REPORT OF MR. J. H. HERNDON.

AUSTIN, TEXAS, November 7, 1890
.

Hon. E. T. Dumble, State Geologist:

DEAR SIR—In accordance with your instructions of June 8, for me to undertake the study of Smith County and make a report on its geology, with especial regard to its economic features, I took the field on June 22 and made a rapid reconnaissance of the county, which has an area of nine hundred and fifty-seven square miles, and necessarily took a long time in order to get a general idea of its geology. This was followed by a systematic study of the county in detail.

I made Tyler my headquarters, and rode over the whole county on horseback, and have succeeded in mapping out the iron ore beds, pottery clays, lignites, and other economic products. My aim has been to present the economic features of the county in such a shape that they may readily be grasped by all, in the hope that by leaving out the details of stratigraphy, which have been discussed at length by other geologists, that this brief report would meet the wishes of those most interested in developing the mineral resources of the county.

I desire to express my thanks to Mr. R. T. Hill for valuable hints and assistance.

In conclusion, my thanks as well as my gratitude are due you for the personal interest you took in me by visiting me and giving me a fair start in my work. The valuable instructions and methods of investigation which you imparted to me in those few days when you were with me, the perfect freedom and the many facilities afforded me in presenting this work, have rendered it a possibility.

Very respectfully,

J. H. HERNDON,
Chemist in Charge, Geological Survey of Texas.
