After dinner, the boats were lowered over the rapid, fall, cataract, or whatever it might be called, before which we had paused, and then in short order over four more tremendous ones.

When we had run a fifth, in which we received a violent shaking-up, we went into camp on the left bank at the head of another roarer, or pair of them, and hastened to throw off our saturated clothes and put on the dry from out the friendly rubber sacks.

I never before understood the comfort of being dry.

The topographers recorded a good day's work: nine miles and eight powerful cataracts.

Cataract, we decided was the proper name for these plunges, for though they were by no means vertical, they were more violent than what is ordinarily called a rapid.
