for a glass of brandy, which the doctor did not see fit to refuse, as the faithful fellow had to be indulged.

After he had swallowed the stimulant, Joe grasped the hands of his two friends and announced that he was ready to relate what had happened to him.

But they would not allow him to talk at that time, and he sank back into a profound sleep, of which he seemed to have the greatest possible need.

The Victoria was then taking an oblique line to the westward. Driven by a tempestuous wind, it again approached the borders of the thorny desert, which the travellers descried over the tops of palm-trees, bent and broken by the storm; and, after having made a run of two hundred miles since rescuing Joe, it passed the tenth degree of east longitude about nightfall.



CHAPTER THIRTY-SEVENTH.

The Western Route.—Joe wakes up.—His Obstinacy.—End of Joe's Narrative.—Tagelei.—Kennedy's Anxieties.—The Route to the North.—A Night near Aghades.

During the night the wind lulled as though reposing after the boisterousness of the day, and the Victoria remained quietly at the top of the tall sycamore. The doctor and Kennedy kept watch by turns, and Joe availed himself of the chance to sleep most sturdily for twenty-four hours at a stretch.

"That's the remedy he needs," said Dr. Ferguson. "Nature will take charge of his care."

With the dawn the wind sprang up again in quite strong, and moreover capricious gusts. It shifted abruptly from south to north, but finally the Victoria was carried away by it toward the west.

The doctor, map in hand, recognized the kingdom of Damerghou, an undulating region of great fertility, in which the huts that compose the villages are constructed of long reeds interwoven with branches of the asclepia. The grain-mills were seen raised in the cultivated fields, upon small scaffoldings or platforms, to keep them out of the reach of the mice and the huge ants of that country.

They soon passed the town of Zinder, recognized by its spacious place of execution, in the centre of which stands the "tree of death." At its foot the executioner stands waiting, and whoever passes beneath its shadow is immediately hung!

Upon consulting his compass, Kennedy could not refrain from saying:

"Look! we are again moving northward."

"No matter; if it only takes us to Timbuctoo, we shall not complain. Never was a finer voyage accomplished under better circumstances!"

"Nor in better health," said Joe, at that instant thrusting his jolly countenance from between the curtains of the awning.

"There he is! there's our gallant friend—our preserver!" exclaimed Kennedy, cordially.—"How goes it, Joe?"

"Oh! why, naturally enough, Mr. Kennedy, very naturally! I never felt better in my life! Nothing sets a man up like a little pleasure-trip with a bath in Lake Tchad to start on—eh, doctor?"

"Brave fellow!" said Ferguson, pressing Joe's hand, "what terrible anxiety you caused us!"

"Humph! and you, sir? Do you think that I felt easy in my mind about you, gentlemen? You gave me a fine fright, let me tell you!"

"We shall never agree in the world, Joe, if you take things in that style."

"I see that his tumble hasn't changed him a bit," added Kennedy.

"Your devotion and self-forgetfulness were sublime, my brave lad, and they saved us, for the Victoria was falling into the lake, and, once there, nobody could have extricated her."

"But, if my devotion, as you are pleased to call my summerset, saved you, did it not save me too, for here we are, all three of us, in first-rate health? Consequently we have nothing to squabble about in the whole affair."

"Oh! we can never come to a settlement with that youth," said the sportsman.

"The best way to settle it," replied Joe, "is to say nothing more about the matter. What's done is done. Good or bad, we can't take it back."

"You obstinate fellow!" said the doctor, laughing; "you can't refuse, though, to tell us your adventures, at all events."

"Not if you think it worth while. But, in the first place, I'm going to cook this fat goose to a turn, for I see that Mr. Kennedy has not wasted his time."

"All right, Joe!"

"Well, let us see then how this African game will sit on a European stomach!"

The goose was soon roasted by the flame of the blow-pipe, and not long afterward was comfortably stowed away. Joe took his own good share, like a man who had eaten nothing for several days. After the tea and the punch, he acquainted his friends with his recent adventures. He spoke with some emotion, even while looking at things with his usual philosophy. The doctor could not refrain from frequently pressing his hand when he saw his worthy servant more considerate of his master's safety than of his own, and, in relation to the sinking of the island of the Biddiomahs, he explained to him the frequency of this phenomenon upon Lake Tchad.

At length Joe, continuing his recital, arrived at the point where, sinking in the swamp, he had uttered a last cry of despair.

"I thought I was gone," said he, "and as you came right into my mind, I made a hard fight for it. How, I couldn't tell you—but I'd made up my mind that I wouldn't go under without knowing why. Just then, I saw—two or three feet from me—what do you think? the end of a rope that had been fresh cut; so I took leave to make another jerk, and, by hook or by crook, I got to the rope. When I pulled, it didn't give; so I pulled again and hauled away and there I was on dry ground! At the end of the rope, I found an anchor! Ah, master, I've a right to call that the anchor of safety, anyhow, if you have no objection. I knew it again! It was the anchor of the Victoria! You had grounded there! So I followed the direction of the rope and that gave me your direction, and, after trying hard a few times more, I got out of the swamp. I had got my strength back with my spunk, and I walked on part of the night away from the lake, until I got to the edge of a very big wood. There I saw a fenced-in place, where some horses were grazing, without thinking of any harm. Now, there are times when everybody knows how to ride a horse, are there not, doctor? So I didn't spend much time thinking about it, but jumped right on the back of one of those innocent animals and away we went galloping north as fast as our legs could carry us. I needn't tell you about the towns that I didn't see nor the villages that I took good care to go around. No! I crossed the ploughed fields; I leaped the hedges; I scrambled over the fences; I dug my heels into my nag; I thrashed him; I fairly lifted the poor fellow off his feet! At last I got to the end of the tilled land. Good! There was the desert. 'That suits me!' said I, 'for I can see better ahead of me and farther too.' I was hoping all the time to see the balloon tacking about and waiting for me. But not a bit of it; and so, in about three hours, I go plump, like a fool, into a camp of Arabs! Whew! what a hunt that was! You see, Mr. Kennedy, a hunter don't know what a real hunt is until he's been hunted himself! Still I advise him not to try it if he can keep out of it! My horse was so tired, he was ready to drop off his legs; they were close on me; I threw myself to the ground; then I jumped up again behind an Arab! I didn't mean the fellow any harm, and I hope he has no grudge against me for choking him, but I saw you—and you know the rest. The Victoria came on at my heels, and you caught me up flying, as a circus-rider does a ring. Wasn't I right in counting on you? Now, doctor, you see how simple all that was! Nothing more natural in the world! I'm ready to begin over again, if it would be of any service to you. And besides, master, as I said a while ago, it's not worth mentioning."

"My noble, gallant Joe!" said the doctor, with great feeling. "Heart of gold! we were not astray in trusting to your intelligence and skill."

"Poh! doctor, one has only just to follow things along as they happen, and he can always work his way out of a scrape! The safest plan, you see, is to take matters as they come."

While Joe was telling his experience, the balloon had rapidly passed over a long reach of country, and Kennedy soon pointed out on the horizon a collection of structures that looked like a town. The doctor glanced at his map and recognized the place as the large village of Tagelei, in the Damerghou country.

"Here," said he, "we come upon Dr. Barth's route. It was at this place that he parted from his companions, Richardson and Overweg; the first was to follow the Zinder route, and the second that of Maradi; and you may remember that, of these three travellers, Barth was the only one who ever returned to Europe."

"Then," said Kennedy, following out on the map the direction of the Victoria, "we are going due north."

