will drop directly from the receiving
bin into the tube mill. After pass
ing over the plates, a Dorr classifier
will return the sands to The tube mill
for regrinding.
Excellent results are being OBJ
tanned by the present Mushett : Wit
tenburg ten-stamp mill in the treat
ment of the oxidized ores from the
upper levels of the property of the
Dexter White Caps Mining company.
Since Oct. 81, a total of 587 tons
has been treated. The zinc boxes
show an extraction of $5,105 with
about 100 tons in the mill in process
of reduction. An average extraction
of more than 80 per cent is being
made. An immense tonnage of OK
idized ores has been developed In
the property, it being estimated that
300 tons are at present available.
In addition to the extraction of the
oxidized ores, the company is Wig
orously pushing the development OF
the sulphide ore bodies on the low
err levels of the property. 1t is esti-
mated that 700 ions of $40 ore of
the sulphide variety have been placed
on the dumps, in addition to three
carloads shipped that yielded aver
age returns of $35 per ton. On the
second level of the property it is
calculated that $4,000 in ores has
beendeveloped since last Jan. increas-
ing the total estimated tonnage in
the entire property to 10000 tons of
the gross value of $4,000
The Nevada California Power COM
pany has practically completed the
installation of a power line from
Manhattan to the old camp of Bel
mont. 1t is understood that the Bel
mont company, which is to be sup
piled with power, has ordered a full
complement of machinery for deep
will be the unwatering of the 500
foot shaft on the property. The
water in the shaft now stands at the
2OO-foot level. The plans of the
company include the ERECTION of a
mill to treat the enormous tonnage
of silver ores available in the va
rious mines of the old district.
The production of pebbles at the
Maris ~chalcedony quarry for tube
mill work seems destined to develop
tntO ON rnnnrfont indrctrv ncnno-
tally since the foreign supply has
been curtailed in consequence of the
European war. All the mills of Man
haitian and many of those of Tono-
pah are now using the Maris peb-
bles. On certain kinds of ore, the
Maris pebbles have proved superior
to the Danish product. The owners
of the quarry are at present making
numerous improvements in their
equipment for the making of pebbles.
A new tube mill, to be used for
grinding and sizing the pebbles, IS
now being built at the Campbell and
Kelly foundry in Tonopah. This mill
will grind a charge of two tons of
pebbles at a time, it's dimensions
being six by four feet. with an inter-
ior cast lining. 1t will be operated
with a t~hirty-power gasoline engine
and it is calculated that ii will be
possible to turn out two tons of fin
ished pebbles in three sizes every
hour. The quarry owners have
placed an order for a %seven-ton auto

the pebbles to the mills of ronopah,
a distance of thirty-nine miles. The
West End Consolidated Mining CON-
pany has just completed a six weeks
test on the Maris pebbles in it's mill
at Tonopah. and is it said that it
found them practically as efficient
as those imported from Denmark.
