Defense housing, Erie, Pennsylvania. The old and the new. At the right is pictured one of the new defense homes now under construction, while in the background is shown one of the apartment homes built for the defense workers during World War I. Where as many of the latter homes were disposed of due to private concerns after the war, it is expected that many of the new defense homes now being built will eventually become part of the overall slum clearance program. Others will help fill the urgent peace time need in America for low cost homes
