On the other hand, the repeaters do account for a considerable portion of the _cases_ before the courts, especially the municipal courts, because each offender appears time and time again. In the Virginia city cited, for example, repeaters furnished 60% of the jail commitments for three years. This is probably also an indication of the workhouse situation, which is best represented by such a study as that of Kohs. The proportions of _offenses_ accounted for by deficiency would, therefore, be much larger than the proportion of _offenders_ who are deficient. While the offenses of repeaters might not commonly be serious crimes, they afford a serious problem because of their bulk and because temporary restraint is of little use when the offender is mentally weak. As Aschaffenburg says: “We must not forget that it is not the murderers, not the swindlers, on a large scale, not the assassins of people in high places, and not the sexual murderers, that determine the criminal physiognomy of our day, but the thieves and pickpockets, the swindlers and abusers of children, the tramps and the prostitutes” (_68_, p. 181). The best that we can do is to study Table XI, which gives us a classified list of different types of delinquents in institutions. If we should pick out in it such institutions as represent to us the typical conditions in the country we could get an idea of what we might expect from groups of offenders of each type. For example, we might say that the Massachusetts State prison is typical of such institutions, and it contained possibly 16% who were deficient. Picking the Ohio Boys Industrial School as typical of its class, it had between 15% and 42% deficient, depending on how conservative you wish to be in your diagnosis. So one might go through the list stating the expectation for each type of institutional delinquent. If these were then weighted according to the number of delinquents of each class in the country sent to them, we would have some idea of the frequency of deficiency among those who reach the institutions. Merely to average the columns in Table XI would give only a false impression. The seriousness of the situation is amply demonstrated among repeaters and the inmates of certain institutions. Each superintendent should be put upon inquiry as to his own charges.
