LETTER OF TRANSMITTAL.
Department of Agriculture, Insurance, Statistics and History.
Geological Survey of Texas,
Austin, Texas, May 1, 1890.
Dear Sir—I have the honor to transmit herewith the First Annual Report of the Geological and Mineralogical Survey of Texas.
The field work on which the Report is based covers the period from the organization of the Survey to January 1 of the present year, and it was found necessary during the preparation of the Report to supplement that work by trips in various directions, in order that the facts presented might be as complete as we desired to make them.
The Report is not intended to cover all that was done in this period, but only those parts which seem well established, and the publication of which will be of benefit to the State at large, and also to the workers on the Survey, leaving fuller details for future reports.
I desire also to express my thanks for your kind consideration and the assistance you have so willingly given me at all times during the progress of the work.
Yours, very truly,
E. T. DUMBLE,
State Geologist.
