return of the metropolitan police for 1857, was 2825 brothels, and 8600 prostitutes. In the City, the number of such houses and persons is very small; the prison population at any particular time is 6000, costing for the year £170,000. Our juvenile thieves cost us £300 a-piece. The average income of the London thief is estimated at £2 per week. Again, let us look at the classes whose labours and occupations and modes of life are inconsistent with health, or not favourable to any great development of moral principle. Almost 20,000 persons are engaged in Sunday trading; the number of ragged children is nearly 30,000, the number of families living in one room is estimated as high as 150,000. It appears from a report by Mr. Goderich, officer of health in the parish of Kensington, that in a place called the Potteries there are 1147 human beings and 1041 pigs congregated within a space of less than nine acres, the present number of pigs being below the usual average. The dwellings of a large proportion of the inhabitants of this locality are mere hovels with shattered roofs and unglazed windows, the floor is below the level of the external soil, which has been raised by excessive accumulations of filth of all kinds, and the walls are at all times partially damp and giving out pestilential gases, intolerable to those who have not been born among them, fatal to the health of those who have. Another portion of the miserable population has converted old caravan bodies, removed in some cases from their wheels, into houses; others have no other dwelling than ruinous post-chaise bodies, for which a rent of sixpence per week is paid. In one of the caravans eight persons dwell, among whom a child suffering from small-pox was battling with death at the time of Mr. Goderich’s visit in March. Mr. Timbs calculates the number of professional beggars in London at 15,000, two-thirds of whom are Irish. 30,000 men, women, and children are employed in the costermonger trade; besides, we have, according to Mr. Mayhew, 2000 street sellers of green stuff, 4000 street sellers of eatables and drinkables, 1000 street sellers of stationery, 4000 street sellers of other articles, whose receipts are three millions sterling, and whose incomes may be put down at one. Let us extend our survey, and we shall not wonder that the public-houses—and the gin palaces—and the casinos—and the theatres—and the penny gaffs—and the lowest and vilest places of resort in London, are full. In Spitalfields there are 70,000 weavers with but 10_s._ per week; there are 22,479 tailors, 30,805 shoemakers, 43,928 milliners; seamstresses, 21,210; bonnet-makers, 1769; cap-makers, 1277. What hard, wretched work is theirs!
