THE WOODWORK. 57 
These angles can be obtained either from the working plan, 
if on a sufficiently large scale, or a first pair of rafters may 
be cut and fitted to the plates and ridge exactly, 
and the mitre-box be made from these. WY 
When nailing in the bars a guage should be used - 
to keep them at the exact distance apart to take \ 
the glass easily, yet without too much play. A = 
bit of plain lath or bead will do, and it should be Fie. 42 
cut to a bare 1-16th of an inch longer than the exact width 
of the glass. This will allow of the latter going in just right, 
if each bar is pushed up tight to the gauge top and bottom. 
Only those who have tried it can know the trouble and 
nuisance it is to put in glass with bars tin. to in. too far 
apart, and when done it is almost sure to leak badly. 
The bradawl must be used in both ends of the bars before 
nailing, otherwise they will probably split, the smaller sizes 
in particular. 
The end-rafters, which are usually 
made a little stouter than the rest, 
are worked to the section shown at 
Fig. 42. 
Next, the construction of the 
eaves, and the manner in which the 
drip-water is carried into the gutter, 
needs some amount of consideration. 
Ot course, where framed lights or 
sashes are used, the lower edge of 
the bottom rail is projected 2in. or

3in. beyond the plate, and from it the water drips directly 
into the gutter ; but where only glass and bars are employed 
an arrangement of some kind is necessary. The lower edge
