"The Minneconjoux will see that White Otter, the grandson of the great war chief of the Ogalalas, is a man," said Yellow Horse, the medicine-man.

"Yes, he is brave like his father, Standing Buffalo, who has gone on the Long Trail," replied Wolf Robe, as he looked admiringly after his grandson.

White Otter rode away with a light heart, for he was overjoyed at the thought of rejoining his friends. He had never been to the Minneconjoux village, but he knew that it was far to the westward near the great mountains, and as Wolf Robe had carefully described certain prominent landmarks along the route he had little fear of missing his destination. The young Sioux had heard many tales relating to the courage and valor of his distant tribesmen, and he was eager to meet the famous warriors of whom he had heard. He was particularly anxious to see Curly Horse, the renowned Minneconjoux war chief, and Sun Bird's father, Rain Crow, a famous medicine-man.

At midday White Otter came to a great village of the little Underground People, the prairie dogs. He rode slowly between the small earth lodges, and saw hundreds of the eccentric little creatures sitting up to watch him. One old gray-whiskered sentinel chattered shrilly as the pony approached, and finally dove frantically into his burrow. Most of the Underground People followed his example. White Otter laughed at their fright. He stopped his pony and waited for them to reappear. When the gray nose of the cautious old patriarch finally came in sight, the young Sioux called a greeting.

"Ho, you Underground People. Do you see who I am? Ho, you old man. Why do you chatter like a frightened old woman? Come out and call to your people. Tell them that White Otter is their friend. See, at my side is the scalp of your enemy, the weasel. See, on my back is the scalp of your enemy, the wolf. See, in my hair is a feather of your enemy, the great war bird. I am telling you about this so that you can tell it to your children. Now I am going away from here. Keep my words in your heart."

As White Otter rode slowly on his way all the little Underground People came from their burrows, and sat up on the low mounds of earth to watch him. When he looked back and saw them he laughed, and raised his hand in greeting. Then he cantered away and disappeared from sight over a low rise of the plain. He rode until sunset, when he saw the first of the landmarks which Wolf Robe had described: it was a small grove of aspens which he had been told concealed a water-hole.

Although he was still on the hunting grounds of his people, and believed he had little to fear from prowling enemies, White Otter approached the spot with his customary caution. He knew that carelessness had betrayed more than one brave warrior into the hands of his foes, and he determined to run no unnecessary risks. Before exposing himself within arrow range, therefore, he rode slowly around the grove, watching for a sign of concealed foes, and studying the ground for fresh pony tracks. When he had ridden several times around the spot without discovering anything to rouse his suspicions, he drew his weapons, and dropped to the side of his pony. Then he walked boldly toward the trees. He found the grove unoccupied, and as it contained a pool of fresh water he decided to camp there for the night.

It was barely dark, however, when White Otter's fancied security was shattered by a noise which filled him with alarm. Rushing to the edge of the plain to listen, he caught the unmistakable sound of galloping hoofs. The truth instantly flashed into his mind. A company of horsemen were approaching his camp-site. Were they friends or foes? White Otter dared not wait to learn. He realized that safety lay in flight. There was not a moment to spare, for the riders would soon be within bow-shot. Running to his pony, he fastened a buckskin muzzle over its nose, and leaped upon its back. Then he rode cautiously out upon the plain.

After he had gone a short distance the young Sioux stopped to assure himself that the unknown horsemen were continuing in his direction. He was surprised to learn that the sounds had ceased. However, the stillness failed to deceive him. He knew that, like himself, the riders were taking every precaution against a surprise. He believed that the main company had stopped some distance out on the plain to wait until one or more unmounted scouts could steal up to the water-hole to reconnoiter. Fearing that these scouts might circle about the grove and eventually discover him, he turned his pony toward the east and rode slowly away.

White Otter made his way toward a deep ravine which he had crossed a short time before he reached the water-hole. He planned to picket his pony in the ravine, and then hurry across the plain on foot to reconnoiter the camp of the mysterious horsemen. He had not gone far, however, when he heard an owl calling in the vicinity of the pool, and he knew that the scouts who had been sent forward to reconnoiter were calling their companions. The signal was answered by the cry of a coyote on the open plain, and it was evident that the riders were advancing toward the grove.
