Here Long-Hair stopped and, without a word, cut the thongs from Beverley's wrists.

This was astounding; the young man could scarcely realize it, nor was he ready to act.
"Swim water," Long-Hair said in a guttural murmur barely audible.
"Swim, damn!" Again it was necessary for Beverley's mind to act swiftly and with prudence.

The camp was yet within hailing distance.

A false move now would bring the whole pack howling to the rescue.

Something told him to do as Long-Hair ordered, so with scarcely a perceptible hesitation he scrambled down the bushy bank and slipped into the water, followed by Long-Hair, who seized him by one arm when he began to swim, and struck out with him into the boiling and tumbling current.
Beverley had always thought himself a master swimmer, but Long-Hair showed him his mistake.
