Sincerely do I hope that the issue of this little book may prove useful in drawing the attention of the public to the mental and physical condition of the unfortunates who form such a large proportion of our prison population. To our authorities the sad plight of this mass of smitten humanity is well known. Year after year our Prison Commissioners, in presenting their reports, have not failed to impress upon the State the great part physical and mental afflictions play in the production of crime. So far, the information given by the Prison Commissioners has produced little or no effect; neither have their representations led to any alteration in the treatment of unfortunate individuals whose infirmities are in reality the root cause of their delinquency. To the official information I add the result of my own prolonged experience. This experience has imbued me with the conviction that the present methods of dealing with suffering humanity are neither wise, just, nor efficacious. I have seen the helplessness of so many that are called criminals that, in writing these pages, I am animated with a keen desire to hasten the day of sensible reform.
