If I had not taken so much time in my other illustrations, I should like to show how, beginning with very simple material things, the children were led on to larger fields of investigation, and to the intellectual discipline that is the accompaniment of such research. I will simply mention the experiment in which the work began. It consisted in making precipitated chalk, used for polishing metals. The children, with simple apparatus—a tumbler, lime water, and a glass tube—precipitated the calcium carbonate out of the water; and from this beginning went on to a study of the processes by which rocks of various sorts, igneous, sedimentary, etc., had been formed on the surface of the earth and the places they occupy; then to points in the geography of the United States, Hawaii, and Puerto Rico; to the effects of these various bodies of rock, in their various configurations, upon the human occupations; so that this geological record finally rounded itself out into the life of man at the present time. The children saw and felt the connection between these geologic processes taking place ages and ages ago, and the physical conditions determining the industrial occupations of today. Of all the possibilities involved in the subject, “The School and the Life of the Child,” I have selected but one, because I have found that that one gives people more difficulty, is more of a stumbling-block, than any other. One may be ready to admit that it would be most desirable for the school to be a place in which the child should really live, and get a life-experience in which he should delight and find meaning for its own sake. But then we hear this inquiry: how, upon this basis, shall the child get the needed information; how shall he undergo the required discipline? Yes, it has come to this, that with many, if not most, people the normal processes of life appear to be incompatible with getting information and discipline. So I have tried to indicate, in a highly general and inadequate way (for only the school itself, in its daily operation, could give a detailed and worthy representation), how the problem works itself out—how it is possible to lay hold upon the rudimentary instincts of human nature, and, by supplying a proper medium, so control their expression as not only to facilitate and enrich the growth of the individual child, but also to supply the results, and far more, of technical information and discipline that have been the ideals of education in the past.
