As has been already stated, a short-story theme, however fine, can only be converted into good art by the suppression of whatever is discursive or ungainly, so that it becomes integral and balanced in all its parts; and by the addition of a stroke of fantasy, so that it becomes vast, despite its brevity, implying a wider horizon than it actually describes; but, in excess of these qualities, there is a last of still greater importance, without which it fails—the power to create the impression of having been possible.
