CENTURIATION IN ESSEX. 207 by the heavier soil. From the distribution of the Pedestal urns of these Belgic, folk it may be assumed that the majority of their settlements occurring beyond the light sandy soils were on the Eastern London Clay. This large area was more lightly wooded than the central Boulder Clay region, approximating in the lightness of its woodland covering to the northern fringe of the chalky Boulder Clay area. Here, as we have seen, other pedestal urns have been found. This distribution of settlement seems to indicate that, whilst forest covering and heaviness of soil had both been almost insuperable difficulties to earlier pre- historic, peoples, only the former provided an obstacle to the La Tene III settlement. We may therefore state with some- certainty that the standard of agriculture practised in Essex was sufficiently high to satisfy the requirements of Roman Centuriation. For some time before Caesar's first visit the inhabitants of Essex had been influenced by the Roman civilisation. Indications also exist in writings of the time to the effect that the resources of south-east Britain were known with fair certainty; reference to the corn-growing of the district appearing in both Strabo and Caesar.4 Caesar had also noticed the "zoning" of the Belgic and the earlier British settlers. "Britanniae pars interior ab eis incolitur quos natos in "insula ipsi memoria proditum dicunt, maritima pars ab "eis . . . ex Belgia transierant ..." (B.G., v. 12). It is, however, impossible to gather any detailed information regarding Essex from Caesar or any other contemporary writer, but we do know that during the decades immediately preceding the Roman Conquest rapid strides were made by the south- eastern British in acquiring Roman habits. The Trinovantes of Essex had recently come under the rule of Cunobeline, who, it seems, had received a Roman education at the court of Augustus.5 We may ascribe the important changes he introduced into Essex to his probable acquirement of Roman culture. During his reign the capital of the Cassivellaunian dynasty was shifted from the vicinity of St. Albans to Camulodunum, near the present-day Colchester. The reason for such a move is 4 The greatest amount of corn was probably grown in Kent during this period, but it is probable that Essex contributed no trifling amount to the total production. 5 Geoffrey of Monmouth.
