8. The occurrence of worked flints along with Roman remains 
at Great Chesterford and with Iron Age or Early Roman pottery 
at Chiswick Hall suggests an enquiry as to a Post-Neolithic 
date for these sites, but until further chronological evidence

culture intermediate to the Cissbury and late Neolithic type. 
9. The correlation of patination to the character of the soil 
is suggestive and may be summarised as :— 
Soil with much humus, black and unpatinated. 
Chalk soil, white patina. 
Sandy loam, greyish glaze to blue mottle. 
Clay loam, blue mottle. 
Clay, greenish glaze.to “ toad-belly ” and ochreous type.
