To the Editor: At Princeton, the unregulated Eating Clubs for the two upper classes have "Bicker" for what we call Rush, and the clubs have venerable cultures and reputations -- jock clubs, geek clubs, clubs for folks who say they don't believe in clubs, etc. At Yale, the heavy, discriminatory selectivity is in the junior year for places in the Senior Societies which polkadot the campus with their Tombs.
