the popular backlash to Freemasonry has generally been rejected (a mysterious fire in 1841 destroyed the records of the first meeting of the Social Fraternity, erasing much of the organization's early history). Growth of the Social Fraternity (whose members were informally called the "Oudens") was exponential. By 1838 two-thirds of all students at Williams belonged to the society which engaged in militant agitation against the other two fraternities. One particularly violent incident occurred in 1839 when Oudens assaulted the Kappa Alpha house, driving its occupants to the top of Consumption Hill. More refined conflict took the form of pamphlets and debate. An 1855 debate proposed by Kappa Alpha against the Oudens was called-off after the Social Fraternity appointed James Garfield, an Ouden well known for his rhetorical skills, to represent them. In November 1847 Williams' Social Fraternity met with similar societies that had recently been formed at Union College, Hamilton College, and Amherst College and formed the "Anti-Secret Confederation". A second meeting of the Anti-Secret Confederation (A.S.C.) in 1852 saw fraternities from Wesleyan University, Case Western Reserve University, Colby College, and the University of Vermont join. At the 1862 convention, the fraternity's mother chapter, Williams, declared the purposes of the fraternity had been corrupted and, over the objections of the other chapters, withdrew. Two years later it dissolved itself. A chapter would eventually be restored. However, Williams being the first chapter and, therefore, self-chartering, this would come in the form of a new chapter and not the revival of the original. It was permanently erased when Williams College banned all fraternities in 1962. The March 1864 convention of the A.S.C. saw the organization formally change its name to Delta Upsilon, standardize insignia and ritual throughout all its member chapters, and establish a centralized administrative structure. Abandoning "anti-secrecy" In 1879, Delta Upsilon formally disavowed its policy of anti-secrecy, instead adopting a program of what it described as "non-secrecy". According to Delta Upsilon, the reason for this change was because it had been absolutely victorious in its battle against secrecy, "the character of the secret societies so altered, that hostility toward them decreased". This explanation has been more skeptically received by some, with one period observer caustically noting that Delta Upsilon "reveals very little more of what it does than the latter [secret fraternities]". Others commented that chapter meetings were closed to all but initiated members and the fraternity was now practicing
