silver ores. When ores are not natur-
ally in the state of chloride, they are
chloridized in a furnace and the roast

tific Press.
When making application for pat
ent to placer ground care should be TAX
en- to determine the exact classification
of the land and the clearest evidence
possible should be presented.
Quicksilver is obtained on the Paci-
fic coast from four minerals-cinnabar
meta-cinnabarite, native quicksilver
and tiemannite (mercuric selenide) &.
This latter occurs in Piute county,
Utah
The development of a mine is explor-
alton. The stopping and working of a
mine after it is developed is exploita-
ton. A good maxim in mining is keep
ing exploration well in advance of ex-
ploitation.
A normal fault is one in which the
hanging wall has sunk relatively to the
foot wall, and reverse or thrust fault
is one in which the hanging wall side
has moved upward relatively to the
foot wall
The slow backward movement of alb
rupt rock faces, due to weathering, has
been called the recession of cliffs.
The states of the Mariposa beds of
the California gold belt are proven to
be cretaceous by the appearance of
casts of the fossil aucella.
Sedimentary strata to a depth of II, :
900 feet have been removed by erosion
in some portions of the Grand Canyon
region in southern Utah.
1t has been asserted that all pyrite
contains gold in some amount, but care
full tests have been made by some of the
most expert chemists of the United
States geological survey and pyrite fire.

In the early stage of development of
a quartz mine it is often impossible to
tell whether or not the ground is more
valuable for mineral or agricultural
purposes. A vein small and low grade
upon the surface may develop into
valuable mine in depth. Several such
instances are of record.
The zone of oxidation in the copper
mines of Butte, Mont ends abruptly,
usually, the oxides and carbonates Civ
ing place within few inches to ores
of the normal sulphide type. In the
Homestake mines of South Dakota, sui
phide ores are found on every level be-
low the 100, but oxidized ore is found
as low as the 400 level.
A deal has been contaminated whereby
a Spokane syndicate has purchased section
q, township 2S, range SO, upon which the
Crystal mine is situated, near old Fort
Spokane. The purchase does not include
the 40 acres owned by the Crystal Com
pany, but takes in all the mineral lands
surrounding the Crystal, 600 acres in all
This land has been already patented.
The Gray Eagle is the latest mine to be
added to the list of choice showings in
the Inland Empire. 1t is in compare
lively new and unknown district. 1T is
located on Hook creek, about six miles
from the Great Northern, and about 10
miles from Davenport. A Spokane COM
pany owns it. Captain j. W. Heisner is
interested in it. Yesterday he received
box of samples from b. n. Danskin,
who had been sent down to examine it,
The Cumberland mine, near Silver City,
Idaho, has been sold by o. G. Labaree to
the Virtue Consolidated Gold Mining Com
pany of Montreal. George SOnnemann
and j. f. Branscombe, the Spokane men
who owned the control of the mine, and
w. L. Mcdonald, who is Mr. Labaree's
representative here, are authority for the
statement that the price is 81 100000 cash.
News of the consummation of the deal
reached the city yesterday. This is the
second large deal made by Mr. Labaree
this year, he having previously sold the
Virtue and Collateral mines, in Baker
City district, to the same company for
1925, 900.
The greatest placer excitement ever
known will be within the borders of Idaho
county within year. In the northeast
ern part of the county there is a compar-
atively unknown placer field, yet of which
sufficient is known to prove beyond a
question of doubt that it is immensely
rich in golden sands.
The drilling contest at the Spokane In
dustrial Exposition puts up the following
prizes: For the double-handed contest,
$1,000 will be offered, $500 to go to the
winning team, $500 to the second best,
and 5000 to the third best. There must
be at least six entries for this event, as
we'll as for the single-handed contest Each
entering team must put up an entry fee
of 10 per cent of the purse, that is 800,
but the prizes are so liberal that even the
