It is premature to say much of an institution which has existed for so short a time; but if the principle on which it is founded be as correct and sound as it appears, it must prosper and do good. There is, however, one great practical difficulty, which can only be removed by legislative enactment: there is no power at present to _detain_ the children in the Asylum, or to force them to attend the schools to which they have been Bent. Such have been the rise and progress of the four industrial schools in Aberdeen, including, as one of them, the Child's Asylum. All the schools are on the most catholic basis, the only qualification for membership being a subscription of a few shillings a year; and the doors are open to all who require admission, without distinction of sect or party. The experience, then, of Aberdeen appears to demonstrate the possibility of reclaiming even the most abject and depraved of our juvenile population at a very moderate expense. The schools have been so long in operation, that, if there had been anything erroneous in the principles or the management of them, it must ere now have appeared; and if all the results have been encouraging, why should not the system be extended and established in other places? There is nothing in it which may not easily be copied in any town or village of our land where it is required. I cannot help adding to this account some directions, which a very experienced teacher in these schools gives to those who are desirous of undertaking this enterprise. "1. The school rooms and appurtenances ought to be of the plainest and most unpretending description. This is perfectly consistent with the most scrupulous cleanliness and complete ventilation. In like manner, the food should be wholesome, substantial, and abundant, but very plain--such as the boys or girls may soon be able to attain, or even surpass, by their own exertions after leaving school. "2. The teachers must ever be of the best description, patient and persevering, not easily discouraged, and thoroughly versed in whatever branch they may have to teach; and, above all things, they must be persons of solid and undoubted piety--for without this qualification, all others will, in the end, prove worthless and unavailing. "Throughout the day, the children must ever be kept in mind that, after all, religion is 'the one thing needful;' that the soul is of more value than the body. "3. _The schools must be kept of moderate size_: from their nature this is absolutely necessary. It is a task of the greatest difficulty to manage, in a satisfactory manner, a large school of children, even of the higher classes, with all the advantages of careful home-training and superintendence; but with industrial schools it is folly to attempt it.
