The Genesee, the principal natural feature of its district, rises on the Grand Plateau or table-land of Western Pennsylvania, runs through New York, and flows into Lake Ontario, at Port Genesee, six miles below Rochester. At the distance of six miles from its mouth are falls of 96 feet, and one mile higher up, other falls of 75 feet.1 Above these it is navigable for boats nearly 70 miles, where are other two falls, of 60 and 90 feet, one mile apart, in Nunda, south of Leicester. At the head of the Genesee is a tract six miles square, embracing waters, some of which flow into the gulf of Mexico, others into Chesapeake Bay, and others into the Gulf of St. Lawrence. This tract is probably elevated 1,600 or 1,700 feet above the tide waters of the Atlantic Ocean.
