Therefore, in selecting the material for your proposed house, choose only such trees as are best suited to the strength of the builders. There is no rule which fixes the diameter of a log or pole, so a log-house is a log-house, no matter whether the diameter of the log from which it is built be four inches or four feet. When a log is hauled by men, horses, or oxen, through the woods, it is called “snaking.” The “Skid” is two or more logs laid on the ground, upon and across which the other logs are piled up for use. Common-sense will direct you to select only the timber which comes nearest being straight, and also to cut the logs considerably longer than the length marked on the plan. [Illustration: Happy Days.] Fig. 93 shows the plan of a simple cabin, 6 feet wide by 10 feet long, inside measurement. [Illustration: FIGS. 93 and 94.] Fig. 95 is a rough sketch and plan of two such cabins under one roof, with a hallway, or “gallery,” as they call it in the South, between them. Fig. 96 is a plan of the saddle-bag. In this sketch you will see how your house may be enlarged, at any time, by the addition of a duplicate house, with a roofed space between the two. [Illustration: FIGS. 95 and 96.] First decide upon the exact spot where you intend to Locate Your Cabin, then stake out the cabin according to your plans, and clear the ground for the house. To facilitate rolling the logs as you need them, arrange some skids close by the site of the house, and allow them to slant toward the proposed cabin. If there are any stones handy, Build a Foundation by making a pile of stones a foot or two high, at each of the four corners, in such a manner that the logs resting on these supports will be at the same level at each end, level with each other, and exactly six feet apart. For Floor-Joists take a number of strong poles, and, with a sharp hatchet, give them a flat side for the floor-boards to rest upon, and trim off each end, wedge-shaped, as shown by Fig. 94, the rough sketch at the bottom right-hand corner of Fig. 93. You understand, of course, that The Floor-Supports must be of sufficient length to reach from the front sill-log to the back sill-log. Nail each joist at each end to the sill-logs, and place them about two feet apart. If it is thought that the flooring of the cabin makes too much work, you may build one with a “mud-sill,” by using the hard earth for floor and foundation. Abraham Lincoln lived in a “mud-sill” house, and there are hundreds of such houses in the Southern States. With the exception of the sill-logs, all the logs are notched at both ends and on both sides (Figs. 97 and 98); the sill-logs are notched at both ends, but only on one side, as shown by Fig. 98. Logs of the same diameter as the sill-logs can be laid between them on the bare ground and used for joists, but the best plan is a stone foundation, and a plank floor at least a foot or two above the earth.
