The 10th Annual Report of the California State Mineralogist is considered one of the most important publications issued by that office. The report contains a study by Fairbanks on the geology of the Mother Lode region with a large map. This is followed by a county by county detailed review of the known mineral deposits, mines and prospects. The report contains a description of the known meteorite occurrences in California, a report on quicksilver mining, a report on gold mining throughout the state, and a report on auriferous beach sands. The book contains a wealth of historic information on California's mining industry in 1890 and this is well supplemented by the rare maps.
