cranks, and they have thus been con.
verted into solid wheels, to which brakes
are attached. Brakes are also attached
to the two reels, so that the whole ap-

reels have Bshr's indicators attached to
them, 10 that at all times the place oil

aetly known.
In order to give this engine o firm
foundation, an excavation was made in
the solid rock 60 feet long, 80 feet wide
and % feet deep. the anchor bolts
placed and secured by 1000 perch OF
rubble and $500 feet OF hswn Stone and
coping, upon which the engine bed rests.
Some idea OF the power OF the engine
and hrmnsss Of its foundation may DO
gained from the fact that the shaft and
reels and rope weigh 100 tons, and yet
no lar il felt when this immense weight
is in motion. In fact, but for the slight
rumbls Of the parts, one with his BACK
to the engine could not tell that 1t was
moving.
The pumping engine Is . compound,
condsnsing engine, d~reet.acting, with .
capacity OF 10 strokes per minute. The
initial cylinder has q diameter OF "a
inches, stroke OF six feet nine inches
and weighs 80 tons. The expansion
cylinder has q diameter OF 100 inches, q
stroke OF eight feet three inches and
weighs 43 tons.
These cylinders are jscketsd, the
jacket OF the expansion cylinder being
in two pieces for convenience OF
handling. The cylinders stand In n
inclined position and each takes direct
hold OF the main beam below. Tbs
soleplatss for these cylinders weigh 81
tons each. The ~pistonrods are fitted
with adjustable gearing for setting up
the glands. The pistons are 10 inches
thick. The engine Is fitted with
O'Nsill's improved valve motion. al the
valve gear being in q very compact form
between the cylinders.
Beneath the engine Is the beam, the
center being "a feet 2 inches below the
foundation OF the engine. 1t was made
in sections and OF boiler plate, Hanged
and ribbed to give 1t strength. It is AZ
feet between csnters, with adouble truss
running clear around 1t. The castings
connected with the beam and which hold
this truss, weigh. on each side, 10 tons.
The beam Is supported by q shalt ~
inches in diameter in the center. The
sole plates for the journals are IL feet
long, 20 inches wide and 6 inches thick.
The pillow blocks are brass.lined, ~
inches in diameter in bore. and % inches
long.
The fy wheel sets back Of the engine
and to the right. It is carried by a shaft
"a inches 10 diameter. Is made OF IL sec.
tons, il 40 feet in diameter and weighs
ITO tons. The hub weighs 10 tons and
the pillow blocks 8 tons each. The shalt
of this fly wheel il connected to the
main beam by q rod "a feet long and q
vrought.iron crank giving l2.foot stroke.
On the opposite end Of the shaft iss
wrought.iron crank giving G.foot stroke,
which drives the air pump OF the engine.
To the right Of the engine are the air
pump aud condenser, standing In an
upright position. The air pump is4
feet @ inches In diameter and has .
stroke OF Q feet. The condenser Is a
feet 8 inches in diameter. The exhaust
from the engine to the condenser 10 20
inches in diameter. The air sump and
condenser stand in . cast.iron tank,
which will be filled with water and seal
all the joints, to prevent any air
leaks. This tank 10 IA feet 8 inches
high. - feet 6H inches long, and y fest
6H inches wide.
The pump rod 10 composed Of timbsrs
16 inches square. connected to the beam
BY two immense wrought.iron straps.
gibs and keys, and the sticks are secured
together by four strapping plates, each
80 feet long. 10 inches wide and an inch
thick, bol,sd with bolts IL inches in
diameter. The balance bobs in the shaft
are placed about 400 feet apart. The
whole apparatus Is calculated to operate
a double line OF l4-inch plunger pumps
Of l0.foot stroke to q depth OF 1000 feet,
and q 20.inch Lift pump, "a feet long, to
DO used In sinking. The sinking pump
column Is q lap tube % inches
in diameter, which il the largest ever
made for pumping purposes. These
pumps and the engine are capable oil
raising 2.OOO,O 900 gallons Of water per
day.
This engine has been placed on foun.
dations ss massive and solid as itself.
For its reception . pit IS feet long. 80
feet wide and 40 feet deep was dug into
the solid rock. and 5000 perch OF rubble
put in and 1000 feet OF ashlar and cop
ings laid. The cost OF the stone itself.
which went into the foundation for this
engine was S23. 900. and this did not
include the laying Of the foundation.
In order to ascertain the amount OF
iron, steel aud brass, which has gone
into the Union works In the shape oil
machinery, pumps, etc., shipping bills
have been consulted by the writer and
six pages Of figures summed. The total
on which freight was paid was 2,9il, 622
pounds. To this must be added at least
l5O tons purchased here, making q total
OF $3.50, 900 pounds in round numbers.
In conclusion, 1t Is only necessary to
state that the engine abovs.dsscribed. a.
we'll a. the works and machinery, have
not been placed thers for present pur-
poses only. They are intended to stay,
and in q hundred years from now that
pumping engine will DO a. good, II not
better than 1t is nov.
The Union works are reached by q
switch OF the Virginia aud Truokee rail.
road from the main extension OF the
track to the Ophir. This makes them
convenient Of access with supplies. In
fact, without this convenience 1t would
have been next to impossible to have
handled the heavy machinery above dc.
scribed.
Another switch OF the railroad runs to
the ore house, which has such an sleva.
ton that cars are loaded by opening
chutes leading FROM tbs bottom.
The works are beautifully located on
