The outside of the building, siding or weather boarding, is an
important item, as it is designed to protect the interior from sun,
cold, and storms. It should be watertight, and may be made of various
materials, put on in several ways.
In a house to be used in winter, the first layer should be of wide
ship-lap boards. If put on diagonally it will act as a permanent
bracing, and while this is the better way, it takes more time than
horizontal siding. In either case nail to every stud and timber the
board touches. Begin at the bottom of sill, break joints as the work
progresses upward, and saw ends even with outside of posts.
At all door and window openings bring edges of siding flush with
openings.
This inner siding is to be covered with building paper, door and
window frames set, tin flashing nailed over doors and windows, and
outer covering put on.

Before proceeding with outside sheathing, however, the roof should be
framed and covered.
