Timber was an important resource to early Cape Ann settlers for building and heating houses. In 1642, a small committee was appointed to select a location for a sawmill and the Cape Pond Brook was chosen. A large dam was created and a water wheel was built that would power a saw to cut boards used in building homes. In the fall, the sawmill was used to grind corn. The mill was called Ellery Mill, as it was built by William Ellery.
