ed. Theelementary, often practised, but es-sentially bad method, would be tochain from A to C, and take offsetson each side oi AC to the salientpoints of the boundary. This wouldbe a bad, or at least untrustworthymethod, (i) because the offsets arelong, and the perpendiculars mustbe laid out with… … S6 SIMPLE LAND SURVEY offsets to the boundary along each chain line. The offsets are now short, and are easy to measure with sufficient accuracy. Do the same from a to d, and from d to c. But now note that the construction on ^^--l^-^ our plan of the triangles adc, adc, ^^^^^^ ^^^^^v^ depends on…
