NS 4634 7335 to NS 4650 7330 The published survey (OS 50 inch 1964) was revised. No surface trace across arable fields. Macdonald's (1932) line, linking various trenching results, somewhat conflicts with the clear cropmark evidence of the Ditch-line in CUCAP aerial photograph V75. Using Macdonald's measurements with aerial photographs and ground detail the line has been adjusted, introducing a further alignment position compatible with ground contours. A possible marker trench, parallel with the Ditch, shows on above aerial photograph.
