Wrapping buffalo robes round them, Tom and the young Indian went up to the fort. Tom drew aside one of the skins and looked into the shelter. The hearth was in a glow, and two logs lying on it were burning well. The night was very still, except for the occasional rumble of some distant snow-slide. For a few minutes they stood looking over the wall, but keeping far back, so that only their heads were above its level.
"Tom go in by the fire," the Indian said. "All white, no need for four eyes."
"Very well, I will go in first; but mind, you have got to go in afterwards. I sha'n't go in if you don't."
After waiting for a few minutes in the shelter Tom went out again, and Hunting Dog took his place. It was his first war-path, and nothing would have persuaded him to retire from the watch had he not felt sure that even white men's eyes could not fail to detect any dark object moving on the surface of the snow. But although all white the surface was not level; here and there were sudden elevations marking rises in the rock beneath. Still it seemed impossible to Tom that anyone could approach unseen.
In spite of the protection of the buffalo robe it was intensely cold outside, and he was glad each time when his turn came for a warm by the fire. The changes, too, made the time pass quickly, and he was quite surprised when his uncle and Sam came out to relieve them. The other two men and the chief were still smoking by the fire. There was tea in the kettle, and they evidently did not mean to lie down until after their first watch. Every few minutes the chief got up and went out to the platform, and stood listening there intently for a short time. Just before it was time to change the guard again he said when he returned:
"Indian down in valley."
"Have you heard them, chief?"
"Leaping Horse heard a dead stick crack."
"That might have been a deer," Ben suggested.
The chief shook his head. "'Rappahoe; heard gun strike tree."
