LETTER OF TRANSMITTAL.

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

DEAR SIR—I transmit for publication "A Preliminary Report on the Soils and Waters of the Upper Rio Grande and Pecos valleys," by Prof. H. H. Harrington. The work of collecting and the study of these soils and waters was carried on by Prof. Harrington without any personal remuneration whatever, the Survey paying only his actual expenses while in the field, and it is therefore eminently proper that the thanks of the Survey be thus publicly expressed for his kind assistance in the preparation of this Bulletin.

Yours, very truly,

E. T. DUMBLE,
State Geologist.

AUSTIN, TEXAS, February 15, 1890.
