[40] The 1/2500 Ordnance map of Kent (LV. 10) seems to me to commit a slight error at this point. There is no need to take the Old Road through the gas works. It obviously goes south of the lodge, curls northwards on leaving the park, and is lost in the buildings near the smithy. After this it forms the lane which bounds to the north the fields marked 111 and 119.
[41] Here again the 25-inch Ordnance for Kent (LV. 10) draws a conventional straight line which seemed to us erroneous. We took it to go from near Brewhouse Farm along the raised footpath to Whitehill, and then (LV. 6) under the pit, across fields 13 and 67 (not down by Soakham Farm as the map gives it), and so on to the turf where is a raised embankment and a characteristic line of yews.
[42] Professor Boyd-Dawkins in connection with his examination of the iron implements found in Bigberry Camp has traced the Old Road for a mile or two westward. The map may be seen in Owens College at Manchester.
[43] I would trace it more or less as follows on the 25-inch Ordnance map for Kent (XLIV. 16):—Through the orchards marked 378, 379a there just south of Bowerland, down the valley beyond, and up to Knockholt. But it is all cultivated land, and except for a footpath at the end there is no trace left.
