The town is said to have sent members to Parliament so early as the reign of Henry III., when the privileges of markets and fairs were granted; but the first authentic return was in the reign of Queen Elizabeth. In the time of Henry III. the manor and lordship of Callington were vested in the family of Ferrers, by a grant from the earls of Cornwall; the possession has passed by heiresses to several families; and finally, through Dennis, Rolle and Walpole, to Mr. George William Trefusis of Trefusis, in Milor; together with the barony in fee of Clinton, created by a writ directed John de Clinton, 17 Edward I. A.D. 1299. His grandson sold the property to Mr. Alexander Baring, at a period when some adventitious circumstances, no longer in existence, added materially to its value. The church and town are handsome specimens of the gothic architecture which distinguishes the west of England; and there exist several ancient monuments of individuals formerly lords of the manor. This parish contains 2387 statute acres.

GEOLOGY, BY DR. BOASE. The north-eastern part of this parish extends to the east of Kitt Hill, the most elevated point of Hingston Downs, which is composed of granite. The slate adjoining thereto resembles that which occurs in similar situations in the parishes of St. Austell and St. Blazey; and this district has been the scene of considerable mining speculations. In former ages it abounded in stream tin to such an amount that the Cornishmen of those days expressed their opinion of its value by the distich Hengsten Down, well yrought Is worth London town, dear ybought. _Carew, Lord Dunstanville’s Edition, p. 272._ As the town of Callington is approached, the slate becomes of a darker blue, and passes into hornblend rock, which prevails in the other parts of the parish, and in several places so much abounds in quartz as to form barren downs. This rock, however, has not any marked character, and it is not often exposed to view; near St. Ive it appears to graduate into the calcareous series. CALSTOCK. HALS.
