“I reckon not. There's been no rain.”

August spurred his roan after Dave, and Hare kept close behind them, till they reined in on a muddy bank. What had once been a waterhole was a red and yellow heap of shale, fragments of stones, gravel, and sand. There was no water, and the sheep were bleating. August dismounted and climbed high above the hole to examine the slope; soon he strode down with giant steps, his huge fists clinched, shaking his gray mane like a lion.

“I've found the tracks! Somebody climbed up and rolled the stones, started the cave-in. Who?”

“Holderness's men. They did the same for Martin Cole's waterhole at Rocky Point. How old are the tracks?”

“Two days, perhaps. We can't follow them. What can be done?”

“Some of Holderness's men are Mormons, and others are square fellows. They wouldn't stand for such work as this, and somebody ought to ride in there and tell them.”

“And get shot up by the men paid to do the dirty work. No. I won't hear of it. This amounts to nothing; we seldom use this hole, only twice a year when driving the flock. But it makes me fear for Silver Cup and Seeping Springs.”

“It makes me fear for the sheep, if this wind doesn't change.”

“Ah! I had forgotten the river scent. It's not strong to-night. We might venture if it wasn't for the strip of sand. We'll camp here and start the drive at dawn.”

The sun went down under a crimson veil; a dull glow spread, fan-shaped, upward; twilight faded to darkness with the going down of the wind. August Naab paced to and fro before his tired and thirsty flock.
