the vein are very numerous. In these,
narrow stresks Of extremely high grade

that these veinlets pass through into
the foot wall rock.

Ore bodies Of this character are ex-

in batteries and on apron plates. Two
ive-foot Huntington mills are being
added which are expected to treble the
capacity. The fuel used is pinion pine
from the neighborhood. Water is
brought in by pipe line from Jefferson
Creek, a distance of four and one-half
miles.
1t IL probable that the oxidixed ores
of his belt will continue to a depth on
the dip of at least several hundred feet
below the present workings. Mining
and milling should be done at unusually
low cost, with a high percentage of saw
ing. Water for all probable milling
needs is available. Such timbers as are
required can be cut in the neighboring
hills. 1t is known that at least one
parallel vein underlies the Sunnyside
vein. 1t is not unlikely that there IL a
series of rather fiat east-west assures,
from the lowest Of which the more ver-
tical veinlets take their origin extending
to the surface. caused by the downward
slip Of so weak a hanging wall rock. 1t
is believed by Mr.. Davis. and I think
with reason. that eventually very large
mills will be operated on low grade rock
lying between the fiat veins. n en-
riched by the system of veinlets.
There are several properties of much
promise in the district. which I could
not examine because time was limited.
The Fairview has a fve-foot Hunting
ton mill and Is understood to be crush
ing a good grade of ore. The Sphinx.
the Fairview. the Daisy. the Antelope,
the Round Mountain Extension are un-
der active development within the rhyo-
lite belt. The Red Top adjoins the An
telope and is to be developed by strong
people. The Comstock shaft is being
sunk in alIuvial on the strike OF the
Sphinx vein.
/ am told by Mr.. Baxter, who has ex-
mine the district carefully, that
geological conditions in these properties
are similar to those observed In the
Sunnyside. Aside from questions OF
ores and values. which must be deter
mined in each property, success in this
district would seem to depend very
largely upon correct knowledge of the
veins and their peculiar Irregularities.
From a tract approximately 900 by
800 feet on the south slope of Round
Mountai and on the ~Sunnyside prop
erty. Thomas Wilson has taken $4,000
in placer gold. with dry washers In
thirty working days. Bedrock is from
q few inches to eight feet below the sur
face. Further out in the wash a shaft
about 10 feet deep has been sunk
through pay gravel without reaching
bed rock. These placers extend. with
some breaks, from below the Fairvfew
mine and nearly around Round Noun
tain.
The Round Mountain Hydraulic Min
ing has nearly completed a To-
inch pipe line from Jefferson Creek. IL
is estimated that 400 miners inches VIII
be delivered. The working head will be
425 feet. Monitors will be used and the
whole of these placer deposits hydraul-
licked by the company. 1t is expected
that over $500, 900 will be realized. This
enterprise was started by George Bart
lett. editor Of the Round Mountain Mug
get, with whom is associated Mr.. VIII
son. Messrs. LOTUS and Davis financed
the enterprise and are building the pipe
line. which should bceompleted by Sep
TENDER 1. After the placers shall have
been worked out. this great water sup
ply will be used for milling purposes.
