LAMBTON, a township in that part of the parish of CHESTER-le-STREET which is in the northern division of EASINGTON ward, county palatine of DURHAM, 8 miles (N. N. E.) from Durham, containing 293 inhabitants. Harraton hall, the ancient seat of the D'Arcys, stood on the side of Lambton castle, which is situated in a beautiful park five miles in circuit, and intersected by the river Wear. Just within the entrance is the site of an ancient chapel; and near it Worm hill, of which tradition says that it was anciently occupied by a formidable serpent, which was cut to pieces by some hero of the Lambton family, cased in armour set with razors for the purpose. Two brine springs, from which salt is made, issue from the bottoms of two coal pits in the neighbourhood.
