TWO FORTY MINE

Through the courtesy Of the man
agement of the Two Forty Mining.
and Milling company, the Observer
mining reporter was driven to the
mine this morning, and inspected the
hosting plant and the new ten-stamp
concentrating mill, now being erected
and nearly completed.
The ~hoisting plant consists of a
20 h. p. hoist and a 60 h. p. boiler,
enclosed by a lofty and spacious
building 40 by 60 feet, with all the
modern conveniences for handling
ore cheaply and with economy. The
mill, although not large is certainly
a piece of modern art, and is being
constructed under the management of
that prince of mill men, Peter Nc
Farlane, whose motto has ever been,
keep abreast of the times and adapt
yourself to new situations, together
with the advice OF the several mem
bers of the management, WHO are
skilled in mechanical art
feet wide and A feet high, and is
enclosed with sheathing covered with
corrugated iron, with a projecting
cornice painted white, corresponding
with its he'ghth and when building is
completed, will be connected with tire
shaft dump by viaduct. whose tracks
will lead into the UPPER part of the
mill, where the ore is dumped into
the upper crusher, and from there IS
automatic.
The ore from tie crusher is con-
veyed to the different batteries where
stamps pulverize it and then flows
over a double set of amalgamation tab
les, to set of McFarlane bump
ers, where the first concentrates,
are cast off. the residue gliding au-
tomatically TO two Card tables where
the gold, silver lead and zinc are each
separated from the pulp, and the
shines treated by flotation, and af-
terwards passed into settling tanks.
and should any values be found, these
settings are returned for retreat
ment. From the top of the mill to
the settling tanks. everything is au-
tomato, and one man can care for
the whole mill
The ores that are mined through
the tunnel are conveyed by track to
the crusher, located in the lower.part
of the mill. and are elevated after
passing through tie crusher 10 the
stamp floor. where it takes the
course heretofore described.
The mill will be operated by 45
h. p. electric motor, connected with
the transformers. who occupy a tasty
building 10 by u feet. some 60 feet
away from the mill Above the
transformer house. at an elevation
equal to the top of the' MILL are three
huge tanks. feet high. by IL feet
in diameter, capable of holding 10.-
900 gallons. that will he filled by
pumping the water from a large
spring. The mill will be completed
and ready for operation by the tenth
of September.
Everything about the mill and sur
roundings, have been conceived for
economy of labor, and the tightening
of treatment charges. and when ev-
erything is complete. will be the
most modern mill of the county, and
too much praise cannot be given the
management and contractor.
There are thousands of tons of
concentrating ore already broken in
the Slopes of the mine, ready for
treatment as soon as the mill is
complete, and with its large bodies
of high grade smelling ore already
exposed The Two Forty mine will
soon be one of the leading shippers
of the county. as II is connected with
the Gilpin tramway, and all ores of
whatever nature. can be transported
TO ready market without extra cost.

insurance inspector for Colorado, ac-
companied the party.
