Our surprise vas So great on beholding
the movements of this ingenious and
admirable machinery we thought brief
notice OF it would not be out Of place
in our paper. These presses are the
invention of Mr.. Daniel Tredwel! of
Boston. They may be propelled by a
ny power. The four set up by Messrs
Gales & Ssaton, are moved BY beau
tiiui bigh pressure steam engine Of
bout five hose power. They each strike
OH about Eve hundred sheets an hour.
and each is attended by two girls. one to
supply the paper, and one to take off
| the sheets as fast as they are printed
The pressure is given perpendicularlv
by earn, acting on a togge ieint. and
not on cylinder. The linking apara
tus is peculiar and simple, bus most in
genlous; and the perfect distribution of
the ink, before it is impaired /, the
types, is principal cause of the SUPERB

ihe cost OF the four presses. we under

mount paid TO the patentee for the pri

steam engines about S2onO-- making an
aggregate cost of from $4,000 to
$1,000. The engine consumes about

ihe enterprise originated in the de

congressional printing with yet greater
dispatch and their success, in that res

wonderful rapidity and accuracy with
which the largest public documents are
