The practical surveyor, or The art of Land-Measuring made easy : Shewing by plain and familiar rules, how to survey any piece of land whatsoever, by the plain-table, theodolite, or circumserentor: or, by the chain only. And how to protract, castup, reduce and divide the same. Likewise, an easy method of protracting observations made with the meridian; and how to cast up the content of any plot of land, by reducing any multangular figure to one triangle. To which is added, an appendix. Shewing how to draw buildings, &c. in perspective: of levelling; and also how to measure standing timber. By Samuel Wyld.
