Soon afterward White Otter found the ravine, and picketed his pony. Then he climbed to the plain, and set out to spy upon the camp in the aspen grove. As he made his way cautiously through the dark he tried to guess the identity of the people who had driven him from the water-hole. It was possible that they might prove to be a party of Sioux hunters from the Minneconjoux village, but White Otter determined to risk nothing on the chance. He believed it far more probable that they were a scouting party of Crows or Blackfeet from the north who had ventured upon the Sioux hunting grounds to look for buffaloes.
White Otter hurried across the vast star-lit plain with a firm determination to solve the riddle. He realized that to learn what he wished to know he must expose himself to considerable danger, but he was without fear. He had already established an enviable reputation as a warrior, and had passed through many perilous adventures on the war trail.
The young Sioux guided himself by the stars, and soon arrived in the general vicinity of the aspen grove. When he believed that he was within hailing distance, he stopped to reconnoiter. He stood a long time peering anxiously into the dark to catch the glow of a camp-fire, and listening for some sound which would tell him the exact whereabouts of the people whom he wished to see. His efforts were fruitless, however, and he realized that he was farther from the camp than he had supposed. As there was nothing to gain by loitering where he was, he continued across the plain.
White Otter had gone some distance farther, when he was suddenly stopped by the shrill whinny of a horse. It sounded directly ahead of him, but apparently quite far away. Believing that the call had come from the vicinity of the grove, White Otter looked eagerly in that direction. For a few moments he saw only the vast black plain, and the star-studded heavens. Then he caught a gleam of light far off to the westward. It filled his heart with joy, for he knew that he had located the camp. It also assured him that the horsemen had actually stopped in the grove, and he felt greatly relieved. More than once he had been troubled by the fear that the travelers had merely visited the pool to refresh their ponies and had then resumed their journey. However, now that he was certain of finding them in the grove, he was more perplexed than before. He knew that a hostile war party would be almost sure to travel by night, especially when they found themselves in the very center of the Sioux hunting grounds. Therefore, White Otter concluded that these people were hunters either from the Minneconjoux village, or from that of one of the hostile tribes farther to the north.
Having definitely located the camp, the young Sioux determined to approach it without further delay. He knew that to learn the identity of these people he must get near enough to reconnoiter while the light from the fire made it possible to see them. Therefore, he drew his weapons and advanced toward the water-hole. As he finally neared the grove he stopped at the end of every third stride to listen. Then when he heard the ponies stamping restlessly he knew that he was within arrow-range, and he sank noiselessly to the ground. He realized that if these people were enemies they had probably stationed scouts about the grove, and he feared to move lest he might encounter one of the alert sentinels at any moment.
As White Otter lay upon the plain determining the safest way to approach the camp, he heard sounds which led him to suspect that the horsemen were preparing to leave the grove. At the same time he noted that they were placing fresh fuel upon the fire. The maneuver made him suspicious. "These people are not Sioux," he told himself.
Fearing that they would go away before he could identify them, the eager lad rose and hurried toward the grove. Before he had covered half the distance, however, the unknown riders mounted their ponies and rode away at a gallop. They went toward the south, and White Otter felt sure that they were foes.
The young Sioux listened with a heavy heart until the mocking hoof-beats finally died away in the distance, and then he made his way to the little pool. The fire was blazing fiercely, and he felt certain that it had been left to give the impression that the riders were encamped in the grove. Their hasty departure convinced him that the horsemen believed themselves pursued. It seemed as if his earlier fears had been confirmed. These people were evidently retreating from a larger company of foes. The thought made White Otter serious. He wondered if his tribesmen, the Minneconjoux, were involved in the mystery.
However, as White Otter saw no way of learning what he wished to know until he reached the Minneconjoux camp, he told himself that he must be patient. He concealed himself near the pool and waited some time, hoping that a pursuing company of horsemen might soon appear. But the possibility that they might be Crows or Blackfeet caused him considerable uneasiness, and he finally determined to return to his pony and spend the balance of the night in the ravine.
