When he proposed the trip, he had forgotten about the dam before alluded to, and did not know that the water was pouring over it in such torrents that it was extremely dangerous.

As he went over the sloping volume of water, he was met at the bottom by an immense back wave which drove him under.

Where the clashing waves embraced each other, he was checked and held, being rolled like a log that is caught between a back and an undertow.
