HE course of color instruction suggested in the preceding pages is not arbitrarily divided into lessons or even years, because the conditions in the city and rural schools in the various states of this country are so varied that no uniform allotment or division of time can be suggested which will be satisfactory to all.
The number of hours that can be devoted to any subject must be determined by those who prepare the school programme and the progress must be more or less rapid, with instruction correspondingly superficial or complete at each stage, according to the time allowed, the preparation of the teacher and the natural ability of the pupils.
The teaching of color is usually classed with drawing because both relate directly to art, but inasmuch as color enters into our every day experiences so much more largely than the graphic arts there seems to be good reason for teaching it very fully where little attention is given to drawing.
Every competent teacher can and will become expert and even enthusiastic in teaching color, if she fully understands the system which it is the object of the foregoing pages to explain.
The following brief outline suggests the order in which the facts concerning color may be presented and the material which can be used in an elementary course, beginning with the first primary grade pupils, who for the most part have not had kindergarten training.
As a part of the material the Bradley Educational Colored Papers, cut to tablets each 1 x 2 inches, are prepared and put up in four small envelopes which are enclosed in one larger envelope. On the larger envelope these words are printed: "The Bradley Paper Tablets for Primary Color Education, Selections 1, 2, 3, 4 for Complete Course." The four small envelopes are labeled in this way: "Selection No. 1, eighteen pieces from Chart of Pure Spectrum Scales, the Normal Spectrum Colors." "Selection No. 2, forty pieces from Chart of Pure Spectrum Scales, Tint No. 1 and Shades No. 1, with White, Black and Neutral Grays." "Selection No. 3, forty-two pieces comprising complete Chart of Broken Spectrum Scales and Warm, Cool and Green Grays." "Selection No. 4, thirty-six pieces from Chart of Pure Spectrum Scales, Tints No. 2 and Shades No. 2."
The Solar Spectrum.
MATERIAL.
A Glass Prism, the cost of which need not exceed a few cents, as almost any lamp or gas pendent in the form of a prism will serve the purpose. By the use of such a prism a small spectrum can be shown on the wall of any schoolroom having a sunny exposure during any part of the day. This spectrum will make plain the fact that sunlight is composed of many colors.
