NEW LITTAUER SCHOOL GETS FACE SCRUBBED REGULARLY

Coolidge, Shepley, Bullfinch and Abbot, architects for the new Littauer School of Public Administration, besides having a remarkably metrical name, are careful workmen. For weeks as the great gray structure reared itself, members of the Philips Brooks House staff across the street wondered why battalions of men periodically scrubbed all its stone surface.

It's not just to provide jobs for a crew of scaffold-sitters, although the weekly washing will continue until the building's completion.

A construction foreman explained yesterday that mortar and dust must be kept off the stone and this is done by scrubbing with brushes, water, and diluted acid. "We've got to turn the building over in good shape," he said. "After that it can just age naturally."
