Billy, with an answering snort, responded to his master's words, and carefully picked his way over boulders and rocks down to the valley below.

But within a half mile of the water-hole the young man suddenly halted his horse and sprang from the saddle, stooping in the sand beside a tall yucca to pick up something that gleamed like fire in the sunlight. In all that brilliant glowing landscape a bit of brightness had caught his eye and insistently flung itself upon his notice as worthy of investigation. There was something about the sharp light it flung that spoke of another world than the desert. John Brownleigh could not pass it by. It might be only a bit of broken glass from an empty flask flung carelessly aside, but it did not look like that. He must see.

Wondering he stooped and picked it up, a bit of bright gold on the handle of a handsome riding whip. It was not such a whip as people in this region carried; it was dainty, costly, elegant, a lady's riding whip! It spoke of a world of wealth and attention to expensive details, as far removed from this scene as possible. Brownleigh stood still in wonder and turned the pretty trinket over in his hand. Now how did that whip come to be lying in a bunch of sage-brush on the desert? Jewelled, too, and that must have given the final keen point of light to the flame which made him stop short in the sand to pick it up. It was a single clear stone of transparent yellow, a topaz likely, he thought, but wonderfully alive with light, set in the end of the handle, and looking closely he saw a handsome monogram engraved on the side, and made out the letters H. R. But that told him nothing.

With knit brows he pondered, one foot in the stirrup, the other still upon the desert, looking at the elegant toy. Now who, who would be so foolish as to bring a thing like that into the desert? There were no lady riders anywhere about that he knew, save the major's sister at the military station, and she was most plain in all her appointments. This frivolous implement of horsemanship never belonged to the major's sister. Tourists seldom came this way. What did it mean?

He sprang into the saddle and shading his eyes with his hand scanned the plain, but only the warm shimmer of sun-heated earth appeared. Nothing living could be seen. What ought he to do about it? Was there any way he might find out the owner and restore the lost property?
