oTYPING PRocEss-THE BULLOCK PRINT
ING PREss.-The most wonderful of all
modern institutions is the daily newspaper.
1t is photograph Of the shifting scenes of
the world taken fresh every day. 1t is the
grand reservoir into which are poured the
events great and small, which 60 to make
up the sum of the worlds history. It is the
cheapest Of all saleable articles. The man
who filings il down with "Poohl there's
nothing in it," if he does not find the record
ola particularly startling event,lis guilty of
a piece Of absurdity that cannot be sur
passed. Let him reflect for moment upon
the enormous amount Of labor necessary to
prepare one single issue Of the pa
per he so CONTEMPORARY casts aside
of the outlay Of money requisite to lay those
bits Of information before him-more, per-
haps, than he will expend in purchasing pa
pers in all his life. Let him reflect that all
the appliances Of art and science-the tele-
graph, the steam engine, and the printing
press-are brought into play to give him
information; that editors, reporters and cor
respondents, all eudgel their brains for his
benefit; that forty or fifty men have worked
long and hard in order to give him his ten
cents worth, end il he be not convinced, he
deserves to be deprived of the sight of a
newspaper during the period of his natural
existence.
A great many Of the Northern aud East
ern dailies, require from one hundred to
two hundred persons, in the various depart
ments.
The circulation Of number Of them has
become so large as TO necessitate the stereo-
tipping Of the forms, and bringing into re-
QUESTION presses that print 10000 in an
hour, and turn out six papers at a time.
The forms are stereotyped for thepurPOse Of
saying the type, and in order to curve the
plate to fit the revolving cylinder of the
press.
The process OF stereotyping is simply
this: The forms are laid upon table and
covered with a thick sheet Of papier mdche,
which is beaten and pressed upon the type
until full and correct impression of it is
left upon the mould. This is then baked
until the heat Of the type hardens the paper
pulp. when II is removed. This is called the
matrix, and is placed ina cCncave mould
with a close fitting lid, and melted type
metal is poured in upon it, receiving the
impression, and becoming an exact dupli-
cate Of Che type but in one hard block, and
in convex form to fit the press cylinder.
The curve, of course varies with the
kind Of press used. The curve required for
the celebrated Bullock Press is a perfect cy-
Under. This press is a marvel Of mechani-
cll ingenuity and skill. It is little ma
chine, about one-fourth the size Of the Hoe
Press, yet it prints 10000 papers ION both
sides an hour, and does away entirely with
manual labor. Both the inside" and "out-
side cylinder plates are placed in il at the
same time, with blanket above each forthe
type to press the paper against. The paper
to be printed is on a continuous roll.
II is "wet down" by being unwound from
one roller and rapidly wound upon another
by machinery, while thin spray of water
plays upon it, moistening the whole mass
Then one end is placed in the Bullock Press
the crank is turned, and the machinery be
gins its work--printing bOtA sides Of the pa
per at once cutting each of at exactly tbs
right length, and turning the printed sheet
out with lightning rapidity upon the plat
form. The sheets for all other presses hav,
to be cut at the mill before they are brough
to the press room.
