Having reorganized the school's curriculum and established the preceptorial system, Wilson next attempted to curtail the influence of social elites at Princeton by abolishing the upper-class eating clubs. He proposed moving the students into colleges, also known as quadrangles, but Wilson's Quad Plan was met with fierce opposition from Princeton's alumni. In October 1907, due to the intensity of alumni opposition, the Board of Trustees instructed Wilson to withdraw the Quad Plan. Late in his tenure, Wilson had a confrontation with Andrew Fleming West, dean of the graduate school, and also West's ally ex-President Grover Cleveland, who was a trustee. Wilson wanted to integrate a proposed graduate school building into the campus core, while West preferred a more distant campus site. In 1909, Princeton's board accepted a gift made to the graduate school campaign subject to the graduate school being located off campus.
