Which side of the outlet? Quonab settled that--the west. He wanted to see the sun rise, and, not far back from the water, was a hill with a jutting, rocky pinnade. He pointed to this and uttered the one word, “Idaho.” Here, then, on the west side, where the lake enters the river, they began to clear the ground for their home. Chapter 20. The Trappers' Cabin It's a smart fellow that knows what he can't do.--Sayings of Si Sylvanne. I suppose every trapper that ever lived, on first building a cabin, said, “Oh, any little thing will do, so long as it has a roof and is big enough to lie down in.” And every trapper has realized before spring that he made a sad mistake in not having it big enough to live in and store goods in. Quonab and Rolf were new at the business, and made the usual mistake. They planned their cabin far too small; 10 X 12 ft., instead of 12 X 20 ft. they made it, and 6-ft. walls, instead of 8-ft. walls. Both were expert axemen. Spruce was plentiful and the cabin rose quickly. In one day the walls were up. An important thing was the roof. What should it be? Overlapping basswood troughs, split shingles, also called shakes, or clay? By far the easiest to make, the warmest in winter and coolest in summer, is the clay roof. It has three disadvantages: It leaks in long-continued wet weather; it drops down dust and dirt in dry weather; and is so heavy that it usually ends by crushing in the log rafters and beams, unless they are further supported on posts, which are much in the way. But its advantages were so obvious that the builders did not hesitate. A clay roof it was to be. When the walls were five feet high, the doorway and window were cut through the logs, but leaving in each case one half of the log at the bottom of the needed opening. The top log was now placed, then rolled over bottom up, while half of its thickness was cut away to fit over the door: a similar cut out was made over the window. Two flat pieces of spruce were prepared for door jambs and two shorter ones for window jambs. Auger holes were put through, so as to allow an oak pin to be driven through the jamb into each log, and the doorway and window opening were done. In one corner they planned a small fireplace, built of clay and stone. Not stone from the lake, as Rolf would have had it, but from the hillside; and why? Quonab said that the lake stone was of the water spirits, and would not live near fire, but would burst open; while the hillside stone was of the sun and fire spirit, and in the fire would add its heat. The facts are that lake stone explodes when greatly heated and hill stone does not; and since no one has been able to improve upon Quonab's explanation, it must stand for the present. The plan of the fireplace was simple. Rolf had been present at the building of several, and the main point was to have the chimney large enough, and the narrowest point just above the fire.
