The gentleman's steward and tenants of manors instructed [electronic resource] : Containing rational, easy, and familiar rules and tables for finding the value of estates of freehold, copyhold, or leasehold, as well on lives as for years absolute, &c. With an enquiry into the nature of the annual disbursements, precariousness of the tenure, and casualties, that estates in fields or houses, or both, are charged with, or liable to; and how they are to be accounted for in the valuation. Wherein the errors and absurdities of all the common methods of valuation, and the disadvantages thence accruing, sometimes to the landlord and sometimes to the tenant, are justly expos'd. The tables for valuing estares on lives being founded on Dr. Halley's hypothesis, and calculated by the method laid down by Mr. Abr. De Moivre, to 4, 5, 6, 7, and 8 per cent. To which is added, an appendix: containing the description and use of an instrument for discovering the number of feet contained in any timber-trees before they are cut down, by inspection only.
