include the spring semester, which consists of speeches focusing on an issue of concern to the liberal arts; and Orchesis, an annual celebration of modern dance and the arts, which occurs at the end of the academic year. "Fresh-X" is an optional program for newly admitted students that occurs just before orientation in which students may choose between hiking, backpacking and other outdoor activities to make friends with their new classmates. The campus used to host two major musical events, Unity through Music and Springfest. Unity through Music occurred once a year in the fall semester, and covered various musical styles in a carnival atmosphere, during the day; while, during the evening, a huge dance is held in the Hamilton-Williams Campus Center. Springfest, the second musical event, proceeded in mid-April and had featured well-known music groups such as Counting Crows, The Roots, Guster, Ben Folds, and Gym Class Heroes. It was organized by the Campus Programming Board, who have changed the name to "Bishop Bash," in an attempt to create more campus pride. Bishop Bash has hosted multiple different styled events, including Drake Bell, Bo Burnham, and most recently, in 2017, The Mowgli's and NeverShoutNever. A rock next to Hayes Hall has been part of the residential campus for the last 50 years, and students continually repaint it with graffiti and slogans. Housing The university can house up to 1,600 students on campus. First-year students are required to live on campus in Smith Hall during their first two semesters. A lottery system matches second to fourth-year students with dormitories and another lottery system determines how many students are allowed to live in off-campus housing. Housing options include dormitories, small living units, fraternities, and cooperative housing. Thomson, Bashford, Stuyvesant, and Smith Halls are large mid-rise dormitories on campus. Welch Hall is designated as a "quiet" dorm for honors students. Hayes Hall is an all-female dorm. Approximately 90 non-freshmen students live in Small Living Units (SLUs), which are co-ops united voluntarily to meet shared economic, social, and cultural needs and aspirations in democratically controlled houses. The houses allow students to live cooperatively with one another by sharing regularly scheduled house chores, participating in the decision process, and, in some, sharing the cooking duties. Each unit houses a group of 10–17 students, and is organized to promote a common theme, usually indicated by the co-op's name. As of the 2022–2023 academic year, the
