Debating teams representing Harvard, Yale, and Princeton will compete in their fifth annual triangular debate tomorrow evening at 8 o'clock. Harvard will meet Yale in Sanders Theatre. Princeton will meet Harvard at Princeton, and Yale will meet Princeton at New Haven, the home team in each case supporting the negative. The question for discussion this year is, "Resolved. That the United States Government should Exempt our Coastwise Trade from Panama Canal Tolls."

Tickets are being sold this year, in place of the usual custom of soliciting subscriptions. The admission is 50 cents for main floor seats and 25 cents in the balcony and gallery. Tickets may be obtained at the Memorial Hall news stand or at the Co-operative branch store today.
