Among the latter was a shapely, light-brown or buckskin mare who was grazing peacefully about her precious, buckskin coloured daughter. The little one was asleep on the grass. Her graceful little legs were stretched as far as she could stretch them. Her lovely little head lay flat on the ground. Her fluffy tail was thrown back on the grass with a delicious carelessness.

She was only six months old, but already the very image of her mother. From the white strip on her forehead and the heavy black mane down to the unequal white spots on her two hind fetlocks, she was like her. Only her wiry, delicately wrought little legs seemed somewhat too long for her.

Suddenly the old mare’s head went up high in the air; her grinding teeth ceased grinding as a broken machine comes to a dead stop; and the round, dilated, knowing eyes pierced the slight haze in the atmosphere. The little head on the grass raised just a bit, looked inquiringly at her beloved mother—quite near; then with the innocent confidence of childhood, dropped back again, rubbing the soft fragrant grass in an ecstasy of contentment.

But the old mare continued to gaze intently, standing motionless as a stone. She saw that all the other horses were gazing just as intently as she was. Small moving objects—two men on horseback—had broken over the line of shadow along the southern horizon. One of them was loping away to the right and the other to the left. The old buckskin mare had already lived more than twenty years. Not only had she herself suffered at the hands of man, but she had had so many of her babies taken from her and cruelly abused—often before her very eyes. Her mother’s heart began beating fast and apprehensively.

The other mares, not far from her, also showed signs of extreme nervousness. The buckskin saw them run off for a short distance as if in panic, then stop and gaze anxiously at the approaching riders. It was time to act. She looked questioningly a moment toward the north; but she realised that that direction would soon be closed to her, for she could tell that the riders, loping straight north, meant to turn in time and come back upon them.

She called nervously to her little one. The little thing sprang to its feet, sidled up to her and gazed at the dark specks that were coming together in the north, with fear glowing moist in her large, round eyes.

Until she had seen a group of horsemen dismount, one day, she had thought that man was a monstrous sort of horse with a frightful hump on its back. What little she had been able to learn about him since that time had served only to intensify her fear of him; and despite her abiding confidence in her mother, she trembled timorously as she heard the ominous hoof-beats in the distance.

The animals instinctively gathered into a bunch and started away at full speed. While one of the horsemen remained some distance behind, ready to prevent the group from going off to either side, the other plunged into the midst of them and deftly separated the mothers and their colts from the rest of the bunch. Then they allowed the single horses to run off to the north at their will; while they came together behind the mothers and their colts and drove them southward toward the long line of shadow that lay like a black elongated reptile, below the horizon and parallel to it.

That long line of shadow, which widened as they neared it, was a great canyon which the Red Deer River had cut out of the level plains. From the jaws of the mouth of the canyon, which were a mile or so apart, the floor of the prairies fell away sheer in places, to a depth of a thousand feet. In many spots there were several parallel cuts in the edge of that floor. Where, during the ages, the elements had been unable to remove the loose earth, it lay along the bank in steep hills which rose up from the bottom of the canyon like gigantic teeth, all crumbling more or less, all dotted with stones and covered here and there with blotches of sagebrush and cacti.

In the centre of the flat-bottomed canyon, as if an ancient torrential flood had spent itself and narrowed down at last to a small, shining stream, a quarter of a mile in width, ran the Red Deer River. In the middle of the half-mile wide space between the river and the hills that made the wall of the canyon, stood the buildings of the ranch. The house, a small shingled structure, stood on the east end of the spacious, sandy yard; while opposite and facing it was the long, red barn with its open door below and the gaping window space in the loft above. North of the barn and against its blind wall there was a big corral, divided into two parts by a partition. The corral walls as well as the partition were made of logs laid horizontally, a foot apart and rising to a height of some eight feet. Each of these two sections had huge swinging gates which opened inward.
