HELSTON, a town of Cornwall in England, seated on the river Lowed, in W. Long. 5. 45. N. Lat. 50. 8. It contains about 400 houses, is well inhabited, and sends two members to parliament. The steeple with its spire, which is about 90 feet high, is a notable sea-mark. A little below the town is a harbour where several tin-ships take in their lading, and here is the largest market-house in the county. The inhabitants neither pay to the church nor poor, these being supported by the revenues of the town.
