"They're on the dogs!" Jones pushed his cocked rifle ahead of him and straightened up outside the tepee.

A wolf, large as a panther and white as the gleaming snow, sprang at him.

Even as he discharged his rifle, right against the breast of the beast, he saw its dripping jaws, its wicked green eyes, like spurts of fire and felt its hot breath.
