The practical surveyor, or, the art of land-measuring, made easy. Shewing by plain and practical Rules, how to Survey any Piece of Land whatsoever, by the Plain - Table, Theodolite, or Circumferentor: Or, by the Chain only. And how to Protract, Cast up, Reduce, and Divide the same. Likewise, A New 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: Being more exact and expeditious than heretofore used. To which is added, an appendix, Shewing how to Draw Buildings, &c. in Perspective, from Observations made by the New Theodolite, its Use in Levelling, in finding the exact Number of solid Feet, contained in any Timber Trees before they are cut down, by Inspection only; and also the Use of a new-invented Spirit-Level. With several other Things never before made Publick. By Samuel Wyld, Gent.
