Other types of clever pupils are those who are helped at home by tutors, or educated mothers who devote themselves to their advancement; while other types of dull pupils, often punished, are poor children who are not made welcome in their homes, but are left to themselves, sometimes in the streets; or who are already working for their bread in the early hours of the morning, before coming to school. In an inquiry I made, the children who were praised and passed without examination were in the category of those who brought a good luncheon with them; the children at the bottom of the class, who incurred punishments, were those who brought no provisions, or only a piece of bread. It must not be supposed that the above is an exhaustive enumeration of the causes which contribute to the deceptive phenomenon connected with prizes and punishments; but it is obvious that a clearly defined road has been marked out which should lead us to comprehension of the facts. Prizes and punishments are not merely final episodes, they are exponents of the moral organization of the school. Just as the annulment of the examination of a pupil who has helped a companion is but the extreme instance of "an education" which tends to isolate the individual in his egotism; so the prize and the punishment are the extreme incidents of the constant principle on which the organism of the school is based: emulation. The principle is that children, seeing others cleverer than themselves, who get high marks, praises and prizes, will be stimulated to imitate these, to do better, to overtake their companions. Thus what may be described as a kind of mechanism is evolved, which uplifts the whole school, not merely towards work, but towards effort. It is the moral purpose to accustom children to "suffer."
