BoRAx.
This mineral is largely produced in Cali
fornia; full description and history ma,
De found In the third annual report of thi
office. The total Yield of the State to Apri
80, 1884, was 231i2 2sG pounds a
the Worlds Fair in New Orlean:
last year the San Bernardino Bora,
Company of this State made a specia
exhibit of refined California borax, and
VIM L. Coleman showed some magnificent
| crystallized Nevada borax refined in Oak
and. A large pile of borax from each oil
these exhibits was placed on each side OF
the entrance to the California Headquarters
ana specimens given as souvenirs to visit
ers In this manner several hundred
pounds were distributed
MANGANEsE
Ores of manganese are abundant in the
State. They are used in glass making, in
chemical operations. for bleaching, and in
the extraction of gold from sulphureis, and
IN the Bessenler process of making soft
iron and steel. When wanted they will be
fpund III sufficient quantities to satisfy all
reasonable requirements.
TIM
Tin ores have been found at one locality
only, IN the Temescal tin mines. San Ber-
nardino county. As yet there has been no
yield, nor have the mines been extensively
worked or properly prospected There is
some reason to hope that this metal may
yet be found in paying quantities at the
locality mentioned
CEMENT.
Hydraulic cement has been found in the
state, and has been somewhat manufact-
ured. Some artificial cements and stones
have likewise been made, but the business
has never gained large proportions. The
splendid sidewalks that are now being ex-
tenslvely laId IN San Francisco are made
generally with imported cement. The
statement that pozzuolana had been found
in the State is entirely without foundation,
although among the numerous volcanic
rocks of the State that very valuable ce-
ment is likely to be found.
ANTHONY
Traces ofthis mineral, generally associated
with ores OF mercury, are found in numer-
Gus localities in the State. The metal has
been produced in small quantity. but
scarcely with profit to those who have en-
gagged in mining it. The outlook, how
ever, is good for more extensive produc-
ton.
ROCKS AND BUILDING STONES.
Building materials are very abundant in
California, and can be obtained in nearly
every part of the State Attention has
lately been drawn TO the importance of re-
placing the temporary wooden buildings
with those of more substantial nature
At Mokelumne Hill, in Calaveras coun-
", and at st. Helena Napa county,
,ufdceous volcanic or solfataric stone has
been utilized with great satisfaction, and
some beautiful as well as durable buildings
erected. This stone is so soft when first
quarried that il may be fashioned with
axes, and with time it hardens 1t is
likely to prove as useful and valuable as it
is extensive. Granite is somewhat also
used for foundations, and few buildings
OF that material have been erected. 1t Is
now well-known that beautiful marbles
abound in the State but they are not as
yet generally utilized. Brick of the very
best quality are cheaply produced, and
many fine buildings are being erected of
this excellent and most durable material.
1t is the intention of this Office TO make
special collection and study Of the rocks
and building stones of the State, and to
publish the results.
OTHER MINERALS.
The following is list of minerals of
lesser value which have been produced in
the State in considerable quantities, with
figures showing the estimated production
as far as known Salt. annual yield bay
salt, 10000 tons; sulphur, annual yield,
1,SSl,697 pounds; lime, annual yield, ,
15z, barrels. Gypsum and chrome iron
are largely produced, but no reliable figures
can be given.
The State is also rich in other economic
minerals which will evaufnallv ha ,vorl,ad
and which can be found when wanted.
The following are worthy of special notice:
Barite, bismuth ores, clays diamonds.
teldspar. kaolin, magnetism minerals. min
eral and alkaline waters, ochre. platinum.
quartz sands, zine ores. etc.
