As each man arrived he dismounted, threw off his saddle, and turned his animal loose.

Then he flipped a loop in his rope and disappeared in the eddying herd.

The discarded horse, with many grunts, indulged in a satisfying roll, shook himself vigorously, and walked slowly away.

His labour was over for the day, and he knew it, and took not the slightest trouble to get out of the way of the men with the swinging ropes.
Not so the fresh horses, however.

They had no intention of being caught, if they could help it, but dodged and twisted, hid and doubled behind the moving screen of their friends.
