"Who are you and what are you doing?"

"We're from Diamond X ranch," replied Snake, "and we're on the trail of the Yaquis who have captured some of our friends!"

"Oh, the Yaquis!" exclaimed the trooper, in evident surprise. "Why, we're after the same bloody beggars! Glad to have met you. We seem to be off the trail for some reason. Captain Marshal will want to speak to you. Better come with me."

"Wait 'til I get my horse," murmured Snake, for, like all westerners, he hated to take more than a few steps out of the saddle.

A moment later he was riding toward the officers of Uncle Sam's troopers, while the remainder of the lancers riding in, mingled with the small force from Diamond X.

"It's good to see you fellows!" chuckled Bud as the bronze-faced soldiers gathered around the boy ranchers.

"We were just about to open fire on you," said one of the lancers, and Nort and Dick noticed that in addition to the steel-tipped weapon each trooper carried a carbine and wore a revolver in his belt. The lances were, in reality, more for show than for actual use, though in charging the hostile Indians the spears had served many a useful purpose.

"Glad you didn't," said Yellin' Kid. "There'd have been trouble, for we were all primed for you," and he waved his hand toward the rocks amid which some cowboys were just arising, picking up the ammunition they had spread out for quick use.

"We thought you were Yaquis, and we had orders to shoot to kill," explained another trooper.

"And we took you for Indians—not exactly Yaquis, for they don't carry lances," said Dick. "I'm glad it was a mistake all around."
