A'tim the Outcast was half Wolf, half Huskie Dog. That meant ferocity and bloodthirst on the one side, and knowledge of Man's ways on the other. Also, that he was an Outcast; for neither side of the house of his ancestry would have aught of him. A'tim was bred in the far Northland, where the Cree Indians trail the white snow-waste with Train Dogs; and one time A'tim had pressed an unwilling shoulder to a dog-collar. Now he was an outcast vagabond on the southern prairie, close to the Montana border-land.