"Due north, Dick."

"And don't that give you a little uneasiness?"

"Why should it?"

"Because that line leads to Tripoli, and over the Great Desert."

"Oh, we shall not go so far as that, my friend—at least, I hope not."

"But where do you expect to halt?"

"Come, Dick, don't you feel some curiosity to see Timbuctoo?"

"Timbuctoo?"

"Certainly," said Joe; "nobody nowadays can think of making the trip to Africa without going to see Timbuctoo."

"You will be only the fifth or sixth European who has ever set eyes on that mysterious city."

"Ho, then, for Timbuctoo!"

"Well, then, let us try to get as far as between the seventeenth and eighteenth degrees of north latitude, and there we will seek a favorable wind to carry us westward."

"Good!" said the hunter. "But have we still far to go to the northward?"

"One hundred and fifty miles at least."

"In that case," said Kennedy, "I'll turn in and sleep a bit."

"Sleep, sir; sleep!" urged Joe. "And you, doctor, do the same yourself: you must have need of rest, for I made you keep watch a little out of time."

The sportsman stretched himself under the awning; but Ferguson, who was not easily conquered by fatigue, remained at his post.

In about three hours the Victoria was crossing with extreme rapidity an expanse of stony country, with ranges of lofty, naked mountains of granitic formation at the base. A few isolated peaks attained the height of even four thousand feet. Giraffes, antelopes, and ostriches were seen running and bounding with marvellous agility in the midst of forests of acacias, mimosas, souahs, and date-trees. After the barrenness of the desert, vegetation was now resuming its empire. This was the country of the Kailouas, who veil their faces with a bandage of cotton, like their dangerous neighbors, the Touaregs.

At ten o'clock in the evening, after a splendid trip of two hundred and fifty miles, the Victoria halted over an important town. The moonlight revealed glimpses of one district half in ruins; and some pinnacles of mosques and minarets shot up here and there, glistening in the silvery rays. The doctor took a stellar observation, and discovered that he was in the latitude of Aghades.

This city, once the seat of an immense trade, was already falling into ruin when Dr. Barth visited it.

The Victoria, not being seen in the obscurity of night, descended about two miles above Aghades, in a field of millet. The night was calm, and began to break into dawn about three o'clock A.M.; while a light wind coaxed the balloon westward, and even a little toward the south.

Dr. Ferguson hastened to avail himself of such good fortune, and rapidly ascending resumed his aerial journey amid a long wake of golden morning sunshine.



CHAPTER THIRTY-EIGHTH.

A Rapid Passage.—Prudent Resolves.—Caravans in Sight.—Incessant Rains.— Goa.—The Niger.—Golberry, Geoffroy, and Gray.—Mungo Park.—Laing.— Rene Caillie.—Clapperton.—John and Richard Lander.

The 17th of May passed tranquilly, without any remarkable incident; the desert gained upon them once more; a moderate wind bore the Victoria toward the southwest, and she never swerved to the right or to the left, but her shadow traced a perfectly straight line on the sand.

Before starting, the doctor had prudently renewed his stock of water, having feared that he should not be able to touch ground in these regions, infested as they are by the Aouelim-Minian Touaregs. The plateau, at an elevation of eighteen hundred feet above the level of the sea, sloped down toward the south. Our travellers, having crossed the Aghades route at Murzouk—a route often pressed by the feet of camels—arrived that evening, in the sixteenth degree of north latitude, and four degrees fifty-five minutes east longitude, after having passed over one hundred and eighty miles of a long and monotonous day's journey.

During the day Joe dressed the last pieces of game, which had been only hastily prepared, and he served up for supper a mess of snipe, that were greatly relished. The wind continuing good, the doctor resolved to keep on during the night, the moon, still nearly at the full, illumining it with her radiance. The Victoria ascended to a height of five hundred feet, and, during her nocturnal trip of about sixty miles, the gentle slumbers of an infant would not have been disturbed by her motion.

On Sunday morning, the direction of the wind again changed, and it bore to the northwestward. A few crows were seen sweeping through the air, and, off on the horizon, a flock of vultures which, fortunately, however, kept at a distance.

The sight of these birds led Joe to compliment his master on the idea of having two balloons.

"Where would we be," said he, "with only one balloon? The second balloon is like the life-boat to a ship; in case of wreck we could always take to it and escape."

"You are right, friend Joe," said the doctor, "only that my life-boat gives me some uneasiness. It is not so good as the main craft."

"What do you mean by that, doctor?" asked Kennedy.

"I mean to say that the new Victoria is not so good as the old one. Whether it be that the stuff it is made of is too much worn, or that the heat of the spiral has melted the gutta-percha, I can observe a certain loss of gas. It don't amount to much thus far, but still it is noticeable. We have a tendency to sink, and, in order to keep our elevation, I am compelled to give greater dilation to the hydrogen."

"The deuce!" exclaimed Kennedy with concern; "I see no remedy for that."

"There is none, Dick, and that is why we must hasten our progress, and even avoid night halts."

"Are we still far from the coast?" asked Joe.

"Which coast, my boy? How are we to know whither chance will carry us? All that I can say is, that Timbuctoo is still about four hundred miles to the westward.

"And how long will it take us to get there?"

"Should the wind not carry us too far out of the way, I hope to reach that city by Tuesday evening."

"Then," remarked Joe, pointing to a long file of animals and men winding across the open desert, "we shall arrive there sooner than that caravan."

Ferguson and Kennedy leaned over and saw an immense cavalcade. There were at least one hundred and fifty camels of the kind that, for twelve mutkals of gold, or about twenty-five dollars, go from Timbuctoo to Tafilet with a load of five hundred pounds upon their backs. Each animal had dangling to its tail a bag to receive its excrement, the only fuel on which the caravans can depend when crossing the desert.

These Touareg camels are of the very best race. They can go from three to seven days without drinking, and for two without eating. Their speed surpasses that of the horse, and they obey with intelligence the voice of the khabir, or guide of the caravan. They are known in the country under the name of mehari.

Such were the details given by the doctor while his companions continued to gaze upon that multitude of men, women, and children, advancing on foot and with difficulty over a waste of sand half in motion, and scarcely kept in its place by scanty nettles, withered grass, and stunted bushes that grew upon it. The wind obliterated the marks of their feet almost instantly.

Joe inquired how the Arabs managed to guide themselves across the desert, and come to the few wells scattered far between throughout this vast solitude.

"The Arabs," replied Dr. Ferguson, "are endowed by nature with a wonderful instinct in finding their way. Where a European would be at a loss, they never hesitate for a moment. An insignificant fragment of rock, a pebble, a tuft of grass, a different shade of color in the sand, suffice to guide them with accuracy. During the night they go by the polar star. They never travel more than two miles per hour, and always rest during the noonday heat. You may judge from that how long it takes them to cross Sahara, a desert more than nine hundred miles in breadth."

But the Victoria had already disappeared from the astonished gaze of the Arabs, who must have envied her rapidity. That evening she passed two degrees twenty minutes east longitude, and during the night left another degree behind her.

On Monday the weather changed completely. Rain began to fall with extreme violence, and not only had the balloon to resist the power of this deluge, but also the increase of weight which it caused by wetting the whole machine, car and all. This continuous shower accounted for the swamps and marshes that formed the sole surface of the country. Vegetation reappeared, however, along with the mimosas, the baobabs, and the tamarind-trees.

