"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, d.i.c.k? Look!"
They had just pa.s.sed 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!" a.s.sented 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, d.i.c.k," 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. d.i.c.k! 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.
The doctor consulted his barometer, and at once discovered the cause of these symptoms.
"Are we descending?" asked Kennedy.
"Yes!" replied the doctor.
"The mischief!" thought Joe In the lapse of fifteen minutes the Victoria was only one hundred and fifty feet above the ground; but the wind was much stronger than before.
The Talabas checked their horses, and soon a volley of musketry pealed out on the air.
"Too far, you fools!" bawled Joe. "I think it would be well to keep those scamps at a distance."
And, as he spoke, he aimed at one of the hors.e.m.e.n who was farthest to the front, and fired. The Talaba fell headlong, and, his companions halting for a moment, the balloon gained upon them.
"They are prudent!" said Kennedy.
"Because they think that they are certain to take us," replied the doctor; "and, they will succeed if we descend much farther. We must, absolutely, get higher into the air."
"What can we throw out?" asked Joe.
"All that remains of our stock of pemmican; that will be thirty pounds less weight to carry."
"Out it goes, sir!" said Joe, obeying orders.
The car, which was now almost touching the ground, rose again, amid the cries of the Talabas; but, half an hour later, the balloon was again falling rapidly, because the gas was escaping through the pores of the covering.
Ere long the car was once more grazing the soil, and Al-Hadji"s black riders rushed toward it; but, as frequently happens in like cases, the balloon had scarcely touched the surface ere it rebounded, and only came down again a mile away.
"So we shall not escape!" said Kennedy, between his teeth.
"Throw out our reserved store of brandy, Joe," cried the doctor; "our instruments, and every thing that has any weight, even to our last anchor, because go they must!"
Joe flung out the barometers and thermometers, but all that amounted to little; and the balloon, which had risen for an instant, fell again toward the ground.
The Talabas flew toward it, and at length were not more than two hundred paces away.
"Throw out the two fowling-pieces!" shouted Ferguson.
"Not without discharging them, at least," responded the sportsman; and four shots in quick succession struck the thick of the advancing group of hors.e.m.e.n. Four Talabas fell, amid the frantic howls and imprecations of their comrades.
The Victoria ascended once more, and made some enormous leaps, like a huge gum-elastic ball, bounding and rebounding through the air. A strange sight it was to see these unfortunate men endeavoring to escape by those huge aerial strides, and seeming, like the giant Antaeus, to receive fresh strength every time they touched the earth. But this situation had to terminate. It was now nearly noon; the Victoria was getting empty and exhausted, and a.s.suming a more and more elongated form every instant. Its outer covering was becoming flaccid, and floated loosely in the air, and the folds of the silk rustled and grated on each other.
"Heaven abandons us!" said Kennedy; "we have to fall!"
Joe made no answer. He kept looking intently at his master.
"No!" said the latter; "we have more than one hundred and fifty pounds yet to throw out."
"What can it be, then?" said Kennedy, thinking that the doctor must be going mad.
"The car!" was his reply; "we can cling to the network. There we can hang on in the meshes until we reach the river. Quick! quick!"
And these daring men did not hesitate a moment to avail themselves of this last desperate means of escape. They clutched the network, as the doctor directed, and Joe, holding on by one hand, with the other cut the cords that suspended the car; and the latter dropped to the ground just as the balloon was sinking for the last time.
"Hurrah! hurrah!" shouted the brave fellow exultingly, as the Victoria, once more relieved, shot up again to a height of three hundred feet.
The Talabas spurred their horses, which now came tearing on at a furious gallop; but the balloon, falling in with a much more favorable wind, shot ahead of them, and was rapidly carried toward a hill that stretched across the horizon to the westward. This was a circ.u.mstance favorable to the aeronauts, because they could rise over the hill, while Al-Hadji"s horde had to diverge to the northward in order to pa.s.s this obstacle.
The three friends still clung to the network. They had been able to fasten it under their feet, where it had formed a sort of swinging pocket.
Suddenly, after they had crossed the hill, the doctor exclaimed: "The river! the river! the Senegal, my friends!"
And about two miles ahead of them, there was indeed the river rolling along its broad ma.s.s of water, while the farther bank, which was low and fertile, offered a sure refuge, and a place favorable for a descent.
"Another quarter of an hour," said Ferguson, "and we are saved!"
But it was not to happen thus; the empty balloon descended slowly upon a tract almost entirely bare of vegetation. It was made up of long slopes and stony plains, a few bushes and some coa.r.s.e gra.s.s, scorched by the sun.
The Victoria touched the ground several times, and rose again, but her rebound was diminishing in height and length. At the last one, it caught by the upper part of the network in the lofty branches of a baobab, the only tree that stood there, solitary and alone, in the midst of the waste.
