THE YOUTHS CABINET. is

makes up his matter, that is, he arranges
it in pages. To do this, he ascertains,
by a measure he has, the length of the
previous pages; and takes a sufficient
number of lines from those in the galley
to make one column, or half the page, of
that length. Next, he places a brass
rule perpendicular with the column, and
of the same length with it, which, when
the page comes to be printed, will make
a line of division between the two col-
amns. The next thing to be done, in
the process of making up, is to empty in
another column, parallel with the first.
Then the compositor takes a piece of
twine, and draws it carefully several
times around the page, 80 as to hold the
whole firmly together; after which he
lifts the page from the galley, and places
t on the imposing-stone. This is @
piece of marble, with a very smooth
face, placed horizontally, of sufficient
size to hold some sixteen or more pages
of the CABINET. You perceive, little
friends, that I am proceeding with the
description of the process of printing, as
if the thing to be printed was in the
form of a book or pamphlet. The
printing of a newspaper is somewhat
simpler.

From this point in the process of
printing—the point where the matter is
made up into pages—there is a good
deal of difference in the course pursued
with a work to be stereotyped, and one
which is to bé printed from the types
which the compositor has, sel up- To
avoid confusion, although the CaBINET is
stereotyped, every line of. it, 1 will pro-
ceed with the description as. if it were
printed with the separate types. ‘The
process of stereotyping I will describe
to you by and by.

The pages must be arranged on the
imposing-stone in such, a manner, that.
when the sheet is print , they will fol-
low each other in proper order. This
process is called imposing. ‘The Cast-
net is called a large octayo. Sixteen
pages are printed at once. In other
words, to, employ the language of the
printer—for you are ina printing-otfice
now, and must talk as the printers do—
there are sixteen pages in @ form. So
the man who is imposing these pages,
lays down, sixteen of them, according to
the rule observed in imposing an octavo ;
and if he understands his business, he
will not have to hesitate long about the
particular place each page is to occupy ;
‘¢ he should be ata loss how
to proceed, he could find the plan laid
down in a book, designed as a guide in
all the different departments of the art
of printing. In this book, there are par-
ticular directions given for imposing all
the various forms—folio, quarto, octavo,
duodecimo, and so on,

After the form is imposed, it must be
locked up. -An iron frame is employed
for this purpose, which, when it lies
down horizontally on the stone, is about
two thirds as high as the types. This
is called a chase. You will see a chase
in the engraving of the printing-office.
It is leaning against one of the stands.
The chase is made with two bars run-
ning across it, and crossing each other
at right angles. These bars are not
fastened permanently to the sides of the
chase ; but, provision is made for their
being moyed so as, to fit. the chase for
locking up different, forms. The chase
being laid on the stone, so as to enclose
the pages, and so that they are divided
by the two cross-bars, the next thing to
