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.

"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.
