"Then nobody knows where he is?"

"That's it."

Blank looks were exchanged as they clustered about the rancher to hear what the chief of the Moquis had visited him for. Evidently, from the rancher's manner, there were graver thoughts still in his mind.

"To explain to you what is to follow," he said, "I must say that things are now at a crisis as regards the leadership of the Moquis tribe. For the first time in many years Black Cloud's power is threatened. A younger chief, named Diamond Snake, has attained great supremacy in the tribe, and is using his influence to undermine the leadership of Black Cloud. Diamond Snake is not a full-blooded Indian, but he once worked for Clark Jennings on his father's ranch, before the family moved here."

"Gosh-jigger them!" burst out Blinky devoutly.

"Black Cloud, who is a pretty sensible Indian, refused to have anything to do with Jennings and his gang, and as late as last night, he tells me, warned them not to try to implicate his tribe in trouble. In spite of that, an attack is to be made on our mavericks in the Far Pasture by Jennings and his crowd, disguised as Moquis, and——"

"It was Jennings and that bunch, for a bet, that stampeded the cattle!" cried Blinky.

"I think so. They could easily rig themselves up as Moquis and deceive any one, particularly in the excitement. Black Cloud became suspicious after his interview with Jennings, and laid in hiding in the brush. What he heard confirmed his suspicion that Jennings meant to disguise himself and his helpers as Indians, when they raided the cattle, and so throw the blame on the tribe. Old Black Cloud readily saw that this would work him immeasurable harm, so rode right off to warn me."

"But why should he do this?" asked Merritt.

"It's clear enough," rejoined the rancher. "He knows I'm pretty influential, and he also knows that there's a hot time coming for his tribe when they are finally rounded up. By coming to me and telling me of Jennings's plans, he figures that I, on my part, will go to the front for him and save his tribe from any severe penalty."
