"We have no need of it so long as the lake is covered with ice," he said, "and when the ice melts it will be released."
But Dick looked a little farther. The ice might press in on it and crush it, and hence Albert and he cut it out with axes, after which they put it in the lee of the cabin. Meanwhile, when they wished to reach the traps on the farther side of the lake, they crossed it on the ice, and, presuming that the cold might last long, they easily made a rude sledge which they used in place of the canoe.
"If we can't go through the water, we can at least go over it," said Albert.
While the great cold lasted, a period of about two weeks, the boys went on no errands except to their traps. The cold was so intense that often they could hear the logs of Castle Howard contracting with a sound like pistol shots. Then they would build the fire high and sit comfortably before it. Fortunately, the valley afforded plenty of fuel. Both boys wished now that they had a few books, but books were out of the question, and they sought always to keep themselves busy with the tasks that their life in the valley entailed upon them. Both knew that this was best.
The cold was so great that even the wild animals suffered from it. The timber wolves, despite their terrible lessons, were driven by it down the valley, and at night a stray one now and then would howl mournfully near the cabin.
"He's a robber and would like to be a murderer," Albert would say, "but he probably smells this jerked buffalo meat that I'm cooking and I'm sorry for him."
But the wolves were careful to keep out of rifle shot.
Dick made one trip up the valley and found about fifty buffaloes sheltered in a deep ravine and clustering close together for warmth. They were quite thin, as the grass, although it had been protected by the snow, was very scanty at that period of the year. Dick could have obtained a number of good robes, but he spared them.
"Maybe I won't be so soft-hearted when the spring comes and you are fatter," he said.
The two, about this time, took stock of their ammunition, which was the most vital of all things to them. For sometime they had used both the shot and ball cartridges only in cases of necessity, and they were relying more and more on traps, continually devising new kinds, their skill and ingenuity increasing with practice.
