Twice during the wait Buck disappeared into the black chaparral close at hand and struck a match under his coat to see the time, and on the last occasion he returned to Billy, remarking: "Got half an hour yet before I leave you. Are you sleepy?"

"No, not very; my head hurts too much to sleep," Billy replied, re-crossing his legs and settling himself in a more comfortable position. "When you leave I'll get up on my hoofs so I won't feel like dosing off. I won't wake Curtis unless I have to—he's about played out."

"You wake him when you think I've been gone half an hour," Buck ordered. "It'll take him some time to get his eyes open—we mustn't let any get away. They've got friends in Eagle, you know."

"Wish I could smoke," Billy remarked, wistfully.

"Why, you can," replied Buck, quickly. "Go back there in th' chaparral an' get away with a pipeful. I'll watch things till you come back, an' if I need you quick I can call. You've got near half an hour—make th' best of it."

"Here's th' gun—much obliged, Buck," and Billy disappeared, leaving the foreman to plan and watch. Buck glanced at the sleeping man occasionally when he heard him toss or mutter and wished he could let him sleep on undisturbed.

Suddenly a flash lighted up the top of the trail for an instant and the sharp report of a rifle rang out loudly on the still, night air. Buck, grabbing the Winchester, sprang to his feet as an excited chorus came from the rustlers' stronghold. Then he heard laughter and a few curses and quiet again ensued.

"What was that, Buck?" came a low, anxious hail from behind.

The foreman laughed softly and replied: "Nothing, Billy, except that th' guard up there reckoned he saw something to shoot at. It's funny how staring at th' dark will get a feller seeing things that ain't. Why, had yore smoke so soon?" he asked in surprise as Billy sat down beside him.

"Shore," replied Billy. "Two of 'em. I reckon yore time is about up. Gimme th' gun now."
