“Parliamentary inclosures are scarcely ever so complete and general as” (non-Parliamentary enclosure) “in Norfolk” (“Eastern Tour,” Vol. II., p. 150).
William Marshall supplies a confirmatory note. “Norfolk, it is probable (speaking generally of the county), has not borne grain, in abundance, much above a century. During the passed century” (the eighteenth) “a principal part of it was fresh land, a newly discovered country in regard to grain crops” (“Review of the Reports to the Board of Agriculture for the Eastern Department,” p. 314).
Enclosure in the western half of Norfolk and along the central chalk ridge in the eighteenth and nineteenth centuries, whether common field arable were included or not, meant the reverse of what it had meant in the first half of the sixteenth century—the conversion of land from sheeprun to arable land and to highly cultivated land. Kent, in a second edition of his report of Norfolk, published in 1796, estimated that two-thirds of the whole area of the county was then arable; and of the arable land three-quarters was enclosed, one-quarter in common field. In other words, one-half of the area of the county was enclosed arable, one-sixth common field arable. The remainder he describes as follows:
| Meadows, parks, and upland pasture | 126,692 | acres. |
| Unimproved commons | 80,000 | ″ |
| Marsh lands | 63,346 | ″ |
| Warrens and sheepwalks | 63,346 | ″ |
