Can most travelers, I wonder, enjoy as I do a solitary walk, by night, through the mysterious streets of a strange city? Do they feel the same detached yet keen interest in unfamiliar highways, homes, and human beings, the same sense of being a wanderer from another world, a "messenger from Mars," a Harun-al-Rashid, or, if not one of these, an imaginative adventurer like Tartarin? Do they thrill at the sight of an ill-lighted street leading into a no-man's-land of menacing dark shadows; at the promise of a glowing window puncturing the blackness here or there; at the invitation of some open doorway behind which unilluminated blackness hangs, threatening and tempting? Do they rejoice in streets the names of which they have not heard before? Do they--as I do--delight in irregularity: in the curious forms of roofs and spires against the sky; in streets which run up hill or down; or which, instead of being straight, have jogs in them, or curves, or interesting intersections, at which other streets dart off from them obliquely, as though in a great hurry to get somewhere? Do they love to emerge from a street which is narrow, dim, and deserted, upon one which is wide, bright, and crowded; and do they also like to leave a brilliant street and dive into the darkness of some somber byway? Does a long row of lights lure them, block by block, toward distances unknown? Are they tempted by the unfamiliar signs on passing street cars? Do they yearn to board those cars and be transported by them into the mystic caverns of the night? And when they see strangers who are evidently going somewhere with some special purpose, do they wish to follow; to find out where these beings are going, and why? Do they wish to trail them, let the trail lead to a prize fight, to a church sociable, to a fire, to a fashionable ball, or to the ends of the world? For the traveler who does not know such sensations and such impulses as these--who has not at times indulged in the joy of yielding to an inclination of at least mildly fantastic character--I am profoundly sorry. The blind themselves are not so blind as those who, seeing with the physical eye, lack the eye of imagination. Residence streets like Chase and Biddle, in the blocks near where they cross Charles Street, midway on its course between the Union Station and Mount Vernon Place, are at night, even more than by day, full of the suggestion of comfortable and settled domesticity. Their brick houses, standing wall to wall and close to the sidewalk, speak of honorable age, and, in some cases of a fine and ancient dignity. One fancies that in many of these houses the best of old mahogany may be found, or, if not that, then at least the fairly old and quite creditable furniture of the period of the sleigh-back bed, the haircloth-covered rosewood sofa, and the tall, narrow mirror between the two front windows of the drawing room.
