It was a most heavenly day in May of the year (1800) when I first beheld and first entered this mighty wilderness, the city--no, not the city, but the nation--of London. Often since then, at distances of two and three hundred miles or more from this colossal emporium of men, wealth, arts, and intellectual power, have I felt the sublime expression of her enormous magnitude in one simple form of ordinary occurrence, viz., in the vast droves of cattle, suppose upon the great north roads, all with their heads directed to London, and expounding the size of the attracting body, together with the force of its attractive power, by the never-ending succession of these droves, and the remoteness from the capital of the lines upon which they were moving. A suction so powerful, felt along radii so vast, and a consciousness, at the same time, that upon other radii still more vast, both by land and by sea, the same suction is operating, night and day, summer and winter, and hurrying forever into one centre the infinite means needed for her infinite purposes, and the endless tributes to the skill or to the luxury of her endless population, crowds the imagination with a pomp to which there is nothing corresponding upon this planet, either amongst the things that have been or the things that are. Or, if any exception there is, it must be sought in ancient Rome. [1] We, upon this occasion, were in an open carriage, and, chiefly (as I imagine) to avoid the dust, we approached London by rural lanes, where any such could be found, or, at least, along by-roads, quiet and shady, collateral to the main roads. In that mode of approach we missed some features of the sublimity belonging to any of the common approaches upon a main road; we missed the whirl and the uproar, the tumult and the agitation, which continually thicken and thicken throughout the last dozen miles before you reach the suburbs. Already at three stages' distance, (say 40 miles from London,) upon some of the greatest roads, the dim presentment of some vast capital reaches you obscurely and like a misgiving. This blind sympathy with a mighty but unseen object, some vast magnetic range of Alps, in your neighborhood, continues to increase you know not now. Arrived at the last station for changing horses, Barnet, suppose, on one of the north roads, or Hounslow on the western, you no longer think (as in all other places) of naming the next stage; nobody says, on pulling up, "Horses on to London"--that would sound ludicrous; one mighty idea broods over all minds, making it impossible to suppose any other destination. Launched upon this final stage, you soon begin to feel yourself entering the stream as it were of a Norwegian _maelstrom_; and the stream at length becomes the rush of a cataract. What is meant by the Latin word _trepidatio_? Not any thing peculiarly connected with panic; it belongs as much to the hurrying to and fro of a coming battle as of a coming
