On the prairies in the Far West of America a man lost his way. He had no water to drink, although both he and his horse were parched with thirst. Not knowing where to find water, he cast the reins on the neck of his horse. By means of that wonderful intelligence which some people wrongly call instinct, the horse found his way to a spring, although it was many miles distant. Thus both man and horse were able to quench their thirst, and in this way their lives were saved.
