Book and Snake

The Society of Book and Snake (incorporated as the Stone Trust Corporation) is the fourth oldest secret society at Yale University and was the first society to induct women into its delegation. Book and Snake was founded at the Sheffield Scientific School in 1863 as a three-year society bearing the Greek letters Sigma Delta Chi. As other "Sheff" societies, it was once residential and maintained a separate residential "cloister" at 1 Hillhouse Ave, which was built in 1888 and deeded to Yale after the institution of the residential college system. Members who lived in the society residence, or "Cloister", become the Cloister Club. Today, the building is the Yale University Provost's Office. A plaque honoring the society can be found on the first floor of the building. The Book and Snake emblem is a book surrounded by the ouroboros.

Like other landed Yale societies, Book and Snake owns its own meeting hall, or "tomb" at the corner of Grove St. and High St. As is tradition with the meeting places of Yale secret societies, the building is windowless and available only to the current members and alumni.
