Major differences in former [illegible] sight resolved by assuming variations in reading No, due to causes unknown. [The theodolite compass seems very sensitive]
Readings at (C increased by 6' (D " " 3' (E diminished " 3 1/2' (F " " 6' " GC & GD " " 1'
Inconsistencies then remaining are reconciled as seems best: EC > by 1 1/2' EG > by 1 1/2' EF < by 1 1/2' FC > " 1/2' FE > " 1/2' Readings at H diminished by 2' FH > by 1 1/2' HD > by 1' DH < by 1'; HC > 1/2 CH < 1/2 Readings at A increased 5' " " B diminished 6' AB > by < by 1 1/2' AH < by 1 1/2' } to agree with BA - HA - FA AF < by 1' CB > by 2 1/2' - to agree with BC
To make △ CEF + CDF consistent with the others read CF 168° 4' & FC 348° 4'
EH > 1/2' HE > 1/2' HF < 1/2'
