So this grant line adjustment technique is much like single-proportion, but applied to the grant area only. Many grant boundary field notes call for natural objects of topography as part of the boundary description. These calls, such as saddles, ridge tops and spurs are given precedence in controlling the restoration of lost corners along the grant boundary.

The field notes called for the boundary to follow the top of Blue Ridge until it turned westerly. No adjustment of restoration should place the angle point other than on the ridge as was indicated in the original notes. The natural topographic calls and objects such as boulders, or trees are given precedence to record distances and bearings.
