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.
