of a visit to Hynson's Springs, had not been visited by Dr. Penrose in his reconnaisance 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 measured 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 ot 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 forwarded 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 assistance during the course of the work.

Very respectfully,

WM. KENNEDY.
Assistant Geologist.
