half of which is screwed into each part of the pieces to be
joined.

VENEER KEYING.--Fig. 346 illustrates the method of strengthening the
corners of boxes which are made of 1/4-in. or 3/8-in. timber, by securing
the corners with veneer keys. The box is mitred and glued in the usual
manner, and after allowing sufficient time for the glue to set, saw kerfs
are made as shown at _a a_. A piece of thin saw-cut veneer is afterwards
glued into the saw kerfs, and when dry the face is levelled off flush.
This method is often used previous to veneering the face side of the box
with rare veneers, and it is also useful for repair work. Note that the
saw cuts are made at an angle. Small picture frames are sometimes keyed
instead of nailed.

MUNTIN AND SKIRTING JOINT.--In the case of panelled rooms it is usually
necessary to scribe the muntins (or uprights) to the skirting. The method
is shown in Fig. 347. The bead moulding of the skirting is only partly
removed, as indicated, leaving a solid portion to which the muntin is
skew-nailed.

COT JOINT.--At Fig. 348 is shown an interesting joint used largely in the
making of Indian cots. The illustrations indicate how the cross bar and
end bar are mortised into the leg. A turned hardwood peg fits into a
suitably provided hole and locks the tenons, which are dry jointed (not
glued) in position. The head of this peg forms an ornament (A) at the
top of the leg and should fit tightly in position. At B are seen the end
and cross bars in their relative positions when apart from the leg. C
shows the end bar and cross bar when the cot is fixed, but in this
illustration the leg is purposely left out of the drawing for a clear
representation. D shows the joints of the leg portion when the part of
the leg above the line at A is sawn off. The hardwood peg is shown at E.

SIDEBOARD PILLARS, ETC. (Fig. 349).--For economy, sideboard pillars are
sometimes built up as indicated, the "shaft," the "base," and the "swell"
being made up of three distinct pieces. Turned pins are left on the shaft
and the base, and these are secured at the joint by the use of a
double-pointed screw called a dowel screw. This does away with the
necessity of reducing the squares at the top of the wood and thus getting
the turning out of a large piece of wood.

NOTCHED JOINTS.--Fig. 350 is a "notched joint," where two
