Concerning the composition of the bulletin, we may borrow the rules of pictorial composition and adapt them to bulletin purposes. According to John C. Van Dyke, "Pictorial composition may be defined as the proportionate arranging and unifying of the different features and objects of a picture.... There must be an exercise of judgment on the part of the artist as to fitness and position, as to harmony of relation, proportion, color, light; and there must be a skilful uniting of all the parts into one perfect whole." In a bulletin as in a picture there must be a center of interest. We should strive to effect this by selecting for this purpose a picture which has earned its place, because it best suggests the subject, or because pictorially, either through tone or color, it best adapts itself to the principles of composition. The other pictures should be grouped accordingly, always taking account of the subject and artistic value of each in placing them. The bulletin should be built up architecturally as well, letting the heavy pieces support the light. Such a picture as Rosa Bonheur's "Ploughing" should not surmount Breton's "Song of the lark." Color has its legitimate place in bulletin work as children are keenly alive to its attractiveness. It is because they are so sensitive and impressionable in this regard that our responsibility is proportionately greater; this alone should make us most discreet and careful in its use. Van Dyke cautions us in the following terms: "Beware of your natural taste, beware of bright pictures for they are generally bad." He tells us "That 'color' does not mean brightness alone; and that a 'colorist' is not one who deals in flaming colors with the recklessness of a crazy-quilt maker, but one who justly regards the relationship, the qualities, and the suitableness of his colors one to another...." Harmony strives to associate colors which are congenial to each other; however, it cannot be comprehended in the abstract. We bring to our bulletin work the results of our previous standards of taste, be these high or low. But we may raise our standards by holding ourselves receptive to the influence of art, whether it be decorative, ceramic, textile, or pictorial, and appropriate the lessons which it teaches in blending color into harmony. The love of prime colors is characteristic of primitive man, while the appreciation of the neutral tones is the acquirement of civilization. Intellectual development conforms to the epochs of racial progress. Children love crude and elementary colors. But while we make concession to their taste we should also educate it to an appreciation of the refined in color.
