REPORTS OF GEOLOGISTS. CV 



of a visit to Hynson's Springs, had not been visited by Dr. Penrose in his re- 

 connaisance of East Texas. Owing to better facilities in the form of roads 

 and other means of transportation from place to place, the work of surveying 

 and mapping the iron ores, clays, and lignites of Harrison County was carried 

 on with much greater celerity than was possible in Cass, and the work was 

 completed in a much shorter period of time. The work in Harrison County 

 was finished by the 10th of October. 



The character of the work performed in Harrison County was similar to 

 that done in Cass County. The iron ores were examined and mapped. All 

 the clay and lignite exposures were visited and examined and described, and 

 the general geological and topographical structure of the county worked in 

 detail as far as possible. Many natural as well as other sections were meas- 

 ured and recorded, and many elevations from railway profiles and barometric 

 readings were obtained As with Cass, some of these sections and elevations 

 appear in the report, while the others are held pending fuller investigations 

 and the correlation of the several deposits. 



No attempt has been made to correlate these deposits, or to assign them to 

 any position in the geologic scale. They have simply been considered as 

 forming parts o± Penrose's Timber Belt Beds. 



After the completion of the work in Harrison County, I spent a few days 

 in the vicinity of Jefferson, Marion County, examining the clay deposits and 

 greensand marls of that region. 



During the month of October a reconnaissance was made of Gregg County, 

 with the view of ascertaining the existence, probable extent, and quality of 

 the iron ore of that county, with the intention, if found necessary, of making 

 a complete survey of Gregg County some time during the next season. 



Field operations were finished in the beginning of November, and since 

 that time I have been engaged in the office, working out such portions of the 

 reports as could not be done while in the field. 



Numerous specimens of iron ores, ferruginous sandstones and clays, with 

 some greensand marls, were obtained during the course of the work and for- 

 warded to Austin from time to time. All necessary analyses of these have 

 been made, and some of the clays have been submitted to practical fire tests 

 with the view of determining their refractory qualities. Some of the other 

 clays have yet to be tested. 



In conclusion, allow me to thank you for your advice and personal assist- 

 ance during the course of the work. 



Very respectfully, 



WM. KENNEDY. 

 Assistant Geologist
