"But, we'll come back again, doctor!"
"Come back, Dick? Yes, if we have to abandon the balloon! if we should be forced to return to Lake Tchad on foot, and put ourselves in communication with the Sultan of Bornou! The Arabs cannot have retained a disagreeable remembrance of the first Europeans."
"I will follow you, doctor," replied the hunter, with emphasis. "You may count upon me! We would rather give up the idea of prosecuting this journey than not return. Joe forgot himself for our sake; we will sacrifice ourselves for his!"
This resolve revived some hope in the hearts of these two men; they felt strong in the same inspiration. Ferguson forthwith set every thing at work to get into a contrary current, that might bring him back again to Lake Tchad; but this was impracticable at that moment, and even to alight was out of the question on ground completely bare of trees, and with such a hurricane blowing.
The Victoria thus passed over the country of the Tibbous, crossed the Belad el Djerid, a desert of briers that forms the border of the Soudan, and advanced into the desert of sand streaked with the long tracks of the many caravans that pass and repass there. The last line of vegetation was speedily lost in the dim southern horizon, not far from the principal oasis in this part of Africa, whose fifty wells are shaded by magnificent trees; but it was impossible to stop. An Arab encampment, tents of striped stuff, some camels, stretching out their viper-like heads and necks along the sand, gave life to this solitude, but the Victoria sped by like a shooting-star, and in this way traversed a distance of sixty miles in three hours, without Ferguson being able to check or guide her course.
"We cannot halt, we cannot alight!" said the doctor; "not a tree, not an inequality of the ground! Are we then to be driven clear across Sahara? Surely, Heaven is indeed against us!"
He was uttering these words with a sort of despairing rage, when suddenly he saw the desert sands rising aloft in the midst of a dense cloud of dust, and go whirling through the air, impelled by opposing currents.
Amid this tornado, an entire caravan, disorganized, broken, and overthrown, was disappearing beneath an avalanche of sand. The camels, flung pell-mell together, were uttering dull and pitiful groans; cries and howls of despair were heard issuing from that dusty and stifling cloud, and, from time to time, a parti-colored garment cut the chaos of the scene with its vivid hues, and the moaning and shrieking sounded over all, a terrible accompaniment to this spectacle of destruction.
Ere long the sand had accumulated in compact masses; and there, where so recently stretched a level plain as far as the eye could see, rose now a ridgy line of hillocks, still moving from beneath--the vast tomb of an entire caravan!
The doctor and Kennedy, pallid with emotion, sat transfixed by this fearful spectacle. They could no longer manage their balloon, which went whirling round and round in contending currents, and refused to obey the different dilations of the gas. Caught in these eddies of the atmosphere, it spun about with a rapidity that made their heads reel, while the car oscillated and swung to and fro violently at the same time. The instruments suspended under the awning clattered together as though they would be dashed to pieces; the pipes of the spiral bent to and fro, threatening to break at every instant; and the water-tanks jostled and jarred with tremendous din. Although but two feet apart, our aeronauts could not hear each other speak, but with firmly-clinched hands they clung convulsively to the cordage, and endeavored to steady themselves against the fury of the tempest.
Kennedy, with his hair blown wildly about his face, looked on without speaking; but the doctor had regained all his daring in the midst of this deadly peril, and not a sign of his emotion was betrayed in his countenance, even when, after a last violent twirl, the Victoria stopped suddenly in the midst of a most unlooked-for calm; the north wind had abruptly got the upper hand, and now drove her back with equal rapidity over the route she had traversed in the morning.
"Whither are we going now?" cried Kennedy.
"Let us leave that to Providence, my dear Dick; I was wrong in doubting it. It knows better than we, and here we are, returning to places that we had expected never to see again!"
The surface of the country, which had looked so flat and level when they were coming, now seemed tossed and uneven, like the ocean-billows after a storm; a long succession of hillocks, that had scarcely settled to their places yet, indented the desert; the wind blew furiously, and the balloon fairly flew through the atmosphere.
The direction taken by our aeronauts differed somewhat from that of the morning, and thus about nine o'clock, instead of finding themselves again near the borders of Lake Tchad, they saw the desert still stretching away before them.
Kennedy remarked the circumstance.
"It matters little," replied the doctor, "the important point is to return southward; we shall come across the towns of Bornou, Wouddie, or Kouka, and I should not hesitate to halt there."
"If you are satisfied, I am content," replied the Scot, "but Heaven grant that we may not be reduced to cross the desert, as those unfortunate Arabs had to do! What we saw was frightful!"
