COLLING, ROBERT (1749-182o), and CHARLES (1751-1836), English stock breeders, famous for their improve ment of the Shorthorn breed of cattle, were the sons of Charles Colling, a farmer of Ketton, near Darlington, where Charles con tinued to farm, while Robert took a farm at Barmpton. An ani mal which Robert bought on Charles's advice for i8 and after wards sold to his brother, became known as the celebrated "Hub back," a bull which formed the basis of both the Ketton and Barmpton herds. The two brothers pursued the same system of "in and in" breeding which they had learned from Robert Bake well (q.v.), and both the Ketton and the Barmpton herds were sold by auction in the autumn of 1810. The former, with 47 lots, brought L7,116, and the latter, with 61 lots, L7,852. Robert Colling died at Barmpton on March 7, 182o. Charles Colling owned the famous bulls "Hubback," "Favourite" and "Comet." He died on Jan. 16, 1836. (See AGRICULTURE ; ANIMAL BREEDING, etc.) The Journal of the Royal Agricultural Society, 1899, contains a biographical sketch of the brothers Colling.