Such was the Sonray country, with its villages topped with roofs turned over like Armenian caps. There were few mountains, and only such hills as were enough to form the ravines and pools where the pintadoes and snipes went sailing and diving through. Here and there, an impetuous torrent cut the roads, and had to be crossed by the natives on long vines stretched from tree to tree. The forests gave place to jungles, which alligators, hippopotami, and the rhinoceros, made their haunts.

"It will not be long before we see the Niger," said the doctor. "The face of the country always changes in the vicinity of large rivers. These moving highways, as they are sometimes correctly called, have first brought vegetation with them, as they will at last bring civilization. Thus, in its course of twenty-five hundred miles, the Niger has scattered along its banks the most important cities of Africa."

"By-the-way," put in Joe, "that reminds me of what was said by an admirer of the goodness of Providence, who praised the foresight with which it had generally caused rivers to flow close to large cities!"

At noon the Victoria was passing over a petty town, a mere assemblage of miserable huts, which once was Goa, a great capital.

"It was there," said the doctor, "that Barth crossed the Niger, on his return from Timbuctoo. This is the river so famous in antiquity, the rival of the Nile, to which pagan superstition ascribed a celestial origin. Like the Nile, it has engaged the attention of geographers in all ages; and like it, also, its exploration has cost the lives of many victims; yes, even more of them than perished on account of the other."

The Niger flowed broadly between its banks, and its waters rolled southward with some violence of current; but our travellers, borne swiftly by as they were, could scarcely catch a glimpse of its curious outline.

"I wanted to talk to you about this river," said Dr. Ferguson, "and it is already far from us. Under the names of Dhiouleba, Mayo, Egghirreou, Quorra, and other titles besides, it traverses an immense extent of country, and almost competes in length with the Nile. These appellations signify simply 'the River,' according to the dialects of the countries through which it passes."

"Did Dr. Barth follow this route?" asked Kennedy.

"No, Dick: in quitting Lake Tchad, he passed through the different towns of Bornou, and intersected the Niger at Say, four degrees below Goa; then he penetrated to the bosom of those unexplored countries which the Niger embraces in its elbow; and, after eight months of fresh fatigues, he arrived at Timbuctoo; all of which we may do in about three days with as swift a wind as this."

"Have the sources of the Niger been discovered?" asked Joe.

"Long since," replied the doctor. "The exploration of the Niger and its tributaries was the object of several expeditions, the principal of which I shall mention: Between 1749 and 1758, Adamson made a reconnoissance of the river, and visited Gorea; from 1785 to 1788, Golberry and Geoffroy travelled across the deserts of Senegambia, and ascended as far as the country of the Moors, who assassinated Saugnier, Brisson, Adam, Riley, Cochelet, and so many other unfortunate men. Then came the illustrious Mungo Park, the friend of Sir Walter Scott, and, like him, a Scotchman by birth. Sent out in 1795 by the African Society of London, he got as far as Bambarra, saw the Niger, travelled five hundred miles with a slave-merchant, reconnoitred the Gambia River, and returned to England in 1797. He again set out, on the 30th of January, 1805, with his brother-in-law Anderson, Scott, the designer, and a gang of workmen; he reached Gorea, there added a detachment of thirty-five soldiers to his party, and saw the Niger again on the 19th of August. But, by that time, in consequence of fatigue, privations, ill-usage, the inclemencies of the weather, and the unhealthiness of the country, only eleven persons remained alive of the forty Europeans in the party. On the 16th of November, the last letters from Mungo Park reached his wife; and, a year later a trader from that country gave information that, having got as far as Boussa, on the Niger, on the 23d of December, the unfortunate traveller's boat was upset by the cataracts in that part of the river, and he was murdered by the natives."

"And his dreadful fate did not check the efforts of others to explore that river?"

"On the contrary, Dick. Since then, there were two objects in view: namely, to recover the lost man's papers, as well as to pursue the exploration. In 1816, an expedition was organized, in which Major Grey took part. It arrived in Senegal, penetrated to the Fonta-Jallon, visited the Foullah and Mandingo populations, and returned to England without further results. In 1822, Major Laing explored all the western part of Africa near to the British possessions; and he it was who got so far as the sources of the Niger; and, according to his documents, the spring in which that immense river takes its rise is not two feet broad.

"Easy to jump over," said Joe.

"How's that? Easy you think, eh?" retorted the doctor. "If we are to believe tradition, whoever attempts to pass that spring, by leaping over it, is immediately swallowed up; and whoever tries to draw water from it, feels himself repulsed by an invisible hand."

"I suppose a man has a right not to believe a word of that!" persisted Joe.

"Oh, by all means!—Five years later, it was Major Laing's destiny to force his way across the desert of Sahara, penetrate to Timbuctoo, and perish a few miles above it, by strangling, at the hands of the Ouelad-shiman, who wanted to compel him to turn Mussulman."

"Still another victim!" said the sportsman.

"It was then that a brave young man, with his own feeble resources, undertook and accomplished the most astonishing of modern journeys—I mean the Frenchman Rene Caillie, who, after sundry attempts in 1819 and 1824, set out again on the 19th of April, 1827, from Rio Nunez. On the 3d of August he arrived at Time, so thoroughly exhausted and ill that he could not resume his journey until six months later, in January, 1828. He then joined a caravan, and, protected by his Oriental dress, reached the Niger on the 10th of March, penetrated to the city of Jenne, embarked on the river, and descended it, as far as Timbuctoo, where he arrived on the 30th of April. In 1760, another Frenchman, Imbert by name, and, in 1810, an Englishman, Robert Adams, had seen this curious place; but Rene Caillie was to be the first European who could bring back any authentic data concerning it. On the 4th of May he quitted this 'Queen of the desert;' on the 9th, he surveyed the very spot where Major Laing had been murdered; on the 19th, he arrived at El-Arouan, and left that commercial town to brave a thousand dangers in crossing the vast solitudes comprised between the Soudan and the northern regions of Africa. At length he entered Tangiers, and on the 28th of September sailed for Toulon. In nineteen months, notwithstanding one hundred and eighty days' sickness, he had traversed Africa from west to north. Ah! had Callie been born in England, he would have been honored as the most intrepid traveller of modern times, as was the case with Mungo Park. But in France he was not appreciated according to his worth."

"He was a sturdy fellow!" said Kennedy, "but what became of him?"

"He died at the age of thirty-nine, from the consequences of his long fatigues. They thought they had done enough in decreeing him the prize of the Geographical Society in 1828; the highest honors would have been paid to him in England.

"While he was accomplishing this remarkable journey, an Englishman had conceived a similar enterprise and was trying to push it through with equal courage, if not with equal good fortune. This was Captain Clapperton, the companion of Denham. In 1829 he reentered Africa by the western coast of the Gulf of Benin; he then followed in the track of Mungo Park and of Laing, recovered at Boussa the documents relative to the death of the former, and arrived on the 20th of August at Sackatoo, where he was seized and held as a prisoner, until he expired in the arms of his faithful attendant Richard Lander."

"And what became of this Lander?" asked Joe, deeply interested.

"He succeeded in regaining the coast and returned to London, bringing with him the captain's papers, and an exact narrative of his own journey. He then offered his services to the government to complete the reconnoissance of the Niger. He took with him his brother John, the second child of a poor couple in Cornwall, and, together, these men, between 1829 and 1831, redescended the river from Boussa to its mouth, describing it village by village, mile by mile."

"So both the brothers escaped the common fate?" queried Kennedy.

