For instance, a child in the nursery has littered the floor with its toys, and after finishing its play refuses to put them away. When next the child asks for its toy box the reply of its mother should be: "The last time you had your toys you left them lying on the floor and Jane had to pick them up. Jane is too busy to pick up every time the things you leave about, and I cannot do it myself, so that, as you will not put away your toys when you have done with them, I cannot let you have them." This is obviously a natural consequence and must be so recognized by the child. Or a little girl, Constance by name, is scarcely ever ready in time for the daily walk. The governess and the other children are almost invariably compelled to wait. In the world the penalty of being behind time is the loss of some advantage that one would otherwise have gained. The train is gone, or the steamboat is just leaving its moorings, or the good seats in the concert room are filled; and every one may see that it is the prospective deprivation entailed by being late which prevents people from being unpunctual. Should not this prospective deprivation control the child's conduct also? If Constance is not ready at the appointed time the natural result should be that she is left behind and loses her walk. Or, again, a boy is in the habit of recklessly soiling and tearing his clothes. He should be compelled to clean them and to mend the tear as well as he can. And if having no decent clothes to wear, the boy is ever prevented from joining the rest of the family on a holiday excursion and the like, it is manifest that he will keenly feel the punishment and perceive that his own carelessness is the cause of it. But I think it can easily be made clear that this method of moral discipline should be an exceptional and not a general one, and that there are not a few but many occasions when it becomes simply impossible to visit upon children the natural penalties of their transgressions. In these cases the evil consequences are too great or too remote for us to allow the child to learn from experience. A boy is leaning too far out of the window; shall we let him take the natural penalty of his folly? The natural penalty would be to fall and break his neck. Or a child is about to rush from a heated room into the cold street with insufficient covering; shall we let the child take the natural penalty of its heedlessness? The natural penalty might be an attack of pneumonia. Or, again, in certain parts of the country it is imprudent to be out on the water after nightfall owing to the danger of malaria. A boy who is fond of rowing insists upon going out in his boat after dark; shall we allow him to learn by experience the evil consequences of his act and gain wisdom by suffering the natural penalty? The natural penalty might be that he would come home in a violent fever.
