A second moulding mill, with its two hun
dred different bits, also struck our attention
The demand on the factory for mouldings being
greater than a single mill can supply, though
one will do more work of the kind than any
hundred mechanics working by hand could
possibly turn out. Their mortising machneis
the patent of Ball 4 Ballard, of Worcester,
Mass, and beautiful thing, in its way, it is.
The machine, however, that struck US most
particularly was Smiths patent blind norris
ing machine, a very remarkable implement in
its way Lebanon, y. H.. enjoys the honor of
having produced il. 1t occupies very little
space, and does its work by the operation of
single wheel Of two feet in diameter, which con-
meets directly with the driving wheel by means
of cogs on its outer periphery, which is mar
row one. 1t has an inner and broader peri
phery-or a wheel within wheel. In the
broad periphery are cams for about two-thirds
of its diameter, regulated (raised) as to drive
the "bits" an eighth of an inch deeper into the
"stock' at each succeeding plunge or thrust.
Two connected rods, regulated in their motions
by the cams, drive the chisel, which is in two
parts. One set Of the cams ION one side Of the
wheel driving the upper, and the other set on
the other side of the wheel driving the lower por
ton of the chisel-the halves Of the chisel
operate alternately, except at the last stroke,
when they strike together. The inside of the
cutting portion Of the chisel halves are roughed
or Tipped, 50 as to draw the core from the NOR
tise. An eccentric on the main wheel works
the feed rack. which is drawn a fixed distance
forward with each revolution Of the wheel, by
the operation of a small ratchet. A clamp
worked by another eccentric and connecting
rod on the other side of the machine seizes the
stock on the rack at the precise moment it is
brought to the proper position for the COM
mencement of the operation of the chisel, and
holds it firmly in its iron grip the precise time
necessary to perfect the mortise, when it lets
1T loose to pass on, and again seizing it at the
right time to perfect the operation of making
the next mortise. 1t will work stuff in any
length, from one loot to one hundred feet.
The beauty of this little machine is in the
many complicated effects it produces, each
with mathematical accuracy and great rapid
ty 1t is next to intelligence itself, as it were,
in its operations, 'and demonstrates the won
derful results of the application of mathemat-
ical principles to the supplying the mechanical
wants of man with directness and clearness,
which must be seen to be appreciated, fer it
cannot be satisfactorily described with the pen.
Wright's scroll saw, which they use, is also a
beautiful machine, as well as a machine for
tenoning Stats for pivot blinds, which cuts the
tenon on both ends at one operation. it cuts
by circular saws, the stock being inserted in a
gauge which regulates the diameter Of the
pivot. The saws cut with perfect Justice"
There are four saws operating to finish each
tenOn, and each of them performs its allotted
work, which is different from the work per-
formed by any other saw of the machine; one
cuts the shoulder, the next two round the
pivot pin, and the outer one cuts it of to the
proper length. Of course this machine works
with great rapidity.
machine for boring pivot blind holes, to
be seen there, is also a matter of no little in
forest. 1t works sixteen augers at one time,
each Of which is geared by belt on common
drum as many of the augers as are required
may be worked at one time.
We noticed, by the by, a large lot of their
pivot blinds being finished for Willards' hotel.
These blinds embrace great improvements over
anything of the kind manufactured until very
recently. They are really beautiful to look
upon as we'll as remarkably cheap and conve-
nient We believe the brothers Willard have
ordered them for the whole of their immense
house, or that portion now in use as well as for
the addition they are constructing.
The third story of their establishment is used
as finishing shop wherein the machine made
work is put together by hand In that depart

the triumph Of art and science in this country

means to visit the factory of Baldwin Brothers
which, in all its machinery and other arrange
ments, is behind no other similar one ia this
country in its capacity to execute orders of
every variety instantly with mathematical &C

A NEW ROUTE To THE PACIFIC SIDE.-The
discovery of gold in the Frazer river country
has already brought to light the fact that there
exists route to the Pacific side hitherto ut
terly unknown to ninety nine in hundred of
the people of the United States, which offers
more facilities for overland emigration than
either route travelled up to this time-a route
of inland water carriage, for the most part,
with but a few hundred miles in its whole
length upon which steamboats, cannot ply with
speed and convenience to the traveller.
AS matter of public interest, we quote from
New York Tribune the following description
of the route in question and its attributes:
The new route which II is proposed to open
from Minnesota to the Frazer river gold mines
would appear to be very feasible. 1t would seem
to present not only much the shortest, but, as
soon as the proposed arrangements shall be COM
pleed, the easiest means Of reaching the new
gold fields. From st Anthony, the Mississippi

Rapids. Thence to Breckenridge, at the head
Of navigat of the Red river of the North, is a
distance OF l25 miles. This part of the journey
must be made over land, but already this di striT
