a circle in the department of Coblentz, in the Prussian province of the Lower Rhine. It extends over 212 square miles, and in 1849 contained 21,882 inhabitants, all Catholics, except 8 Jews and 64 Protestants, in one city, four market towns, and 104 villages. It is watered by the river Ahr. It is generally a hilly and woody country, where little corn except oats grows, and where the chief subsistence is potatoes. Cattle and sheep are bred with tolerable success; and potashes and charcoal are made from the forests. There is some little employment furnished by spinning and weaving both linens and woollens on a small scale. The chief place of the same name contains 1450 inhabitants.
