THEY show, by inspection, the alteration of latitude and departure to every degree on the compass, and that for any distance not exceeding 100.000 links. In the uppermost rank of every division are placed the several angles and their complements, to 45°, including the quarter, half, and threequarters of degrees; and in the left-hand column are lengths of the measured lines of the fieldwork, and in the common areas are the difference of latitude and departure. EXAMPLES. Suppose the angle to be N. E. 271⁄2 degrees, and the line in the field measured to 6 chains, and it be required to find the Northings and Eastings of that station, under 27 degrees, and answering to 6 in left-hand column, the number in the com (120) |
