he dovetail preventing the rail from being
drawn away from the shoulder. The two pieces are shown separate.

[Illustration: Fig. 34.--Mitre Halving.]

At Fig. 34 is seen "Mitred Halving," a somewhat weak joint, but necessary
in mirror frames, etc., where good appearance is required on the face
side (Fig. 28, 6). Its use is obvious if the face of the frame be moulded
with beads or other sections which require to intersect one with the
other. This also applies if the frame be moulded on its face edges.

Fig. 35 is a halved joint with one side of the piece dovetailed (Fig. 28,
8). This joint is used in similar positions to Fig. 33, and rather less
labour is required in the making. The two pieces are shown separate for
clearness.

Fig. 36 indicates the "Halved Joint," the pieces at one end showing a
double dovetail (Fig. 28, 7). This particular joint is seldom used except
for Manual Training purposes. The illustration shows a sketch of the
joint apart.

Fig. 37 is "Oblique Dovetail Halving," one side of the piece being
dovetailed. The joint is used to prevent "racking," and as a cross brace
to framing. It is occasionally made with both its sides dovetailed as
shown at Fig. 33. (For reference, see Fig. 28, 9.)

[Illustration: Fig. 38.--Stopped Dovetail Halving.]

Fig. 38 shows "Stopped Dovetail Halving." In this case the dovetail is
similar to Fig. 33, with the exception that it does not run through the
bottom rail. This is an advantage if the bottom edge of the rail is in
evidence, or if it is required to glue a moulding or hardwood facing slip
on the lower edge. The glue adheres better _with_ the grain than it would
_end way_ of the grain, and if slight shrinkage occurs across the width
of the bottom rail the moulding would not be forced away by the upright
(see example at Fig. 28, 10).

[Illustration: Fig. 41.--Tee Halving Joint.]

The joint lettered B in Fig. 28 is a "Cross Halving Joint" where each
piece runs through the other. Fig. 39 shows this joint separated, and
Fig. 40 shows a similar joint separated where the joint is made edgeways.

Fig. 41 shows a "Tee Halving Joint" w
