A person cannot live in the American Central West and be acquainted with the generation which greets the new century with feeble hand and dimmed eye, without realizing that there has been a time which, compared with today, seems as the Middle Ages did to the England for which Ruskin wrote--when "life was intermingled with white and purple." This western boy, born to a feeble republic-mother, with exceeding suffering in those days which "tried men's souls," grew up as all boys grow up. For a long and doubtful period the young West grew slowly and changed appearance gradually. Then, suddenly, it started from its slumbering, and, in two decades, could hardly have been recognized as the infant which, in 1787, looked forward to a precarious and doubtful future. The boy has grown into the man in the century, but the changes of the last half century are not, perhaps, so marked as those of the first, when a wilderness was suddenly transformed into a number of imperial commonwealths. When this West was in its teens and began suddenly outstripping itself, to the marvel of the world, one of the momentous factors in its progress was the building of a great national road, from the Potomac River to the Mississippi River, by the United States Government--a highway seven hundred miles in length, at a cost of seven millions of treasure. This ribbon of road, winding its way through Maryland, Pennsylvania, Ohio, Indiana, and Illinois, toward the Mississippi, was one of the most important steps in that movement of national expansion which followed the conquest of the West. It is probably impossible for us to realize fully what it meant to this West when that vanguard of surveyors came down the western slopes of the Alleghenies, hewing a thoroughfare which should, in one generation, bind distant and half-acquainted states together in bonds of common interest, sympathy, and ambition. Until that day, travelers spoke of "going into" and "coming out of" the West as though it were a Mammoth Cave. Such were the herculean difficulties of travel that it was commonly said, despite the dangers of life in the unconquered land, if pioneers could live to get into the West, nothing could, thereafter, daunt them. The growth and prosperity of the West was impossible, until the dawning of such convictions as those which made the Cumberland Road a reality. The history of this famed road is but a continuation of the story of the Washington and Braddock roads, through Great Meadows from the Potomac to the Ohio. As outlined in Volumes III and IV of this series, this national highway was the realization of the youth Washington's early dream--a dream that was, throughout his life, a dominant force.
