LETTER OF TRANSMITTAL, 



Department of Agriculture, Insurance, Statistics, and History, 



Geological Survey of Texas, 

 Austin, Texas, May 1, 1891. 



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

 Texas: 



Dear Sir — I have the honor to transmit herewith the Second An- 

 nual Keport of the Geological and Mineralogical Survey of Texas. 



This Report is mainly devoted to the description of the mineral re- 

 sources of the State, so far as determined by the work of the Survey 

 during the two years ending December 31, 1890. 



We have endeavored to make these statements in such manner as 

 that they will be valuable to every citizen, be he land owner, farmer, 

 mechanic, capitalist, or what not, and have used illustrations and maps 

 freely to make clear the conditions under which the various materials 

 occur. I greatly regret that at the last moment circumstances arose 

 which prevented the coloring of the maps of the Central Mineral Re- 

 gion and of Trans-Pecos Texas, to indicate the geology of the areas, as 

 had been arranged for, and hope that they may be so issued in the near 

 future. 



Owing to the necessarily great mass of matter, and the limited ap- 

 propriation for printing, it has been found necessary to omit several 

 reports which it was intended to include in this volume. I would sug- 

 gest, in order to get them out more speedily, that they be printed as a 

 Bulletin. 



In conclusion, I desire to express my most sincere thanks for the 

 perfect freedom of action you have granted me and the unfailing assist- 

 ance and advice you have so kindly given at all times. Only under 

 such conditions was the amount of work which has been accomplished 

 by the Survey during the brief period of its existence a possibility. 

 Yours, very truly, 



E. T. DUMBLE, 

 State Geologist.
