Panhellenic in 1923-1924 consisted of Pi Beta Phi, Chi Omega, Phi Mu, and a local sorority, Zeta Eta Phi. The Consitution regulates the struction of Panhel and also the rules for rushing. During the first week of school, all women participate in a "Little Sister" plan sponsored by the Y.W.C.A. All women in sororities must not reveal their membership during this week.Â After this week and prior to rushing, no new girls and present sorority members may associate socially or discuss Greek life. Bids were sent out the first Thursday after Thanksgiving.
