The Geologic Branch has issued eight publications this last biennium. It has five manuscripts on hand, and ten practically completed field investigations (most of which are contributions). A new bibliography for the five-year period, 1931-1935, is nearly ready for the printer. A revision of Bulletin 91. "Minerals of California," is in the making. A struggle has been made to issue a preliminary outline of the state geologic map this year. The plan is to publish altogether four state maps (scale 1:500,000): (1) Topography and first preliminary geologic map; (2) mineral deposits and second preliminary geologic map; (3) oil and gas fields, fossil localities, and third preliminary geologic map; and (4) Final colored geologic map. Each will be issued in six sheets, 27 × 42 inches.
