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 horsemen 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 everything 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 horsemen. 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 assuming 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 circumstance favorable to the aeronauts, because
