From the left side of the herd came another rider—Soapy. He tore ahead of the vanguard of running steers, shooting his pistol in their faces, shouting profanely at them, lashing them with his quirt.

A first batch slipped by him. He spurred his horse close to Sanderson—who was trying to head off still others of the herd that were determined to follow the first—and cursed loudly:

"Who in hell waved that tarp?"

Sanderson had no time to answer. A score of steers bolted straight for him, and he groaned again when he saw that the whole herd was rushing forward in a mass. A common impulse moved them; they were frenzied with fright and terror.

It was not the first stampede that Sanderson had been in, and he knew its dangers. Yet he grimly fought with the cattle, Streak leaping here and there in answer to the knee-pressure of his master, horse and rider looking like knight and steed of some fabled romance, embattled with a huge monster with thousands of legs.

Sanderson caught a glimpse of several riders tearing toward him from the direction of the camp, and he knew that Carter and the others were trying to reach him in the hope of being able to stem the torrent of rushing cattle.

But the movement had already gone too far, and the speed of the frenzied steers was equal to the best running that Streak could do.

Sanderson saw that all effort to stop them would be hopeless, and aware of the danger of remaining at the head of the flying mass, he veered Streak off, heading him toward the side, out of the press.

As he rode he caught a glimpse of Soapy. The latter had the same notion that was in Sanderson's mind, for he was leaning over his pony's mane, riding hard to get out of the path taken by the herd.

Sanderson pulled Streak up slightly, watching Soapy until he was certain the latter would reach the edge, then he gave Streak the reins again.
