“Shut up!” Thurston commanded inelegantly. “I'd like to see you ride a horse when he's upside down!”

“Aw, come on,” urged Bob, giving up the argument. “We'll be plumb lost from the herd if we don't hustle.”

They got into their saddles again and went on, riding by sound and the rare glimpses the lightning gave them as it flared through the storm away to the east.

“Wet?” Bob sung out sympathetically from the streaming shelter of his slicker. Thurston, wriggling away from his soaked clothing, grunted a sarcastic negative.

The cattle were drifting now before the storm which had settled to a monotonous downpour. The riders—two or three men for every herd that had joined in the panic—circled, a veritable picket line without the password. There would be no relief ride out to them that night, and they knew it and settled to the long wait for morning.

Thurston took up his station next to Bob; rode until he met the next man, and then retraced his steps till he faced Bob again; rode until the world seemed unreal and far away, with nothing left but the night and the riding back and forth on his beat, and the rain that oozed through his clothes and trickled uncomfortably down inside his collar. He lost all count of time, and was startled when at last came gray dawn.

As the light grew brighter his eyes widened and forgot their sleep-hunger; he had not thought it would be like this. He was riding part way across one end of a herd larger than his imagination had ever pictured; three thousand cattle had seemed to him a multitude—yet here were more than twenty thousand, wet, draggled, their backs humped miserably from the rain which but a half hour since had ceased. He was still gazing and wondering when Park rode up to him.

“Lord! Bud, you're a sight! Did the bunch walk over yuh?” he greeted.

“No, only Sunfish,” snapped Thurston crossly. Time was when Philip Thurston would not have answered any man abruptly, however great the provocation. He was only lately getting down to the real, elemental man of him; to the son of Bill Thurston, bull-whacker, prospector, follower of dim trails. He rode silently back to camp with Bob, ate his breakfast, got into dry clothes and went out and tied his slicker deliberately and securely behind the cantle of his saddle, though the sun was shining straight into his eyes and the sky fairly twinkled, it was so clean of clouds.

Bob watched him with eyes that laughed. “My, you're an ambitious son-of-a-gun,” he chuckled. “And you've got the slicker question settled in your mind, I see; yuh learn easy; it takes two or three soakings to learn some folks.”
