e sides take
the place of the supports, and the back is often reduced to strips
merely wide enough to give rigidity.

The shelves may be either gained into the supports, Fig. 266, No. 28
or No. 29, p. 179, or a keyed mortise-and-tenon may be used, Fig. 277.
In the latter case the back strip may have a short barefaced blind
tenon which is mortised into the upright, Fig. 278. It also fits into
a rabbet on the upper back side of the shelf. Made in this way the
shelves can be knocked down easily.

_Foot Stool or Cricket_, Fig. 279. The grain of the supports should
run up and down, because pieces with the grain horizontal would be
likely to break under pressure. Braces or a rail give additional
support. The top should not be larger than the base of the legs;
otherwise a person standing carelessly on the stool is in danger of
being upset.

_A Drawing-Board_ is made up of narrow boards, with glued joints, with
the boards so laid that the annual rings will alternate in direction,
Fig. 280, _a_. It must be made so that it can shrink and swell and yet
remain flat. For the purpose of giving lateral stiffness cleats are
added. They may simply be screwed on the underside, the screw holes
being large enough to allow for shrinkage, or they may be dadoed in
with a dovetail dado, Fig. 280, _b_, or they may be grooved to admit
a tongue on the end of a board, Fig. 280, _c_. In this case screws
passing thru large holes in the cleats hold them in place.

Screwed on Beneath; _b._ With Cleats Dovetail-Dadoed in; _c._ With
Cleats Matched on Ends.]

_Taborets._ The term taboret originally meant a little tabor or drum,
and was therefore used to designate a small stool, the seat of which
consisted of a piece of stretched leather. The term now includes
small, tablelike structures for holding flowerpots, vases, etc. It
might more properly be called a "table-ette."

When made up with boards having their long edges mitered, it has from
four to eight sides. A six-sided one is shown in Fig. 281. In making,
it is best to fit the joints exactly first, while the board is stiff,
and then to cut out the pattern of the legs. Directions for gluing are
given on p. 169.
