Bleaching clay investigations in Gonzales County were made for the following reasons:
1. To collect data on the types of deposits and mode of deposition.
2. To direct attention to any new sites discovered.
3. To eliminate seemingly valueless areas.

Aid in this work was given by many individuals. Thanks are due to E. H. Sellards, Director of the Bureau of Economic Geology, F. B. Plummer, H. B. Stenzel, Glen L. Evans, and Robert Redfield, geologists of the Bureau of Economic Geology, and W. N. McAnulty, State Supervisor of the Statewide Mineralogic Survey. Particular thanks are due to Mr. Thompson, County Agent of Gonzales County, Mr. Windrow, AAA Administrator, and Mr. Fred Jahn, Surveyor of the AAA office. Most of the included maps were made from aerial photographs furnished by the AAA office. Investigation of the Reed ranch site was made by John B. Means, Jr., Assistant Project Supervisor, who was in charge of the Gonzales County project after the writer was transferred to Llano County.
