To part off any portion of a Field in form of a Square. RULE. Reduce the given quantity to links, and extract the fquare root, which will be the length of a fide of the fquare required. It is required to part off 2A 3R 1P on the line AB, from C towards B in form of a Square. A 525 525 D B PART THE SIXTH. TO SURVEY SEVERAL FIELDS TOGETHER WITH THE CHAIN. THE foregoing methods of furveying are best adapted for fingle fields; but if feveral fields or a lordship is to be furveyed, the field-book must be kept in a different manner. To render this method as easy to be understood as poffible, I fhall give examples of fingle fields firft, and then of feveral together. The pages of the field-book must be ruled into three columns it is beft to begin taking notes at : the bottom of the laft page and write upwards. To furvey the Triangular Field ABC. C A B Place three marks at the angles A, B and C, begin to measure at A towards B, allow the length of AB to be 1785. will ftand thus: The notes in the field-book Left of B 1785 AB begin at A Measure BC, allow its length to be 907, write this above the laft notes thus: Left of C 907 BC L of B 1785 AB begin at A Measure the other line CA 1400, which write above the last notes thus: |
