SOMERSET is one of the S.W. counties of England. On the N. it is washed by the Bristol Channel; on the N.E. the Avon, like a silver streak, divides it from Gloucestershire; it is bordered on the E. by Wiltshire; its S.E. neighbour is Dorset; and on the S.W. it touches Devon. Its shape is so irregular that dimensions give a misleading indication of its extent.
