It was the rule among Pony Express Riders that upon arriving within a half mile of a station, they should proclaim the fact by giving the “coyote yell.” This was notice to their friends to have a fresh horse ready, for it must be borne in mind that the minutes were precious. As the panting animal dashed up, his rider sprang from the saddle before he had fairly halted and ready hands helped secure it to the back of the waiting horse. The messenger leaped like an acrobat into place, caught up the reins, touched with his spurs the flanks of the animal, which instantly responded with a bound, and was off on a headlong run.
