Seymour E. Harris, associate professor of Economics and head tutor of Dunster House will serve as Acting Housemaster during the second half-year, Clarence H. Haring, regular Housemaster, announced yesterday.

Professor Haring, who holds the Robert Woods Bliss Chair of Latin American History and Economics, is starting Monday on an extended trip through South America which will keep him away from Cambridge until June.

Latin American Visit

"I am taking this trip in order to keep up with what is happening in Latin America," Professor Haring announced yesterday. "I haven't been down for three years and I feel that unless I actually see the situation firsthand I lose touch with it."

Sailing on the seventh he will head first for Venezuela, and then travel to Colombia, Ecuador, Peru, Chile, Argentina, and Brazil, spending from ten days to two weeks in each country.

This is Professor Haring's seventh trip to South America since he first visited the continent in 1918. He has traveled around the Latin American nations approximately once every three years since then.
