Brady Will Ref

Thomas Brady, head referee of the United States Polo Association, will referee the matches. He referees all matches at Meadowbrook, Long Island, all summer and is head of the referees' school at Squadron A in New York in the winter. Two years ago, he assisted in re-writing indoor polo rules.

The Harvard Polo Association, under whose auspices the intercollegiates have been brought to New England for the first time in history, yesterday announced that admission tickets for all games will be priced at $1.00, $.56, and $.25.

The new field at Westwood, which was given to Harvard this winter by W. Cameron Forbes, former Governor-General of the Philippines, is one of the best in the world and ranks second only to the international field on Long Island in this country.
