LETTER OF TRANSMITTAL.

DEPARTMENT OF AGRICULTURE, INSURANCE, STATISTICS, AND HISTORY,
GEOLOGICAL SURVEY OF TEXAS,
AUSTIN, TEXAS, May 1, 1891
.

Hon. L. L. Foster, Commissioner of Agriculture, Insurance, Statistics, and History, Austin, Texas:

DEAR SIR—I have the honor to transmit herewith the Second Annual Report of the Geological and Mineralogical Survey of Texas.

This Report is mainly devoted to the description of the mineral resources of the State, so far as determined by the work of the Survey during the two years ending December 31, 1890.

We have endeavored to make these statements in such manner as that they will be valuable to every citizen, be he land owner, farmer, mechanic, capitalist, or what not, and have used illustrations and maps freely to make clear the conditions under which the various materials occur. I greatly regret that at the last moment circumstances arose which prevented the coloring of the maps of the Central Mineral Region and of Trans-Pecos Texas, to indicate the geology of the areas, as had been arranged for, and hope that they may be so issued in the near future.

Owing to the necessarily great mass of matter, and the limited appropriation for printing, it has been found necessary to omit several reports which it was intended to include in this volume. I would suggest, in order to get them out more speedily, that they be printed as a Bulletin.

In conclusion, I desire to express my most sincere thanks for the perfect freedom of action you have granted me and the unfailing assistance and advice you have so kindly given at all times. Only under such conditions was the amount of work which has been accomplished by the Survey during the brief period of its existence a possibility.

Yours, very truly,

E. T. DUMBLE,
State Geologist.