"Yes, on this expedition, at least; but in 1833 Richard undertook a third trip to the Niger, and perished by a bullet, near the mouth of the river. You see, then, my friends, that the country over which we are now passing has witnessed some noble instances of self-sacrifice which, unfortunately, have only too often had death for their reward."



CHAPTER THIRTY-NINTH.

The Country in the Elbow of the Niger.—A Fantastic View of the Hombori Mountains.—Kabra.—Timbuctoo.—The Chart of Dr. Barth. —A Decaying City.—Whither Heaven wills.

During this dull Monday, Dr. Ferguson diverted his thoughts by giving his companions a thousand details concerning the country they were crossing. The surface, which was quite flat, offered no impediment to their progress. The doctor's sole anxiety arose from the obstinate northeast wind which continued to blow furiously, and bore them away from the latitude of Timbuctoo.

The Niger, after running northward as far as that city, sweeps around, like an immense water-jet from some fountain, and falls into the Atlantic in a broad sheaf. In the elbow thus formed the country is of varied character, sometimes luxuriantly fertile, and sometimes extremely bare; fields of maize succeeded by wide spaces covered with broom-corn and uncultivated plains. All kinds of aquatic birds—pelicans, wild-duck, kingfishers, and the rest—were seen in numerous flocks hovering about the borders of the pools and torrents.

From time to time there appeared an encampment of Touaregs, the men sheltered under their leather tents, while their women were busied with the domestic toil outside, milking their camels and smoking their huge-bowled pipes.

By eight o'clock in the evening the Victoria had advanced more than two hundred miles to the westward, and our aeronauts became the spectators of a magnificent scene.

A mass of moonbeams forcing their way through an opening in the clouds, and gliding between the long lines of falling rain, descended in a golden shower on the ridges of the Hombori Mountains. Nothing could be more weird than the appearance of these seemingly basaltic summits; they stood out in fantastic profile against the sombre sky, and the beholder might have fancied them to be the legendary ruins of some vast city of the middle ages, such as the icebergs of the polar seas sometimes mimic them in nights of gloom.

"An admirable landscape for the 'Mysteries of Udolpho'!" exclaimed the doctor. "Ann Radcliffe could not have depicted yon mountains in a more appalling aspect."

"Faith!" said Joe, "I wouldn't like to be strolling alone in the evening through this country of ghosts. Do you see now, master, if it wasn't so heavy, I'd like to carry that whole landscape home to Scotland! It would do for the borders of Loch Lomond, and tourists would rush there in crowds."

"Our balloon is hardly large enough to admit of that little experiment—but I think our direction is changing. Bravo!—the elves and fairies of the place are quite obliging. See, they've sent us a nice little southeast breeze, that will put us on the right track again."

In fact, the Victoria was resuming a more northerly route, and on the morning of the 20th she was passing over an inextricable network of channels, torrents, and streams, in fine, the whole complicated tangle of the Niger's tributaries. Many of these channels, covered with a thick growth of herbage, resembled luxuriant meadow-lands. There the doctor recognized the route followed by the explorer Barth when he launched upon the river to descend to Timbuctoo. Eight hundred fathoms broad at this point, the Niger flowed between banks richly grown with cruciferous plants and tamarind-trees. Herds of agile gazelles were seen skipping about, their curling horns mingling with the tall herbage, within which the alligator, half concealed, lay silently in wait for them with watchful eyes.

Long files of camels and asses laden with merchandise from Jenne were winding in under the noble trees. Ere long, an amphitheatre of low-built houses was discovered at a turn of the river, their roofs and terraces heaped up with hay and straw gathered from the neighboring districts.

"There's Kabra!" exclaimed the doctor, joyously; "there is the harbor of Timbuctoo, and the city is not five miles from here!"

"Then, sir, you are satisfied?" half queried Joe.

"Delighted, my boy!"

"Very good; then every thing's for the best!"

In fact, about two o'clock, the Queen of the Desert, mysterious Timbuctoo, which once, like Athens and Rome, had her schools of learned men, and her professorships of philosophy, stretched away before the gaze of our travellers.

Ferguson followed the most minute details upon the chart traced by Barth himself, and was enabled to recognize its perfect accuracy.

The city forms an immense triangle marked out upon a vast plain of white sand, its acute angle directed toward the north and piercing a corner of the desert. In the environs there was almost nothing, hardly even a few grasses, with some dwarf mimosas and stunted bushes.

As for the appearance of Timbuctoo, the reader has but to imagine a collection of billiard-balls and thimbles—such is the bird's-eye view! The streets, which are quite narrow, are lined with houses only one story in height, built of bricks dried in the sun, and huts of straw and reeds, the former square, the latter conical. Upon the terraces were seen some of the male inhabitants, carelessly lounging at full length in flowing apparel of bright colors, and lance or musket in hand; but no women were visible at that hour of the day.

"Yet they are said to be handsome," remarked the doctor. "You see the three towers of the three mosques that are the only ones left standing of a great number— the city has indeed fallen from its ancient splendor! At the top of the triangle rises the Mosque of Sankore, with its ranges of galleries resting on arcades of sufficiently pure design. Farther on, and near to the Sane-Gungu quarter, is the Mosque of Sidi-Yahia and some two-story houses. But do not look for either palaces or monuments: the sheik is a mere son of traffic, and his royal palace is a counting-house."

"It seems to me that I can see half-ruined ramparts," said Kennedy.

"They were destroyed by the Fouillanes in 1826; the city was one-third larger then, for Timbuctoo, an object generally coveted by all the tribes, since the eleventh century, has belonged in succession to the Touaregs, the Sonrayans, the Morocco men, and the Fouillanes; and this great centre of civilization, where a sage like Ahmed-Baba owned, in the sixteenth century, a library of sixteen hundred manuscripts, is now nothing but a mere half-way house for the trade of Central Africa."

The city, indeed, seemed abandoned to supreme neglect; it betrayed that indifference which seems epidemic to cities that are passing away. Huge heaps of rubbish encumbered the suburbs, and, with the hill on which the market-place stood, formed the only inequalities of the ground.

When the Victoria passed, there was some slight show of movement; drums were beaten; but the last learned man still lingering in the place had hardly time to notice the new phenomenon, for our travellers, driven onward by the wind of the desert, resumed the winding course of the river, and, ere long, Timbuctoo was nothing more than one of the fleeting reminiscences of their journey.

"And now," said the doctor, "Heaven may waft us whither it pleases!"

"Provided only that we go westward," added Kennedy.

"Bah!" said Joe; "I wouldn't be afraid if it was to go back to Zanzibar by the same road, or to cross the ocean to America."

"We would first have to be able to do that, Joe!"

"And what's wanting, doctor?"

"Gas, my boy; the ascending force of the balloon is evidently growing weaker, and we shall need all our management to make it carry us to the sea-coast. I shall even have to throw over some ballast. We are too heavy."

"That's what comes of doing nothing, doctor; when a man lies stretched out all day long in his hammock, he gets fat and heavy. It's a lazybones trip, this of ours, master, and when we get back every body will find us big and stout."

"Just like Joe," said Kennedy; "just the ideas for him: but wait a bit! Can you tell what we may have to go through yet? We are still far from the end of our trip. Where do you expect to strike the African coast, doctor?"

"I should find it hard to answer you, Kennedy. We are at the mercy of very variable winds; but I should think myself fortunate were we to strike it between Sierra Leone and Portendick. There is a stretch of country in that quarter where we should meet with friends."

"And it would be a pleasure to press their hands; but, are we going in the desirable direction?"

