From southeastern Maine to Boston, Providence, New Haven, New York City, and on to Baltimore, with a Western extension to Pittsburg, this irregular, now widening, now contracting, strip of country extended. It embraced the strategic positions, the falls of the rivers, the places whence ships could sail laden with the products of the industries or return with the raw materials necessary to their operation; it included the old commercial towns where the surplus capital of the East had been collected and where now gathered the populations which composed the districts whose spokesmen exerted the real strength of the North in the National Congress. It was this articulate East, the growing power of industry and finance, the promise of greater prosperity to come, which drew to it, like iron filings to a magnet, the talented and the ambitious men of the time, just as the black belt was the articulate part of the South for which men of ability and influence spoke in the national assemblies which gathered from year to year in Washington. But the older mercantile and seafaring interests sometimes resisted the industrial movement and made precarious alliances with the South on the basis of a national free-trade policy. The great Boston merchants actually turned to Hayne, of South Carolina, in 1827, to represent them and their cause in Congress. The Winslows, Goddards, and Lees who thus appealed to a Southern Senator were representatives of the older order, of the same declining class in New York and Philadelphia which had in years past controlled affairs in the East and made alliances with the aristocratic leaders of the South. In a hopeless minority in their own States before 1830, they looked to the South for relief, and at least understood the politics of the planters. Their successors composed the nucleus of the party of Cushing, Everett, and Winthrop in 1860. It is difficult for us in our day of great things to understand the industrial and social revolution of the decade which preceded the inauguration of the first Western President, and it was difficult for men to make the transition from the small farmer system of Jefferson's day to the industrial regime of 1830; many good people were broken in the process, while whole classes of the population exchanged the life of the open country for that of the crowded and unsanitary towns, exchanged a rude and hard independence for a semi-servile subjection.