"It"s all over," said Kennedy.
"And at a hundred paces only from the river!" groaned Joe.
The three hapless aeronauts descended to the ground, and the doctor drew his companions toward the Senegal.
At this point the river sent forth a prolonged roaring; and when Ferguson reached its bank, he recognized the falls of Gouina. But not a boat, not a living creature was to be seen. With a breadth of two thousand feet, the Senegal precipitates itself for a height of one hundred and fifty, with a thundering reverberation. It ran, where they saw it, from east to west, and the line of rocks that barred its course extended from north to south. In the midst of the falls, rocks of strange forms started up like huge ante-diluvian animals, petrified there amid the waters.
The impossibility of crossing this gulf was self-evident, and Kennedy could not restrain a gesture of despair.
But Dr. Ferguson, with an energetic accent of undaunted daring, exclaimed- "All is not over!"
"I knew it," said Joe, with that confidence in his master which nothing could ever shake.
The sight of the dried-up gra.s.s had inspired the doctor with a bold idea. It was the last chance of escape. He led his friends quickly back to where they had left the covering of the balloon.
"We have at least an hour"s start of those banditti," said he; "let us lose no time, my friends; gather a quant.i.ty of this dried gra.s.s; I want a hundred pounds of it, at least."
"For what purpose?" asked Kennedy, surprised.
"I have no more gas; well, I"ll cross the river with hot air!"
"Ah, doctor," exclaimed Kennedy, "you are, indeed, a great man!"
Joe and Kennedy at once went to work, and soon had an immense pile of dried gra.s.s heaped up near the baobab.
In the mean time, the doctor had enlarged the orifice of the balloon by cutting it open at the lower end. He then was very careful to expel the last remnant of hydrogen through the valve, after which he heaped up a quant.i.ty of gra.s.s under the balloon, and set fire to it.
It takes but a little while to inflate a balloon with hot air. A head of one hundred and eighty degrees is sufficient to diminish the weight of the air it contains to the extent of one-half, by rarefying it. Thus, the Victoria quickly began to a.s.sume a more rounded form. There was no lack of gra.s.s; the fire was kept in full blast by the doctor"s a.s.siduous efforts, and the balloon grew fuller every instant.
It was then a quarter to four o"clock.
At this moment the band of Talabas reappeared about two miles to the northward, and the three friends could hear their cries, and the clatter of their horses galloping at full speed.
"In twenty minutes they will be here!" said Kennedy.
"More gra.s.s! more gra.s.s, Joe! In ten minutes we shall have her full of hot air."
"Here it is, doctor!"
The Victoria was now two-thirds inflated.
"Come, my friends, let us take hold of the network, as we did before."
"All right!" they answered together.
In about ten minutes a few jerking motions by the balloon indicated that it was disposed to start again. The Talabas were approaching. They were hardly five hundred paces away.
"Hold on fast!" cried Ferguson.
"Have no fear, master-have no fear!"
And the doctor, with his foot pushed another heap of gra.s.s upon the fire.
With this the balloon, now completely inflated by the increased temperature, moved away, sweeping the branches of the baobab in her flight.
"We"re off!" shouted Joe.
A volley of musketry responded to his exclamation. A bullet even ploughed his shoulder; but Kennedy, leaning over, and discharging his rifle with one hand, brought another of the enemy to the ground.
Cries of fury exceeding all description hailed the departure of the balloon, which had at once ascended nearly eight hundred feet. A swift current caught and swept it along with the most alarming oscillations, while the intrepid doctor and his friends saw the gulf of the cataracts yawning below them.
Ten minutes later, and without having exchanged a word, they descended gradually toward the other bank of the river.
There, astonished, speechless, terrified, stood a group of men clad in the French uniform. Judge of their amazement when they saw the balloon rise from the right bank of the river. They had well-nigh taken it for some celestial phenomenon, but their officers, a lieutenant of marines and a naval ensign, having seen mention made of Dr. Ferguson"s daring expedition, in the European papers, quickly explained the real state of the case.
The balloon, losing its inflation little by little, settled with the daring travellers still clinging to its network; but it was doubtful whether it would reach the land. At once some of the brave Frenchmen rushed into the water and caught the three aeronauts in their arms just as the Victoria fell at the distance of a few fathoms from the left bank of the Senegal.
"Dr. Ferguson!" exclaimed the lieutenant.
"The same, sir," replied the doctor, quietly, "and his two friends."
The Frenchmen escorted our travellers from the river, while the balloon, half-empty, and borne away by a swift current, sped on, to plunge, like a huge bubble, headlong with the waters of the Senegal, into the cataracts of Gouina.
"The poor Victoria!" was Joe"s farewell remark.
The doctor could not restrain a tear, and extending his hands his two friends wrung them silently with that deep emotion which requires no spoken words.
