That this age is superstitious with regard to ghosts, is not wonderful; all ages have been so; the wonder is that this age should be so and yet be the possessor of a scientific record so extraordinary as its own. An age which has brought forth the magnetic telegraph, steamships and railway engines, sewing-machines, mowing-machines, gas-light, and innumerable discoveries and inventions of marvellous utility--not to allude to those of our own decade--should have no other use for ghostology than a scientific one. But it would be a work as idle as that of the Coblynau themselves, to point out how universal among the most civilised nations is the superstition that spirits walk. The 'controls' of the modern spiritualistic seance have the world for their audience. The United States, a land generally deemed--at least by its inhabitants--to be the most advanced in these directions of any on God's footstool, gave birth to modern spiritualism. Its disciples there compose a vast body of people, respectable and worthy people in the main (as the victims of superstition usually are), among whom are many men of high intellectual ability. With the masses, some degree of belief in the spirits is so nearly universal that I need hardly qualify the adjective. In a country where there is practically no such class as that represented in Europe by the peasantry, the rampancy of such a belief is a phenomenon deserving close and curious study. The present work affords no scope for this study, of course. But I may here mention in further illustration of my immediate theme, the constant appearance, in American communities, of ghosts of the old-fashioned sort. Especially in the New England states, which are notable for their enlightenment, are ghost-stories still frequent--such as that of the haunted school-house at Newburyport, Mass., where a disembodied spirit related its own murder; of the ghost of New Bedford, which struck a visitor in the face, so that he yet bears the marks of the blow; of the haunted house at Cambridge, in the classic shadow of Harvard College. It is actually on record in the last-named case, that the house fell to decay on account of its ghastly reputation, as no one would live in it; that a tenant who ventured to occupy it in 1877 was disturbed by the spirit of a murdered girl who said her mortal bones were buried in his cellar; and that a party of men actually dug all night in that cellar in search of those bones, while the ghost waltzed in a chamber overhead. The more common form of spirit peculiar to our time appears constantly in various parts of the country; it is continually turning up in the American newspapers, rapping on walls, throwing stones, tipping over tables, etc. 'Mediums' of every grade of shrewdness and stupidity, and widely differing degrees of education and ignorance, flourish abundantly. Occasionally, where revelations of murder have been made to a mortal by a spirit, the police have taken the matter in hand.
