When description is intended solely to give accurate information—as to delineate the appearance, not the technical construction, of the latest Zeppelin airship—it is called "scientific description," and is akin to exposition. When it is intended to present a free picture for the purpose of making a vivid impression, it is called "artistic description." With both of these the public speaker has to deal, but more frequently with the latter form. Rhetoricians make still further distinctions.
Methods of Description
In public speaking, description should be mainly by suggestion, not only because suggestive description is so much more compact and time-saving but because it is so vivid. Suggestive expressions connote more than they literally say—they suggest ideas and pictures to the mind of the hearer which supplement the direct words of the speaker. When Dickens, in his "Christmas Carol," says: "In came Mrs. Fezziwig, one vast substantial smile," our minds complete the picture so deftly begun—a much more effective process than that of a minutely detailed description because it leaves a unified, vivid impression, and that is what we need. Here is a present-day bit of suggestion: "General Trinkle was a gnarly oak of a man—rough, solid, and safe; you always knew where to find him." Dickens presents Miss Peecher as: "A little pin-cushion, a little housewife, a little book, a little work-box, a little set of tables and weights and measures, and a little woman all in one." In his "Knickerbocker's" "History of New York," Irving portrays Wouter van Twiller as "a robustious beer-barrel, standing on skids."
Whatever forms of description you neglect, be sure to master the art of suggestion.
Description may be by simple hint. Lowell notes a happy instance of this sort of picturing by intimation when he says of Chaucer: "Sometimes he describes amply by the merest hint, as where the Friar, before setting himself down, drives away the cat. We know without need of more words that he has chosen the snuggest corner."
Description may depict a thing by its effects. "When the spectator's eye is dazzled, and he shades it," says Mozley in his "Essays," "we form the idea of a splendid object; when his face turns pale, of a horrible one; from his quick wonder and admiration we form the idea of great beauty; from his silent awe, of great majesty."
Brief description may be by epithet. "Blue-eyed," "white-armed," "laughter-loving," are now conventional compounds, but they were fresh enough when Homer first conjoined them. The centuries have not yet improved upon "Wheels round, brazen, eight-spoked," or "Shields smooth, beautiful, brazen, well-hammered." Observe the effective use of epithet in Will Levington Comfort's "The Fighting Death," when he speaks of soldiers in a Philippine skirmish as being "leeched against a rock."
Description uses figures of speech. Any advanced rhetoric will discuss their forms and give examples for guidance.[21] This matter is most important, be assured. A brilliant yet carefully restrained figurative style, a style marked by brief, pungent, witty, and humorous comparisons and characterizations, is a wonderful resource for all kinds of platform work.
Description may be direct. This statement is plain enough without exposition. Use your own judgment as to whether in picturing you had better proceed from a general view to the details, or first give the details and thus build up the general picture, but by all means BE BRIEF.
