Excerpt from Chapter of Report XXII of the State Mineralogist: Covering Mining in California and the Activities of the State Mining Bureau As one means of offering tangible service to the mining public, the State Mineralogist for many years has issued an annual or a biennial report reviewing in detail the mines and mineral deposits of the various counties. The weak point in work oiz this character has been that the results of field investigations were so long in preparation that they had lost much of their usefulness by the time they finally appeared in print. As a progressive step in advancing the interests of the mineral industry, publication of the Annual Report of the State Mineralogist in the form of monthly chapters was begun in January, 1922, and continued until March, 1923. Owing to a lack of funds for printing, quarterly publication was begun in September, 1923. For the same reason, beginning with the January, 1924, issue, it has been necessary to charge a subscription price of $1 per calendar year, payable in advance; single copies, 25 cents apiece. 'mining in Cali fornia' will continue to be sent without charge to our exchange list, including schools and public libraries, as are also other publications of the State Mining Bureau. Pages are numbered consecutively throughout the year and an index to the complete reports is included annually in the closing number.
