Excerpt from California Mines and Minerals Compiled by chas. G. Yale, Statistician State Mining Bureau. HE mining interests oi_ the State of California are so diversified, and the industry is extended over so wide an area, that it is difficult to describe the conditions which exist without using many pages of printed matter. For this reason it has been considered proper, in this pamphlet, to give merely a record of results, which will show in plain figures what is being accomplished by the miners of the State. This record shows that some forty-four mineral substances are being exploited, the annual valuation of which is now and increasing at the rate of about yearly, as capital is invested and more mines are opened. The older mines, too, having been well developed and equipped, are increasing their annual output, and thus also proving their permanency and value with depth. The climatic conditions are favorable to mining operations throughout the State, and means of transportation have been so improved as to greatly lessen costs of supplies, etc. There are abundant opportunities for the safe and profitable investment of capital in the various branches of the industry, as numerous claims which have been located have never been properly developed or equipped, their owners lacking the necessary means.

In 1866 William P. Blake, professor of mineralogy, geology and mining at the College of California, parent to the University of California, Berkeley, prepared as a report to the State Board of Agriculture an "Annotated Catalog of the Principal Mineral Species Hitherto Recognized in California and the adjoining States and Territories. " Seventy-seven mineral species appeared on the list. It was the beginning of a series that became known as Minerals of California. This first catalog was followed in 1884 and 1886 by a list of 135 species compiled by H. G. Hanks, the first state mineralogist of California, and pub· lished in the fourth and sixth State Mining Bureau reports. Then beginning in 1914 with a volume prepared by A. S. Eakle, professor of mineralogy at the Uni versity of California, Berkeley, the Division of Mines and Geology published new editions in the series at approximately ten-year intervals.
