State Mineralogist Is to
Issue an Important
Bulletin.

State Mineralogist Aubury proposes Is
suing a bulletin of the structural mater
ials and industrial minerals of California.
In carrying out his plan of publishing
separate bulletins of the several and
varied mineral resources of the State Mr..
Aubury has recognized the Importance of
these industries-an Importance that has
been overshadowed in the past by the at
fractions to gold, copper and petroleum
resources ana products. The structural
materials and industrial minerals in 1900
amounted to 81 0S0 240 or 1215 per cent Of
the entire mineral output of the State,
approaching within about 100000 of the
copper production and only a quarter Of
million dollars below the value of the
petroleum.
In the statistical bulletins issued by the
State Mining Bureau the structural ma
terials and industrial minerals are so
placed in their order that their important
segregation from the staple Cor indepeu-
dent minerals is not apparent. But there
Is no other proper Cor scientific) method
of presenting such statistics; and thus the
relative value of these materials and min
erals forming essentials in structure and
manufacture, in comparison with gold,
mineral waters, salt, natural gas and pc
troleum, has never been presented in a
way to attract attention.
1t has been known in a general way
that California produces certain materials
and minerals; but even the persons inter-
ested in the building. trades and the
are iOI Iully aware OIL the
possibilities of California in these re-
sources. So Mr.. Aubury proposes to make
plain not only to them that are interested,
but to all that care to read, the splendid
showing this State can-and doeS-make
in the production of the following named
structural materials and industrial min
erals:
Clay, cement, sandstone, granite, lime,
limestone, macadam, rubble, paving
blocks serpentine, marble, quartz sand,
glass sand, slate, antimony, mineral
paint, manganese, chrome, borax, fulicIS'
earth, asbestos, gypsum, pyriteS, tourma-
line, quartz crystals, lithia, mica, soda,
magnesite. turquoise, asphaltum and BIZ
luminous rock.
The relative value and Importance Of
the three classes of mineral products OF
the State have never been so clearly set
forth as they will be by the several bull
letins in process Of preparation and publ
cation by the estate Mining Bureau The
mineral products of 1900 as presented by
the statistical bulletin, when segre-
gated from their neurological order
and placed in their commercial reia-
ton, show that of the States total
mineral product the staple minerals pro-
duced a value of $2S, ,542, ,705; Industrial min
erals, $1,506 1853; structural materials, 81
structural materials and industrial mill
erals-representing 1212 per cent of the
whole-are worthy the issuance of the
special bulletin proposed by Mr.. Aubury
That clearer idea of the Importance of
these industries may be now presented
tural and industrial products, their value
and the names of the counties producing
them has been carefully compiled. The
materials mentioned fncIude all that have
for two years been recorded by the sta
tistician of the State Mining Bureau; the
