also three large pulp engines, each capable of
holding 900 pounds of pulp. also two S4-inch wet
cylinder cleaning machines, capable of cleaning from
$1,000 to 30UOO pounds OF pulp. There is also in this
room the bleach mixing apparatus, which is quite
important auxiliary in the manufacture of chips into
paper. The whole of the machinery of this building
is driven by two large Turbine water wheels.

power obtained by the new machinery which they in

hardest metals pliabe clay in the hands OF the

leave upon the bars drawn through them the impress
of the figures which they bear.
Instead of solid rolls turned with grooves and peri
pheries in the ordinary manner the inventor uses
the cast wrought iron spindes on which are
slipped cast iron steel rings discs forming grooves
