lxXXVili REPORT OF THE STATE GEOLOGIST. 



broken, and cut by intrusive porphyries, basalts, granites, and other 

 eruptives. 



These conditions of structure prevent any other than a general un- 

 favorable report on the district, although in certain localities conditions 

 may, and probably do, exist favorable to the securing of artesian water. 



ACKNOWLEDGMENTS. 



It gives me great pleasure to be able to publicly acknowledge the 

 kind assistance rendered the Survey by the press of the State in the 

 notices printed of our First Annual Report and the publication of many 

 extracts from it, as well as the special articles furnished them by this 

 office, whereby many items of interest and value have been disseminated 

 among the people more thoroughly than could have been done by means 

 of the regular report. 



The assistance rendered the geologists and their parties during their 

 field work by the citizens of the various sections visited has been of 

 greatest service, not only by the actual aid given, which was very great, 

 but still more by the fact thereby evinced of their interest in and ap- 

 preciation of our work. 



Tte co-operation of the United States Geological Survey, the United 

 States Coast and Geodetic Survey, and of Professors Heilprin, Hyatt, 

 Cope, and Dr. Roemer have already been mentioned, and our thanks 

 are due for it. 



To those who have worked with me on the Survej^ and have given, 

 each in his own field, their best efforts ; who have cheerfully carried 

 out the general plans of work as outlined by me ; who with conscien- 

 tious and continued labor, sometimes through hardships, and even at 

 the sacrifice of personal advantages, have by their work brought out 

 the great scientific and economic facts concerning the resources of Texas 

 which appear in part in these reports, and which will mark an important 

 era in the material advancement of the State; who have at all times 

 shown me all courtesy — to all of these I express my deep appreciation 

 of their kindness and return my most sincere thanks.
