A NEW FIELD HOUSE
The outstanding improvement for the year is the new field house at the East Orange Oval the city's oldest playground. The architecture of the building is of Spanish Mission type. It is made of hollow tile and stucco with Spanish tile roof and reinforced concrete floor. There is a clock donated by Wilbur S. Johnson which strikes the hour and half -hour on a 125-pound bell suspended in the little belfry, the gift of the East Orange Baseball Association. The cost of the
building was $12,750 exclusive of clock and bell. across both ends of the play room and a built-in seat along one side with hinged tops and locks. In this room is an upright piano donated by the Griffith Piano Company. There are rooms for women supervisors and the superintendent, with lavatories, toilets and lockers, and lavatories and toilets for girls and boys. In front of the building is an open paved court 10'x26', upon which have been placed two large heavy settees made and
donated by William F. O'Brien. A few feet from this is a concrete fish pond six feet in diameter into which overflows the water from the two drinking fountains.
