For distributing the departure in this problem of the closing distance,
we have used the Compass Rule. The total distance to the corner
to be adjusted is to the total length of all courses as the departure
adjustment to the corner in question is to the departure of the
closing error or . . .

. . . or A1 is to A as B1 is to B in the drawing. With the latitudinal
line the principle is the same, single-proportion when parallel
to the line. Compass Rule when perpendicular to the line, but special
allowances must be made for geodetic curvature of the line.

On a latitudinal line the temp stakes should be placed to suit
the usual adjustments for curvature. Of course, if the record bearings
were rotated to correct for curvature, that is, you are running
mean, then no further corrections need be applied.
