At 12 o'clock the night in the city may be said to begin. By that time the day toilers are at home, and the night shift is on. The street cars have ceased to run, and the last belated citizen, hurrying home from "the lodge" or the political caucus is, or should be, at home. Even the slow-moving couples who have been to the theater and partaken of oysters at the "cafe for ladies and gents," have bowed to the inevitable and reluctantly turned homeward. And now come forth things that flourish only in the shade; white-faced things with owl-like eyes who prowl in the night and greet the dawn with sullen faces and the sunlight with barred doors and darkened windows. Here and there down the streets are arc lights, and swinging doors, and about are grouped a pale and calm-faced gentry with immaculate clothes and white flexible hands. They are soft-voiced and courteous, but their eyes are shifty and their tread light and cruel as a tiger's. They are gamblers, and they will "rob" you as politely and honestly as any stock broker or railroad manipulator in Christendom. Byron says: "The devil's in the moon for mischief; not the longest day; The twenty-first of June sees half the mischief in a wicked way As does three hours on which the moonshine falls." And still worse; a night when there is no moon to shine. Darkness is the great awakener of latent passions and the chief inciter to evil. When night comes, the drunkard doubles his cups; the roisterer's voice is unrestrained; even the staid and sober citizen, the bulwark of civil and social government looses the checkrein of his demeanor and mingles in the relaxations of the social circle. The tongue of gallantry takes on new license, and even the brow and lip of innocence itself invite admiration with a bolder and a surer charm. What wonder, then, that lawlessness o'erreaches itself, and sin flaunts her flaming skirts in the very face of purity when darkness reigns! In the all-night saloons there is always someone to be found. At little tables in the corners one can always see two or three worn and shady-looking customers, sitting silent, brooding over the wrongs the world has dealt them, or talking in low, querulous tones to each other of their troubles. A smart policeman, with shining buttons and important step, goes down the street twirling his club. He tries the doors carefully of the big stores, the wholesale houses and the jewelry stores to see if they are securely locked. He never makes a mistake and wastes his time trying the fastenings of the small shops.
