At one place we passed a rock in the water so large that it almost blocked the entire stream, which had averaged about two hundred feet in width, though narrowing at many places to no more than seventy-five.

The current was always extremely swift, while many whirlpools added their demands, though they gave us no serious trouble.

It is exasperating, however, to be turned around against one's will.

The canyon at the top for a considerable distance was not over three-quarters of a mile wide.
The depth was now from fifteen hundred to eighteen hundred feet.

There were always rapids following quickly one after another, but so often they were free from rocks, the dangerous part of most rapids, that we were able to sail through them in triumph.
