rounding the Giant claim. Montgomery
himself staked a dozen or fifteen after
he got his first assays from the Giant.
The Rock Formation.
OF the rock formation of the camp III
is not possible to speak with certainty
yet, except in the most general way, ior
the hills are covered with "wash" that
co~nceals the rock, just as they are az
Cripple Creek, only at Cripple Greek the
soil was sodded aud here it is bare or
covered with sagebrush.
This much can be said. however, with
condolences: The hills are to u large ex-
tent made up of the sedimentary rocks
The quartzite and the crystalline lime
outcrop prominently in many places
and both are stained to the same color
by iron manganese. These strata APP
pear to be cut by dykes of rhyolite and
are olivine.hornblende rock, which is
probably a Enthusiastically not a
basalt.
At the Giant property there is a sus-
picion-not to state 1t more strongly
of a phonolyte dyke. 1t is claimed that
the ore of the Giant is q telluride, but
it is in very minute specks and the
larger crystalline forms of tellurium to
which my eye is accustomed are not
present. l cannot venture a positive
assertion that the rock is phonolyte. but
phonolyte is largely the carrier of tellu-
ride ores of Cripple Greek aud this per-
haps led me to suspect too confidently
that the rock in the Giant is a phono-
lyte dyke. However, it has been 50
finely brecciated and metamorphosed
and cemented together by a network OF
v~einlets of jaspery quartz that its orig
inal character is masked beyond posi-.
tive determination.
There has been extensive volcanic ac-
ton surrounding the locality and the
evidences of subsequent hot water out
flow over the region are indubitable.

though there are several camps of pros
| pectors in the region and all claim to be
getting good pau and fire assays. very
little regular and convincing develop
ment work has yet been done on rock
in place. Even on the Giant property
the depth does not yet exceed 20 feet
and is not in the way Of a regular shaft,
but rather in W pits. In n of these
only have they gone below the oxy-
died surface rock.
Awaiting Returns of Shipment.
That some of the ore in the Giant is
very rich in gold is certain. Assays
have shown 5000 in value. but how
the whole output is going to average is
the serious question. The shipment
just made Will determine that pretty
fairly, for l saw it on the platform here
before it was shipped and saw the ore
piled up at the mine, N think the
shipment may safely be accepted as rep
resenting the run OF the ore.

regarded as a mine. but only as a ship
ping prospect Of ~stupendous promise.
1t is not possible to say how much Of
an ore body there is, but there are indi-
cations that it will prove very large.
There is no cl~early-defined vein in sight
and one would be inclined to guess that
the property has been the seat Of extern
sive hot-water action that has mineral
lied a large area and filed the broken
rock with veinlets of quartz.
AS ! said, the fate of the camp and Of
all hopes based upon it hang upon the
returns from this shipment. II it runs
up to 500 it will prove the discovery a
great one that must inaugurate a great

Eureka and Lander, which have always,
till the recent desert discoveries, ranked
second and third. respective. in Ne.
