THE UNITED STATES GEOLOGICAL SURVEY 65 PRINCIPAL ACCOMPLISHMENTS SINCE 1911 The Survey has published since 1911, county and areal reports, eco- nomic reports covering sand and gravel, oil and gas, water investigations, and general geologic reports covering the Devonian series. PRESENT MAIN LINES OF WORK The present activities include detailed geologic studies of the clay resources, lead and zinc deposits, and a study of the correlation of the Cambro-Ordovician formations of the Ozark region. A detailed investi- gation of the insoluble residues remaining from the treatment of strata from this series, a study of the paleontology of the Mississippian, and extensive magnetic and electric resistivity investigations are now in progress. PREVIOUS SURVEY ORGANIZATIONS The older Geological Surveys were sporadic in nature and although some publications were issued, they are not listed by series. The first Geological Survey was organized on February 24, 1853, the second on March 24, 1870, and the present Missouri Bureau of Geology and Mines on May 13, 1889. MONTANA * The Montana State Bureau of Mines and Geology was organized in 1919 as the Bureau of Mines and Metallurgy. In 1929 the name was changed as indicated. The office is at Butte, Montana, to which all mail, telegrams, and express should be addressed. SCOPE OF ACTIVITIES The laws governing the functions of the Bureau specify that it is .... " To study the geological formations of the State with special reference to their economic mineral resources both metallic and non- metallic .... To prepare and publish bulletins and reports with neces- sary illustrations and maps which shall embrace .... the natural resources and geology .... of the state." The law also specifies that the Montana State Bureau is authorized to enter into cooperative agree- ment with the United States Geological Survey and with the United States Bureau of Mines. * Information furnished by Francis A. Thomson, Director, April, 192g.

66 THE STATE GEOLOGICAL SURVEYS AND ORGANIZATION The governing board of the Bureau is the State Board of Education, a non-salaried Board, which has charge of all the units of the University of Montana. The Bureau of Mines and Geology, as a branch of the School of Mines, is by law placed under the direction of this Board. The executive officer of the Bureau, whose title is Director, is Dr. Francis A. Thomson, who was appointed in 1928. Doctor Thomson is also Presi- dent of the Montana School of Mines. The Director gives from one-third to one-half of his time to Bureau work, but receives no additional com- pensation for this. From one to two persons are employed on the clerical staff, and from seven to eight persons, at present, on the technical staff. Topographic surveys are being made in cooperation with the United States Geological Survey. Stan members are appointed by the Director, and in part they are also members of the School of Mines faculty. Some of them are employed in full-time teaching during the academic year, but devote their summer months to survey work. In other cases the employment is part-time teaching and part-time research. Advanced college students are employed as assistants on surveys. For field work, on a general per diem basis, compensation of $10 per day and expenses is allowed for geologists, and from $2.50~ to $3.00 per day and expenses for field assistants. APPROPRIATIONS From 1923 to 1929 the Bureau had no specific appropriation, but for the biennium 1929-31 an appropriation of $6,000 a year was available, and for 1931-33, $20,000 a year is available. There is no income from royalties. It is anticipated that the approximate expenditure for 1932-33 will be fifteen per cent for. administrative work, sixty per cent. for geologic work, and twenty-five per cent for metallurgical research. PUBLICATIONS Five bulletins were published from 1919 to 1923. In 1929 a new series of mimeographed pamphlets designated as Memoirs was begun, and in 1932 a series of shorter publications knot as Miscellaneous Coniribu- tions. Of the publications thus far issued, seven have been geological in character; one has. dealt with ore sampling; one with mining laws; and one has been a mining directory.
