“ Fig. 232.
Wall Headers.—When all the studding are in you will need headers above and rails below the windows and headers above all the doors, so that you will have timbers to nail the siding to, as well as for the lathing.
Ceiling Joists.—We are now ready for the ceiling joists, which are, usually, 2" × 6", unless there is an upper floor. These are laid 16 inches apart from center to center, preferably parallel with the floor joist.
It should be borne in mind that the ceiling [Pg 126] joist must always be put on with reference to the roof.

“ In single under-flooring, a common strong lath of oak or fir, about one-fourth of an inch thick, should be nailed against each side of every joist, and of every main timber, supporting the floor which is to be secured. Other similar laths are then to be nailed along the whole length of the joists, with their ends butting against each other. ”
