He soon learned otherwise, as the trail approached the grove from the south. White Otter followed the tracks a short distance out on the plain, and found evidence which convinced him that the pony had carried a rider. As there seemed little to be gained by following the trail farther in that direction, he turned and followed it to the grove.
The camp site was unoccupied, and as there was a spring, and plenty of grass for his horse, White Otter decided to stop there for the night. He picketed his pony, and then began to examine the place for signs. The ashes from a small fire, and some charred bones scattered near by, told him that some one had spent the night at that spot several days before. He worked diligently to find a clew to the identity of the traveler, but found nothing which would tell him what he wished to know. The little mound of ashes, the remnants of a meal, and the pony tracks were his only clews.
The fact that the unknown horseman had come from the south aroused White Otter's interest. Both the Pawnees and the Utes lived to the southward. As he had already encountered a war party of the latter at the grove he wondered if it was a favorite stopping place for those mysterious foes. However, as the signs were at least two days old, the possibility caused him little concern.
Having finished his reconnaissance, White Otter seated himself at the edge of the grove to watch the plain. The sun had already set, and the purple evening shadows were creeping out of the east. The prairie appeared lifeless. The Sioux was at a loss to account for the scarcity of game. He feared that foes of some sort had driven it from the locality. The thought suggested the possibility that the lone rider was a scout, loitering behind a hunting party to watch for enemies.
At dark White Otter returned to his pony. He feared to make a fire, lest the gleam might betray him to his foes. He sat beside the little spring, and ate several cakes of pemmican, composed of dried meat and berries, which he had brought for just such an emergency.
Before he ventured to sleep, White Otter returned to the edge of the plain, and spent a long time listening for a warning of approaching enemies. The howling of some distant prairie wolves, the gentle rustling of the aspens, and an occasional grunt from his pony were the only sounds. He continued to listen, however, until the night was half gone. Then he returned to the camp site, and lay down to sleep.
Dawn was just breaking when White Otter was suddenly awakened by the snorting of his pony. Seizing his bow, he moved cautiously to the edge of the grove. A buck antelope was standing within easy bowshot. It had scented the pony, and stopped to investigate. Unable to resist the temptation, White Otter drove his arrow through its heart. It was a yearling in prime condition, and he cut a choice steak from the carcass. Then, as the light strengthened, and he saw no evidence of foes, he made a tiny fire and broiled the antelope meat. He ate heartily, and gave thanks to Wakantunka, the Great Mystery, for sending him food.
Shortly after sunrise White Otter resumed his journey toward the Minneconjoux camp. As the pony tracks led in that direction he followed them with keen interest. If the lone horseman really were a hostile scout, White Otter knew that to follow him would be the surest and safest way of locating any enemies who might be in the vicinity. He kept a sharp watch, therefore, and approached the knolls and ridges with great caution.
It was midday before he saw anything to make him suspicious. Then he discovered a dense cloud of dust rising behind a slight elevation of the plain. He immediately stopped to watch it. It suggested two possibilities—a herd of frightened buffaloes or a company of horsemen. White Otter longed to peep over the top of the ridge, but he realized that it would be folly to take the risk until he knew what was before him. He knew that hostile scouts might be watching from that spot, and the possibility made him cautious.
"Perhaps some one is hunting buffaloes," he said.
