We visit the Nantucket Marine Lab and its director, Rob Garrison, to see efforts of augment the islande's scallop population. At the house, Bruce Killen tells us that the Historic District Commission has rejected as ""too fancy"" the proposed Victori... (more)an fence, approving instead a simple Quaker picket. Painters Gerry Ratnecht and George Loranger applied a plastic filler to nail holes, sand, and lay down a top-quality latex paint on an island used to oil. Inside, Bruce sees carpenter Joe Topham finish out a new window with traditional Victorian trim. We meet landscaper Michael Flanagan, who is dry-laying walls of Pennsylvania fieldstone, then plasterer Howie Nair shows us what's involved in repairing the broken plaster cornice mouldings in the front room. Finally, we catch up with energy-conservation specialist David Weitz as he conducts a blower-door test on the building, trying to seal it up to meet the high standards of the utility company.
