Injun's sharp eyes soon identified it as Sitting Bull.

The boys were first surprised, then sorry that Bull should have had such a long pursuit, but that did not keep back Whitey's laughter when Bull staggered up to where they waited for him.

He sure was a happy dog, and fatigue did not keep him from showing it, his method being to twist his body into almost a half-circle, wag his stump tail, and prance about gazing delightedly up at the boys.
As a hunting companion he was a frost.

"Him must go back," he said.
"How ?" asked Whitey.
More profound thought, and Injun spoke again.
