The wild horse can run away from a man; but this protection fails at times. The horse-catchers--or "vaqueros," as they are called--are famous riders, and to see them capture a wild mustang is better than to go to a circus. The vaquero puts a Spanish saddle on a tame horse, and starts out to see what he can find. In front, on the high pommel of the saddle, he hangs in large coils a leather rope, about a hundred feet long, and called a lasso. It is made of strips of raw hide, braided by hand into a smooth, hard and very pretty rope. One end is secured to the saddle, and the other end has a slip-knot making a sliding noose. [Illustration: CAPTURING A WILD MUSTANG.] The vaquero has not long to wait, for there are droves of horses cantering or walking about over the swells and hollows of the prairie, with here and there a smaller group looking on, or watching a battle between two horses who wish to be captains of their bands or companies. Presently, there is a strange sound of tramping hoofs, like the sound of a squadron of cavalry, except that it has a grand, wild rush and swing such as no cavalry ever had, and a cloud of dark heads rises over a swell of the land. The leader sees the vaquero, and he halts suddenly, and the others pull up in a confused crowd, and toss their heads, and sniff the air, as if they scented danger near. The leader does not like the looks of things, and turns and slowly canters away, followed by all the rest, tramping in confusion through the yellow grass and wild barley. Presently they become frightened, and away they fly in a dusty throng.
