THREE BIG COMPANIES ARE
CONSOLIDATED.
OPERATE TEN "GIANTS"
Leland Mining Co. Has Incornorotod
and Much New Machinery viii
BE Installed.

The rumored consolidation of val
liable Grave creek hydraulic mines
is now an accomplished fact The
merger just perfected means that
josephine county will have in the
near future one of the largest, if not
the largest, hydraulic mines on the
coast.
The consolidation includes the
well known John c. Lewis, H. X. Mil
Ter and Birthstone mining properties.
The combined acreage exceeds 700
acres and practically all of it is heav-
lily mineralized; the land is nearly
all contiguous.
Some of the Oldest and most val
liable water rights in the Grave
creek district are included in the
purchases. Fully 25 miles of ditch
and many miles of steel pipe will
carry the waters of Grave, Wolf,
Birthstone, Rat and Tom East creeks
to the property. The water rights
are exceedingly valuable and bitches
cost a fortune.
The richness of the gravel is be-
yond question. The properties are
fully opened in a dozen places and
there are numerous test holes and
pits demonstrating values ranging
from 10 cents to SO per cubic yard
of gravel. Considerable platinum
is present.
Preparatory work will be started
in a few days. Several car loads Of
new pipe will arrive about January
I and it is proposed to have 10 or
more giants operating day and night
as quickly as possible. A complete
hydro-electric plant will be installed
in the near future, new siphons will
be installed and water ways en-
larged
The wasteful methods in vogue
among placer miners will be elimin-
ated. Patented grizzlies or concen-
trating devices owned by the stan
dard Reduction company will super
cede the inefficient sluice boxes IN
the races. These devices screen (a'-
tomatically) the gold-bearing graVeiS
down from coarse sand to conceh-
trates which contain practically all
the gold and platinum values carried
in the gravels. The gravel cohcen-
trates will be delivered to large IT,
duction plant, which will be lmihe
diately installed upon the proper"
by centrifugal pumps or aerial trans
where the coarse sands VIII ne re-
concentrated and treated by tne
Standard Reduction company Inc"

tro-cbemical amalgamation' Wnicn
