"Too late? What do you mean!" asked Nort.

"I mean to save Rosemary—and Floyd. Those Yaquis—they're regular devils when they get on the war path! Oh, I hope we aren't too late!"

It was a hope the others shared.

Rapid action replaced the comparative quiet that reigned during the reading of the telegram. Cowboys rode to and fro, and Bud and his cousins prepared to depart for Diamond X Second to arrange for taking the trail against the Yaquis.

As the boy ranchers rode off down the trail, promising to return as speedily as possible, to join with the bunch from Diamond X, their eager talk over the recent events was interrupted by the noise of shouting.

"What's that?" cried Dick, looking in the direction of the noise. It appeared to come from a swale, or depression among some small, rounded knolls.

"Sounds like a cattle stampede," remarked Bud, urging his pony forward.
"And yet it can't be that."

Nort and Dick followed as soon as they could swing their horses about. The sound of shouting and the thunder of the feet of many animals—horses or steers—came more plainly to the ears of the boy ranchers.
