Hudson River is in the state of New York, United States of America, taking its rise in the northern part of the state, where its eastern and western branches have a course of 40 miles before uniting to flow 15 miles S.E. to Hadley Falls, then a rather longer distance N.E. to Glen's Falls, and then almost S. to New York Bay. Shortly below the junction of the streams the Sacandaga flows into the river, and 40 miles below Glen's Falls the Mohawk joins the stream. Many towns are upon the river, among them being New York, Albany, Hudson, Poughkeepsie. and Troy. The last lis miles of the course of 350 miles are navigable for large vessels, and steamboats ply as far as Albany, 145 miles above the mouth. The scenery is often compared to that of the Rhine.
