Without answering to this, Pawnee Brown turned to the youth.

"Tell me your yarn, Dick. I know there is some mistake here."

"There is not much to tell, Major. When the lariat broke up at the Devil's Chimney and I couldn't make you reply to my calls I ran off to get help and a rope. I intended to ride your mare back to camp, but when I got to where the mare had been tethered I found her gone and this bay loafing around in her place. I got on the bay, but, instead of riding to camp, the animal ran away with me and brought me here. These fellows were mighty rough on me, and that man was going to split my head open when you came along in the nick of time."

"That's a neat fairy tale," sneered Tucker. "This horse was stolen four hours ago. More than likely the boy couldn't manage him and lost his way and the horse tried to get back to where he belonged."

"That doesn't connect with what I know," answered Pawnee Brown, quietly. "My mare was tethered where he went to look for her. I might as well accuse you of riding down there, taking Bonnie Bird and leaving this nag in her place."

"Do you mean to insinuate we are horse thieves?" cried Ross hotly.

"I'm giving you as good as you send, that's all. Dick, have you any idea where Bonnie Bird is?"

"Not the slightest, sir."

The great scout heaved a sigh. The little racing mare was the very apple of his eye.

"I'll not give up the hunt until I have found her." He turned again to the cavalrymen. "If the finest little black mare, with a white blaze, that you ever saw strays into your camp remember she belongs to me," he went on. "I want her returned at once, and if anybody attempts to keep her there will be a hotter time than this Territory has seen for many a day. Dick, hop up behind me," and he turned to his horse.
