Bumpkin Island, also known as Round Island, Bomkin Island, Bumkin Island, or Ward's Island, is an island in the Hingham Bay area of the Boston Harbor. In 1900, Albert Burrage, a Boston philanthropist, had a hospital built on the island for children with physical disabilities. During WWI the island was used by the U.S. Navy. After the war the island was used as a facility for polio patients. However, the hospital burned down in 1945. Since 1996, it is part of the Boston Harbor Islands National Recreation Area. The island has an area of 30 acres (120,000 m²), plus an intertidal zone of a further 31 acres (130,000 m²). It is composed of a central drumlin with an elevation of 70 feet (21 m) above sea level, surrounded by a rock-strewn shoreline.
