There was never a time, probably, when the white man, conversant with the rivers and lakes of New York, did not talk of a continuous passage by water from Lake Erie to the sea. As early as 1724, when Cadwallader Colden was surveyor-general of the colony, he declared the opportunity for inland navigation in New York without a parallel in any other part of the world, and as the Mohawk Valley, reaching out toward the lakes of Oneida and Cayuga, and connecting by easy grades with the Genesee River beyond, opened upon his vision, it filled him with admiration. Even then the thrifty settler, pushing his way into the picturesque country of the Iroquois, had determined to pre-empt the valleys whose meanderings furnished the blackest loam and richest meadows, and whose gently receding foot-hills offered sites for the most attractive homes in the vicinity of satisfactory and enduring markets. It was this scene that impressed Joseph Carver in 1776. Carver was an explorer. He had traversed the country from New York to Green Bay, and looking back upon the watery path he saw nothing to prevent the great Northwest from being connected with the ocean by means of canals and the natural waterways of New York. In one of the rhetorical flights of his young manhood, Gouverneur Morris declared that "at no distant day the waters of the great inland seas would, by the aid of man, break through their barriers and mingle with those of the Hudson." George Washington had visions of the same vast system as he traversed the State, in 1783, with George Clinton, on his way to the headwaters of the Susquehanna.
