CHAPTER FORTIETH.

Dr. Ferguson's Anxieties.-Persistent Movement southward.-A Cloud of Gra.s.shoppers.-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-gla.s.s. "That's not a cloud!"

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

"No; it is a swarm."

"Eh?"

"A swarm of gra.s.shoppers!"

"That? Gra.s.shoppers!"

"Myriads of gra.s.shoppers, 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 gra.s.shopper called crickets. About a hundred paces from the balloon, they settled down upon a tract full of foliage and verdure. Fifteen minutes later, the ma.s.s 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 gra.s.shopper 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 ma.s.s, and the rest of the swarm would then pa.s.s 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 acc.u.mulated 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 pa.s.s. 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 a.s.sumed 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, d.i.c.k, 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, reconnaissances have been pushed far up into the country. Officers such as Messrs. Pascal, Vincent, and Lambert, have brought back precious doc.u.ments 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, ma.s.sacring 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 repa.s.sed 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 a.s.sure 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 pa.s.s, 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-gla.s.s, "and they look very high. We shall have some trouble in crossing them."

"Can we not avoid them?"

"I am afraid not, d.i.c.k. See what an immense s.p.a.ce 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 pa.s.s 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 pa.s.s 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 pa.s.sing them!"

"Well, doctor?" queried Joe.
