We understand that this wholesome law was put in active operation at once in the city of Boston and in the adjoining town of Roxbury, and that a faithful execution of it bids fair to correct the hideous public nuisance of truant children. We wish it were practicable to secure similar legislation in our city. No indolent, thoughtless farmer ever stood on the borders of his field, and witnessed the broad-cast dispersion of Canada thistle-down over every part of it, with more composure than our lawmakers and magistracy look upon the spread of juvenile corruption in Philadelphia. We say this not without a grateful sense of the late liberality of the legislature in granting $60,000 towards the erection of a new Refuge in Philadelphia; nor without a just appreciation of the results of the labours of that excellent institution; nor without taking into view the various agencies designed to accomplish similar objects. But upon the mass of juvenile waywardness and depravity, they seem scarcely to have made a perceptible impression. The accumulation of the material out of which convicts are made is not sensibly checked. The sources of this corruption have been laid open to view in the reports of our Houses of Refuge, our Magdalen Asylums and police reports, but they remain as numerous and as prolific as ever. Corrupt places of amusement are thronged by boys and girls. Our eligible schools are open to them in vain. The hawking of newspapers, occasional jobs at the steamboat wharves or depots and chance-errands in the market-place, afford them means of vicious indulgence; and the regular service of an apprenticeship to some useful business, with the wholesome restraints which were formerly involved in this relation, are too irksome for their impatient spirits. Boys and girls of twelve or fifteen years of age, in a majority of cases, choose their own pursuits, receive the whole or a part of their earnings, to be expended at their pleasure; and with these elements of independence it is not difficult to connect a contempt for all authority, parental and magisterial, and this soon breaks up the foundations of society. Then there is that still unabated nuisance of young girls going about with fruit and candy; and by their very manner of life exciting, if not soliciting heartless wretches to make them their frequent or future prey. Is our community doomed to stand quietly by and see these streams of social corruption rising and swelling? Is there no arm long enough and strong enough to reach the fountain and check, if not suppress, its issues? We have given so much space to this topic of the report, that we must be satisfied with but a brief notice of the rest.
