At this hour I used often, after returning from a party, such as is described above, to put on my morning-gown and slippers, and light my pipe, then sallying forth, have strolled from Fuller's to the Capitol; and climbing its bold hill, have looked down along the sleeping city, speculating upon its possible destinies until my fancies waxed threadbare, and then quietly returned, making a distance of nearly three miles, without encountering an individual or hearing the sound of a human voice. At set balls even, the first hour of morning generally sees ample space on the, till then, crowded floor; and the most ardent pleasure-lovers rarely overleap the second by many minutes. The consequence of this excellent plan is, that, although the ladies are weak in numbers, they are always, to use an expressive sporting phrase, ready to come again; rising, the morning after a dance, unwearied and elastic in mind and body. I hope, for the sake of my American friends, it will be very long before these healthful hours are changed to those which custom has made fashionable in England; hours that soon fade the roses even on their most genial soil, the cheeks of the fair girls of Britain, blighting the healthful and the young, and withering the aged and the weak. Much of the population of Washington is migratory; and, during a long session, samples may be found here of all classes, from every part of the Union, whether represented or not. There are, however, generally resident a few old Southern families, who, together with the foreign ministers and their suites, form the nucleus of a permanent society, where the polish of Europe is grafted upon the simple and frank courtesy of the best of America. Were it not in violation of a rule I have imposed upon myself as imperative, I could name families here whose simple yet refined manners would do honour to any community, and from an intercourse with whom the most fastidious conventionalist would return satisfied. IMPRESSIONS OF ALEXANDRIA. A BLANK DAY. My worthy manager had often pressed me to accompany him on one of our off-nights to Alexandria, which he assured me boasted a very pretty theatre, and a population, if not generally theatrical, still capable of filling the house for two or three nights upon an extraordinary occasion. Such he was pleased to consider the present; and although I suggested the probability that most of the play-loving Alexandrians had most likely, during the late very lovely nights, visited the Washington theatre, Mr. Jefferson argued, there yet existed a sufficient body, of the unsatisfied curious, to repay us for our short trip. A steam-boat, he said, would take down him and his troop, bag and baggage, in a couple of hours; and, as I was fond of riding, it was for me but a pleasant canter.
