of children doing practical work in weaving which involved the use of the spinning wheel, worked out the diagrams of the direction of forces concerned in treadle and wheel, and the ratio of velocities between wheel and spindle. In the same manner, the plants with which the child has to do in cooking, afford the basis for a concrete interest in botany, and may be taken and studied by themselves. In a certain school in Boston science work for months was centered in the growth of the cotton plant, and yet something new was brought in every day. We hope to do similar work with all the types of plants that furnish materials for sewing and weaving. These examples will suggest, I hope, the relation which the laboratories bear to the rest of the school. The drawing and music, or the graphic and auditory arts, represent the culmination, the idealization, the highest point of refinement of all the work carried on. I think everybody who has not a purely literary view of the subject recognizes that genuine art grows out of the work of the artisan. The art of the Renaissance was great, because it grew out of the manual arts of life. It did not spring up in a separate atmosphere, however ideal, but carried on to their spiritual meaning processes found in homely and everyday forms of life. The school should observe this relationship. The merely artisan side is narrow, but the mere art, taken by itself, and grafted on from without, tends to become forced, empty, sentimental. I do not mean, of course, that all art work must be correlated in detail to the other work of the school, but simply that a spirit of union gives vitality to the art, and depth and richness to the other work. All art involves physical organs, the eye and hand, the ear and voice; and yet it is something more than the mere technical skill required by the organs of expression. It involves an idea, a thought, a spiritual rendering of things; and yet it is other than any number of ideas by themselves. It is a living union of thought and the instrument of expression. This union is symbolized by saying that in the ideal school the art work might be considered to be that of the shops, passed through the alembic of library and museum into action again.
