It is as bad as mixing metaphors to mingle physical and mental characteristics. In a description of the volcano of Kilauea I found this sentence:—
The combination of vivid red and green contrasted with the deathlike quiet and grandeur of the crater.
It is not possible to contrast physical qualities like color with emotional ones such as quiet and grandeur. It is like multiplying pictures by potatoes.
Of effects used in Description the appeal to the sight is manifestly by far the most effective. Indeed, it is to be questioned whether any other is of use save in very rare instances. Of course the individual temperament of the reader has much to do with this matter, and I am perhaps influenced by the fact that while it is very easy for me to see things in imagination it is rather difficult for me to hear them. There is no question, however, that an appeal to the sense of hearing is with the average reader less likely to be convincing than that to sight. It seems to me also that the use of smell is less often successful than either of the others, and yet Kipling has shown how effective this may be if employed by a master. The mention of odors is more likely, perhaps, to belong to description by suggestion than to description simple and direct.
An important element in Description is movement. This consists in showing the details of a picture as if the mind of the reader were moving from one to another. It is secured by naming them as they would be observed; by presenting them as they would successively become apparent to some other person; or by exhibiting them in connection with their effects. Perhaps I may be able to show this by three brief pictures of a peasant girl.
1. She was a beautiful peasant girl, tall and slender, dressed in the fashion of the country, and carrying in her hand a bunch of scarlet poppies. Her snowy coif was pushed back, showing brown cheeks, a mass of black hair, and bright, startled eyes.
2. Paul watched the tall, slender peasant come up the flowery lane, twirling in her hand as she walked a handful of flaming red poppies. He was sure that she had not noticed him, and he smiled at the unconscious beauty of her brown face, clear eyes, and black, wavy hair.
3. The artist’s gaze was suddenly arrested by a tall peasant girl, who walked slowly up the lane. He stopped to watch her, attracted by the grace of her slender figure, and noting appreciatively the effect against her gray gown of the scarlet poppies which she was twirling in her brown hands. As she drew nearer, and unconsciously pushed back the snowy coif, an involuntary exclamation escaped his lips at the brilliancy of the eyes which flashed out at him from beneath her black, tumbled hair.
Such movement as there is in the first of these depends upon the arrangement of the particulars in the order in which they would naturally be perceived by the reader; in the second this order is shown to be natural by presentation of the details as if they were seen by a spectator; while in the third the effect is heightened by the introduction of the emotions aroused in the mind of the artist by the sight of the girl. Whether these examples make the fact clear or not, there is no question that the last form is the most effective. It is not always available, nor is it always appropriate; but when it is possible it is more vivid and persuasive than any other method. There is in it more suggestiveness, and hence there is more force.
