“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 aëronauts, 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.
