Log Cabin House

When cabins were built with the intention of applying siding, the logs were usually hewed on the outside to facilitate the application of the siding. When logs were hewed on the inside as well, they were often covered with a variety of materials, ranging from plaster over lath to wallpaper.

Log cabins were built from logs laid horizontally and interlocked on the ends with notches (British English cog joints). Some log cabins were built without notches and simply nailed together, but this was not as structurally sound. Modern building methods allow this shortcut.
