THE WOODWORK. 51 
Wall-Plates.—The proper sectional form for an ordinary 
wall-plate, to rest on a brick or other wall, and carry the 
lower ends of the rafters direct, as shown, is illustrated in 
Fig. 32. It will be seen that the upper 
surface is bevelled or champfered off 
both inside and out, the inner face being 
both wider and flatter than the outer 
one. The plate is thus bevelled in 
order to throw off all moisture and Fic. 32. 
prevent decay. The outer bevel should be of the same angle 
as the pitch of the roof, as shown. For houses of moderate 
size, say 1O{t. to 15ft. in width, the wall-plates should be of 
din. by 3in. stuff at the least ; 4in. by 3in. will do for small 
structures, but in wide structures (20ft. to 30ft.), or when 
great solidity is required, plates of 6in. by 4in., or even 
larger stuff, are frequently employed. 
The correct form for the upper and lower, or sill, plates, 
where the sides consist in part of glass, is shown in Fig. 33 ; 
the rebate or shoulder, shown at a, may either be worked in 
the stuff, as shown at B, or formed by tacking on a stout 
bead or fillet afterwards, as at a. The groove shown at c 
is provided to prevent any water 
running down the face of the 
Py DAY wall below, or soaking in beneath 
‘a the plate. This must, of course, 
x A overhang the wall about 1jin., 
Fig. 53. as shown in the sketch. The 
upper plate is square in section, as shown at D, with a 
rebate or fillet on the under side. 
When several lengths of plates are required, they should 
be halved together, as shown in Fig. 34, each joint being cut
