The boy's smile left his face and clucking to his pony he rode slowly forward toward the angry cowpuncher, meeting the fellow's menacing eyes unflinchingly.

"Is there anything you wish to say to me, Mr. Bates?" asked the lad calmly.

Lumpy's emotions were almost too great for speech. He controlled himself with an effort.

"No—only this. I—I'll forget myself some day, and clean up one of you idiotic tenderfeet."

"Perhaps you would like to begin on me, sir," said Tad steadily. "If you feel that way I should prefer to have you do that rather than to try it on any of my companions. Stacy Brown may be indiscreet, but I'd have you understand he is no idiot."

"What—what——"

"You have determined to get square with us ever since we joined out with you last night, and I knew that you and I would have to have an understanding before long. We might as well have it now, though there's nothing of enough consequence to have a quarrel about——"

"You threaten me?"

"Nothing of the kind, Mr. Bates. I only wish to tell you that my companions are the guests of this outfit, and we propose to act like gentlemen. Every other member of the outfit, not excepting the Chinaman, has given us fine treatment. You have hung back, hoping you would have a chance to get us run off the trail."

The cowpuncher's fingers were opening and closing convulsively.
