Half-way down the trail both horse and rider were startled seriously. A riderless horse, saddled and bridled, dashed out of the darkness and galloped across them. Of her own accord Lady Jezebel swung round, and, before Tresler could check her, had set off in hot pursuit. For once horse and rider were of the same mind, and Tresler bent low in the saddle, ready to grab at the bridle when his mare should overhaul the stranger.

In less than a minute they were abreast of their quarry. The stranger’s reins were hanging broken from the bit, and Tresler grabbed at them. Nor could he help a quiet laugh, when, on pulling up, he recognized the buckskin pony and quaint old stock saddle of Joe Nelson. And he at once became alive to the necessity of his journey. What, he wondered, had happened to the little choreman?

Leading the captive, he rode back to the trail and pushed on toward the village. But his adventures were not over yet. At the bottom of the hill the mare, brought up to a stand, reared and shied violently. Then she stood trembling like an aspen, seizing every opportunity to edge from the trail, and all the while staring with wild, dilated eyes away out toward the bush on the right front. Her rider followed the direction of her gaze to ascertain the cause of the trouble. For some minutes he could distinguish nothing unusual in the darkness. The moon had not as yet attained much power, and gave him very little assistance; but, realizing the wonderful acuteness of a horse’s vision, he decided that there nevertheless was something to be investigated. So he dismounted, and adopting the common prairie method of scanning the sky-line, he dropped to the ground.

For some time his search was quite vain, and only the mare’s nervous state encouraged him. Then at length, low down in the deep shadow of the bush, something caught and held his attention. Something was moving down there.

He lay quite still, watching intently. Something of the mare’s nervous excitement gripped him. The movement was ghostly. It was only a movement. There was nothing distinct to be seen, nothing tangible; just a weird, nameless something. A dozen times he asked himself what it was. But the darkness always baffled him, and he could find no answer. He had an impression of great flapping wings—such wings as might belong to a giant bat. The movement was sufficiently regular to suggest this, but the idea carried no conviction. There, however, his conjectures ended.

At last he sprang up with a sharp ejaculation, and his hand went to his revolver. The thing, or creature, whatever it was, was coming slowly but steadily toward him. Had he not been sure of this, the attitude of the horses would have settled the question for him. Lady Jezebel pulled back in the throes of a wild fear, and the buckskin plunged madly to get free.

He had hardly persuaded them to a temporary calmness, when a mournful cry, rising in a wailing crescendo, split the air and died away abruptly. And he knew that it came from the advancing “movement.”

And now it left the shadow and drew out into the moonlight. And the man watching beheld a dark heap distinctly outlined midway toward the bush. The wings seemed to have folded themselves, or, at least, to have lowered, and were trailing on the ground in the creature’s wake. Presently the whole thing ceased to move, and sat still like a great loathsome toad—a silent, uncanny heap amidst the lank prairie grass. And somehow he felt glad that it was no longer approaching.

The moments crept by, and the position remained unchanged. Then slowly, with an air of settled purpose, the creature raised itself on its hind legs, and, swaying and shuffling, continued its advance. In an instant Tresler’s revolver leapt from its holster, and he was ready to defend himself. The attitude was familiar to him. He had read stories of the bears in the Rockies, and they came home to him now as he saw his adversary rear itself to its full height. His puzzlement was over; he understood now. He was dealing with a large specimen of the Rocky Mountain grizzly.

Yes, there could be no mistaking the swaying gait, the curious, snorting breathing, the sadly lolling head and slow movements. He remembered each detail with an exactness which astonished him, and was thrilled with the bristling sensation which assails every hunter when face to face with big game for the first time in his life.
