Boxing-day in the London streets, and especially a wet Boxing-day, can scarcely fail to afford us some tableaux vivants illustrative of English metropolitan life. In a metaphorical and technical sense, Boxing-day is always more or less "wet"--generally more, and not less; but this year the expression is used climatically, and in its first intention. Christmas-eve of the year about which I write was bright and springlike; Christmas-day dismal, dark, and un-Christmas-like; but Boxing-day that year was essentially muggy, sloppy, drizzly, and nasty. A day to avoid the London streets if you want to take a romantic Rosa-Matilda view of London life; but the very day of all others, if you wish to see real London as it is. Boxing-day will inevitably be "wetter" in every sense than usual this year, internally and externally. So let us commence our series of living pictures at ten o'clock in the morning. Suppose we begin with something that shall bear reference to the past festival--the eve and the day of the Great Birth, recollect. See, here is Grotto Passage, Marylebone, and at its extremity Paradise Street--the names sound promising, but alas for the reality! We are going to turn for a moment into the Marylebone Police Court, where Mr. D'Eyncourt is dispensing summary justice to the accumulations of the last two days. These are the people who have been spending Christmas-eve, Christmas-day, and some portion of Boxing-day already in the police-cells. Let us take one as a typical case. Let that poor little eight-year-old Arab step down from the dock and go off with his mother, who, we hope, will take the magistrate's excellent advice, and keep the child from begging--that is why he has spent Christmas in the cells--lest he be sent to a school for eight years, and she have to pay for him--God help her! she does not look as though she could afford very high terms. A bruised and bleeding woman, not young or good-looking, enters the box with her head bound up. Her lord and master confronts her in the dock. It is the "old, old story." A drop of drink yesterday--the day of the Great Nativity, never forget--series of "drops of drink" all day long; and, at five o'clock, just when gentility was beginning to think of dinner, the kitchen poker was used with frightful effect. A triangular cut over the right eye, and another in the dangerous neighbourhood of the left ear, administered with that symbol of domestic bliss, the kitchen poker, sends the wife doubled up into a corner, with an infant of two years old in her arms. The head of the family goes out for a walk after his exertions. The woman lies there bleeding until the neighbours hear her "mourning," as she terms it--the result being that the lord and master's "constitutional" is cut short by a policeman, and the happy pair are this morning separated for six months, at the expiration of which period Paterfamilias is to find surety for another six months' good behaviour.
