After the age of manhood has been reached, and the main lines of character are formed, punitive methods of dealing with criminal offenders must assume a more prominent position, and the prison should then take the place of the Reformatory. In youth the deterrent effects of punishment are small, and the beneficial effects of reformative measures are at their maximum. In manhood, on the other hand, this condition of things is reversed, and the deterrent effects of punishment exceed the beneficial effects of reformative influences. An interesting example of the value of punishment for adults, as compared with other methods, is given by Sir John Strachey in his account of infanticide in certain parts of India. "For many years past," he says, "measures have been taken in the North-West Provinces for the prevention of this crime. For a long time, when our civilisation was less belligerent than it has since become, it was thought that the best hope of success lay in the removal of the causes which appeared to lead to its commission, and especially in the prevention of extravagant expenditure on marriages; but although these benevolent efforts were undoubtedly useful, their practical results were not great, and it gradually became clear that it was only by a stringent and organised system of coercion that these practices would ever be eradicated. In 1870 an act of the legislature was passed which enabled the Government to deal with the subject. A system of registration of births and deaths among the suspected classes was established, with constant inspection and enumeration of children; special police-officers were entertained at the cost of the guilty communities, and no efforts were spared to convince them that the Government had firmly resolved that it would put down these practices, and would treat the people who followed them as murderers. Although the time is, I fear, distant when preventive measures will cease to be necessary, much progress has been made, and there are now thousands of girls where formerly there were none. In the Mainpuri district, where, as I have said, there was not many years ago hardly a single Chauhan girl, nearly half of the Chauhan children at the present time are girls; and it is hoped that three-fourths of the villages have abandoned the practice."[32] [32] _India_ by Sir John Strachey, pp. 292-3.
