each appropriately divided into shelves.

If the economy of time by compression is
great, so is the economy of cost. I think it
reasonable to take the charge of provision for
books in a gentleman's house, and in the
ordinary manner, at a shilling a volume.
This may vary either way, but it moderately
represents, I think, my own experience, in
London residences, of the charge of fitting
up with bookcases, which, if of any
considerable size, are often unsuitable for removal.
The cost of the method which I have adopted
later in life, and have here endeavored to
explain, need not exceed one penny per
volume. Each bookcase when filled represents,
unless in exceptional cases, nearly a solid
mass. The intervals are so small that, as a
rule, they admit a very small portion of dust.
If they are at a tolerable distance from the
fireplace, if carpeting be avoided except as to
small movable carpets easily removed for
beating, and if sweeping be discreetly
conducted, dust may, at any rate in the country,
be made to approach to a quantite negligeable.

It is a great matter, in addition to other
advantages, to avoid the endless trouble and
the miscarriages of movable shelves; the
looseness, and the tightness, the weary arms,
