Andover, a post-town In the county of Hillsborough, is situated in latitude 43° 27′ north, and is bounded on the north by New-Chester, east by the Pemigewasset river, a branch of the Merrimack, which separates the town from Sandbornton; south by Salisbury, and west by Wilmot—in length about ten miles from east to west; its average width four miles from north to south—containing 29,883 acres, or nearly forty-six square miles.

These branches unite soon after crossing the westerly
