Buckingham is traversed by the Chiltern Hills, and so is divided into two distinct regions. About half the county lies north-west of the Chilterns, on a sub-cretaceous formation, like Bedfordshire, with fertile soil, and villages thickly scattered. The remainder consists of the chalky downs and the later formations, like most of Hertfordshire and Middlesex. The enclosure of the south-east portion was earlier than that of the north-west part. Arthur Young in 1771 was much struck by the extent of the open fields in the latter part. The vale of Aylesbury,[100] he says, was good clay, and open field (“Eastern Tour,” p. 18). From Aylesbury to Buckingham “nearly the whole country is open field, the soil among the richest I ever saw, black putrid clay” (p. 19). “As for the landlords, what in the name of wonder is the reason of their not enclosing! All this vale would make as fine meadows as any in the world” (p. 23). However, about Hockston (Hoggeston) he saw many new enclosures (p. 24). Hoggeston itself was never enclosed by Act, but several neighbouring villages had been enclosed by Acts passed previously to 1771. [100] An Act for the enclosure of the common field land of Aylesbury itself was passed in the same year. Celia Fiennes passed through the same part of Buckinghamshire about eighty years before. From Stony Stratford to Great Horwood, she says, “this country is fruitfull, full of woods, Enclosures, and rich Ground. The little towns stand pretty thicke. You have many in view” (p. 97). This does not imply anything more than very partial enclosure; for Celia Fiennes, accustomed to the complete absence of hedges of her own part of Wiltshire, always notices enclosure rather than the absence of enclosure. That many little towns should be in sight of one passing through a flat country implies that it is open, except close to the villages. Leland, in 1536, came from Bedfordshire along the boundary between Herts and Bucks and into the extreme south of Buckinghamshire, and found that enclosures had already begun. He describes the whole county in one luminous sentence, “Looke as the countrye of the Vale of Alesbury for the most part is clean barren of wood, and is champaine, soe is all the Chilterne well woodid and full of Enclosures” (fol. 192 a). It seems quite clear, then, that the enclosure movement of the south-east of Berkshire was ancient; that it moved up the long slope of the Chilterns from the Thames and Middlesex, but stopped at the open chalk downs which marked the summit of the range; and that the movement which affected the enclosure of the Vale of Aylesbury and all north-western Buckinghamshire was part of the general enclosure movement of the Midlands, spreading southwards from Leicester and Northampton, as we have seen it spread eastwards.
