II was we'll into 1865 before the FIRST ma
chine press approximauns the present
modern high power speed presses came into
existence. Ia that wear William Bullock oi
Philadelphia, invented the first machine
which printed on both sides Of thc paper
at once and from q continuous web OF
paper.
Since that time the Developments have
followed so rapidly and so nlmerousiy thaJ
thousands OF patents lave been issued ON
improvements of the power press Many
Of these had to do with the cutting. folding

Coincident with this development I'm the
press came improvements in the attendant
processes - stereotyping, engraving htho-
graphing. The stereotype process IS that OF
duplicating in one piece OF type metal the
face of a collection of types composed for
printing This permits Of duplicate forms
being placed simultaneously ON several
presses, thus multiplying the output and
all from the one original type composition.
To explain the process it is necessary only
to follow one particular piece of COPY as
the written matter in a newspaper Office is
termed. The copy goes TO linotype COM
positor. who creates with his machine a
line of matrices. Into these molten type
metal is forced under pressure and a
slug" or line of tvpe in sCId form, is pro-
duced The take of COPY being cast into
typc-slugs, a proof is taken and the
matter is read by proofreaders, corrected,
revised and arranged DO ,ho page as it rs

which is rapidly baked into q solid sheet

prospective press type into matrice form

This papier-mach6 mould is then put into

To look over the development Of the life OF

existence inevitably suggests the question:
