"Look sharp at that twisted tree, near the top of the ridge," said White Otter.
His companions looked in vain. They could find no evidence of any one either in or about the tree which White Otter had designated. They feared that he had been mistaken.
"I do not see any one," declared Sun Bird.
"Well, there is a warrior sitting up there among the branches," White Otter told him. "If you look sharp along that crooked limb you will see him. He is far away, but my eyes tell me that he is looking this way. We must be cautious."
"Yes, yes, I see him!" Sun Bird said, excitedly.
"He must be a scout. Perhaps those riders left him there to watch for enemies. Perhaps it is a war party."
"We will wait and see what he is going to do," said White Otter.
As they were high up, and well sheltered in the timber, the Sioux had little fear of being discovered. They were curious to know what the warrior in the tree was watching for, and they determined to wait until they learned. Then they suddenly discovered a horseman near the spot where the Blackfeet had disappeared. The Sioux felt sure that he was one of the company. He was facing toward the ridge where the warrior was watching from the tree. Apparently aware that the latter had seen him, he dismounted and began to signal with his robe. First he held it directly in front of him between his outstretched arms. The Sioux recognized the signal as the sign for buffaloes. Then he waved the robe up and down several times before his body. It was the signal for many.
"Those men are Blackfeet hunters," declared White Otter. "They have found some buffaloes. That man is telling about it."
In the meantime the warrior had descended from the tree and hurried to the top of the ridge. Then he stooped and raised his robe from the ground. He faced toward the north, and repeated the signals which he had just received. Then both warriors disappeared.
