This latter is one of the principal thoroughfares of the city, and had been very much crowded during the whole day. But, as the darkness came on, the throng momently increased; and, by the time the lamps were well lighted, two dense and continuous tides of population were rushing past the door. At this particular period of the evening I had never before been in a similar situation, and the tumultuous sea of human heads filled me, therefore, with a delicious novelty of emotion. I gave up, at length, all care of things within the hotel, and became absorbed in contemplation of the scene without. At first my observations took an abstract and generalizing turn. I looked at the passengers in masses, and thought of them in their aggregate relations. Soon, however, I descended to details, and regarded with minute interest the innumerable varieties of figure, dress, air, gait, visage, and expression of countenance. By far the greater number of those who went by had a satisfied business-like demeanor, and seemed to be thinking only of making their way through the press. Their brows were knit, and their eyes rolled quickly; when pushed against by fellow-wayfarers they evinced no symptom of impatience, but adjusted their clothes and hurried on. Others, still a numerous class, were restless in their movements, had flushed faces, and talked and gesticulated to themselves, as if feeling in solitude on account of the very denseness of the company around. When impeded in their progress, these people suddenly ceased muttering, but re-doubled their gesticulations, and awaited, with an absent and overdone smile upon the lips, the course of the persons impeding them. If jostled, they bowed profusely to the jostlers, and appeared overwhelmed with confusion.—There was nothing very distinctive about these two large classes beyond what I have noted. Their habiliments belonged to that order which is pointedly termed the decent. They were undoubtedly noblemen, merchants, attorneys, tradesmen, stock-jobbers—the Eupatrids and the common-places of society—men of leisure and men actively engaged in affairs of their own—conducting business upon their own responsibility. They did not greatly excite my attention.
