CO-OPERATION OF THE UNITED STATES COAST AND GEODETIC
SURVEY.

Captain Stelman Forney, of the United States Coast and Geodetic Survey, had charge of the party at work in the Rio Grande, and he is now engaged in extending the line southward from El Paso toward Presidio.

WORK OF THE STATE SURVEY.

The United States Geological Survey having undertaken the topographic mapping of Trans-Pecos Texas, Professor Streeruwitz was enabled to use his party on some points of special interest in connection with the geology and mineral resources of the region. This included a survey of certain portions of the Carrizo, Diabolo and Quitman mountains, including the Hazel mine and accompanying vein deposits of copper ores.

Dr. Comstock's party, in making the trip from San Angelo southward to Eagle Pass, and from that point to Gillespie county, secured all of the topography possible along their route, connecting their line of levels and transit line with their work of the previous year, both on leaving and returning.

Professor Cummins' party also secured some details of topography along their line of sections around and over the Staked Plains.

GEOLOGY.

In May and June the parties took the field, under instructions which have been faithfully and efficiently carried out, and which have resulted in securing information of greatest value to the State. The work, as outlined in the instructions given, was intended to furnish material for a more specific subdivision of the various formations into terranes, and to assist in the correlation of the deposits as they occurred in different portions of the State, as well as the further determination of the economic possibilities of each terrane as a basis for the work of next year.
