(726) The magnetic variation is (determined by subtracting
the present bearing from B to C, viz., N 60° 15' E
from the original bearing, viz., N 62° 00' E. The differ-
ence is 1° 45' and a west variation; hence, to determine
the present bearings of the boundaries we must add
the variation to an original bearing, which was N W or
S E, and subtract it from an original bearing, which
was N E or S W. The corrected bearings will be as
follows :
