FIELD WORK BY THE DIRECTOR.

The Director did not make the usual inspection visits to field parties in the summer of 1910 for the reason that he attended the International Geological Congress held in Stockholm, Sweden, which afforded opportunity for conference with the administrative officers of the official geological surveys of other countries. The Director also visited the French Army Geographic Service, which makes the official topographic surveys, and the office of the Geological Survey of Great Britain. The delegation representing the United States Geological Survey at the Stockholm congress included also Messrs. Emmons, Hague, Becker, Lindgren, and Cross.

In November the Director visited the California oil fields with a view of ascertaining present conditions and made a report on the results to the Secretary of the Interior, urging remedial legislation. In May and June, 1911, in company with a geologist and an engineer, he made a preliminary examination of the two forest tracts in Georgia and Tennessee, on which favorable reports were afterwards submitted to the Secretary of Agriculture for the use of the National Forest Reservation Commission.

GEOLOGIC BRANCH.

ADMINISTRATION.

The geologic branch embraces four divisions-(1) geology, C. W. Hayes in charge; (2) Alaskan mineral resources, A. H. Brooks in charge; (3) mineral resources, E. W. Parker in charge; and (4) chemical and physical research, G. F. Becker in charge.

The chief geologist, C. W. Hayes, has general supervision of the work of the geologic branch, and the divisions composing the branch cooperate effectively in the several lines of work which are being carried on. Members of one division are employed in the work of another whenever it seems desirable, and such transfer is easily effected. The statistical reports of the division of mineral resources are for the most part prepared by geologists, who are detailed to the work from the division of geology for a portion of the year.

PUBLICATIONS.

The publications of the year prepared in the geologic branch included 5 geologic folios, 1 professional paper, 19 bulletins, and the annual volumes on mineral resources. Besides these publications a considerable number of papers were, with the permission of the Director, published in scientific journals and in the transactions of scientific societies. Such publications are ordinarily restatements
