A contract was made with Robert Knight and John Salter, carpenters, to build a gallery at the southwest of the meeting-house. "Sufficient for four seats, arched sufficient to strengthen the house with stairs and other necessaries."    For the labor the Selectmen agreed to pay them twent-one pounds "in such necessaries as they chould have occasion of," and if the work was ended, the balance was to be paid in fish or mackrel at the market price.
