does gain, but not as fast as so intelligent a race should. In penology something has been learned. Here, dealing with the extreme criminal, we are slowly establishing the facts that arbitrary and severe punishment does not proportionately decrease crime; that crime has causes, which may be removed; and that the individual needs to be treated beforehand, preventively, rather than afterward, retributively. This would seem to throw some light on infant penology. If retributive punishment does not proportionately decrease crime in adult criminals, perhaps it does not decrease "naughtiness" among little children. If there is an arrangement of conditions and a treatment which may prevent the crime, perhaps there may be an arrangement of conditions and a treatment which will prevent the naughtiness.
