Comparatively blank spaces occur in this place-name dis- tribution in the areas around Colchester and Barstable— districts appearing heavily settled in Romano-British times. Perhaps the invaders may here have been kept at bay for some time by the British inhabitants, or the former may have peace- fully superseded the Roman as a landlord, adopting the existing nomenclature. The apparent occurrence of Celtic elements in the place-names of these regions may indicate either possi- bility, and since the areas were highly populated in Norman times we may preclude the possibility of their desolation and reconquest by the forest in early Saxon times. The second period Saxon place-name endings,5 whilst re- peating the same features to a limited extent in their distribution, indicate a greater concentration within the Boulder Clay and eastern London Clay areas. From these two place-name distributions we may draw some conclusions as to the state of the forest in Saxon times. It would appear that the Saxons continued the work, begun in a slighter measure by the La Tene III. people, of clearing the woodland. They seem to have rapidly settled the three light soil areas and the eastern London Clay, and had actively begun to clear the Boulder Clay forest. Collingwood, Wheeler and others, apparently forming their opinion from Latin accounts of the Saxons' Teutonic forbears, hold that the Saxon was both able and desirous of clearing wooded country and settling thereon. The Saxons in Essex certainly appear to have behaved in such a way. Thus whilst the La Tene III. people began a great clearing movement into the scantily wooded eastern London Clay, the Saxons inaugurated a similar movement into the more heavily forested Boulder Clay; the new invaders presumably settling the already cleared land in their first advance. The numerous Saxon place-names relating to vegetational conditions suggested the possibility of tracing the bound; of the Forest on the evidence that these names afford (Fig. 4).
