    ONE SUBCHASER FOLLOWS ANOTHER--As the submarine chaser PC485 slipped into the Harlem River today, the keel for another one, the PC563, was lowered into place at the Consolidated Shipbuilding Corp. yards. The Navy is building the sub-chasers at a cost of about $1,000,000 each to intensify its drive against enemy U-boats.
