wish attended to in the Printing, and with his pen make any words
plain which may happen to be obscure, by doing which, he will frequently
prevent those errors of the Press which often change the sense of a
passage, and are liable to escape detection.

When the Manuscript has thus been prepared, the next step will be the

CHOICE OF PAPER,

that is, to determine on the Size of the Work. This is a question which
will generally be decided by what is customary. If a work of Fiction,
the size will be what is called Post 8vo. If Historical or Scientific,
Demy 8vo. If Poetry, Foolscap, Post, or Demy 8vo. as may be preferred.
There are, however, a variety of other sizes, regulated by the number of
leaves into which the sheet may be folded, as well as by the size of the
Paper adopted, which may be more readily seen than described. The size
and qualities of Paper, are of every variety.

PAPER MAKING.

The Manufacture of Paper, as now used, is not an Art of very ancient
date, probably not earlier than the thirteenth century; but of its
origin nothing is certainly known.

Various substances were in ancient times employed for writing, as Skins,
Ivory, Lead, &c. In Egypt, from a very remote period, the inner films
pressed together of the Papyrus or Biblos, a sort of Flag, or Bulrush,
growing in the marshes there. From whence the word Paper is derived.

Paper is made from Rags, the best from Linen Rags; thus rendering that
which had become useless, an article of universal importance, and
permanent value. Without this indispensable material, Printing would
have been deprived of its chief auxiliary; but with it, and by the
present improved system of Manufacture, the productions of the Press,
and of the Paper Mill, can be carried to any extent.

The Process of Paper Making is thus conducted. The Rags are first
washed; then ground in the Mill with water, so as to form a Pulp; this
Pulp is then conveyed to a Vat, furnished with a Mould of fine wire
cloth, which takes up a sufficient quantity to form the Sheet, which,
when the water has drained from it, is laid on a pile, and pressed so as
to discharge the remaining moisture: it is then hung up to dry, after
which, unless it has been sized in the Vat, which is the case with some
kinds, it is dipped into a tub of fine size; and when again dried and
pressed, is fit for use.

One of the greatest modern improvements in Paper making, is Bleaching
the Rags. This enables the Paper-m
