[I felt a great deal better after blowing off the ill-temper condensed in the above paragraph. To brag little,--to show well, --to crow gently, if in luck,--to pay up, to own up, and to shut up, if beaten, are the virtues of a sporting man, and I can't say that I think we have shown them in any great perfection of late.] --Apropos of horses. Do you know how important good jockeying is to authors? Judicious management; letting the public see your animal just enough, and not too much; holding him up hard when the market is too full of him; letting him out at just the right buying intervals; always gently feeling his mouth; never slacking and never jerking the rein;--this is what I mean by jockeying. --When an author has a number of books out a cunning hand will keep them all spinning, as Signor Blitz does his dinner-plates; fetching each one up, as it begins to "wabble," by an advertisement, a puff, or a quotation. --Whenever the extracts from a living writer begin to multiply fast in the papers, without obvious reason, there is a new book or a new edition coming. The extracts are GROUND-BAIT. --Literary life is fun of curious phenomena. I don't know that there is anything more noticeable than what we may call CONVENTIONAL REPUTATIONS. There is a tacit understanding in every community of men of letters that they will not disturb the popular fallacy respecting this or that electro-gilded celebrity. There are various reasons for this forbearance: one is old; one is rich; one is good-natured; one is such a favorite with the pit that it would not be safe to hiss him from the manager's box. The venerable augurs of the literary or scientific temple may smile faintly when one of the tribe is mentioned; but the farce is in general kept up as well as the Chinese comic scene of entreating and imploring a man to stay with you with the implied compact between you that he shall by no means think of doing it. A poor wretch he must be who would wantonly sit down on one of these bandbox reputations. A Prince-Rupert's-drop, which is a tear of unannealed glass, lasts indefinitely, if you keep it from meddling hands; but break its tail off, and it explodes and resolves itself into powder. These celebrities I speak of are the Prince-Rupert's drops of the learned and polite world. See how the papers treat them! What an array of pleasant kaleidoscopic phrases, which can be arranged in ever so many charming patterns, is at their service! How kind the "Critical Notices"--where small authorship comes to pick up chips of praise, fragrant, sugary, and sappy--always are to them! Well, life would be nothing without paper-credit and other fictions; so let them pass current. Don't steal their chips; don't puncture their swimming-bladders; don't come down on their pasteboard boxes; don't break the ends of their brittle and unstable reputations, you fellows who all feel sure that your names will be household words a thousand years from now.
