176 LOCAL SCIENTIFIC SOCIETIES. principles of the science which he was studying : beginning with the practical experiments and observations, and working back to their interpretation. In a very short time he was able to publish important results. This is only one of several instances that I might quote from my own experience, but it is the most convincing. The interest and enthusiasm inspired by the feeling that one is making new observations, or in however humble a way working towards a discovery, is quite enough to inspire a long- ing to understand the general bearing of the work upon which one is engaged. This method would be impossible with a beginner of untrained mind ; but it is easy with a mature student who is a beginner only in the sense that he is not a specialist. Far too much time is often spent in preparation which leads to no per- formance ; and much harm is done by discouraging willing learners, because they have not been prepared in the orthodox manner. This is the reason why I see the opportunity for the Local Societies to take up the scientific education of unprepared but mature minds ; firstly, by inviting the trained and experienced workers to make known to them, through the medium of untechnical language, the beauty and interest of scientific work in the course of its progress, and of scientific discovery in the making ; and, secondly, by providing them with followers who will continue to prosecute under their guidance original observa- tion, and even experimental research. Everyone knows the success which has attended the University Extension movements, and how an inspiring lecturer has often sown the seed which has produced in literature, art, or science a rich harvest of sincere students. Let the Local Societies initiate a new Science Extension movement, in which they contribute from their members the willing workers who are ready to act under the guidance and inspiration of those who have had the advantage of special training and experience. Let them attract new members with this object. There are so many persons anxious and able to do something in the way of scientific work who only want the sympathy and guidance of a leader more experienced than them- selves; such leaders may not infrequently have to be sought among the teachers or researchers outside the society. In this way, and by some such co-operation, will the profes- sional cease to be a professional, and the amateur cease to be an amateur, when they meet upon common ground in the local scientific society. Surely anything that tends to break down the barrier between the professional scientist and the amateur, between expert and layman, is for the good of scientific progress ? That the one should ever be actually discouraged by the other seems almost incredible ; and yet one has to make the humiliating confession that this happens again and again.
