The Arctic explorer has been credited with pranks such as releasing a small pig on the speaker's platform at convocation, and rolling a keg of beer across the campus to win a bet when North Dakota was a very dry State. There was then no trolley from Grand Forks to the campus, and President Merrifield was driven the two miles to and from town in his private carriage. One day Stefansson saw the carriage parked downtown. The driver was old in service, and when Stefansson stepped into the carriage and said "Home, Peter" in a good imitation of the president's voice, Peter suspected nothing. Stefansson rode in comfort to the campus, while President Merrifield, it is said, walked. Expelled in 1902, Stefansson was called back to his Alma Mater in 1930 to have the LL. D. degree conferred on him in recognition of his contributions to science. The east campus road passes the LAW BUILDING, WOODWORTH HALL, CHEMISTRY BUILDING, and BABCOCK HALL. In Woodworth, the school of education, is the campus broadcasting studio. The University of North Dakota was the second university in the United States to offer courses in radio administration, and engineering students use the KFJM transmitter, adjacent to the campus, for practical class work in technical radio instruction. Just S. of the Chemistry Building are the university tennis courts, and a nine-hole golf course is E. of MEMORIAL STADIUM (L) erected in 1927. The university athletic department is a member of the North Central Conference and books games with schools from coast to coast. The UNIVERSITY MUSEUM on the top floor of Babcock Hall (_open 9-5 daily_) contains a large collection of Indian artifacts and geological and historical items. The road curves back of Babcock and the COMMONS past CAMP DEPRESSION (L), established in 1933, where railroad cabooses are fitted up for enterprising students to provide cooperative accommodations at a minimum cost. Left of Camp Depression is the shiny arched steel WINTER SPORTS BUILDING. Around the curve is the ARMORY (L) where athletic and social events and weekly convocations are held. The road to the R. passes BUDGE HALL (R), men's dormitory, built in 1889; OLD MERRIFIELD HALL (L), generally known as "Old Main," the first building on the campus and now occupied by administrative offices, post office, book store, and offices of the extension division; NEW MERRIFIELD HALL (L), the liberal arts college building, completed in 1929; SCIENCE HALL (R), housing the medical school and State Public Health Laboratories; and the LIBRARY (L), containing 77,000 catalogued books and periodicals and about 17,500 uncatalogued Government documents.
