will learn his business, may be done without injury to his effect. He may not paint different pictures on the same canvas, which he will do if he allow himself to wander away to matters outside his own story; but by studying proportion in his work, he may teach himself so to tell his story that it shall naturally fall into the required length. Though his story should be all one, yet it may have many parts. Though the plot itself may require but few characters, it may be so enlarged as to find its full development in many. There may be subsidiary plots, which shall all tend to the elucidation of the main story, and which will take their places as part of one and the same work,--as there may be many figures on a canvas which shall not to the spectator seem to form themselves into separate pictures. There is no portion of a novelist's work in which this fault of episodes is so common as in the dialogue. It is so easy to make any two persons talk on any casual subject with which the writer presumes himself to be conversant! Literature, philosophy, politics, or sport, may thus be handled in a loosely discursive style; and the writer, while indulging himself and filling his pages, is apt to think that he is pleasing his reader. I think he can make no greater mistake. The dialogue is generally the most agreeable part of a novel; but it is only so as long as it tends in some way to the telling of the main story. It need not seem to be confined to that, but it should always have a tendency in that direction. The unconscious critical acumen of a reader is both just and severe. When a long dialogue on extraneous matter reaches his mind, he at once feels that he is being cheated into taking something which he did not bargain to accept when he took up that novel. He does not at that moment require politics or philosophy, but he wants his story. He will not perhaps be able to say in so many words that at some certain point the dialogue has deviated from the story; but when it does so he will feel it, and the feeling will be unpleasant. Let the intending novel-writer, if he doubt this, read one of Bulwer's novels,--in which there is very much to charm,--and then ask himself whether he has not been offended by devious conversations.
