HUDSON RIVER, a river in New York State, and one of the most beauti ful and important in America. It rises in the Adirondack Mountains, 4,326 feet above the level of the sea, its head streams being the outlets of many moun tain lakes. At Glen's Falls it has a fall of 50 feet, and soon after, taking a S. course, runs nearly in a straight line to its mouth at New York City. It is tidal up to Troy, 151 miles from its mouth. Below Newburgh, 60 miles from New York, the river enters the highlands, which rise abruptly from the water to the height of 1,600 feet. Here historical associations add to the interest of scen ery of singular beauty and grandeur: here was the scene of Arnold's treason and of Andre's fate; and at West Point, the seat of the United States Military Academy, 8 miles below Newburgh, are the ruins of Fort Putnam, built during the war of independence. Emerging from the highlands, the river widens into a broad expanse called Tappan Zee, which is 41/2 miles wide and 13 long. Below, on the right bank, a steep wall of trap rock, called the Palisades, rises from the river's edge. The river from here
is known as the North river, and after passing between New York and Ho boken and Jersey City, it falls into New York Bay. Its whole length is about 350 miles, and its principal tributaries are the Sacondaga, Mohawk, and Wall kill. The river, named from the Eng lish navigator who explored it in 1609 (see HUDSON, HENRY), iS connected by canals with Lakes Erie and Champlain, and with the Delaware river. There are three double-tube tunnels under the North river, one opposite 34th Street, one opposite Washington Square, and one opposite Cortlandt Street. Robert Fulton's first successful experiment in steamboat navigation was made on this river in 1807.
HUE (118-5'), the capital of Anam, a French protectorate 10 miles from the mouth of the Hue river, or Truongtien. In 1801 it was strongly fortified by French officers. Since the treaty of Hue in 1884 there is a French garri:on in Thuanan, the port of Hue. There is little industry in Hue, which has a popu lation with suburbs of about 65,000. See ANAM.
