The iron "worm" tool is similar to a large corkscrew. With a handle attached, it would have been used to insert or remove wadding from a long tube, perhaps even a ship's a cannon. This "worm" was found buried on Preble House property on Great Cranberry Island. Among his many enterprises, William Pitt Preble built and salvaged ships on the island.
