The Indians fell away from him like waves from a speeding vessel.

On the other side of the little bluff he caught sight of a mounted Indian flying toward the mountains and with a cry he started in pursuit.

It took only a few minutes for Cameron to discover that he was gaining rapidly upon his man.

But the rough rocky country was not far away in front of them, and here was abundant chance for hiding.

Closer and closer he drew to his flying enemy--a hundred yards--seventy-five yards--fifty yards only separated them.
"Halt!" cried Cameron, "or I shoot." But the Indian, throwing himself on the far side of his pony, urged him to his topmost speed.
Cameron steadied himself for a moment, took careful aim and fired.
