Fenno headed for the waterhole. His tired pony plodded along over the uneven ground with head adroop. Treve had moved from Pancho’s right side, to his left; seeking such tiny patch of shade as the mustang’s moving body might afford. The air hung dead and stifling. The sun blazed down in a copper glare from the pitilessly hot sky. Nature seemed dead and blistering.

Joel’s tough skin sweated drippingly. It was the hottest day, thus far, of the year; and the weatherwise man knew it was the first of at least three scorchingly hot days. He was not minded to continue the ride any farther than he must. It would be well to do what he had come to do, and then turn back toward the ranch.

This was as good a spot as any for his purpose. Here, at intervals, patches of soft and easily-diggable sand cropped out through the hardpan and rock. It would be easy enough to gouge a space deep enough to bury the body of a dog. Yes, and it would be best to do so, before getting any nearer to the waterhole. The presence of water might well attract other wayfarers,—men who might investigate a newly heaped mound of sand, in the dead level. The burial would better be here, a mile on the hither side of the waterhole and on a trackless bit of ground.

Joel Fenno halted his mustang, and glanced around to make certain he had the wide sweep of swooningly arid country to himself. In that pitilessly clear atmosphere, his keen old eyes could have descried any moving object, many miles away. Treve, still keeping in the shadow of the pony, stopped and looked inquiringly up at the man. It had been a long and fast and steady ride, under the sickeningly hot sun glare and over the ever-hotter hardpan. The dog was glad for a rest.

Then, suddenly, his attention was caught by Fenno’s upraised voice. Joel, in the course of his sweeping survey of the country behind him, had chanced to drop his gaze to the hips of his sweating and welt-skinned mount. He saw the water bag and the bundle of rations were gone from behind his saddle.

He was an old enough plainsman to realize what this implied. It meant he must go hungry until night—he who had ridden himself into such a hearty appetite. It meant, too, that he must do all his drinking from the muddy and perhaps alkaline puddle of the mile-distant waterhole; and that thereafter he must travel through the heat with unassuaged thirst until he should get back to the ranch at nightfall.

Small wonder that he burst into a roar of red profanity!

He knew well enough how the mischance had occurred. His spine still ached from the bucking of Pancho, four hours ago. It must have been during that series of jarring bucks that the water bag and the bundle had been loosened and had tumbled unheeded to earth. It was Pancho’s fault—all Pancho’s fault!

In a gust of wrath, he slashed the mustang across the neck with his quirt.
