Then he was flung back--twenty feet.

Hunger gnawing at his vitals robbed him of all caution, and he sprang to the attack again--full at the bull's front--while Gray Wolf crept up unseen behind, seeking in her blindness the vulnerable part which nature had not taught Kazan to find.
This time Kazan was caught fairly on the broad palmate leaf of the bull's antler, and he was flung back again, half stunned.

In that same moment Gray Wolf's long white teeth cut like knives through one of the bull's rope-like hamstrings.

For thirty seconds she kept the hold, while the bull plunged wildly in his efforts to trample her underfoot.

Kazan was quick to learn, still quicker to be guided by Gray Wolf, and he leaped in again, snapping for a hold on the bulging cord just above the knee.
