"Well, we know that our enemies are in this place," Sun Bird told him. "Now it will be useless to look for the buffaloes. If Ta-tan-ka comes, those scouts will tell their people about it. Yes, I believe they are looking for buffaloes."
"My brother, I feel different about it," said White Otter. "Perhaps those scouts are with a war party. Perhaps they are Pawnees. Perhaps they are going to fight my people. I must find out about it."
Sun Bird remained silent. It was not the part of a warrior to ask questions. He waited for White Otter to explain his plans.
"Now I will tell you what I propose to do," White Otter told him. "We must stay here and watch. Perhaps those scouts are trying to fool us. Perhaps they are trying to make us believe they have gone away. I believe they are peeping over that hill."
"Well, they will not catch us," laughed Sun Bird.
While White Otter continued to watch, Sun Bird crept down the slope to tell Little Raven about the two mysterious horsemen. The ridge to the westward was far away, and White Otter knew that it would be impossible to discover any one who might be hiding there. He had little doubt that at least one of the unknown riders had stopped to watch the plain.
"Did you see anything?" Sun Bird inquired anxiously, when he returned.
"No, I did not see anything, but I believe some one is watching over there on that hill," White Otter told him.
"Then we must be cautious," said Sun Bird.
They watched until the day was half gone, and then, having seen nothing to indicate that foes were loitering in the vicinity, they began to feel somewhat reassured. They wondered if the two horsemen might not have been stray hunters who had been led to the grove by the antelopes. Having found the fresh pony tracks, they might have feared to loiter in the locality. In spite of the possibility, however, the Sioux resolved to take no chances.
