Before Poe’s time the short story had sometimes been written well, and sometimes poorly. It had often been of too great length, wandering, and without point. Poe wrote stories that are different from many earlier stories in that they are all comparatively short. Another difference is that Poe’s stories do not wander, producing now one effect, and now another. Like a Roman road, every one goes straight to the point that the maker had in mind at the beginning, and produces one single effect. In the older stories the writers often turned from the principal subject to introduce other matter. Poe excluded everything,—no matter how interesting,—that did not lead directly to the effect he wished to produce. The earlier stories often ended inconclusively. The reader felt that more might be said, or that some other ending might be possible. Poe tried to write so that the story should be absolutely complete, and its ending the one necessary ending, with no other ending even to be thought of. With it all, he tried to write so that,—no matter how improbable the story really might be,—it should, at least, seem entirely probable,—as real as though it had actually happened. In general, Poe’s definition of the short story still holds true. There are many kinds of stories to-day,—just as there are many kinds of engines,—but the great fundamental principles hold true in both. We may still define the modern short story as: 1. A narrative that is short enough to be read easily at a single sitting; 2. That is written to produce a single impression on the mind of the reader; 3. That excludes everything that does not lead to that single impression; 4. That is complete and final in itself; 5. That has every indication of reality. III THE FAMILY TREE OF THE SHORT STORY Everyone knows his father and mother. Very few, except those of noble descent, know even the names of their great-great grandparents. As if of the noblest, even of royal descent, the short story knows its family tree. Its ancestry, like that of the American people, goes back to Europe; draws strength from many races, and finally loses itself somewhere in the prehistoric East,—in ancient Greece, India, or Egypt.
