Space does not allow the reproduction of the much that has been said and could be said of this work which, as I have tried to show, is not my work but the work of the "boys" themselves, the result of earnest conquering lives. Undoubtedly the lesson which men in prison need to learn almost above any other is that of _self-mastery_. Many are there through lack of self-control: others have utterly weakened will and deadened conscience by yielding themselves slaves to strong drink and yet others have let go their hold on the reins because, having once failed, they have allowed the feeling that it is no use to try again to rob them of courage. Just on this point their League membership has proved invaluable. If the new leaf is ever to be turned over, it should certainly be in prison. In the early days of our work many men would say to me as also to my dear friend and fellow-worker, Mrs. McAlpin, "No, I cannot take my stand now. It is too hard here, but I am determined to do right the day of my discharge." More and more the "boys" are coming to see how disastrous is such a fallacy. The man who does not have the courage in prison lacks it as much in freedom, when faced with the decision between right and wrong. There are, moreover, so many pitfalls and temptations awaiting him, to say nothing of the hard, up-hill road abounding in disappointments which almost all have to tread, that if he be not well prepared, failure is almost inevitable. Before he knows it, even with the best of intentions in his heart, such a man will be swept aside and carried away back to the whirlpool of vice and crime, from which he will all too quickly, be cast again on to the rocks of wreck and ruin.
