The doors make a more perfect
separation; but the screen affords more room for storing family
conveniences, and also secured more perfect ventilation for the whole
large room by the exhaust-flue.
Thus, through the week, the school can be in one division, and the
other still a sizable room, and the kitchen be used for teaching
domestic economy and also for the eating-room. Oil Sunday, if there
is a movable screen, it can be moved back to the fireplace; or
otherwise, the sliding--doors may be opened, giving the whole space
to the congregation. The chimney is finished off outside as a steeple.
It incloses a cast-iron or terra cotta pipe, which receives the
stove-pipe of the kitchen and also pipes connecting the two fireplaces
with the large pipe, and finds exit above the slats of the steeple at
the projections. Thus the chimney is made an exhaust shaft for carrying
off vitiated air from all the rooms both above and below, which have
openings into it made for the purpose.
Two good-sized chambers are over the large lower story, as shown in
Fig. 77. Large closets are each side of these chambers, where are
slatted openings to admit pure air; and under these openings are
registers placed to enable pure air to pass through the floor into the
large room below.
