By H. Earl Pemberton

In 1866 William P. Blake, professor of mineralogy, geology and mining on the university of California, dad or mum to the collage of California, Berkeley, ready as a report back to the country Board of Agriculture an "Annotated Catalog of the relevant Mineral Species Hitherto well-known in California and the adjacent States and Territories. " Seventy-seven mineral species seemed at the record. It was once the start of a chain that grew to become referred to as Minerals of California. this primary catalog used to be in 1884 and 1886 via a listing of one hundred thirty five species compiled by way of H. G. Hanks, the 1st kingdom mineralogist of California, and pub· lished within the fourth and 6th nation Mining Bureau experiences. Then starting in 1914 with a quantity ready by means of A. S. Eakle, professor of mineralogy on the Uni­ versity of California, Berkeley, the department of Mines and Geology released new variations within the sequence at nearly ten-year periods. writer 12 months Mineral Species A.
