THE PRODUCTION OF A NEWSPAPER.
Simple as this operation seems in the de-
scription, in reality it becomes a very highly
skilled class of labour, upon which only the
most experienced men are engaged. The
whole appearance of the newspaper depends
upon the arrangement of the different items,
all of which to the novice seem alike, and
the man who can “ make up ” so that every
item of news is given its due importance is
almost an artist in type. When the arrang-
ing of the page is satisfactory, steel blocks
are placed within the frame, a turn is given
with a key and the whole mass of type is
immovably locked together. I he work of
the compositors is done, and the table with
the page upon it is wheeled or taken by lift
to the stereotyping foundry.
Here in one corner a great cauldron of
melted white metal bubbles above the fire
that keeps it hot, while scattered about, in
precise order, are the heavy steel casting
boxes, the machines for planing the metal
plates, and the great press, like an iron
mangle, which is used in making the
matrices. With great rapidity the moulders
cover the face of the type with a sheet of
damp papier-mache, beating it down until
the soft pulp is forced into every nook and
crevice. The process is finished by running
the page through the heavy rolling machine.
The sheet of paper is quickly dried, either
in a hot sand bath or a steam-heated press,
and emerges of almost horny consistency
with every dot and mark of the type deeply
impressed upon its surface. This is the
matrix from which the stereotype plates
are cast.
In the time of the hand press, when
editions were small and printed with great
labour, the impression was obtained direct
from the surface of the type, which rested
upon a flat bed. When the rotary press
with its rapidly revolving cylinders came into
existence, printing from type was no longer
possible. Obviously a mass of loose pieces of
metal could not be made to cling satisfactorily
to the surface of a steel roller. T he solution
of the difficulty was found in stereotyping ;
that is, in casting, from such a matrix as
has been described, a mass of solid metal
with the same circumference as the cylinders
of the machinery.
The way in which this is clone is simple.
The papier-mache matrix, having been pre-
pared, is fixed within a steel box, the
interior of which is curved to half a circle.
