This was a great relief, and Buck caused even the weazened face of Perrault to twist itself into a grin one morning, when Francois forgot the moccasins and Buck lay on his back, his four feet waving appealingly in the air, and refused to budge without them.

Later his feet grew hard to the trail, and the worn-out foot-gear was thrown away.
At the Pelly one morning, as they were harnessing up, Dolly, who had never been conspicuous for anything, went suddenly mad.

She announced her condition by a long, heartbreaking wolf howl that sent every dog bristling with fear, then sprang straight for Buck.

He had never seen a dog go mad, nor did he have any reason to fear madness; yet he knew that here was horror, and fled away from it in a panic.

Straight away he raced, with Dolly, panting and frothing, one leap behind; nor could she gain on him, so great was his terror, nor could he leave her, so great was her madness.
