In our story of Washington as promoter and prophet it was seen that at the close of the Revolution the late commander gave himself up at once to the commercial problem of how the Potomac River might be made to hold the Middle West in fee. Passing westward in the Fall of 1784, he spent a month in the wilds of Northern Virginia seeking for a pathway for canal or road from the South Branch of the Potomac to the Cheat River. The result of his explorations was the classic letter to Harrison in 1784, calling Virginia to her duty in the matter of binding the East and West with those strongest of all bonds--commercial routes bringing mutual benefit. The immediate result was the formation of the Potomac Company, which proposed to improve the navigation of the Potomac from tide-water, at Washington, D. C., to the highest practicable point, to build a road from that point to the nearest tributary of the Ohio River, and, in turn, to improve the navigation of that tributary. One stands aghast at the amount of money spent by our forefathers in the sorry attempt to improve hundreds of unnavigable American rivers. You can count numbers of them, even between the Mohawk and Potomac, which were probably the poorest investments made by early promoters in the infant days of our Republic. When, in the Middle Ages, river improvement was common in Europe, it was proposed to make an unnavigable Spanish river navigable. The plan was stopped by a stately decree of an august Spanish council on the following grounds: "If it had pleased God that these rivers should have been navigable, He would not have wanted human assistance to have made them such; but that, as He has not done it, it is plain that He did not think it proper that it should be done. To attempt it, therefore, would be to violate the decree of His providence, and to mend these imperfections which He designedly left in His works." It is certain that stockholders in companies formed to improve the Potomac, Mohawk, Lehigh, Susquehanna, and scores of other American streams would have heartily agreed that it was, in truth, a sacrilege thus to violate the decrees of Providence.
