12 THE ESSEX NATURALIST. arable land to pasture land within the London Clay area. There is, furthermore, a possible reason for the absence of enclosures within the remaining four parishes. We may consider that they were either already enclosed or suffered this fate at a later date, although no mention of this incident appears in later records. It may be mentioned, however, that these four parishes, and one of the former nine, contain areas of sandy soil—the remainder of the parishes of the hundred having London Clay soil. At the present time these five parishes contain the greater part of the arable land of the district, whilst the London Clay country Fig. 2.—Known Essex Enclosures, 1400-1600. bears grassland (Fig. 6). It is therefore conceivable that the enclosures within the four former parishes occurred early, and were perhaps for arable farming—a proceeding that did not cause the great outcry following eviction that pastoral enclosures produced. It should, also, be borne in mind that these four parishes lay to the north of the hundred near Romanised areas, and perhaps were more easily, and so earlier, enclosed. In any case we have concrete evidence for later and large en- closures for pastoral farming within the "Saxon" London Clay area (Fig. 2).
