sition. The front uprights should be at least 5
feet long.

A simple hanging book-rack is illustrated in Fig. 251. The two vertical
strips are each 4 inches wide, 1 inch thick and 4 feet long. Four
shelves are provided, each 3/4 inch thick, 9 inches wide and 4 feet
long. Each shelf is secured to the uprights by hinges on the upper side,
so as to permit it to be swung upwardly, or folded; and below each hinge
is a triangular block or bracket, fixed to the shelf, to support it in a
horizontal position.

A sad-iron holder, or bookcase, shown in Fig. 252, is another simple
form of structure. It may be sufficiently large to serve as a standing
case by having the uprights at the ends serve as legs, or the uprights
may have holes at their upper ends, by means of which it can be
suspended on a wall. As shown, it is 30 inches long from bottom to top,
and 20 inches wide. The shelves are 8 inches wide. All the material is,
preferably, 3/4-inch stock.

Fig. 253 shows a wood-box, or it may readily be adapted for coal. For
wood it should be 2 feet long, 1 foot 8 inches wide and 1 foot 10 inches
high. It will, of course, be made of such dimensions as to suit the wood
to be stored in it, and both the flat-top as well as the sloping portion
of the top should be hinged, so that the entire top can be opened for
filling purposes.

A pair of parallel bars is shown in Fig. 254. The dimensions of this
will vary, and be dependent on the size of the boy intending to use it;
but a size best adapted is to make the posts 3 feet high, and the
distance between the bars 16 inches. This gives ample room for the
exercises required. The length between the posts along the bars should
be at least 5 feet. The entire structure can be made of soft wood,
except the bars, which should be of hard, rigid wood. The posts can be
made of 2" x 2" material, and the braces 2" x 1". The base pieces, both
longitudinal and transverse, should also be of 2" x 2" material.

[Illustration: _Fig. 257._]

Fig. 255 represents a mission type of writing desk for a boy's use. All
the posts, braces and horizontal bars are of 2" x 2" material, secured
to each other by mortises and tenons. The legs are 27 inches high up to
the table top, and the narrow shelf is 12 inches above the top. The most
convenient size for the top is 2
