intendent must consider the eircumstane-
es of pitch and extent of roof surface
draining into the valley, and the slope OF
the valley itself which should determine
the depth which the water will probably
obtain in it. In certain cases, where the
roofs are large, this may be eighteen IN
ches or more in summer showers, and the
only security is to make the valley Hash
ings of corresponding size.
A very common place for a small leak
Is around the ~ehitaneys, where rain or
snow often blow between the bricks and
the flaps of a stepping flashing" The
remedy is a liberal application of elastic
cement between the brickwork and the
metal.
While the ~roofers. are at work, the win
dow frames are being rapidly set in place.
| The casing is often moulded or ornament
ed. If plain, it should be II inches
thick, to prevent curling under the heat
| OF the sun. Its inner edge, projecting
half an inch beyond the face Of the pull
ley-style, is usually made to form one side
Of the channel in which the upper sash
slides, bat it is much better to Increase
the depth of the reveal by inserting a slip,
some tiye-eights or three-quarters OF an
inch wide, changing the position OF the
partine-bead to correspond. 1ndepend-
ent of the improved appearance OF such a
frame, room is thus given for mosquito
nets and blinds. The clapboards are
laid close up to the outer edge Of the cas-
inc, but when this shrinhs, a vertical OPP
ening is left, through which rain pene-
trates, and tarred felt, or still better,
strips OF zinc, must be laid in behind the
easing and adjacent wood. The junction.
OF the clapboards with the top of the cas-
ing must also be protected. Some car
penters do this by lacking a strip OF lead
to the boards Just over the casing, and
turning it down over the edge, but it Is
heater and tighter to rebate the top Of the
casing, If this is done, and the vertical
sides of the casing are grooved into the
head, the sills set to a sharp pitch, one
and a half inches or SO, and grooved I'm
derneath for inserting the clapboards
which come below them, the superintend
ent may he tolerably sure that his build
ing will not show that most annoying o.
defects, leakage around the edges Of the
openings, and the clapboarding may be
commenced at once. Before this, how
ever, the notwithstanding, if any is speci
fed, should have been completed, in or
der that its drying may be favored by the
circulation of air through the open joint:
of the boarding, and notice must be giver
to the plasterers in ample season. The
mode usually considered best is to nal
fillets to the sides of the studs, and latE
on these, so that in theory a double air
span is formed by the outside boarding
the sheet Of back-plastering, and the inne1
plaster; hut in practice it is inconvenlen
to nail fillets in the narrow space between
the ledger boards and the outer boarding
of a balloon frame, or just above the drop
ped girt of a braced frame, and still more
so to nail laths to them, so that thes'
spaces are usually neglected, and the wine
which blows in under the clapboards ane
paper of even the best built house, find
an issue at such joints into the interior.
