Mettler's woods is an oak stand on the Piedmont of central New Jersey on the eastern edge of the town of East Millstone in Somerset County. The woods has been presumed to be, at least ill part, a fragment of -the forests that covered this section of the state before it was cleared by the white man. This presumption had its origin in a tradition in the succession of families that has owned the woods, that it has never been cut and cleared, and the presumption has been further supported by the soil profile, which is in amazing contrast with that of the surrounding fields.
