          THE PRINTER.
  In this business there aj'e two kinds of
workmen employed.    Compositors, who
range and dispose the letters into words,
lines, pages, &c. according to the copy before
them in certain portions, the manuscript
being on those occasions divided for the sake
of expedition; and the pressmen, who ap-
ply ink to the same, and take off the im-
pression. The letters, or types, are made
of mixed metals, and are disposed in cases
with separate divisions, called boxes. When
the compositor fills his composing stick, he
empties it into a frame of wood, called the
galley; when a page is formed, itistied up;
and when all the pages are ranged in order,
they are fastened together in a frame, called
a chase, with wedges of wood; this is called
imposing.  There are two forms required
for every sheet. As mistakes will occur, a
sheet called a proof, is printed off and given
to the corrector of the press; who examines
it, while a boy reads the copy to him. It
order to make these corrections, the com-
positor unlocks the form, by loosening the
wedges or quoins; and w hen corrected, the
form is again fastened, and a revise sent to
the corrector. The pressman is assisted by
another to ink the form.
