THE UNITED STATES GEOLOGICAL SURVEY SOUTH DAKOTA ~ 101 The South Dakota Geological and Natural History Survey, organized in 1893, is still operating under the law that formed it. Only a few duties have been added. Its headquarters are located in the State Uni- versity at iTermillion, South Dakota. SCOPE OF ACTIVITIES The original bill calls for a. survey of everything in the State of eco- nomic or scientific importance either in the "mineral, animal, or vege- table kingdoms." The surveys of soils and agricultural plants and an- imals has been taken over by the State College of Agriculture at Brook- ings; and later rulings of the Legislature confine the work of the Survey primarily to economic geology. ORGANIZATION The Survey is governed by a Board of Regents of Education who are directly responsible for it as part of their duties. The Board is composed of five members who receive a small salary from the State for their ser- vices, but none from the Survey funds. The executive Dicer is the State Geologist, who holds that position by virtue of being Head of the Depart- ment of Geology in the the University. The position has been held by Dr. E. P. Rothrock since September 1, 1926. The salary has been paid by the University, except for two months during the summer when the State Geologist is paid from Survey funds at the same rate that he re- ceives for his teaching. Subordinates are hired as needed. A full-time clerk attends to details in the office. She is assisted by a stenographer and a draftsman, who are students in the University and give the Survey four half days a week. Geological field work hats been carried on during the summers by a number of the teaching staff of the University. In two instances grad- uate students have been hired for geological field work. For the past five years two or three undergraduate students from the Department of Geology of the University have been hired as drivers and assistants during the field season. No assistants for topographic work have been engaged. The help is employed by the State Geologist with the consent of the Board of Regents. Pay for the geologists ranges from $100 to $350 per month; for the clerical help, from $100 to $125 per month; and for student help, from 30 to 40 cents per hour. *Information furnished by E. P.
