ENCLOSURES : ESSEX AGRICULTURE, 1500-1900. 17 the close of the eighteenth century arable farming was increasing at the expense of pastoral farming. In the same map of Chapman and Andre, it is possible to trace some evidence for the theory put forward regarding the regional division of arable and pastoral farming during the earlier years of the period now under examination. Local differences in soil would not be of great importance in a sheep farming country, but might well be significant in a district devoted to arable cultivation. Therefore, at a time when the period of rapid enclosures was concluded, we are not surprised at the distribution of commons in the County. It must be borne in mind that we have been tracing the enclosures of cultivated land for both arable and pastoral farming. It is now proposed to consider the history of the commons. Maps of the time show that, in 1775, few commons remained through- out the London Clay area, whilst very few had been recently enclosed.19 The suggested explanation is that, during the period of the preceding two or three centuries, when the rapid Conversion of this district to pastoral farming occurred, there was no need to distinguish between the improved land and the poorer land of the commons. Therefore, the comparative absence of commons, or of recently enclosed commons, within the London Clay area in 1775 supports the contention that pastoral fanning had been widespread over this district during the preceding two or three centuries. Most of the unenclosed commons of this district remain as such today, and are sterile tracts. In the north and centre the main mass of the Boulder Clay had many unenclosed, and not a few enclosed, commons at this time. The former may denote the predominance of arable farming, whilst the latter suggest fresh enclosures for arable farming. Something has already been said regarding the later increase of corn growing. An interesting feature of the distribution of unenclosed commons at this time is the large number remaining in the three " Saxon areas " of champion holdings, and the rarity of recently enclosed commons. Although we know they were, in the main, arable areas—as the presence of numerous unenclosed com- mons would confirm—the fact that the great majority were 19 It Is assumed that a common had been comparatively recently enclosed when the common is no longer in existence, yet the name is still present.
