wall
space. In calculating the length of shelving remember that each _upright_
is five-eighths of an inch thick; and in estimating the height of the
uprights, don't forget to add the thicknesses of the shelves to the
spaces between them. Perhaps the following example will be useful.

To find height of upright:--
Top shelf space 91/2in.
2nd shelf space 10 in.
3rd shelf space 10 in.
4th shelf space 10 in.
5th shelf space 12 in.
6th shelf space 14 in.
Height of lowest shelf from floor 6 in.
Thickness of 6 shelves, each 5/8in. 33/4in.
------
Height of upright--6ft., 31/4in.
------

The top shelf will be 5ft. 5in. from the ground.

The uprights must be two inches wider than the shelves in order that the
latter may not rest against the wall. There must always be a space
between shelves and wall to allow a free circulation of air about the
books. Therefore, let your uprights be eleven inches and your shelves
nine inches in width. In estimating the amount of timber required, don't
forget the top.

The manner in which the shelves are supported by the uprights is as
follows. Strips of wood five-eighths of an inch square and nine inches
long are screwed across the uprights, and on these the shelves rest. So
when you order the wood from your carpenter or timber merchant see that
he sends you also a sufficiency of these strips, two for each shelf.

The fixing of these strips will entail a certain amount of carpentry, and
in addition to bradawl, screwdriver, and footrule you will need a hard
pencil and a carpenter's square, as well as some stout iron screws one
inch long. Two screws are sufficient for each strip. If you are anything
of a carpenter you will countersink the holes for the heads of the
screws; this will also prevent a possible splitting of the strip.

When your carpentering is completed, the whole case must be stained to
your taste. For this purpose our book-hunter has found nothing so good as
the solution known as 'Solignum,' which may be purchased at any
ironmonger's. In addition to being a wood-preservative, it has the
advantage of being obnoxious to insects. It dries a pleasing brown, not
unlike old oak. T
