Excerpt from California Journal of Mines and Geology, Vol. 33: Quarterly Chapter of State Mineralogist's Report XXXIII; January, 1937 Though many unpublished reports and maps were examined and used, only a portion of these (such as university graduate theses) 1s actually listed. The others represent confidential reports of private individuals or of geological departments of oil companies and other commercial concerns. The numerous contributors have been exceedingly generous. If some have been omitted from this list it is either because of the desire of the contributor or an oversight on the part of the writer. It is the writer's desire, however, that this list of sources be made as complete as possible. Needless to say, the state geologic map would not have attained its present approach to completion if unpublished maps had not been so generously given to the undertaking.

Excerpt from California Journal of Mines and Geology, Vol. 31: Quarterly Chapter of State Mineralogist's Report XXXI; January, 1935 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. As a progressive step in advancing the interests of the mineral industry, and 'as permitting earlier distribution to the public, publica tion 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 this was changed to a quarterly publication, beginning in September, 1923. For the same reason, beginning with the January, 1924, issue, it became necessary to charge a subscription price. This covers approximately the cost of printing. Pages are numbered consecutively throughout the year and an index to the complete report is included annually in the closing number. Beginning with the 1930 issues, the activities and progress of the Geologic Branch are recorded also in these quarterly chapters. The important part that geology plays in the economic development of our mineral resources is further recognized in the change of title from Mining in California to california journal OF mines and geology, beginning with the January, 1933, chapter. While current activities Of all descriptions are covered in these chapters, the practice of issuing from time to time technical reports on special subjects will be continued as well. A list of such reports now available is appended hereto, and the names of new bulletins will be added in the future as they are completed. The chapters are subject to revision, correction and improvement. Constructive suggestions from the mining public will be gladly received, and are invited. The one aim of the Division of Mines is to increase its usefulness and to stimulate the intelligent development Of the wonderful, latent resources of the State of California.

In some places the veins cut through both of the formations mentioned. This production was made in 1913 and earlier, with hand tools, and the treatment was in arrastras. Widths varied from a few inches to a maximum 'of 8 an average of about 2 ft. These workings have Since caved. Only assessment work was done for many years, but recently Carter has been working steadily in a lower tunnel.