"It often happens, Dick; these trips across the desert are far more perilous than those across the ocean. The desert has all the dangers of the sea, including the risk of being swallowed up, and added thereto are unendurable fatigues and privations."
"I think the wind shows some symptoms of moderating; the sand-dust is less dense; the undulations of the surface are diminishing, and the sky is growing clearer."
"So much the better! We must now reconnoitre attentively with our glasses, and take care not to omit a single point."
"I will look out for that, doctor, and not a tree shall be seen without my informing you of it."
And, suiting the action to the word, Kennedy took his station, spy-glass in hand, at the forward part of the car.
CHAPTER THIRTY
-FIFTH.
What happened to Joe.--The Island of the Biddiomahs.--The Adoration shown him.--The Island that sank.--The Shores of the Lake.--The Tree of the Serpents.--The Foot-Tramp.--Terrible Suffering.--Mosquitoes and Ants.--Hunger.--The Victoria seen.--She disappears.--The Swamp. --One Last Despairing Cry.
What had become of Joe, while his master was thus vainly seeking for him?
When he had dashed headlong into the lake, his first movement on coming to the surface was to raise his eyes and look upward. He saw the Victoria already risen far above the water, still rapidly ascending and growing smaller and smaller. It was soon caught in a rapid current and disappeared to the northward. His master--both his friends were saved!
"How lucky it was," thought he, "that I had that idea to throw myself out into the lake! Mr. Kennedy would soon have jumped at it, and he would not have hesitated to do as I did, for nothing's more natural than for one man to give himself up to save two others. That's mathematics!"
Satisfied on this point, Joe began to think of himself. He was in the middle of a vast lake, surrounded by tribes unknown to him, and probably ferocious. All the greater reason why he should get out of the scrape by depending only on himself. And so he gave himself no farther concern about it.
Before the attack by the birds of prey, which, according to him, had behaved like real condors, he had noticed an island on the horizon, and determining to reach it, if possible, he put forth all his knowledge and skill in the art of swimming, after having relieved himself of the most troublesome part of his clothing. The idea of a stretch of five or six miles by no means disconcerted him; and therefore, so long as he was in the open lake, he thought only of striking out straight ahead and manfully.
In about an hour and a half the distance between him and the island had greatly diminished.
But as he approached the land, a thought, at first fleeting and then tenacious, arose in his mind. He knew that the shores of the lake were frequented by huge alligators, and was well aware of the voracity of those monsters.
Now, no matter how much he was inclined to find every thing in this world quite natural, the worthy fellow was no little disturbed by this reflection. He feared greatly lest white flesh like his might be particularly acceptable to the dreaded brutes, and advanced only with extreme precaution, his eyes on the alert on both sides and all around him. At length, he was not more than one hundred yards from a bank, covered with green trees, when a puff of air strongly impregnated with a musky odor reached him.
"There!" said he to himself, "just what I expected. The crocodile isn't far off!"
With this he dived swiftly, but not sufficiently so to avoid coming into contact with an enormous body, the scaly surface of which scratched him as he passed. He thought himself lost and swam with desperate energy. Then he rose again to the top of the water, took breath and dived once more. Thus passed a few minutes of unspeakable anguish, which all his philosophy could not overcome, for he thought, all the while, that he heard behind him the sound of those huge jaws ready to snap him up forever. In this state of mind he was striking out under the water as noiselessly as possible when he felt himself seized by the arm and then by the waist.
Poor Joe! he gave one last thought to his master; and began to struggle with all the energy of despair, feeling himself the while drawn along, but not toward the bottom of the lake, as is the habit of the crocodile when about to devour its prey, but toward the surface.
So soon as he could get breath and look around him, he saw that he was between two natives as black as ebony, who held him, with a firm gripe, and uttered strange cries.
"Ha!" said Joe, "blacks instead of crocodiles! Well, I prefer it as it is; but how in the mischief dare these fellows go in bathing in such places?"
Joe was not aware that the inhabitants of the islands of Lake Tchad, like many other negro tribes, plunge with impunity into sheets of water infested with crocodiles and caymans, and without troubling their heads about them. The amphibious denizens of this lake enjoy the well-deserved reputation of being quite inoffensive.
But had not Joe escaped one peril only to fall into another? That was a question which he left events to decide; and, since he could not do otherwise, he allowed himself to be conducted to the shore without manifesting any alarm.
"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!
