It is not surprising, therefore, to find that Washington, soon after reaching Mount Vernon, at the close of the war, determined on another western journey. The ostensible reason for the trip was to look after his lands, but from the journal of the traveller it is easy to see that the important result of the trip was a personal inspection of the means of communication between the various branches of the Ohio and the Potomac, which so nearly interlock in southwestern Pennsylvania and northeastern West Virginia. It must be remembered that in that day river navigation was considered the most practical form of transportation. All the rivers of Virginia, great and small, were the highways of the tobacco industry; the rivers of any colony were placed high in an inventory of the colony's wealth, not only because they implied fertility, but because they were the great avenues of trade. The first important sign of commercial awakening in the interior of the colonies was the improvement of the navigable rivers and the highways.
In less than thirty-three days Washington travelled nearly seven hundred miles on horseback in what is now Pennsylvania and West Virginia.[1] That he did not confine his explorations to the travelled ways is evident from his itinerary through narrow, briery paths, and his remaining for at least one night upon a Virginian hillside, where he slept, as in earlier years, beside a camp-fire and covered only by his cloak. His original intention was to go to the Great Kanawha, where much of his most valuable land lay, and after transacting his business, to return by way of the New River into Virginia. But it will be remembered that after the Revolutionary War closed in the East, the bloodiest of battles were yet to be fought in the West; and even in 1784, such was the condition of affairs on the frontier, it did not seem safe for Washington to go down the Ohio. He turned, therefore, to the rough lands at the head of the Monongahela, in the region of Morgantown, West Virginia, and examined carefully all evidence that could be secured touching the practicability of opening a great trunk line of communication between East and West by way of the Potomac and Monongahela rivers. The navigation of the headwaters of the two streams was the subject of special inquiry, and then, in turn, the most practicable route for a portage or a canal between them.
