To illustrate vividly the condition of the juvenile criminal, the bearing the law has upon his career and ultimate destiny, and, finally, to render intelligible the best remedies it is in the power of the country to apply to this worst of social diseases, it is only necessary to trace the private history of at least one-half of the unfortunate young beings who now infest our streets. Before us lie two documents, from which it is easy to glean the birth and parentage of a vast number of these wretched young creatures. The first is the Report of the Parkhurst Prison, and the second that of the Philanthropic Institution for the Reformation of Juvenile Offenders; both for the year 1848. Against the lists of 'admissions' into the latter establishment are placed short notes of the antecedents of the boys admitted during the year. The most frequently-recurring entries against the initials of those inmates who have been convicted more than once are such as:--'Father dead; mother remarried; deserted by his friends.' 'Turned out of doors by a stepfather.' 'Illegitimate; father unknown.' 'Father of dissolute habits; deserted his wife.' 'An orphan, both parents dead;' or 'Parents unknown,' occurs frequently. 'Mother dead, father remarried, and turned out of doors,' and 'Utterly friendless,' are also repeated in several instances. 'Mother separated from her husband: she is of drunken habits: the boy led into evil by discomforts of home:' 'Father of drunken habits,' are occasional entries. Those boys who were admitted into the school upon one conviction only, seem, in a majority of instances, to have been led away by evil companions. We select the following from this category as examples:--'The parents poor; father in bad health.' 'Father dead; mother respectable.' 'Enticed to theft by bad companions,' &c.
