LOCAL SCIENTIFIC SOCIETIES. 175 Up to the present, however, I have left out of sight the really great educational advantage that science possesses over all other subjects, namely this: That science is not only talk and thought, but action ; that there is always ready to hand, not only something new to be described or narrated, but something new to be actually done by both teacher and pupil. Either some natural object or occurrence to be seen that has never been seen before, or some experiment to be made that has never been made before. It is this which fires the enthusiasm and stirs the imagination, and makes scientific research so enthralling ; and the educational work which the Local Societies can best perform, because they are dealing not with children but with men and women, is the encouragement and direction of original research. A good deal is already done by some of them ; but on the whole how little compared with what might be done by some co-operation between scientific workers and the societies, and some organisation of the societies themselves. Education requires teacher and pupil ; it would not be enough in general that the members of a society should be interested by the address of a specialist and then be left to their own devices to imitate his work and endeavour to research for themselves. This would only, in general, lead to discouragement if not to disaster. After he has stimulated their interest, they need his guidance and advice. Let him then address them, with the object not of advertising his own researches, but of enlisting the services of fellow-workers. I believe that many a scientific investigator could attract an army of willing workers through the Local Societies if he were given the opportunity of interesting them in his own researches, of suggesting to them lines of simple investigation which they could profitably pursue, and of continuing to guide them by advice and criticism. Some- thing of the sort is occasionally done in the study of the local flora and fauna. That it is not done more widely and in other branches of science is due to the prevalent and growing idea that none can take up any original work without the preliminary of an orthodox scientific training. This I believe to be a great mis- take when the teacher is concerned with intelligent people who are no longer children, and who come to him with the desire for work. In an address delivered this year to the Public School Science Masters' Association, I ventured to illustrate this aspect of education by relating my own experience with a young French- man whose previous training and previous work were in the subjects of philosophy and theology, but who desired to have some personal acquaintance with scientific work. I found it possible with him to begin at once with a definite problem of original scientific research (even in a highly specialised branch of science), and to make that the introduction to the general