"Not any too well, Dick; not any too well! Look at the needle of the compass; we are bearing southward, and ascending the Niger toward its sources."

"A fine chance to discover them," said Joe, "if they were not known already. Now, couldn't we just find others for it, on a pinch?"

"Not exactly, Joe; but don't be alarmed: I hardly expect to go so far as that."

At nightfall the doctor threw out the last bags of sand. The Victoria rose higher, and the blow-pipe, although working at full blast, could scarcely keep her up. At that time she was sixty miles to the southward of Timbuctoo, and in the morning the aeronauts awoke over the banks of the Niger, not far from Lake Debo.



CHAPTER FORTIETH.

Dr. Ferguson's Anxieties.—Persistent Movement southward.—A Cloud of Grasshoppers.—A View of Jenne.—A View of Sego.—Change of the Wind.—Joe's Regrets.

The flow of the river was, at that point, divided by large islands into narrow branches, with a very rapid current. Upon one among them stood some shepherds' huts, but it had become impossible to take an exact observation of them, because the speed of the balloon was constantly increasing. Unfortunately, it turned still more toward the south, and in a few moments crossed Lake Debo.

Dr. Ferguson, forcing the dilation of his aerial craft to the utmost, sought for other currents of air at different heights, but in vain; and he soon gave up the attempt, which was only augmenting the waste of gas by pressing it against the well-worn tissue of the balloon.

He made no remark, but he began to feel very anxious. This persistence of the wind to head him off toward the southern part of Africa was defeating his calculations, and he no longer knew upon whom or upon what to depend. Should he not reach the English or French territories, what was to become of him in the midst of the barbarous tribes that infest the coasts of Guinea? How should he there get to a ship to take him back to England? And the actual direction of the wind was driving him along to the kingdom of Dahomey, among the most savage races, and into the power of a ruler who was in the habit of sacrificing thousands of human victims at his public orgies. There he would be lost!

On the other hand, the balloon was visibly wearing out, and the doctor felt it failing him. However, as the weather was clearing up a little, he hoped that the cessation of the rain would bring about a change in the atmospheric currents.

It was therefore a disagreeable reminder of the actual situation when Joe said aloud:

"There! the rain's going to pour down harder than ever; and this time it will be the deluge itself, if we're to judge by yon cloud that's coming up!"

"What! another cloud?" asked Ferguson.

"Yes, and a famous one," replied Kennedy.

"I never saw the like of it," added Joe.

"I breathe freely again!" said the doctor, laying down his spy-glass. "That's not a cloud!"

"Not a cloud?" queried Joe, with surprise.

"No; it is a swarm."

"Eh?"

"A swarm of grasshoppers!"

"That? Grasshoppers!"

"Myriads of grasshoppers, that are going to sweep over this country like a water-spout; and woe to it! for, should these insects alight, it will be laid waste."

"That would be a sight worth beholding!"

"Wait a little, Joe. In ten minutes that cloud will have arrived where we are, and you can then judge by the aid of your own eyes."

The doctor was right. The cloud, thick, opaque, and several miles in extent, came on with a deafening noise, casting its immense shadow over the fields. It was composed of numberless legions of that species of grasshopper called crickets. About a hundred paces from the balloon, they settled down upon a tract full of foliage and verdure. Fifteen minutes later, the mass resumed its flight, and our travellers could, even at a distance, see the trees and the bushes entirely stripped, and the fields as bare as though they had been swept with the scythe. One would have thought that a sudden winter had just descended upon the earth and struck the region with the most complete sterility.

"Well, Joe, what do you think of that?"

"Well, doctor, it's very curious, but quite natural. What one grasshopper does on a small scale, thousands do on a grand scale."

"It's a terrible shower," said the hunter; "more so than hail itself in the devastation it causes."

"It is impossible to prevent it," replied Ferguson. "Sometimes the inhabitants have had the idea to burn the forests, and even the standing crops, in order to arrest the progress of these insects; but the first ranks plunging into the flames would extinguish them beneath their mass, and the rest of the swarm would then pass irresistibly onward. Fortunately, in these regions, there is some sort of compensation for their ravages, since the natives gather these insects in great numbers and greedily eat them."

"They are the prawns of the air," said Joe, who added that he was sorry that he had never had the chance to taste them—just for information's sake!

The country became more marshy toward evening; the forests dwindled to isolated clumps of trees; and on the borders of the river could be seen plantations of tobacco, and swampy meadow-lands fat with forage. At last the city of Jenne, on a large island, came in sight, with the two towers of its clay-built mosque, and the putrid odor of the millions of swallows' nests accumulated in its walls. The tops of some baobabs, mimosas, and date-trees peeped up between the houses; and, even at night, the activity of the place seemed very great. Jenne is, in fact, quite a commercial city: it supplies all the wants of Timbuctoo. Its boats on the river, and its caravans along the shaded roads, bear thither the various products of its industry.

"Were it not that to do so would prolong our journey," said the doctor, "I should like to alight at this place. There must be more than one Arab there who has travelled in England and France, and to whom our style of locomotion is not altogether new. But it would not be prudent."

"Let us put off the visit until our next trip," said Joe, laughing.

"Besides, my friends, unless I am mistaken, the wind has a slight tendency to veer a little more to the eastward, and we must not lose such an opportunity."

The doctor threw overboard some articles that were no longer of use—some empty bottles, and a case that had contained preserved-meat—and thereby managed to keep the balloon in a belt of the atmosphere more favorable to his plans. At four o'clock in the morning the first rays of the sun lighted up Sego, the capital of Bambarra, which could be recognized at once by the four towns that compose it, by its Saracenic mosques, and by the incessant going and coming of the flat-bottomed boats that convey its inhabitants from one quarter to the other. But the travellers were not more seen than they saw. They sped rapidly and directly to the northwest, and the doctor's anxiety gradually subsided.

"Two more days in this direction, and at this rate of speed, and we'll reach the Senegal River."

"And we'll be in a friendly country?" asked the hunter.

"Not altogether; but, if the worst came to the worst, and the balloon were to fail us, we might make our way to the French settlements. But, let it hold out only for a few hundred miles, and we shall arrive without fatigue, alarm, or danger, at the western coast."

"And the thing will be over!" added Joe. "Heigh-ho! so much the worse. If it wasn't for the pleasure of telling about it, I would never want to set foot on the ground again! Do you think anybody will believe our story, doctor?"

"Who can tell, Joe? One thing, however, will be undeniable: a thousand witnesses saw us start on one side of the African Continent, and a thousand more will see us arrive on the other."

"And, in that case, it seems to me that it would be hard to say that we had not crossed it," added Kennedy.

"Ah, doctor!" said Joe again, with a deep sigh, "I'll think more than once of my lumps of solid gold-ore! There was something that would have given WEIGHT to our narrative! At a grain of gold per head, I could have got together a nice crowd to listen to me, and even to admire me!"



CHAPTER FORTY-FIRST.

The Approaches to Senegal.—The Balloon sinks lower and lower.—They keep throwing out, throwing out.—The Marabout Al-Hadji.—Messrs. Pascal, Vincent, and Lambert.—A Rival of Mohammed.—The Difficult Mountains.—Kennedy's Weapons.—One of Joe's Manoeuvres.—A Halt over a Forest.

On the 27th of May, at nine o'clock in the morning, the country presented an entirely different aspect. The slopes, extending far away, changed to hills that gave evidence of mountains soon to follow. They would have to cross the chain which separates the basin of the Niger from the basin of the Senegal, and determines the course of the water-shed, whether to the Gulf of Guinea on the one hand, or to the bay of Cape Verde on the other.

