Sometimes it is feasible to take advantage of a portable mill to face the
logs on three sides rather than to hew them by hand. The level beds seat
the logs so well that calking is minimized, the smooth interior surfaces
permit of easy finishing, particularly where wood wainscoting or plaster
is used, while the round-log exterior effect is undisturbed, except where
the logs project at the corners. Figure 28 illustrates a structure built
in this way.
