The new hoist of the Center Star at
Rossland, B. c., will be nearly as large
as that of the War Eagle. 1t will BE-
arranged either for steam or electric
power.
1t is reported that the war depart

Idaho informing him that the state au-
thorities must take care of the Occur
dAlene situation, as it is desired to
withdraw the federal troops as soon as
possible.
1t is interesting to note, as illustrating
the relative proportions of value in
which the British mint is utilizing gold,
silver and bronze for coinage, that in
1898, the year of largest coinage on rec
ord at thesroya mint, gold coin struck
represented a value of $2S 9O2, $780, silver
a value of s6.561 $50, and bronze, used
for pence and halfpence, value of
S422,775
The Red Bluff mine near Pony is now
free of water and it's development by
the Montreal syndicate will be vigor-

steady pumping to overcome the great
obstacle, but it's accomplishment has
demonstrated that with modern equip
ment the camp is practically dry one

the sale of the Thornburg placer claims
near Granite in Grant county, Oregon.
The purchaser was the Thornburg

to be the substantial parties. The price
was 500. 500.

Electric power as much as the power
of new discovery, is quickening the
spirit of enterprise in Nevada. Twenty

in what is known as the Comstock

Der of mines in which it has for years
been impossible to work the low grade

be Incorporated to operate them. They
are known as the Argentine, Morning
Star and Rob Roy groups. The sum
paid for the Argentine is $4,000 and
$4,000 is paid for the Rob Roy.
The new company will develop the
properties as rapidly as possible. They
have all been producers of rich ore.

The Red Dog mill, in the Rand dis
| trict of Southern California. has a rec
ord of 1873 tons of ore crushed, with
| returns of $2S0000. The Black Hawk
mill has crushed. including it's Guide
back record, 1850 tons of ore, yielding
| $1T3,600 in gold. The Eureka mill has
turned out $162,OO0 and the records of
others are about in the same proper
! ton. The Yellow Aster mill, with it's
30 stamps, is crushing from $40 to $50
tons of ore day. yielding from $50, 900
to $4,000 a month in gold.
The drying of ores by calcining pre-
| vious to dry crushing often does more
harm than good, particularly where
| the ores contain much sulphde mineral,
as the partial oxidation of the sui
phides interferes with the perfect oper-
alton of the cyanide process. The ores
should either be dried by long-contin-
ued low heat or be thoroughly roasted,
| burning or volatilizing all of the sui
phur present. Complete roasting can
| not be accomplished by the continuous
kiln process, which REQUIRES the ore to
| be treated in large Jumps for the rea-
son that the heat is insufficient to thor
oughly oXidize the interior of these
Jumps of ore.
| In sinking a shaft on small vein in
granite. says the Mining and Scientific
| Press, the vein dipped out of the shaft;
but, it being desirable to continue the
| shaft vertically, this was done: as the
vein in its dip got several feet from the
| shaft the granite became extremely
| hard. A crosscut was run, showing the
| vein to be about five feet from the
shaft and approximately parallel with
| it, standing vertically. 1t was then de-

ting out to the vein. The result was
