Canyon, in which 253 miles of canyons were mapped and 22 possible dam sites were examined during 1925.11
The Director's services with the United States Coal Commission, for the special investigation of the national coal resources, terminated September 22, 1923. In March, 1924, he was made a member of the Naval Oil Commission.
Another aspect of the Survey's history in the scientific field finds expression in the publication in 1924 of “The Evolution and Disintegration of Matter" as a "shorter contribution" of Dr. F. W. Clarke's half century of study in evolution and the spectroscope. 11
3. Activities and Organization 1. Administrative Branch. (1) Office of the Director.—The Director exercises general supervision over
the Geological Survey; spends part of his time in the field, exercising general oversight over field work, during which absence from Washington administrative directorship is performed by an Acting Director; is a member of the Naval Oil Commission; delivers addresses intended to create or maintain contact between the Survey's scientific and
engineering investigations and the public. (2) Office of Chief Clerk.-The Chief Clerk has direct charge of, and is
responsible for, the conduct of administrative work,

rivers; special investigations of conditions affecting stream flow
1673 gaging stations, supervised by 23 district offices as follows:
C., Municipal Bldg.
Building, Los Angeles, Cal.
Hawaii--Federal Building, Honolulu. (3) Division of Ground Water:
Investigates subsurface waters; their occurrence, quantity, quality and
head; their recovery through wells and springs; and their utilization for domestic, industrial, irrigation, and public supplies, and at
watering places for live stock and desert travelers. (4) Division of Quality of Water—Chemist makes analyses of samples of
water and studies of methods of water analyses. (5) Division of Power Resources-Hydraulic Engineer makes monthly reports
of production of electricity, and consumption of fuel by public utility power plants, based upon reports received from about 4,000 power plants; reports of the stock of coal on hand at such plants at different
dates; and a report on developed water power in the United States. (6) Division of Land Classification Investigations—Chief Hydraulic Engineer
-Examination of public lands for designation under the enlarged and stock-raising homestead laws, and the examination of streams and neighboring lands for the classification of public lands with respect to their value for water power or irrigation.
VI. Land Classification.
Makes reports chiefly to the Secretary of the Interior, General Land Office, Office of Indian Affairs, and Federal Power Commission. The results of its work are utilized mainly in preparation of orders for the withdrawal from entry, restoration to entry, classification, and designation of the public lands, of informative and advisory reports, and of recommendations for appropriate action concerning public lands made to the agencies above named.
Involves: (a) Withdrawal, classification, and restoration of public lands
according to their mineral character; (b) solution of geologic and economic problems arising in connection with mineral land leases; and (c) preparation of reports showing the mineral character of specific lands for the information and guidance of other government bureaus charged with administration of public laws. The Potash Land Leasing Act of 1917 12 and the General Mineral Lands Leasing Act of 1920,13 opening to disposition extensive mineral deposits,
did not obviate the necessity for classification.14 (3) Division of Hydrographic Classification-Hydraulic Engineer. (a) Power Section-Hydraulic Engineer.
