I once was engaged with a crew of cowboys in rounding up mustangs in southern Arizona. We would ride slowly in through the hills until we caught sight of the herds. Then it was a case of running them down and heading them off, of turning the herd, milling it, of rushing it while confused across country and into the big corrals. The surface of the ground was composed of angular volcanic rocks about the size of your two fists, between which the bunch-grass sprouted. An Eastern rider would ride his horse very gingerly and at a walk, and then thank his lucky stars if he escaped stumbles. The cowboys turned their mounts through at a dead run. It was beautiful to see the ponies go, lifting their feet well up and over, planting them surely and firmly, and nevertheless making speed and attending to the game. Once, when we had pushed the herd up the slope of a butte, it made a break to get through a little hog-back. The only way to head it was down a series of rough boulder ledges laid over a great sheet of volcanic rock. The man at the hog-back put his little gray over the ledges and boulders, down the sheet of rock,—hop, slip, slide,—and along the side hill in time to head off the first of the mustangs. During the ten days of riding I saw no horse fall. The animal I rode, Button by name, never even stumbled.

In the Black Hills years ago I happened to be one of the inmates of a small mining-camp. Each night the work-animals, after being fed, were turned loose in the mountains. As I possessed the only cow-pony in the outfit, he was fed in the corral, and kept up for the purpose of rounding up the others. Every morning one of us used to ride him out after the herd. Often it was necessary to run him at full speed along the mountain-side, over rocks, boulders, and ledges, across ravines and gullies. Never but once in three months did he fall.

On the trail, too, they will perform feats little short of marvelous. Mere steepness does not bother them at all. They sit back almost on their haunches, bunch their feet together, and slide. I have seen them go down a hundred feet this way. In rough country they place their feet accurately and quickly, gauge exactly the proper balance. I have led my saddle-horse, Bullet, over country where, undoubtedly to his intense disgust, I myself have fallen a dozen times in the course of a morning. Bullet had no such troubles. Any of the mountain horses will hop cheerfully up or down ledges anywhere. They will even walk a log fifteen or twenty feet above a stream. I have seen the same trick performed in Barnum's circus as a wonderful feat, accompanied by brass bands and breathlessness. We accomplished it on our trip with out any brass bands; I cannot answer for the breathlessness. As for steadiness of nerve, they will walk serenely on the edge of precipices a man would hate to look over, and given a palm's breadth for the soles of their feet, they will get through. Over such a place I should a lot rather trust Bullet than myself.

In an emergency the Western horse is not apt to lose his head. When a pack-horse falls down, he lies still without struggle until eased of his pack and told to get up. If he slips off an edge, he tries to double his fore legs under him and slide. Should he find himself in a tight place, he waits patiently for you to help him, and then proceeds gingerly. A friend of mine rode a horse named Blue. One day, the trail being slippery with rain, he slid and fell. My friend managed a successful jump, but Blue tumbled about thirty feet to the bed of the cañon. Fortunately he was not injured. After some difficulty my friend managed to force his way through the chaparral to where Blue stood. Then it was fine to see them. My friend would go ahead a few feet, picking a route. When he had made his decision, he called Blue. Blue came that far, and no farther. Several times the little horse balanced painfully and unsteadily like a goat, all four feet on a boulder, waiting for his signal to advance. In this manner they regained the trail, and proceeded as though nothing had happened. Instances could be multiplied indefinitely.

A good animal adapts himself quickly. He is capable of learning by experience. In a country entirely new to him he soon discovers the best method of getting about, where the feed grows, where he can find water. He is accustomed to foraging for himself. You do not need to show him his pasturage. If there is anything to eat anywhere in the district he will find it. Little tufts of bunch-grass growing concealed under the edges of the brush, he will search out. If he cannot get grass, he knows how to rustle for the browse of small bushes. Bullet would devour sage-brush, when he could get nothing else; and I have even known him philosophically to fill up on dry pine-needles. There is no nutrition in dry pine-needles, but Bullet got a satisfyingly full belly. On the trail a well-seasoned horse will be always on the forage, snatching here a mouthful, yonder a single spear of grass, and all without breaking the regularity of his gait, or delaying the pack-train behind him. At the end of the day's travel he is that much to the good.

By long observation thus you will construct your ideal of the mountain horse, and in your selection of your animals for an expedition you will search always for that ideal. It is only too apt to be modified by personal idiosyncrasies, and proverbially an ideal is difficult of attainment; but you will, with care, come closer to its realization than one accustomed only to the conventionality of an artificially reared horse would believe possible.

The ideal mountain horse, when you come to pick him out, is of medium size. He should be not smaller than fourteen hands nor larger than fifteen. He is strongly but not clumsily built, short-coupled, with none of the snipy speedy range of the valley animal. You will select preferably one of wide full forehead, indicating intelligence, low in the withers, so the saddle will not be apt to gall him. His sureness of foot should be beyond question, and of course he must be an expert at foraging. A horse that knows but one or two kinds of feed, and that starves unless he can find just those kinds, is an abomination. He must not jump when you throw all kinds of rattling and terrifying tarpaulins across him, and he must not mind if the pack-ropes fall about his heels. In the day's march he must follow like a dog without the necessity of a lead-rope, nor must he stray far when turned loose at night.

Fortunately, when removed from the reassuring environment of civilization, horses are gregarious. They hate to be separated from the bunch to which they are accustomed. Occasionally one of us would stop on the trail, for some reason or another, thus dropping behind the pack-train. Instantly the saddle-horse so detained would begin to grow uneasy. Bullet used by all means in his power to try to induce me to proceed. He would nibble me with his lips, paw the ground, dance in a circle, and finally sidle up to me in the position of being mounted, than which he could think of no stronger hint. Then when I had finally remounted, it was hard to hold him in. He would whinny frantically, scramble with enthusiasm up trails steep enough to draw a protest at ordinary times, and rejoin his companions with every symptom of gratification and delight. This gregariousness and alarm at being left alone in a strange country tends to hold them together at night. You are reasonably certain that in the morning, having found one, you will come upon the rest not far away.

The personnel of our own outfit we found most interesting. Although collected from divergent localities they soon became acquainted. In a crowded corral they were always compact in their organization, sticking close together, and resisting as a solid phalanx encroachments on their feed by other and stranger horses. Their internal organization was very amusing. A certain segregation soon took place. Some became leaders; others by common consent were relegated to the position of subordinates.

The order of precedence on the trail was rigidly preserved by the pack-horses. An attempt by Buckshot to pass Dinkey, for example, the latter always met with a bite or a kick by way of hint. If the gelding still persisted, and tried to pass by a long detour, the mare would rush out at him angrily, her ears back, her eyes flashing, her neck extended. And since Buckshot was by no means inclined always to give in meekly, we had opportunities for plenty of amusement. The two were always skirmishing. When by a strategic short cut across the angle of a trail Buckshot succeeded in stealing a march on Dinkey, while she was nipping a mouthful, his triumph was beautiful to see. He never held the place for long, however. Dinkey's was the leadership by force of ambition and energetic character, and at the head of the pack-train she normally marched.
