yield was 230 tons, but the industry Is not
profitable. Corundum Is used as an
abrasive for grinding, polishing, etc, as
is garnet and emery, but its use is now
greatly lessened by the superior though
more expensive artificial product called
carborundum. Corundum sells for from
to 10 cents per pound, according TO form

with a novel way of inspecting bedrock

Dredge buckets cannot dig gold out OF
creVices and little holes, and in dredging
it is well to know about the gold left on

an experienced mining man OF intelll-

State and in Mexico, and who before the
outbreak of the war was for two years
superintendent of the Gold Coin mine at
Randsburg. Patriotism led him to enlist
as q volunteer. and he is a non-commis-

ties of the Philippines to the small eX-

nothing about mining except that in the

The. military situation is such that it
is impossible to verify all these reports,
and the Spaniard is so consistent and per-
sistent liar that you naturally conclude
that he avoids the truth on all occasions
There is much Ignite coal of a very good
quality scattered all through the group,
with some veins partly developed at Can
tanduanes by the Gil brothers, who sell
it to trading steamers at about $13 Mex

Mines here promise to be very wet as the
rainfall is great and the country a huge
sponge. Some attempts al coal digging
had to be abandoned by Spaniards, who
use no pumps, on some coal prospects
near Albay dipping 30 degrees into the
hill.
Miners would better stay out of this
country for at least year after the ma
tives surrender, for bands of so-called
Tuizanes will be the result of the break
ing up of the Filipino armies. They are
bands of robbers that Spain was never
able to suppress. They rob and kill i'm
partially. and their capture in the hills
and jungles is rather uncertain. The peo-
pie of these islands will never be ef-

spades After all said and done, the talk

be bitter day for the United States"
The Los Angeles llmeS says that there
is more prospecting being done on the
desert now than during any year since the
discovery of the Randsburg mines. From
Mojave on the west to the Colorado River
on the east, and all the way south of the
Tehachapi range of mountains. all the
camps are busy. The Ballarat region has
never looked so promising as now; the
Rademacher district is substantiating its
first claims to the possession of rich ore
bodies; In the Rand district there is not
a stamp idle. and other districts are live
ly with prospecting, developing and pro-
ducing.
The Golden Key Mining Company, op-
Grating in Tuolumne County, has elected
the following officers: C. Nauman, presi-

treasurer.
Quite a number of mining properties
have been bonded in Tuolumne County
within the past week or two by people

are close to noted properties. This sort
of work going on so steadily all through
the mining regions means the addition { (
many new mines to the list of producers
