It was evident that the men did not know that he was there.
Whitey felt something warm stir against him, and, startled, put out his hand and encountered a hairy surface.

It was Sitting Bull, who had crawled into the bunk after Whitey had fallen asleep, and crowded in between the boy and the wall.

At the sound of String Beans' voice Whitey felt the hair along Bull's neck rise.

He remembered the dog's dislike for the two men, and put his hand over Bull's mouth to keep him from growling.

Whitey was glad he did not snore.
