The trim is worked out of seven-eighths inch
material, moulded and hollow-backed, and pro-
vided with face-mould, back-band, and small
flexible wall-mould. Joints at angles are mitered
and put together with slip tongues, glued, and
screwed. In the better class of work, the trim is
put together at the carpenter shop; and all sur-
faces, including backs, edges, ends, splines, and
faces, are primed. It may then be brought to the
building without risk of damage through the
dampness in the atmosphere or at the building.
The trim is carried to the floor, and finishes
on moulded wood plinths. The inside recess of
the window is carried to the floor, the masonry
wall being made four inches thinner under the
window. A stool and apron are provided, but-
ting into the jamb linings; and the base breaks

around the recess, thus forming a plaster panel-
back. This plaster panel-back may be painted
or grained to match the adjoining woodwork,
and the effect of a wood panel secured.
The opening in the masonry wall has a stone
sill and lintel, and the inside of the wall is furred
with one-inch by two-inch strips. Grounds Q
are set wherever required for a nailing for the
interior finishing woodwork.
Framing for Casement, Screen, and Blind.
Fig. 100 shows the construction of an inward-
opening casement window in a brick wall, with
insect screens placed outside of the sashes, and
with blinds placed outside of the insect screens.
It is also arranged so that when the screens are
removed in winter, storm sashes may be installed
in their place.