As far as Senegal, this part of Africa is marked down as dangerous. Dr. Ferguson knew it through the recitals of his predecessors. They had suffered a thousand privations and been exposed to a thousand dangers in the midst of these barbarous negro tribes. It was this fatal climate that had devoured most of the companions of Mungo Park. Ferguson, therefore, was more than ever decided not to set foot in this inhospitable region.

But he had not enjoyed one moment of repose. The Victoria was descending very perceptibly, so much so that he had to throw overboard a number more of useless articles, especially when there was a mountain-top to pass. Things went on thus for more than one hundred and twenty miles; they were worn out with ascending and falling again; the balloon, like another rock of Sisyphus, kept continually sinking back toward the ground. The rotundity of the covering, which was now but little inflated, was collapsing already. It assumed an elongated shape, and the wind hollowed large cavities in the silken surface.

Kennedy could not help observing this.

"Is there a crack or a tear in the balloon?" he asked.

"No, but the gutta percha has evidently softened or melted in the heat, and the hydrogen is escaping through the silk."

"How can we prevent that?"

"It is impossible. Let us lighten her. That is the only help. So let us throw out every thing we can spare."

"But what shall it be?" said the hunter, looking at the car, which was already quite bare.

"Well, let us get rid of the awning, for its weight is quite considerable."

Joe, who was interested in this order, climbed up on the circle which kept together the cordage of the network, and from that place easily managed to detach the heavy curtains of the awning and throw them overboard.

"There's something that will gladden the hearts of a whole tribe of blacks," said he; "there's enough to dress a thousand of them, for they're not very extravagant with cloth."

The balloon had risen a little, but it soon became evident that it was again approaching the ground.

"Let us alight," suggested Kennedy, "and see what can be done with the covering of the balloon."

"I tell you, again, Dick, that we have no means of repairing it."

"Then what shall we do?"

"We'll have to sacrifice every thing not absolutely indispensable; I am anxious, at all hazards, to avoid a detention in these regions. The forests over the tops of which we are skimming are any thing but safe."

"What! are there lions in them, or hyenas?" asked Joe, with an expression of sovereign contempt.

"Worse than that, my boy! There are men, and some of the most cruel, too, in all Africa."

"How is that known?"

"By the statements of travellers who have been here before us. Then the French settlers, who occupy the colony of Senegal, necessarily have relations with the surrounding tribes. Under the administration of Colonel Faidherbe, reconnoissances have been pushed far up into the country. Officers such as Messrs. Pascal, Vincent, and Lambert, have brought back precious documents from their expeditions. They have explored these countries formed by the elbow of the Senegal in places where war and pillage have left nothing but ruins."

"What, then, took place?"

"I will tell you. In 1854 a Marabout of the Senegalese Fouta, Al-Hadji by name, declaring himself to be inspired like Mohammed, stirred up all the tribes to war against the infidels—that is to say, against the Europeans. He carried destruction and desolation over the regions between the Senegal River and its tributary, the Fateme. Three hordes of fanatics led on by him scoured the country, sparing neither a village nor a hut in their pillaging, massacring career. He advanced in person on the town of Sego, which was a long time threatened. In 1857 he worked up farther to the northward, and invested the fortification of Medina, built by the French on the bank of the river. This stronghold was defended by Paul Holl, who, for several months, without provisions or ammunition, held out until Colonel Faidherbe came to his relief. Al-Hadji and his bands then repassed the Senegal, and reappeared in the Kaarta, continuing their rapine and murder.—Well, here below us is the very country in which he has found refuge with his hordes of banditti; and I assure you that it would not be a good thing to fall into his hands."

"We shall not," said Joe, "even if we have to throw overboard our clothes to save the Victoria."

"We are not far from the river," said the doctor, "but I foresee that our balloon will not be able to carry us beyond it."

"Let us reach its banks, at all events," said the Scot, "and that will be so much gained."

"That is what we are trying to do," rejoined Ferguson, "only that one thing makes me feel anxious."

"What is that?"

"We shall have mountains to pass, and that will be difficult to do, since I cannot augment the ascensional force of the balloon, even with the greatest possible heat that I can produce."

"Well, wait a bit," said Kennedy, "and we shall see!"

"The poor Victoria!" sighed Joe; "I had got fond of her as the sailor does of his ship, and I'll not give her up so easily. She may not be what she was at the start— granted; but we shouldn't say a word against her. She has done us good service, and it would break my heart to desert her."

"Be at your ease, Joe; if we leave her, it will be in spite of ourselves. She'll serve us until she's completely worn out, and I ask of her only twenty-four hours more!"

"Ah, she's getting used up! She grows thinner and thinner," said Joe, dolefully, while he eyed her. "Poor balloon!"

"Unless I am deceived," said Kennedy, "there on the horizon are the mountains of which you were speaking, doctor."

"Yes, there they are, indeed!" exclaimed the doctor, after having examined them through his spy-glass, "and they look very high. We shall have some trouble in crossing them."

"Can we not avoid them?"

"I am afraid not, Dick. See what an immense space they occupy—nearly one-half of the horizon!"

"They even seem to shut us in," added Joe. "They are gaining on both our right and our left."

"We must then pass over them."

These obstacles, which threatened such imminent peril, seemed to approach with extreme rapidity, or, to speak more accurately, the wind, which was very fresh, was hurrying the balloon toward the sharp peaks. So rise it must, or be dashed to pieces.

"Let us empty our tank of water," said the doctor, "and keep only enough for one day."

"There it goes," shouted Joe.

"Does the balloon rise at all?" asked Kennedy.

"A little—some fifty feet," replied the doctor, who kept his eyes fixed on the barometer. "But that is not enough."

In truth the lofty peaks were starting up so swiftly before the travellers that they seemed to be rushing down upon them. The balloon was far from rising above them. She lacked an elevation of more than five hundred feet more.

The stock of water for the cylinder was also thrown overboard and only a few pints were retained, but still all this was not enough.

"We must pass them though!" urged the doctor.

"Let us throw out the tanks—we have emptied them." said Kennedy.

"Over with them!"

"There they go!" panted Joe. "But it's hard to see ourselves dropping off this way by piecemeal."

"Now, for your part, Joe, make no attempt to sacrifice yourself as you did the other day! Whatever happens, swear to me that you will not leave us!"

"Have no fears, my master, we shall not be separated."

The Victoria had ascended some hundred and twenty feet, but the crest of the mountain still towered above it. It was an almost perpendicular ridge that ended in a regular wall rising abruptly in a straight line. It still rose more than two hundred feet over the aeronauts.

"In ten minutes," said the doctor to himself, "our car will be dashed against those rocks unless we succeed in passing them!"

"Well, doctor?" queried Joe.

"Keep nothing but our pemmican, and throw out all the heavy meat."

Thereupon the balloon was again lightened by some fifty pounds, and it rose very perceptibly, but that was of little consequence, unless it got above the line of the mountain-tops. The situation was terrifying. The Victoria was rushing on with great rapidity. They could feel that she would be dashed to pieces—that the shock would be fearful.

The doctor glanced around him in the car. It was nearly empty.

"If needs be, Dick, hold yourself in readiness to throw over your fire-arms!"

"Sacrifice my fire-arms?" repeated the sportsman, with intense feeling.

"My friend, I ask it; it will be absolutely necessary!"

"Samuel! Doctor!"

