whole of the weight to
be carried by the screws as would be the case in _a_, Fig. 237. The
method of sinking each portion of the hinge into the door and carcase
respectively is costly; hence it is not the general practice in cheap
work. In Fig. 239 the top and bottom of carcase (T and B) are shown set
back to allow the door to close.

OUTSIDE HINGEING.--Fig. 240 illustrates the portion of a door frame and
carcase end when the door is hung on the face of the carcase. The correct
method of letting in the hinge is shown in the enlarged section (Fig.
241), but, as previously mentioned, the hinge may have its entire
thickness let into the door frame where it is of a light character. The
door frame projects slightly over the carcase end, and occasionally a
bead mould is worked on the edge of the door so as to give a finish and
partly hide the joint. The bead would, of course, be the same size as the
diameter of the knuckle of the hinge; and the knuckle, therefore, will
form a continuation of the bead and give a workmanshiplike finish.

FALL FRONTS.--Fig. 242 is a sectional view of a fall front writing bureau
fitted with centre or pivot hinges and arranged so that the edges form a
stop when the desk front is turned to a horizontal position. The position
for the fitting of the brass plates carrying the pivot-pin is somewhat
awkward; but, by first sinking the plates into the carcase ends, and then
slotting the edges of the fall, it will be found that the fall front may
be put in from its horizontal position, and that sufficient room is left
to enable the screwdriver to be manipulated without inconvenience.

FLY RAIL.--Fig. 243 is a sketch of a small table with the top removed. A
revolving fly rail is shown pivoted upon a piece of 1/4-in. wire. The
object of this fly rail is to form a support to the small hinged
drop-leaf of the table. This method is suitable for small occasional
tables and similar articles.

DRAUGHT SCREENS.--Fig. 244 illustrates the end elevation and plan of a
draught screen which is constructed of a light framework and covered with
baize or American cloth. The reversible double-folding hinge (Fig. 230)
would answer admirably for such a screen. Cases occur, however, where it
is desired to hinge a screen to
