Not a day passed that somewhere along Henri's trap-line they did not see the trails of the two wolves, and Weyman observed that--as Henri had told him--the footprints were always two by two, and never one by one.

On the third day they came to a trap that had held a lynx, and at sight of what remained Henri cursed in both French and English until he was purple in the face.

The lynx had been torn until its pelt was practically worthless.
Weyman saw where the smaller wolf had waited on its haunches, while its companion had killed the lynx.

He did not tell Henri all he thought.

But the days that followed convinced him more and more that he had found the most dramatic exemplification of his theory.
