The age in our history to which our attention is turned on this subject is more particularly that lying between the beginning of the second and the ending of the third decade of last century. Much that was proposed before the opening of the nineteenth century, in the way of material national advance, was forgotten in the taxing days of 1811-1815. Chief among these was the Erie Canal proposition, and it is perhaps not too much to say that had the war with England not come as it did, possibly the Government would, by means of the money accruing from the sale of Michigan lands, have invested in the Erie Canal project; the Cumberland Road was one of the great works that went on despite the war. The moral effect of the victories of Perry and Jackson, one to the north and the other to the south, was very great; with the triumphant ending of the war the little victorious nation sprang into a strength and a passion for power that well-nigh frightened those acquainted with the policy and conservatism of the ante-bellum days. We have touched slightly on one of the great questions of this most wonderful period of American history, that of the constitutionality of the appropriations for the Cumberland Road, and Henry Clay's championship of the measure. But this was only one of a score of propositions in a campaign of internal improvements, and Clay was but one of a hundred champions who assisted a weak nation to take on the elements of strength by encouraging agriculture and manufactures, and binding a far-flung land by means of communication and intercourse. [Illustration: PRESIDENT JAMES K. POLK] At the beginning of the second generation in the century the problem of internal improvements came to the fore as on no previous occasion, backed by the strongest men then in the public eye,--Clay, Calhoun, Adams, and Webster. The Cumberland Road had been making its way westward, but had not yet thrown its tawny length over the Ohio River and into the States beyond. But the argument for this great national work was not to be gainsaid, for the original compact with Ohio had been reiterated on the admission of Indiana, Illinois, and Missouri, respectively, and a part of the sales of the public lands in those States was already pledged to this object. As one of the fruits of the much discussed "American System," championed by Henry Clay, the Cumberland Road was a popular success, though there was never a time when any measure concerning it could not secure a strong following in the House and the Senate.
