New Publications.

During the period covered by this issue (September 15, 1923-January 15, 1924), the following Bureau publications have been made available for distribution:

Bulletin No. 93, "California Mineral Production for 1922," by Walter W. Bradley. For free

distribution.

Summary of Operations, California Oil Fields, Vol. 8, No. 12, June, 1923; Vol. 9, Nos. 1, 2, and 3, July, August, and September, 1923, respectively.

Mining in California, September, 1923, Vol. 19, No. 4.

Commercial Mineral Notes: Nos. 6 to 9 (inc.), September to December, respectively.

As the timeliness of publication is important in the case of the lists of 'mineral deposits wanted' and 'minerals for sale,' this information is issued in the form of a mimeographed sheet once a month since the change to a quarterly status of 'Mining in California. This list is mailed, free of charge, to those on the mailing list for the quarterly.

In connection with the monthly 'Commercial Mineral Notes,' it has been gratifying to receive the many congratulatory letters and statements telling of its value and the practical results obtained from it. We have been informed of actual business and of sales directly traceable to the data thus disseminated.

Mails and Files.

The Bureau maintains, in addition to its correspondence file, a mine report file which includes reports on some 7500 mines and mineral properties in California. Also there is available to the public a file of the permits granted to mining and oil corporations by the State Commissioner of Corporations.

During the period of July 1, 1923, to January 15, 1924, there were 3750 letters received and answered at the San Francisco office alone, covering almost every conceivable phase of prospecting, mining and developing mineral deposits, reduction problems, and marketing of refined products.
