Notes

1. The oldest traditional fraternities (~junior societies) at Yale named their buildings with "Hall" nicknames, by which they wished to be known on campus: Thus Psi Upsilon became the Fence Club. Similarly, Phi Gamma Delta was Vernon Hall which later became Myth and Sword. Sigma Delta Chi (local) was renamed the Cloister Club which soon became Book and Snake. Theta Xi's chapter was Franklin Hall, Phi Sigma Kappa adopted the name Sachem Hall, and Delta Psi adopted the name St. Anthony Hall which spread to their entire small national fraternity. Chi Delta Theta (local literary honorary) established the Manuscript Society, Chi Phi was York Hall, and finally, Delta Phi was known at Yale as St. Elmo's.
