The mineral resource survey of Texas, which is being made by the Works Progress Administration, has been in progress since January 1936. Up to September 21, 1936, the survey has been carried out in 27 counties located in 12 of the 20 Works Progress Administration Districts of the State of Texas. The location of these counties is indicated on the accompanying map (Ed. note: No longer available, April 1971).

At present, the survey is in progress in Anderson, Angelina, Bexar, Gillespie, Jones, Montague, Nolan, and Travis counties. Part of the information accumulated by the mineral resource survey has been mimeographed in circular form and is now available for distribution. Fifteen such circulars have been issued. These may be obtained upon request.
