LETTER OF TRANSMITTAL.

GEOLOGICAL SURVEY OF TEXAS,

Hon. J. E. Hollingsworth, Commissioner of Agriculture, Insurance, Statistics, and History, Austin, Texas:
DEAR SIR—I have the honor to transmit herewith the Third Annual Report of the Geological and Mineralogical Survey of Texas.
This report contains, as far as we have been able to prepare them, the results of the work of the Survey for the year 1891. Much material, however, still remains on hand for study, and until proper determinations on it are secured final conclusions cannot be drawn in regard to many points of interest and value. Some of the determinations depend on an increase of library facilities, and others on our opportunity and ability to secure the work of specialists in certain departments of scientific work—difficulties which can only be overcome gradually.
Please accept my hearty thanks for your kindness, consideration and assistance during the progress of the work.
Yours very truly,
E. T. DUMBLE,
State Geologist.
