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.
The eaves logs, end logs, and ridge logs were soon in place; then came the cutting of small poles, spruce and tamarack, long enough to reach from ridge to eaves, and in sufficient number to completely cover the roof.

A rank sedge meadow near by afforded plenty of coarse grass with which the poles were covered deeply; and lastly clay dug out with a couple of hand-made, axe-hewn wooden spades was thrown evenly on the grass to a depth of six inches; this, when trampled flat, made a roof that served them well.
The chinks of the logs when large were filled with split pieces of wood; when small they were plugged with moss.

A door was made of hewn planks, and hinged very simply on two pins; one made by letting the plank project as a point, the other by nailing on a pin after the door was placed; both pins fitting, of course, into inch auger holes.
A floor was not needed, but bed bunks were, and in making these they began already to realize that the cabin was too small.

But now after a week's work it was done.
