CHILTERN, a chain of chalky hills forming the southern part of Buckinghamshire, the northern part of the county being distinguished by the name of the Pale. The air on these heights is extremely healthful: The soil, though stony, produces good crops of wheat and barley; and in many places it is covered with thick woods, among which are great quantities of beech.—Chiltern is also applied to the hilly parts of Berkshire, and it is believed has the same meaning in some other counties. Hence the HUNDREDS lying in those parts are called the Chiltern Hundreds.
