LETTER OF TRANSMITTAL, 



Department of Agriculture, Insurance, Statistics, and History. 



Geological Survey of Texas, 



Austin, Texas, May 1, 1890. 



Hon. L. L. Foster, Commissioner of Agriculture, Insurance, Statistics, and History: 



Dear Sir — I have the honor to transmit herewith the First Annual 

 Report of the Geological and Mineral ogical 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 supple- 

 ment 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 xhe work- 

 ers 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.
