Wild Life on the Rockies by Enos A. Mills

In many of the Western mining-towns, the liverymen keep "return horses," -- horses that will return to the barn when set at liberty, whether near the barn or twenty miles away. These horses are the pick of their kind. They have brains enough to take training readily, and also to make plans of their own and get on despite the unexpected hindrances that sometimes occur. When a return horse is ridden to a neighboring town, he must know enough to find his way back, and he must also be so well trained that he will not converse too long with the horse he meets going in the opposite direction.

The return horse is a result of the necessities of mountain sections, especially the needs of miners. Most Western mining-towns are located upon a flat or in a gulch. The mines are rarely near the town, but are on the mountain-slopes above it. Out of town go a dozen roads or trails that extend to the mines, from one to five miles away, and much higher than the town. A miner does not mind walking down to the town, but he wants to ride back; or the prospector comes in and wants to take back a few supplies. The miner hires a return horse, rides it to the mine, and then turns the horse loose. It at once starts to return to the barn. If a horse meets a freight wagon coming up, it must hunt for a turnout if the road is narrow, and give the wagon the right of way. If the horse meets some one walking up, it must avoid being caught.
