Jules Verne: Five Weeks in a Balloon

18. CHAPTER EIGHTEENTH. (continued)

"Not yet. In fact, I shall go up a little, first, in order to get an exact idea of the configuration of the country."

The hydrogen expanded, and in less than ten minutes the balloon was soaring at a height of twenty-five hundred feet above the ground.

From that elevation could be distinguished an inextricable network of smaller streams which the river received into its bosom; others came from the west, from between numerous hills, in the midst of fertile plains.

"We are not ninety miles from Gondokoro," said the doctor, measuring off the distance on his map, "and less than five miles from the point reached by the explorers from the north. Let us descend with great care."

And, upon this, the balloon was lowered about two thousand feet.

"Now, my friends, let us be ready, come what may."

"Ready it is!" said Dick and Joe, with one voice.

"Good!"

In a few moments the balloon was advancing along the bed of the river, and scarcely one hundred feet above the ground. The Nile measured but fifty fathoms in width at this point, and the natives were in great excitement, rushing to and fro, tumultuously, in the villages that lined the banks of the stream. At the second degree it forms a perpendicular cascade of ten feet in height, and consequently impassable by boats.

"Here, then, is the cascade mentioned by Debono!" exclaimed the doctor.

The basin of the river spread out, dotted with numerous islands, which Dr. Ferguson devoured with his eyes. He seemed to be seeking for a point of reference which he had not yet found.

By this time, some blacks, having ventured in a boat just under the balloon, Kennedy saluted them with a shot from his rifle, that made them regain the bank at their utmost speed.
