"Teaching, not telling." (4) A fourth point I ought to mention is the danger of clinging too closely to the book habit; this I have already touched on. We are gradually growing out of the book slavery, even in arithmetic and grammar and history. This means a distinct advance in the abilities of the teacher. Of all subjects that should not be taught by the book, nature-study is chief. Its very essence is freedom from tradition and "method." I wish that there were more nature-study books; but they are most useful as sources of fact and inspiration, not as class texts. The good teacher of nature-study must greatly modify the old idea of "recitations." I wish to quote again from President Eliot: "Arithmetic is a very cheap subject to teach; so are spelling and the old-fashioned geography. As to teaching history in the old-fashioned way, anybody could do that who could hear a lesson recited. To teach nature-studies, geometry, literature, physiography, and the modern sort of history requires well-informed and skillful teachers, and these cost more than the lesson-hearers did." (5) Finally, we must come into contact with the actual things, not with museums and collections. Museums are little better than books unless they are regarded as secondary means. The museum has now become a laboratory. The living museum must come more and more into vogue,--living birds, living plants, living insects. The ideal laboratory is the out-of-doors itself; but for practical school purposes this must be supplemented. The most workable living laboratory of any dimensions is the school garden. The true school garden is a laboratory plat; time is coming when such a laboratory will be as much a part of a good school equipment as blackboards and charts and books now are. It will be like an additional room to the school building. Aside from the real school garden, every school premises should be embellished and improved as a matter of neighborhood and civic pride; for one cannot expect the child to rise above the conditions in which he is placed. All these dangers cannot be overcome by any "system" or "method;" they must be solved one by one, place by place, each teacher for himself. Whenever nature-study comes to be rigidly graded and dressed and ordered, the breath of life will be crushed from it. It is significant that everywhere mere "method" is giving way to individualism. In time, the methods of teaching nature-study will crystallize and consolidate around a few central points. The movement itself is well under way. It will persist because it is vital and fundamental. It will add new value and significance to all the accustomed work of the schools; for it is not revolutionary, but evolutionary. It stands for naturalness, resourcefulness, and for quickened interest in the common and essential things of life. We talk much about the ideals of education; but the true philosophy of life is to idealize everything with which we have to do. LEAFLET III.
