California mines and minerals . es of the lode in the United States Reports on Mineral Re-sources, in the various reports of the State Mineralogist, and in thefiles of the Mining and Scientific Press.

A correct map of the underground workings,with a detailed history of the values of the ores, and the moreimportant experiences in mining, would be of great value in thefuture. Many expensive mistakes will doubtless be made owing tolack of information which might be furnished by a suitable system ofrecord. It is believed that a good purpose would be served if the Stateshould compel the filing of such information where it would be opento public mspection.
