After outlining the route of the road, the Commissioners summed up matters as follows: "... it will lay about twenty-four and a half miles in Maryland, seventy-five and a half in Pennsylvania, and twelve miles in Virginia; ... this route ... has a capacity at least equal to any other in extending advantages of a highway; and at the same time establishes the shortest portage between the points already navigated, and on the way accommodates other and nearer points to which navigation may be extended, and still shorten the portage.... Under these circumstances the portage may be thus stated: "From Cumberland to Monongahela, sixty-six and one-half miles. From Cumberland to a point in measure with Connelsville, on the Youghiogeny river, fifty-one and one-half miles. From Cumberland to a point in measure with the lower end of the falls of the Youghiogeny, which will lie two miles north of the public road, forty-three miles. From Cumberland to the intersection of the route with the Youghiogeny river, thirty-four miles.... The point which this route locates, at the west foot of Laurel Hill, having cleared the whole of the Alleghany mountain, is so situated as to extend the advantages of an easy way through the great barrier, with more equal justice to the best parts of the country between Laurel Hill and the Ohio. Lines from this point to Pittsburg and Morgantown, diverging nearly at the same angle, open upon equal terms to all parts of the western country that can make use of this portage; and which may include the settlements from Pittsburg up Big Beaver, to the Connecticut reserve, on Lake Erie, as well as those on the southern borders of the Ohio and all the intermediate country." Thus it is clear that our one great national turnpike was, in reality, a portage path. Upon this same general principle many of our first highways were built, in an era when inland water navigation, on canal and river, was considered the secret of commercial prosperity. With the building of canals, the ancient portages again became prominent because of geographical position; in every state the portage paths marked the summit levels. In the cases of such important works as the Erie Canal and the Ohio Canal the portages between the Mohawk and Wood Creek in New York and between the Cuyahoga and Tuscarawas in Ohio were of vital importance. In many instances, at the points where the old portages mark the spots of least elevation, two canals are found converging from three or four valleys. It is quite impossible for us to realize the importance attached to the portage routes in days when steam navigation and locomotion were not dreamed of. This is suggested by the clause of the famous Ordinance of 1787 in which they were again declared to be "common highways forever free." Washington's serious study of this subject is exceedingly interesting--not less so because many of his plans which seemed to many idle dreaming were completely realized not long after his death.[34]
