ENCLOSURES: ESSEX AGRICULTURE, 1500-1900. 3 Roman and Saxon settlement patterns appear to have exercised a dominant control on the progress of enclosure in the County, and their varied field systems merit detailed description. The similarity between the British and the Roman settle- ment types and their attendant field systems is very close. The British type of settlement was the hamlet or "trev" system, and the cultivated area was to be found spreading uninterruptedly around the farm. In certain northern districts of Britain a similar hamlet type of cultivation existed until a century or so ago, and was known under the local names of "run-rig" and "run-dale." In this type of holding the culti- vated plots were retained by one farmer for a number of years before a redistribution took place, and, no doubt, this British agricultural system would provide a strong incentive to the cultivator to fence his plot. The ease with which the land could be enclosed is obvious. In the Roman cultivation system the centuriae or, holdings were regularly laid out each with its vicus or hamlet.2 The individual holdings were quite separate, and the principal difference between the Roman settlement system and that of the British was the regular and rectilinear pattern customarily associated with Romans. Obviously enclosure could be carried out with the same ease as in the case of the British cultivated areas. In the areas settled by Saxons an entirely different field system is encountered. Here the well-known three-field system flourished in which each villein had his several strip-like areas scattered over the three fields. His work, therefore, lay in various parts of the parish, and a central nucleated settlement was necessary and, indeed, typical. It has been suggested elsewhere by the writer that these Saxon villages could be subdivided into linear and rosette types—-the former being the lengthy single street village, so common in parts of Essex, whilst the rosette village is the compact settlement with a small nexus of roads, and is taken to indicate Saxon settlements within the forested districts. It seems possible that the Saxon three-field system may have shown some modification when associated with the rosette villages, necessitated by forest conditions. 2 See also Essex Naturalist, vol. xxiv., p. 122.
