Reaching his friend, who had stopped and also was scanning the desert floor with great intentness, he nodded in quiet satisfaction.

"They're so faint they can't hardly be seen, not till you look ahead, an' then it's only th' difference between this strip of sand that we're on an' th' rest of th' desert. It's a cattle trail, Hoppy; I just found another water-hole, a big one. Th' bank was crowded with hoof marks, cattle an' cayuses. Looks like they come from th' west, bearin' a little north. Th' only reason we didn't see 'em when we rode down was because they was on hard ground. That shore explains th' dead cow."
