the flue behind the corner braces right up to the roof. The top corner-piece carries the rafter that may be cut off to let the flue out. Build the chimney up outside as high as the highest part of the ridge.
But the ideal fireplace is made with the chimney on the outside of the cabin, at the middle of the end farthest from the door. For this you must cut a hole in the end log, like a big, low window, pegging a jamb on the ends as before.
With stones and mud you now build a fireplace inside the shanty, with the big chimney carried up outside, always taking care that there are several inches of mud or stone between the fire and any of the logs.
In country where stone cannot be found, the fireplace is often built of mud, sustained by an outside cribbing of logs.
If the flue is fair size, that is, say one quarter the size of the fireplace opening, it will be sure to draw.
The bunk should be made before the chinks are plastered, as the hammering is apt to loosen the mud.
Cut eight or ten poles a foot longer than you need the bunk; cut the end of each into a flat board and drive these between the long logs at the right height and place for the bunk, supporting the other end on a crosspiece from a post to the wall. Put a very big pole on the outer side, and all is ready for the bed; most woodsmen make this of small fir boughs.
There are two other well-known ways of cornering the logs—one is simply flattening the logs where they touch. This, as well as the first one, is known in the backwoods of Canada as hog-pen finish. The really skilful woodsmen of the North always dovetail the corners and saw them flush: (Fig. 10.)
Sometimes it is desirable to make a higher gable than that which one ridge log can make. Then it is made thus: (Fig. 11.)
This is as much slope as a clay roof should have; with any more, the clay would wash off.
This is the simplest way to build a log-cabin, but it illustrates all the main principles of log building. Shingle roofs and gables, broad piazzas outside, and modern fitting inside, are often added nowadays in summer camps, but it must be clear that the more towny you make the cabin, the less woodsy it is, and less likely to be the complete rest and change that is desired.
