It is in the term "nature lesson" that the root of the mischief lies: nature is not a lesson to the young child, it is an interest from which he seeks to gain more pleasure, by means of his own activity: plants encourage him to garden, animals stir his desire to watch, feed and protect; water, earth and fire arouse his craving to investigate and experiment: there is no motive for passive study at this juncture, and without a motive or purpose all study leads to nothing. Adults compare, and count the various parts of a living thing for purposes of classification connected with the subdivisions of life which we call botany and zoology; but such things are far removed from the young child's world--only gradually does it begin to dawn on him that there are interesting likenesses, and that in this world, as in his own, there are relationships; when he realises this, the time for a nature lesson has come. But much direct experience must come first. In setting out the furnishing of the school the need for this activity is implied. No school worthy of the name can do without a garden, any more than it can do without reading books, or blackboards, indeed the former need is greater: if it is possible, and possibilities gradually merge into acceptances, a pond should be in the middle of the garden, and trees should also be considered as part of the whole. It is not difficult for the ordinary person to make a pond, or even to begin a garden. In a school situated in S.E. London in the midst of rows of monotonous little houses, and close to a busy railway junction, a miracle was performed: the playground was not very large, and of the usual uncompromising concrete. The children, most of whose fathers worked on the railway, lived in the surrounding streets, and most of them had a back-yard of sorts; they had little or no idea of a garden. One of the teachers had, however, a vision which became a reality. She asked her children to help to make a garden, and for weeks every child brought from his back-yard his little paper bag of soil which was deposited over some clinkers that were spread out in a narrow border against the outside wall; in a few months there was a border of two yards in which flowers were planted: the caretaker, inspired by the sight, did his share of fixing a wooden strip as a kind of supporting border to the whole: in two years the garden had spread all round the outside wall of the playground, and belonged to several classes.
