Composite account book, full of interesting matter for the economic historian, but poorly preserved. Spme pp. have disappeared altogether, and B, 25-28, have been badly mutilated. Two sides, A and B with signs of old pagination here and there; these have been newly paginated, provisionally in pencil - A, 120pp.; B, 55.

Really gives a general account of the finances of the estate, with particulars of all kinds of disbursements, of which this is probably the most interesting (p.32). - "1716.
