Only those whose duties or whose studies bring them into contact with the saddest phase of child-life in London know how terrible is the picture that could be painted by an artist who, in his desire for realism, did not shrink from the most painful details. It is not my desire, nor is it the purpose of these chapters, to take the darkest view of the sins and sorrows of the City. The truth--the appalling truth--concerning the phase to which I am now referring is written in the records of the schools in which the feeble-minded children of London are specially cared for and dealt with. In these volumes the family history of the parents of every child is written, the doctor's view of the child's mental and physical condition is given, and nothing that can be ascertained for the guidance of the teachers is left unrecorded. The authorities have decided--and very wisely decided--that these volumes shall be bound with metal clasps and locked from the eyes of all save those who have by their official position the right of access to them. There are some terrible family histories in those guarded volumes. The sins of the parents are there, and the children on whom the sins have been visited are in the schools for the mentally and physically unfit. Not always is it sin that has set its mark upon the offspring. Drink has much to answer for in the deterioration of a race; but here there is affliction as well--degenerate parents have married and given the world degenerate children. Insanity, epilepsy, all the forms of mental instability contribute to the legion of the lost little ones. If you could see the record of the parents you would find again and again that suicide and insanity had occurred in the family. You would find weak-minded parents with six and seven children--sometimes with ten. Out of one family of ten that I know only two of the children are normal. Through the generations the taint has been handed down, and that is the reason that lunacy is advancing by leaps and bounds, and the number of the insane is now so great that even the unthinking are beginning to be alarmed. I am not going to point a moral here or to urge a reform. This is not the place. But I have been compelled to state the truth that the reason for the existence in our midst of a class of children who are dangerous to the community may be understood. Here is a lad of fifteen. A few months ago the law decided that the time had come when the freedom of the home and the streets shall be denied him, and that he shall be kept where the commission of further crimes by him will be guarded against. This lad of fifteen attempted to murder a little boy of six. He met the boy in the streets, took him to a lonely place, and there savagely attacked him. The child succeeded in escaping from the homicidal maniac of fifteen, who later on was arrested and charged at the police-court.