"Your guns, and your stock of powder and ball might cost us our lives."

"We are close to it!" cried Joe.

Sixty feet! The mountain still overtopped the balloon by sixty feet.

Joe took the blankets and other coverings and tossed them out; then, without a word to Kennedy, he threw over several bags of bullets and lead.

The balloon went up still higher; it surmounted the dangerous ridge, and the rays of the sun shone upon its uppermost extremity; but the car was still below the level of certain broken masses of rock, against which it would inevitably be dashed.

"Kennedy! Kennedy! throw out your fire-arms, or we are lost!" shouted the doctor.

"Wait, sir; wait one moment!" they heard Joe exclaim, and, looking around, they saw Joe disappear over the edge of the balloon.

"Joe! Joe!" cried Kennedy.

"Wretched man!" was the doctor's agonized expression.

The flat top of the mountain may have had about twenty feet in breadth at this point, and, on the other side, the slope presented a less declivity. The car just touched the level of this plane, which happened to be quite even, and it glided over a soil composed of sharp pebbles that grated as it passed.

"We're over it! we're over it! we're clear!" cried out an exulting voice that made Ferguson's heart leap to his throat.

The daring fellow was there, grasping the lower rim of the car, and running afoot over the top of the mountain, thus lightening the balloon of his whole weight. He had to hold on with all his strength, too, for it was likely to escape his grasp at any moment.

When he had reached the opposite declivity, and the abyss was before him, Joe, by a vigorous effort, hoisted himself from the ground, and, clambering up by the cordage, rejoined his friends.

"That was all!" he coolly ejaculated.

"My brave Joe! my friend!" said the doctor, with deep emotion.

"Oh! what I did," laughed the other, "was not for you; it was to save Mr. Kennedy's rifle. I owed him that good turn for the affair with the Arab! I like to pay my debts, and now we are even," added he, handing to the sportsman his favorite weapon. "I'd feel very badly to see you deprived of it."

Kennedy heartily shook the brave fellow's hand, without being able to utter a word.

The Victoria had nothing to do now but to descend. That was easy enough, so that she was soon at a height of only two hundred feet from the ground, and was then in equilibrium. The surface seemed very much broken as though by a convulsion of nature. It presented numerous inequalities, which would have been very difficult to avoid during the night with a balloon that could no longer be controlled. Evening was coming on rapidly, and, notwithstanding his repugnance, the doctor had to make up his mind to halt until morning.

"We'll now look for a favorable stopping-place," said he.

"Ah!" replied Kennedy, "you have made up your mind, then, at last?"

"Yes, I have for a long time been thinking over a plan which we'll try to put into execution; it is only six o'clock in the evening, and we shall have time enough. Throw out your anchors, Joe!"

Joe immediately obeyed, and the two anchors dangled below the balloon.

"I see large forests ahead of us," said the doctor; "we are going to sweep along their tops, and we shall grapple to some tree, for nothing would make me think of passing the night below, on the ground."

"But can we not descend?" asked Kennedy.

"To what purpose? I repeat that it would be dangerous for us to separate, and, besides, I claim your help for a difficult piece of work."

The Victoria, which was skimming along the tops of immense forests, soon came to a sharp halt. Her anchors had caught, and, the wind falling as dusk came on, she remained motionlessly suspended above a vast field of verdure, formed by the tops of a forest of sycamores.



CHAPTER FORTY-SECOND.

A Struggle of Generosity.—The Last Sacrifice.—The Dilating Apparatus. —Joe's Adroitness.—Midnight.—The Doctor's Watch.—Kennedy's Watch. —The Latter falls asleep at his Post.—The Fire.—The Howlings of the Natives.—Out of Range.

Doctor Ferguson's first care was to take his bearings by stellar observation, and he discovered that he was scarcely twenty-five miles from Senegal.

"All that we can manage to do, my friends," said he, after having pointed his map, "is to cross the river; but, as there is neither bridge nor boat, we must, at all hazards, cross it with the balloon, and, in order to do that, we must still lighten up."

"But I don't exactly see how we can do that?" replied Kennedy, anxious about his fire-arms, "unless one of us makes up his mind to sacrifice himself for the rest,—that is, to stay behind, and, in my turn, I claim that honor."

"You, indeed!" remonstrated Joe; "ain't I used to—"

"The question now is, not to throw ourselves out of the car, but simply to reach the coast of Africa on foot. I am a first-rate walker, a good sportsman, and—"

"I'll never consent to it!" insisted Joe.

"Your generous rivalry is useless, my brave friends," said Ferguson; "I trust that we shall not come to any such extremity: besides, if we did, instead of separating, we should keep together, so as to make our way across the country in company."

"That's the talk," said Joe; "a little tramp won't do us any harm."

"But before we try that," resumed the doctor, "we must employ a last means of lightening the balloon."

"What will that be? I should like to see it," said Kennedy, incredulously.

"We must get rid of the cylinder-chests, the spiral, and the Buntzen battery. Nine hundred pounds make a rather heavy load to carry through the air."

"But then, Samuel, how will you dilate your gas?"

"I shall not do so at all. We'll have to get along without it."

"But—"

"Listen, my friends: I have calculated very exactly the amount of ascensional force left to us, and it is sufficient to carry us every one with the few objects that remain. We shall make in all a weight of hardly five hundred pounds, including the two anchors which I desire to keep."

"Dear doctor, you know more about the matter than we do; you are the sole judge of the situation. Tell us what we ought to do, and we will do it."

"I am at your orders, master," added Joe.

"I repeat, my friends, that however serious the decision may appear, we must sacrifice our apparatus."

"Let it go, then!" said Kennedy, promptly.

"To work!" said Joe.

It was no easy job. The apparatus had to be taken down piece by piece. First, they took out the mixing reservoir, then the one belonging to the cylinder, and lastly the tank in which the decomposition of the water was effected. The united strength of all three travellers was required to detach these reservoirs from the bottom of the car in which they had been so firmly secured; but Kennedy was so strong, Joe so adroit, and the doctor so ingenious, that they finally succeeded. The different pieces were thrown out, one after the other, and they disappeared below, making huge gaps in the foliage of the sycamores.

"The black fellows will be mightily astonished," said Joe, "at finding things like those in the woods; they'll make idols of them!"

The next thing to be looked after was the displacement of the pipes that were fastened in the balloon and connected with the spiral. Joe succeeded in cutting the caoutchouc jointings above the car, but when he came to the pipes he found it more difficult to disengage them, because they were held by their upper extremity and fastened by wires to the very circlet of the valve.

Then it was that Joe showed wonderful adroitness. In his naked feet, so as not to scratch the covering, he succeeded by the aid of the network, and in spite of the oscillations of the balloon, in climbing to the upper extremity, and after a thousand difficulties, in holding on with one hand to that slippery surface, while he detached the outside screws that secured the pipes in their place. These were then easily taken out, and drawn away by the lower end, which was hermetically sealed by means of a strong ligature.

The Victoria, relieved of this considerable weight, rose upright in the air and tugged strongly at the anchor-rope.

About midnight this work ended without accident, but at the cost of most severe exertion, and the trio partook of a luncheon of pemmican and cold punch, as the doctor had no more fire to place at Joe's disposal.

Besides, the latter and Kennedy were dropping off their feet with fatigue.

"Lie down, my friends, and get some rest," said the doctor. "I'll take the first watch; at two o'clock I'll waken Kennedy; at four, Kennedy will waken Joe, and at six we'll start; and may Heaven have us in its keeping for this last day of the trip!"

