He noticed presently a gray quality in the air, and as he glanced off toward the west, he saw that the red sun was burning very low. Dick's heart sprang up in gladness; it was the twilight, and the blessed darkness would bring chance of escape. Seldom has anyone watched the coming of night with keener pleasure. The sun dropped down behind the swells, the gray twilight passed over all the sky, and after it came the night, on black wings.
Fires sprang up on the plain, fires of buffalo chips lighted by the Sioux, who were now busy skinning and cutting up the slain buffaloes. Dick saw the fires all about him, but none was nearer than a hundred yards, and, despite them, he decided that now was his best time to attempt escape before the moon should come out and lighten up the night.
He pulled himself painfully from the kind gully. He had lain there hours, and he tested every joint as he crept a few feet on the plain. They creaked for a while, but presently the circulation was restored, and, rising to a stooping position, with his rifle ready, he slipped off toward the westward.
Dick knew that great caution was necessary, but he had confidence in the veiling darkness. Off to the eastward he could see one fire, around which a half dozen warriors were gathered, busy with a slain buffalo, working and feasting. He fancied that he could trace their savage features against the red firelight, but he himself was in the darkness.
Another fire rose up, and this was straight before him. Like the others, warriors were around it, and Dick turned off abruptly to the south. Then he heard ponies stamping and he shifted his course again. When he had gone about a dozen yards he lay flat upon the plain and listened. He was hardy and bold, but, for a little while, he was almost in despair. It seemed to him that he was ringed around by a circle of savage warriors and that he could not break through it.
His courage returned, and, rising to his knees, he resumed his slow progress. His course was now southwesterly, and soon he heard again the stamping of hoofs. It was then that a daring idea came into Dick's head.
That stamping of hoofs was obviously made by the ponies of the Sioux. Either the ponies were tethered to short sticks, or they had only a small guard, perhaps a single man. But as they were with the buffaloes, and unsuspecting of a strange presence, they would not detail more than one man to watch their horses. It was wisdom for him to slip away one of the horses, mount it when at a safe distance, and then gallop toward the mountains.
Dick sank down a little lower and crept very slowly toward the point from which the stamping of hoofs proceeded. When he had gone about a dozen yards he heard another stamping of hoofs to his right and then a faint whinny. This encouraged him. It showed him that the ponies were tethered in groups, and the group toward which he was going might be without a guard. He continued his progress another dozen yards, and then lay flat upon the plain. He had seen two vague forms in the darkness, and he wished to make himself a blur with the earth. They were warriors passing from one camp fire to another, and Dick saw them plainly, tall men with blankets folded about them like togas, long hair in which eagle feathers were braided after the Sioux style, and strong aquiline features. They looked like chiefs, men of courage, dignity, and mind, and Dick contrasted them with the ruffians of the wagon train. The contrast was not favorable to the white faces that he remembered so well.
But the boy saw nothing of mercy or pity in these red countenances. Bold and able they might be, but it was no part of theirs to spare their enemies. He fairly crowded himself against the earth, but they went on, absorbed in their own talk, and he was not seen. He raised up again and began to crawl. The group of ponies came into view, and he saw with delight that they had no watchman. A half dozen in number and well hobbled, they cropped the buffalo grass. They were bare of back, but they wore their Indian bridles, which hung from their heads.
Dick knew a good deal about horses, and he was aware that the approach would be critical. The Indian ponies might take alarm or they might not, but the venture must be made. He did not believe that he could get beyond the ring of the Sioux fires without being discovered, and only a dash was left.
