For the first time he was looking upon _battle_, and the thrill of it sent the blood hot and fast through his little body.

With a faint, puppyish snarl he darted in.

His teeth sank futilely into the thick hair and tough hide of the black's rump.

He pulled and he snarled; he braced himself with his forefeet and tugged at his mouthful of hair, filled with a blind and unaccountable rage.
The black twisted himself upon his back, and one of his hind feet raked Thor from chest to vent.

That stroke would have disembowelled a caribou or a deer; it left a red, open, bleeding wound three feet long on Thor.
Before it could be repeated, the grizzly swung himself sidewise, and the second blow caught Muskwa.
