The paper mill. though not a extensive

cient for all the labor reguired in making
the note printing paper. The engine uSc,l
in this room Is a great beauty. clittvTin-
with brass. as highly polished and clean as
the work of watch, and running almost As
! quietly and smoothly.
The manufacture of a paper comlining

The ink mills are six in number. for
making rs many different CoiorS. Each
one is called a four horse power mill. though
the whole six are driven at the same time
by an engine which one could pick up with
one hand. Il not nn,y turn, these mills
but at the same time runs th:CC IF Hoes
cylinder presses. 1t was made in the ma
chine shop of the Department, ami derives
its force from its great boi.cr capacity. OF
the manufacture of the ink hUt little i to

paint shop, has the prscc>S At once. and
perhaps the only difference i that here none

The engraving room Is of more Interest
than any wc have yet ..ccn an. Here sCiUncc
and art are both displayed to perfection.
There is, perhaps, no engraving Su fine and
