 by pasting the eighteen paper samples, including standards and intermediate hues, in their order on a strip of paper, so that by bringing the ends together the children may see that when they place the violet-red at one end of their row and the red-violet at the other they are really completing a spectrum circuit and forming a chart of natural colors. Ever since Newton's day it has been fashionable to speak of the spectrum as nature's chart of colors. This expression is but partially true and is entirely false if we mean that it contains examples of all the colors in nature. The spectrum is valuable ill color study only from the fact that it enables us to establish permanent standard colors from which all colors in nature and the arts may be named and by the combinations of which such colors may be imitated.

Unless the standard colors in a system of color instruction are the closest possible imitations of corresponding spectrum colors there is no logical relation between such a system and a chart of colors based on the spectrum, because the spectrum does not furnish a complete circuit of colors and its only value is, as before stated, in furnishing a permanent standard on which to found a nomenclature of colors.

Up to this time we have not suggested the practice of introducing any natural objects or calling the attention of the children to various colors found in their surroundings. Each teacher must use her judgment regarding this matter, but as soon as miscellaneous colors are to be considered the two questions of hues and tones are necessarily involved, and experienced teachers have been divided in their opinions as to which should be first considered, tone or hue. When it was thought necessary to occupy a long time in presenting all the spectrum colors this question assumed greater importance than at present, but very many teachers have become convinced that we have not been giving the children credit for nearly as much ability in the recognition of colors as they deserve, and that with the methods at present in use the six standard colors and twelve hues can
