In 1739 the large square bounded by Fore, Middle, and Exchange Streets and extending about twelve rods west of Exchange Street, containing four acres, with a dwelling house and barn upon it, was sold by Benjamin Ingersoll to Phineas Jones for four hundred and fifty pounds. It is now one of the most valuable spots in town. The house was built by Benj. Ingersoll who kept tavern in it in 1728, probably the first public house in town after the resettlement. It was for many years the best house on the "Neck."
