a town of the United States of North America, state of New York, built on both sides of the Oswego River, where it enters Lake Ontario, 35 miles N.N.W. of Syracuse, and 183 N.N.W. of Albany. The river, which is here about 230 yards broad, is crossed by a bridge. The houses and public buildings are handsome; and the streets are straight, broad, and regularly laid out. Oswego has eleven churches, two of which, belonging to the Presbyterians, are remarkable for size and elegance. There are also a court-house, custom-house, two banks, an academy, and other educational institutions. Several newspapers are published in the town. The river, which has falls a short distance above the town, affords water-power for the various manufactories of the place, consisting of ten or twelve large flour-mills, and a starch factory employing about 100 hands. The commerce of Oswego is extensive, and rapidly increasing; its position gives it great advantages for intercourse with Canada, nearly half of the trade of the United States with that country passing through Oswego. The imports from Canada to this port in 1855 amounted in value to more than L.1,250,000; and the whole value of imports and exports in that year was about L.8,000,000. The harbour is one of the best on the United States side of the lake, having a pier 1200 feet in length. On the E. side of the river stands Fort Oswego, built by the government for the protection of the town and harbour. The shipping of the port, enrolled and licensed, had in 1852 a total tonnage of 26,107; and during the year ten ships were built, with a tonnage of 765. In the same year the vessels that entered were 1784, tonnage 240,253; those that cleared were 1731, tonnage 234,825. Pop. (1850) 12,205; (1855) estimated at 16,000.
