It is frequently necessary to make surveys of ranger stations or for timber sales in areas which have not been previously surveyed or mapped. It is imperative that some connection should be surveyed between the near- est or most convenient established point and the initial point of the survey which is to be made. Otherwise the survey will not determine the location of the area under consideration. The nature of the ...country and the dis- tance necessary to be run will suggest which of the fol- lowing methods may be employed: (1) Measure a line north, south, east, or west to in- tersect a Government survey line. Then tie to the nearest corner, quarter corner, meander corner, mile- post, grant corner, or other point which is of official record. (2) Or run a traverse (meander) over a road, trail, open or easy country to such points. (3) Or if no land office surveys have been made nearer than, say, 5 miles, but there is a Geological Sur- vey sheet, then tie to a bench mark, triangulation sta- tion, forks of a road, forks of a stream which has not changed its bed, or a house which is shown on the sheet.
