THEORY OF SPOTS
the principle that whatever is placed upon the surface made by four bounding lines or by the circle is a means of expression, and to so use this means that it will accomplish what we intend is to employ the art lan guage.
Let us analyze further. The eye is so created that it can focus upon only one spot at a time. For instance, if a boy is shown two apples of equal size, color, and shape, and is asked to choose, his eye will wander from one to the other. In the effort to see both he would have to look at a point between them; he would then be conscious of the one to the right and the other to the left, but he would not see them directly. So the mind when dealing with two spots alike in size does not linger on either, the attention is equally distributed, -Fig. 21. If, however, we make one large and the other small,-Fig. 22, the mind accepts the large one as a kind of accent or evidence of strength, and the smaller as an accessory, or if two small ones are grouped, - Fig. 23, they assume the relation to a third small one that the large spot held to the smaller, the mind going from the latter to the former. The same principle holds when a third, fourth, fifth or other spot is used, pro vided no other factor is called into play.
To make this applicable at once we will show three spots from a work arranged pictorially,-Fig. 24. The largest is composed of a well-lighted head, the second
