Brander Matthews has several stories of humorous supernaturalism, _Rival Ghosts_ being the account of ancestral spooks belonging to a young bridegroom, and who resent being brought into enforced companionship by his sudden elevation to a title, since one ghost must haunt the house and one the heir. The ingenious groom, at last harassed to invention by the continual squabbling of the ghosts, brings about a wedding between them. This is the only instance I have found of a wedding between two specters, though there are various cases on record of marriage between one living and one spectral personage. John Kendrick Bangs devotes several volumes to the doings and sayings of spooks, describing parties in a house-boat on the Styx, where the shades of the departed great gather together and engage in festivities and discussions, and showing types of water-ghosts and various kinds of spooks. The humorous ghost is a more frequent person than one would suppose without giving some thought to the subject, for many writers have sharpened their wits on the comic haunt. As may be seen from the examples mentioned, the ghost has made perceptible progress in psychology. The modern apparition is much more complex in personality than the crude early type, and shows much more variety. The up-to-date spook who has a chance to talk things over with William James, and knows the labyrinths of the human mind is much better adapted to inflict psychal terrors than the illiterate specter of the past. He can evolve mental tortures more subtle and varied than ever, or he can amuse a downcast mortal by his gambols. * * * * *
