The Mazengarb Committee was of opinion that there should be a long-term study of the problem of delinquency. As a matter of fact the present Committee heard evidence on this suggestion from several witnesses, and we were greatly impressed by what we heard. It goes without saying that if one would seek a remedy for a given problem a thorough diagnosis of the problem itself is a fundamental prerequisite. First let us find the facts; let us know what is the nature and extent of the evil; let us get as much data as to its causes and incidence. With that material in hand we should be in a better position to search for useful methods of treatment. This task of fact finding would be a long and arduous one; it would need to be entrusted to experts of wide knowledge and experience. A start has already been made by the setting up of the Inter-Departmental Committee referred to earlier in this report. We strongly recommend the Government to give very favourable consideration to this particular proposal, and we hope that ways and means will be found of giving effect to it. We think that this suggestion is of fundamental importance in any approach to the problem, and we consider it should be given consideration by the Government. _Instruction for Parents_: In the long run the responsibility for a child's general well-being rests upon the parents. Some can, and do, take every care to discharge that responsibility. Others either fail or neglect to do so. In some cases this failure comes from a lack of the necessary knowledge or from inability to impart it. In one memorandum addressed to the Committee there appear the following paragraphs: "I think it highly probable that much delinquency is due to the fact that parents simply do not know how to teach their children on a subject that many parents regard as secret between parents. I think it highly unlikely that a parent will consult an adviser (say, a doctor) as to how the child should be trained, and I am not so sure that a doctor would know what advice to tender even if he was consulted. "Instruction of parents seems to be the job of a specialist. The doctors have prepared several booklets on sex instruction. "I am wondering if good attendance could be secured for a series of lectures by specialists to parents, either to both sexes or to mothers alone. A mother would probably be more likely to attend a meeting as one of an audience rather than to suffer the embarrassment of a personal consultation with, say, a doctor to whom she has to admit that she does not know how to discharge her duty to her children.
