Cumberland county. This township comprises a promontory in Casco bay, formerly Merrycomeag, and several islands surrounding it, the largest of which is called Sebascodegan. The waters which enclose this territory are so situated, at the northern and eastern extremity of Casco bay, that a canal of about a mile in length would unite them with Kennebec river near Bath. The soil of Harpswell is very fertile, and the location delightful in summer. It is a resort for invalids and parties of pleasure. The people are principally engaged in farming and fishing. It lies 22 miles N.E. from Portland by water, and 4 miles S.E. from Brunswick. Incorporated, 1758. Population, 1837, 1,344.
