JMA archeologists continued test excavations and expanded by 30 feet the trench containing the nineteenth century foundation remains. Earlier deposits, preliminarily dating to the eighteenth century, were found beneath the floor of the nineteenth century remains. Expansion of the trench led to the discovery of three additional foundation walls likely dating to the nineteenth century, and an additional wall of an earlier date. Also found were large remnants of wood, some with embedded wrought nails. Excavations continue tomorrow to determine if the wood remains are a trash or demolition deposit, or a decayed part of a structure.
