20 THE ESSEX NATURALIST. arable farming that was comparable with that of the Boulder Clay parishes. It therefore appears that, in spite of local differences, well over eighty or ninety per cent, of the land of South-East Essex was devoted to arable farming during the earlier decades of the. nineteenth century. The effect of the high wheat prices of the time had obliterated any regional differentiation due to varying soil characters. A hundred years later, with normal or sub-normal conditions, the effect of the three soil-types is clearly reflected in the Land Utilisation map for the year 1933 (fig. 6). Important regional differences, however, also existed in Essex in the early nineteenth century. An assessment of the value of the real estate drawn up in 1815 shows that the dif- ferences between the north-west and south-east, that have been observed in earlier periods, still existed. In view of the wide- spread nature of the arable farming of the County we may assume that the. crops of the south-east were either poorer in quality, or of a different type, from those of the north-west. Some support is given to both these suggestions by Norden in earlier years and Arthur Young22 at the beginning of the nineteenth century. The former writer mentioned the north- west as a land of rich corn and hop crops; the south-east as a country of oat crops. Young noticed the difference in the rotation of crops, since wheat predominated in the former district, whilst oats and fallows figured principally in the south- east. It is not unlikely that the north-western area grew corn crops for milling, whilst the corn of the south-eastern districts served not only for milling, but also for cattle fattening. Much of the corn of the latter area is used for this purpose today. An interesting point is raised by the economy of a former (1838) detached area of Asheldam which is situated upon the coastal marshland of the Dengie Hundred. This land seems to have provided the main pasture land of the Parish, although about one third was arable land. In 1933 the same district showed a further third in cultivation. During the intervening period the extensive area of marshland arable farming, that is noticeable in the Land Utilisation map, must have made its appearance. This may possibly have occurred during the sixties, 22 Young, A. General View of the Agriculture of the County of Essex
