Because Baltimore was built, like Rome, on seven hills, and because trains run under it instead of through, the passing traveler sees but little of the city, his view from the train window being restricted first to a suburban district, then to a black tunnel, then to a glimpse upward from the railway cut, in which the station stands. These facts, I think, combine to leave upon his mind an impression which, if not actually unfavorable, is at least negative; for certainly he has obtained no just idea of the metropolis of Maryland. Let it be declared at the outset, then, that Baltimore is not in any sense to be regarded as a suburb of Washington. Indeed, considering the two merely as cities situated side by side, and eliminating the highly specialized features of Washington, Baltimore becomes, according to the standards by which American cities are usually compared, the more important city of the two, being greater both in population and in commerce. In this aspect Baltimore may, perhaps, be pictured as the commercial half of Washington. And while Washington, as capital of the United States, has certain physical and cosmopolitan advantages, not only over Baltimore, but over every other city on this continent, it must not be forgotten that, upon the other hand, every other city has one vast advantage over Washington, namely, a comparative freedom from politicians. To be sure, Congress did once move over to Baltimore and sit there for several weeks, but that was in 1776, when the British approached the Delaware in the days before the pork barrel was invented. As a city Baltimore has marked characteristics. Though south of Mason and Dixon's Line, and though sometimes referred to as the "metropolis of the South" (as is New Orleans also), it is in character neither a city entirely northern nor entirely southern, but one which partakes of the qualities of both; where, in the words of Sidney Lanier, "the climates meet," and where northern and southern thought and custom meet, as well. This has long been the case. Thus, although slaves were held in Baltimore before the Civil War, a strong abolitionist society was formed there during Washington's first Administration, and the sentiment of the city was thereafter divided on the slavery question. Thus also, while the two candidates of the divided Democratic party who ran against Lincoln for the presidency in 1860 were nominated at Baltimore, Lincoln himself was nominated there by the Union-Republican party in 1864.
