ADVENTURES OF CAPTAIN HORN
In their search for water, game, or fellow-beings, no one had climbed these desolate rocks, apparently dry and barren. But still the captain was puzzled as to the way the water had gone out of the lake. He did not believe that it had flowed through the ravine below. There were no signs that there had been a flood down there. Little vines and plants were growing in chinks of the rocks close to the water. And, moreover, had a vast deluge rushed out almost beneath the opening which lighted the cave, it must have been heard by some of the party. He concluded, therefore, that the water had escaped through a subterranean channel below the rocks from which he looked down.
He climbed down the sides of the gorge, and walked along its bottom for two or three hundred yards, until around a jutting point of rock he saw that the sides of the defile separated for a considerable distance, and then, coming together again below, formed a sort of amphitheatre. The bottom of this was a considerable distance below him, and he did not descend into it, but he saw plainly that it had recently contained water, for pools and puddles were to be seen everywhere.
At the other end of it, where the rocks again approached each other, was probably a precipice. After a few minutes cogitation, Captain Horn felt sure that he understood the whole matter: a subway from the lake led to this amphitheatre, and thus there had been no audible rush of the waters until they reached this point, where they poured in and filled this great basin, the lower end of which was probably stopped up by accumulations of sand and deposits, which even in that country of scant vegetation had accumulated in the
