"What!" roared the old trapper. "Do you mean to tell me thet measly crowd is around here ag'in?"

"Three of 'em are—Gilroy, Fetter, and a young fellow named Potts. I think Potts comes from Denver."

"I know him. His father was Ike Potts, the card-sharp. Thet blood is about as bad as any in the gang. What are they up to?"

"They are laying a trap for the quartermaster when he comes through with the soldiers' money. Joe heard part of their talk by accident. Do you know when the quartermaster is expected?"

"I do not. Ye see, ever since old Cap'n Bissile was held up the army officers keep mum about the movements of the cash-box. I reckon they have orders from Washington to do it."

"I want to warn Colonel Fairfield as soon as I can," went on the old scout.

"Yes, he ought to be warned."

"Can you lend me a fresh hoss?"

"I can."

"Then I'll be off as soon as I've had a bit of supper. The boys can stay with you all night, can't they?"
