"Let's don't be too sure of that, boys," cautioned Mr. Merkel. "What more did you hear, Billee Dobb? Is it at all serious? How many of the imps broke loose?"

"That I don't know, there's enough of 'em to make the government take action. Some of the regular troops have received orders to move, and they're on their way now. If there were only a scattered few of the Yaquis, Uncle Sam wouldn't be so anxious. They've raided one Arizona town, I heard."

"They have!" cried Nort, Dick and Bud in a breath.

"Why this must have happened several days ago," exclaimed Mr. Merkel. "The Yaquis are quartered some distance from here, and news doesn't travel as fast as all that. How do you account for it, Billee?"

"Well, the fellow who told me got his information from one of those scavengers," explained Billee.

"Scavengers!" cried Bud.

"Yes, you know—one of them fellers that go up in flyin' machines," explained the old cow puncher.

"Oh, you mean aviators!" exploded Bud, trying not to laugh.

"Well, something like that, yes," admitted Billee. "Word of the rising of the Indians was sent out by wireless, and some of the flying machines were ordered to the border. One of 'em who was flying around here had tire trouble, or something like that, and had to come down. It was from him the boys back in town got some of the news, and the deputy sheriff gave out the rest.

"Oh, the Yaquis are risin' up all right, and they may come out here. I rode over like a prairie fire to let you folks know. We've had trouble enough here at Diamond X and I didn't want any more."
