The gully was fully fifty feet long and he dropped on his hands and knees and crawled to the upper end of it, away from the slope.

He saw one of Taggart's feet projecting from behind the rock and he brought his six-shooter to a poise.

The foot moved and disappeared.

Catching a glimpse of the rifle barrel coming into view around the edge of the rock, Calumet sank back into the gully.

Fifteen minutes later when he again cautiously raised his head above the level there was no sign of Taggart.
