recently erected hosting works alone being
the only object not visible when last l Wis.,

view from the vicinity Of the mine. II not

the merit Of retaining those peculiar At
tributes with which mother Nature IN
dowed the landscape Of the great corrugat-
ed basin If Nevada. In altitude, the site
whereon stands the new hoisting works
ranks not far below the highest point Of
Prospect Mountain. it having been ascer-
tanned to be 8, 100 feet nearer the celestial
spheres than are the crested waves which
lave the Golden Gate. The elevation OF
the majority OF the mines located along
the eastern and western slopes OF Prospect
Mountain, is about the same as that OF the
former. Commencing on the northern de-
clivity Of the slope, we nave the Bald
Eagle, the Atlas, the Dunderberg or Ruby

Fourth of July, the Hamburg, and other
mines on the east, together with the Ban
ner, the I'll Dorado, and some others which
cannot now be remembered. occupying the
same or like height. On the west. All Of
these mines are in good condition, and
many of them have largely contributed to
Eureka's prosperity, but not in the degree
to which the Hoosac has, the Ruby proper
ty alone excepted. Although all Of the
mines named have, by their developments,
lone much to remove skeptical prejudices
in regard TO the richness OF old Prospect,
the credit OF finally determining beyond a
doubt the value and permanence OF that
great ridge as q mining center, will, with
out a doubt, yet devclve upon the Pros
pect Mountain tunnel enterprise, and the
men who sustain it. This is to-day n Of
the most important undertakings that has
ever been in augurated in the district, as
are also tho Eureka and Charter Compa-
MES tunnels, now beng driven ahead with
the utmost despatch. The
FEATURES
OF the Hoosac Mountain, which is o lateral
offshoot Of the parent ridge, differs some
what from those Of other sections of the
district. For instance, lime and shale
predominant on Ruby Hill and along the
trend of the great mineral zon bearing
southerly from it. while quartzite, porphy-
ry and syenite prevail in the former locali-
ty. Quartzite and shale-the former on
the west and the latter on the east -iuclose
the ore bodies of bota Ruby Hill and
Prospect Mountain, while porphyry AID
quartzite seemingly perform the same Of
flee in the Hoosac. To the superficial OBJ
server, Hoosac Mountain looks exterioral-
ly as though il were nothing more than q
huge mass OF cold, barren, vitrous appear
ing quartzite, and such it is to some Ok
tent. Great belts of it course north and
south through the hill, and rear their
shaggy, weather beaten forms far above the
mountains configuration, inst as though
Nature set them there as landmarks for
those seeking her metallic treasures.
There are two distinct formations on the
h~ill-quartzite on the east and syenite On
the west. These are the local formations.
and though the latter has not yet been
reached, it is not beyond the bounds Of
possibility to meet with it either as foot
wall or otherwise as developments progress
westward. Porphyry, however, may yet
form the foot-wall to the lode towards the
west. In the old workings it was found to
invariably surround or inclose the ore
bodies, and from present appearances it is
not improbable that it may perform a like
duty in the developments now under prog
ress.
THE HoosAc MAIN SHAFT
Is now down 200 feet it is substantially
timbercd and AZ straight ~ an arrow. From
the bottom Of this shaft q drift opens
southerly for . few feet, and then bears
west, fifteen degrees south. At the time of
my visit, it had attained a linear trend Of
300 feet, the header showing well in an ad-
mixture Of porphryy and highly miner
allied quartz, ferrugenous seams and
stains, and other matter usually found
outlying and following or coursing along
the ore bodies of this district. These in
dications point with almost uuerring GER
tainty to the near approach Of the header
to where ought to be encountered the fine
ledge cut at about so feet from the surface,
and something about 800 feet westward
Of the shaft, and consequently entirely
severed from the old workings. On ex-
aiming this ledge, / found it to be % feet
wide (22 feet solid ore). but its lateral cx-
pansion appeared to be still greater. The
ledge is strong, well formed, and dips
northeast, or whereabouts, at about
all angle Of between 20 and so degrees,
though, it is possible, q proper measure.
ment may show the inclination to be much
more than here given. The line Of con
tact OF the GRE in place, which ia clean,
rich and solid, is at both east and west
clearly outlined, porphyry and qnartzite
cncasing. No ore has yet been ex-
tracted. beyond what was taken out Of the
drift run through it III cutting, and it is
likely that neither wines nor lateral drifts
will be run for some time to come, the
bottom developments absorbing every con-
sideration at present.
From the foregoing it will be noted that
the prospects Of this old and still valuable
property are Of the most encouraging
character. The one thing now most
needed is to prove the downward trend Of
the lode already cut, and that this will, i'll
proper time. be as fully demonstrated as
that there is now again q great and bril-
liant future opening for the Hoosac, | am
certain. The ledge cut has a true polar
strike, = fact which adds to its value. All
the great and permanent ore veins Of this
continent trend towards some point OF both
the Arctic and Antarctic circles of the
globe. So with the rock cleavayes of til e
globe. and 40 with all the great valleys and
mountain ranges Of Nevada, their axial
lines bearing quite regularly north and
south.
The works covering the mine are strong
and compact, aud the machinery ample for
all present purposes. The boiler is an up
right, 81 by CT inches, with horizontal en-
CINE Of t~wenty-four horse power. capable
Of hosting from a depth Of seven hundred
feet or more. and to which is attached a
48-inch reel, carrying a steel wire cable OF
sufficient strength to hoist from amy depth
that might be attained. The mine and
works are in good condition, but this is
not to be wondered at when we consider that
the whole is under the supervision Of so
experienced o man as Edward Emery,
foreman of tho mine, whose early training
on the Comstock eminenIy fits him for the
position he now fills. In conclusion. and
as a winding up to this lengthy article. 1
can not avoid congratulating both the
manager and mis- company on the bright
ness Of the prospects before them.