Without waiting to be coaxed, the doctor's two companions stretched themselves at the bottom of the car and dropped into profound slumber on the instant.

The night was calm. A few clouds broke against the last quarter of the moon, whose uncertain rays scarcely pierced the darkness. Ferguson, resting his elbows on the rim of the car, gazed attentively around him. He watched with close attention the dark screen of foliage that spread beneath him, hiding the ground from his view. The least noise aroused his suspicions, and he questioned even the slightest rustling of the leaves.

He was in that mood which solitude makes more keenly felt, and during which vague terrors mount to the brain. At the close of such a journey, after having surmounted so many obstacles, and at the moment of touching the goal, one's fears are more vivid, one's emotions keener. The point of arrival seems to fly farther from our gaze.

Moreover, the present situation had nothing very consolatory about it. They were in the midst of a barbarous country, and dependent upon a vehicle that might fail them at any moment. The doctor no longer counted implicitly on his balloon; the time had gone by when he manoevred it boldly because he felt sure of it.

Under the influence of these impressions, the doctor, from time to time, thought that he heard vague sounds in the vast forests around him; he even fancied that he saw a swift gleam of fire shining between the trees. He looked sharply and turned his night-glass toward the spot; but there was nothing to be seen, and the profoundest silence appeared to return.

He had, no doubt, been under the dominion of a mere hallucination. He continued to listen, but without hearing the slightest noise. When his watch had expired, he woke Kennedy, and, enjoining upon him to observe the extremest vigilance, took his place beside Joe, and fell sound asleep.

Kennedy, while still rubbing his eyes, which he could scarcely keep open, calmly lit his pipe. He then ensconced himself in a corner, and began to smoke vigorously by way of keeping awake.

The most absolute silence reigned around him; a light wind shook the tree-tops and gently rocked the car, inviting the hunter to taste the sleep that stole over him in spite of himself. He strove hard to resist it, and repeatedly opened his eyes to plunge into the outer darkness one of those looks that see nothing; but at last, yielding to fatigue, he sank back and slumbered.

How long he had been buried in this stupor he knew not, but he was suddenly aroused from it by a strange, unexpected crackling sound.

He rubbed his eyes and sprang to his feet. An intense glare half-blinded him and heated his cheek—the forest was in flames!

"Fire! fire!" he shouted, scarcely comprehending what had happened.

His two companions started up in alarm.

"What's the matter?" was the doctor's immediate exclamation.

"Fire!" said Joe. "But who could—"

At this moment loud yells were heard under the foliage, which was now illuminated as brightly as the day.

"Ah! the savages!" cried Joe again; "they have set fire to the forest so as to be the more certain of burning us up."

"The Talabas! Al-Hadji's marabouts, no doubt," said the doctor.

A circle of fire hemmed the Victoria in; the crackling of the dry wood mingled with the hissing and sputtering of the green branches; the clambering vines, the foliage, all the living part of this vegetation, writhed in the destructive element. The eye took in nothing but one vast ocean of flame; the large trees stood forth in black relief in this huge furnace, their branches covered with glowing coals, while the whole blazing mass, the entire conflagration, was reflected on the clouds, and the travellers could fancy themselves enveloped in a hollow globe of fire.

"Let us escape to the ground!" shouted Kennedy, "it is our only chance of safety!"

But Ferguson checked him with a firm grasp, and, dashing at the anchor-rope, severed it with one well-directed blow of his hatchet. Meanwhile, the flames, leaping up at the balloon, already quivered on its illuminated sides; but the Victoria, released from her fastenings, spun upward a thousand feet into the air.

Frightful yells resounded through the forest, along with the report of fire-arms, while the balloon, caught in a current of air that rose with the dawn of day, was borne to the westward.

It was now four o'clock in the morning.



CHAPTER FORTY-THIRD.

The Talabas.—The Pursuit.—A Devastated Country.—The Wind begins to fall.—The Victoria sinks.—The last of the Provisions.—The Leaps of the Balloon.—A Defence with Fire-arms.—The Wind freshens.—The Senegal River.—The Cataracts of Gouina.—The Hot Air.—The Passage of the River.

"Had we not taken the precaution to lighten the balloon yesterday evening, we should have been lost beyond redemption," said the doctor, after a long silence.

"See what's gained by doing things at the right time!" replied Joe. "One gets out of scrapes then, and nothing is more natural."

"We are not out of danger yet," said the doctor.

"What do you still apprehend?" queried Kennedy. "The balloon can't descend without your permission, and even were it to do so—"

"Were it to do so, Dick? Look!"

They had just passed the borders of the forest, and the three friends could see some thirty mounted men clad in broad pantaloons and the floating bournouses. They were armed, some with lances, and others with long muskets, and they were following, on their quick, fiery little steeds, the direction of the balloon, which was moving at only moderate speed.

When they caught sight of the aeronauts, they uttered savage cries, and brandished their weapons. Anger and menace could be read upon their swarthy faces, made more ferocious by thin but bristling beards. Meanwhile they galloped along without difficulty over the low levels and gentle declivities that lead down to the Senegal.

"It is, indeed, they!" said the doctor; "the cruel Talabas! the ferocious marabouts of Al-Hadji! I would rather find myself in the middle of the forest encircled by wild beasts than fall into the hands of these banditti."

"They haven't a very obliging look!" assented Kennedy; "and they are rough, stalwart fellows."

"Happily those brutes can't fly," remarked Joe; "and that's something."

"See," said Ferguson, "those villages in ruins, those huts burned down—that is their work! Where vast stretches of cultivated land were once seen, they have brought barrenness and devastation."

"At all events, however," interposed Kennedy, "they can't overtake us; and, if we succeed in putting the river between us and them, we are safe."

"Perfectly, Dick," replied Ferguson; "but we must not fall to the ground!" and, as he said this, he glanced at the barometer.

"In any case, Joe," added Kennedy, "it would do us no harm to look to our fire-arms."

"No harm in the world, Mr. Dick! We are lucky that we didn't scatter them along the road."

"My rifle!" said the sportsman. "I hope that I shall never be separated from it!"

And so saying, Kennedy loaded the pet piece with the greatest care, for he had plenty of powder and ball remaining.

"At what height are we?" he asked the doctor.

"About seven hundred and fifty feet; but we no longer have the power of seeking favorable currents, either going up or coming down. We are at the mercy of the balloon!"

"That is vexatious!" rejoined Kennedy. "The wind is poor; but if we had come across a hurricane like some of those we met before, these vile brigands would have been out of sight long ago."

"The rascals follow us at their leisure," said Joe. "They're only at a short gallop. Quite a nice little ride!"

"If we were within range," sighed the sportsman, "I should amuse myself with dismounting a few of them."

"Exactly," said the doctor; "but then they would have you within range also, and our balloon would offer only too plain a target to the bullets from their long guns; and, if they were to make a hole in it, I leave you to judge what our situation would be!"

The pursuit of the Talabas continued all morning; and by eleven o'clock the aeronauts had made scarcely fifteen miles to the westward.

The doctor was anxiously watching for the least cloud on the horizon. He feared, above all things, a change in the atmosphere. Should he be thrown back toward the Niger, what would become of him? Besides, he remarked that the balloon tended to fall considerably. Since the start, he had already lost more than three hundred feet, and the Senegal must be about a dozen miles distant. At his present rate of speed, he could count upon travelling only three hours longer.

At this moment his attention was attracted by fresh cries. The Talabas appeared to be much excited, and were spurring their horses.
