"We will keep watching until we find out about it," Sun Bird assured him.
As time passed and they saw nothing more, White Otter became uneasy. A disquieting possibility had suddenly presented itself to his mind. It filled him with distrust, and awakened fears for the safety of his people.
"I do not like this thing," he told Sun Bird. "That ridge goes a long ways. We cannot see over it. Perhaps a war party is riding along behind that hill. Perhaps they are going to the lodges of my people. I would like to look over that hill, and find out about it."
"You must not try to do that," Sun Bird cautioned him. "It would be foolish. I believe scouts are watching over there. If we show ourselves they will come after us."
White Otter remained silent. He was worried and perplexed. He believed that what Sun Bird had said was true. Still he knew that if a war party of foes was moving against the Ogalala camp it was his duty to learn of it, and carry a warning to his people. For the moment, however, he saw no way of accomplishing it. The ridge from which he was watching was parallel with the ridge to the westward, and there was a wide expanse of open plain between them. To reach the other ridge it would be necessary to ride out in full sight of any foes who might be watching from concealment. White Otter realized that such a maneuver would be foolhardy. He decided that it would be impossible to do anything before nightfall.
"Yes, my brother, I see that what you say is true," he said, finally. "The lodges of my people are three sun's travel away. It is a long ways. A war party travels slow so that the ponies will be fresh when the fight begins. There is only one thing to do. We must keep watching until it gets dark. Then we will ride over that hill, and try to find out about those people."
"I believe it is the best thing to do," said Sun Bird.
Late in the day, however, they saw something which convinced them that the two horsemen had been part of a clever stratagem to deceive any one who had been watching. An eagle suddenly appeared high over the plain, and flew toward the grove of cottonwoods. It was evident that the bird intended to alight in the timber. The Sioux watched closely. Once above the grove, the eagle set its wings and dropped toward the trees. Then, as it got nearer, it rose and circled far out over the plain. The Sioux were quick to understand the significance of the maneuver.
"Hi, Hu-ya saw something down there among the trees," White Otter cried, excitedly.
"Yes, I believe there is something over there in that place," said Sun Bird.
