"Don't talk so much, Chunky," begged Tad, after they had gone on some distance. "You should keep your eyes out for signs."

"What kind of signs?"

"Water signs. Come, be serious for a little while. You can have all the sport you want when we get back. I think, Chunky, that we can both work to better advantage if we separate——"

"What, you want to get rid of me so soon?"

"No, no! Listen! You ride off there to the right, say half a mile. Keep within sight of me all the time, and watch carefully for what we are in search of. We shall be able to do twice as effective work in that way."

"I see. I guess that would be a good idea. Got anything to eat in your pocket?"

"Some dry bread. I'll divide with you. You should have brought something."

The fat boy, well satisfied now, rode away to the north, munching the dry food that Tad had given him. So long as Chunky had plenty to eat, nothing else mattered.

Tad soon espied what appeared to him to be a cloud on the horizon ahead. After a time he discovered that it was a range of irregular buttes. On some of them he eventually made out what looked like scattering trees. Tad increased the speed of his pony as much as he thought the animal would stand. If there were trees, there surely should be water as well, he reasoned. After a time he succeeded in attracting the attention of Stacy, whom he motioned to him.

The fat boy put spurs to his mount, racing along one side of the triangle, heading for the range, for which he observed that Tad was riding. It was now a test of speed to see which one should get there first. Tad having the shorter distance to travel, made the mark ahead of his companion, though with little to spare.
