That time, he made up his mind, would be the next evening. He was well; Sally was thoroughly mastered; and, with a horse beneath him which, he felt, could give even the

gray stallion of Hal Dozier hard work, and therefore show her heels to any other animal on the mountain desert, he looked forward to the crossing of the mountains as an accomplished fact. Always supposing that he could pass Twin Falls and the fringe of towns in the hills, without being recognized and the alarm sent out.

Going back up the road toward the ravine at a brisk canter, he pursued the illuminating comparison between Sally and Dozier's famous Gray Peter. Of course, nothing but a downright test of speed and weight-carrying power, horse to horse, could decide which was the superior, but Andrew had ridden Gray Peter many times when he and Uncle Jasper went out to the Dozier place, and he felt that he could sum up the differences between the two beautiful animals. Sally was the smaller of the two, for instance. She could not stand more than fifteen hands, or fifteen-one at the most. Gray Peter was a full sixteen hands of strong bone and fine muscle, a big animal—almost too big for some purposes. Among these rocks, now, he would stand no chance with Sally. Gray Peter was a picture horse. When one looked at him one felt that he was a standard by which other animals should be measured. He carried his head loftily, and there was a lordly flaunt to his tail. On the other hand, Sally was rather long and low. Furthermore, her neck, which was by no means the heavy neck of the gray stallion, she was apt to carry stretched rather straight out and not curled proudly up as Gray Peter carried his. Neither did she bear her tail so proudly. Some of this, of course, was due to the difference between a mare and a stallion, but still more came from the differing natures of the two animals. In the head lay the greatest variation. The head of Gray Peter was close to perfection, light, compact, heavy of jowl; his eye at all times was filled with an intolerable brightness, a keen flame of courage and eagerness. But one could find a fault with Sally's head. In general, it was

very well shaped, with the wide forehead and all the other good points which invariably go with that feature; but her face was just a trifle dished. Moreover, her eye was apt to be a bit dull. She had been a pet all her life, and, like most pets, her eye partook of the human quality. It had a conversational way of brightening and growing dull. On the whole, the head of Sally had a whimsical, inquisitive expression, and by her whole carriage she seemed to be perpetually putting her nose into other business than her own.

But the gait was the main difference. Riding Gray Peter, one felt an enormous force urging at the bit and ready and willing to expend itself to the very last ounce, with tremendous courage and good heart; there was always a touch of fear that Gray Peter, plunging unabated over rough and smooth, might be running himself out. But Sally would not maintain one pace. She was apt to shorten her stride for choppy going, and she would lengthen it like a witch on the level. She kept changing the elevation of her head. She ran freely, looking about her and taking note of what she saw, so that she gave an indescribable effect of enjoying the gallop just as much as her rider, but in a different way. All in all, Gray Peter was a glorious machine; Sally was a tricky intelligence. Gray Peter's heart was never in doubt, but what would Sally's courage be in a pinch?

Full of these comparisons, studying Sally as one would study a friend, Andrew forgot again all around him, and so he came suddenly, around a bend in the road, upon a buckboard with two men in it. He went by the buckboard with a wave of greeting and a side glance, and it was not until he was quite around the elbow turn that he remembered that one of the men in the wagon had looked at him with a strange intentness. It was a big man with a great blond beard, parted as though with a comb by the wind.

He rode back around the bend, and there, down the

road, he saw the buckboard bouncing, with the two horses pulling it at a dead gallop and the driver leaning back in the seat.

But the other man, the big man with the beard, had picked a rifle out of the bed of the wagon, and now he sat turned in the seat, with his blond beard blown sidewise as he looked back. Beyond a doubt Andrew had been recognized, and now the two were speeding to Tomo to give their report and raise the alarm a second time. Andrew, with a groan, shot his hand to the long holster of the rifle which Pop had insisted that he take with him if he rode out. There was still plenty of time for a long shot. He saw the rifle jerk up to the shoulder of the big man; something hummed by him, and then the report came barking up the ravine.

But Andrew turned Sally and went around the bend; that old desire to rush on the men and shoot them down, that same cold tingling of the nerves, which he had felt when he faced the posse after the fall of Bill Dozier, was on him again, and he had to fight it down. He mastered it, and galloped with a heavy heart up the ravine and to the house of Pop. The old man saw him; he called to Jud, and the two stood in front of the door to admire the horseman and his horse. But Andrew flung himself out of the saddle and came to them sadly. He told them what had happened, the meeting, the recognition. There was only one thing to do—make up the pack as soon as possible and leave the place. For they would know where he had been hiding. Sally was famous all through the mountains; she was known as Pop's outlaw horse, and the searchers would come straight to his house.
