From the tip-top we could see more than a hundred miles toward any point of the compass. West of us we saw several streams that were flowing away toward the Pacific; east of us the streams flowed to the Atlantic. I told Harriet that the many small streams we saw all grew larger as they neared the sea. Harriet lived at the "big" end of the Arkansas River. She suddenly wanted to know if I could show her the "little end of the Arkansas River." [Illustration: ON THE TIP-TOP OF LONG'S PEAK] After an hour on top we started downward and homeward, the little mountain-climber feeling happy and lively. But she was careful, and only once during the day did she slip, and this slip was hardly her fault: we were coming off an enormous smooth boulder that was wet from the new snow that was melting, when both Harriet's feet shot from under her and she fell, laughing, into my arms. "Hello, Top, I am glad to see you," said Harriet when we came to the horses. While riding homeward I told Harriet that I had often climbed the peak by moonlight. On the way down she said good-bye to the little trees at timber-line, the squirrels, and the ouzel. When I at last lifted Harriet off old Top at the cabin, many people came out to greet her. To all she said, "Yes, I'm tired, but some time I want to go up by moonlight." Midget, the Return Horse 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.
