"I feel sure I should go to sleep," Tom said, "if I were to lie down like that."
"I have no doubt you would, Tom, but there is no fear with the chief. An Indian never sleeps on the watch, or if he does sleep, it is like a dog: he seems to hear as well as if he were awake, and every minute or two his eyes open and he takes a look round. I would rather have an Indian sentry than half a dozen white ones, unless it is in the open, where there is no tree to lean against, and a man must keep moving."
Hunting Dog threw himself down as soon as he returned to the hut, and was almost instantly asleep. Three hours later he rose and went out, and Leaping Horse a minute or two later returned.
"All quiet," he said; and then after smoking for a short time also lay down.
CHAPTER XII — THE SNOW FORT
The hut was quiet at an unusually early hour, for the men had done a very hard day's work, and felt the strain after the long weeks of inactivity. At daybreak they were up and about, but could remain out but a few minutes, for the cold was so intense that they felt unable to face it until they had taken some hot tea and eaten something. Half an hour sufficed for this early breakfast. Hunting Dog was again left behind by the chief when he started.
"Two eyes enough," the latter said. "Hunting Dog more use here."
The wall of blocks was raised three more feet during the day, as it was agreed to devote all their efforts to this, and to defer the work of thickening it until the next day, for the snow had now been cleared so far from its foot that it could no longer be thrown inside. Though but six feet above the snow level, it was at least three feet more above the level of the rock, and its face was a solid sheet of ice, Tom having, during the two days, made innumerable journeys backwards and forwards with snow-water.
