Notwithstanding that Benito did not leave a single point of the river unexplored, he never caught sight of the object of his search. He noticed, however, that the slope of the river bed was very abrupt, and he concluded that Torres had rolled beyond the eddy toward the center of the stream. If so, he would probably still recover the body, for the current could hardly touch it at the depth, which was already great, and seemed sensibly to increase. Benito then resolved to pursue his investigations on the side where he had begun to probe the vegetation. This was why he continued to advance in that direction, and the raft had to follow him during a quarter of an hour, as had been previously arranged.

The quarter of an hour had elapsed, and Benito had found nothing. He felt the need of ascending to the surface, so as to once more experience those physiological conditions in which he could recoup his strength. In certain spots, where the depth of the river necessitated it, he had had to descend about thirty feet. He had thus to support a pressure almost equal to an atmosphere, with the result of the physical fatigue and mental agitation which attack those who are not used to this kind of work. Benito then pulled the communication cord, and the men on the raft commenced to haul him in, but they worked slowly, taking a minute to draw him up two or three feet so as not to produce in his internal organs the dreadful effects of decompression.
