they were, the prefet seeing that the introduction of the new carts became “a motive to discontent and collision,” took upon himself to set aside the contract with the contractor, who, he states, received no other compensation for his losses than a permission which he could not use to collect the refuse during the day, and the chiffonniers continue to the present time in the exercise of their wretched vocation at the expense of the public health and cleanliness. The course of the present inquiry shows how strongly circumstances that are governable govern the habits of the population, and in some instances appear almost to breed the species of the population. Conceiving it probable that the amount of filth left by defective cleansing had its corresponding description of persons, I made inquiries of the Commissioners of Metropolitan Police. From returns which they obtained from their superintendents, it appears that of the class of bone-pickers, mud-rakers, people living on the produce of dungheaps in mews, courts, yards, and bye lanes insufficient cleansed, 598 are known to the police. From an observation of the proportion of filthy children and adults who appear amidst refuse whenever there are new buildings and an unusual quantity of rubbish, and from other circumstances, I believe that, were the refuse of houses daily cast into the streets in London in the same manner as at Paris, London would soon have as large and as dangerous a population of the chiffonnier class. I am informed by Sir Charles Shaw, the chief commissioner of police at Manchester, that there are 302 of them known within the police jurisdiction of that town also. He complains that they have heretofore been licensed in their occupation; that, the children are pilferers, and occupy the attention of the police, and furnish a large quota to the stock of juvenile delinquents and the population of the prisons. I am informed that in Bath there are about 100 of them known; and in other towns and places I have little doubt that they would be found in like proportions, which approach the proportions of the stated numbers of chiffonniers to the population of Paris. These degraded creatures are also found amongst the inmates of the workhouses, and the close identity of their habits with those of the chiffonniers of Paris afford a striking proof of the similarity of the population produced by similarity of circumstances. They are thus described to me by an eye-witness:—
