The title "Juvenile-Adult" was invented to describe the class--too old for commitment to Reformatory Schools, and too young to be classified with the ordinary grown-up criminal. The average number of youths of this age committed to Prisons in England and Wales in the opening years of this century was about 19,000. For one year their distribution was as follows:-- 16 years 2,898 17 " 4,099 18 " 5,550 19 " 5,576 20 " 5,130 Some light was thrown on the character and antecedents of this class of young criminal by an inquiry made with regard to the offences, previous convictions, homes, and educational status of all male prisoners in the Prisons of England and Wales, on a given day, within the ages of sixteen to twenty-one. The total number was 1,238. Nearly two-thirds were guilty of crimes of acquisitiveness, _i.e._, larceny, burglary, housebreaking, embezzlement, &c. One-fifth of crimes of passion, _i.e._, sexual offences, assaults, and wounding. There were twenty cases of malicious injury to property, and the remainder were convicted of minor offences against bye-laws, &c. With regard to their education, ninety had none, 512 little, 496 fair, and 111 good. Of the total number, 280 had good homes, but 198 had none at all; 138 had bad ones, and thirty lived in common lodging houses. Only 330 were without previous convictions and 353 had two or more. At the same time, Dr. Baker, of Pentonville Prison, conducted a most interesting inquiry with regard to the young offenders between sixteen and twenty, who passed through Pentonville Prison in the course of a year. The total was 2,185. Physically, as a class, they were two-and-a-half inches below the average height, and fourteen lbs. less than the average weight. Twenty-six per cent. were afflicted with bodily infirmity. The majority of the offences were of a grave character, offences against the person and against property without violence. Twenty-two per cent. were imprisoned for larceny alone, the various crimes of "acquisitiveness" being characteristic of this age; while in the aggregate _thirty-four_ per cent. had been previously convicted (no less than 144 on three or more occasions). In the case of offences against property, with and without violence, and vagrancy, the reconvictions were 50, 40, and 45 per cent. respectively. Public attention has also been called to the large number of indictable offences, and of larceny in particular, committed by persons of this age. Criminal statistics are dominated by the rise or fall in offences of larceny, and this age-category contributed nearly 30 per cent.
