Thus runs the argument of the superstitious clergyman. And all the while, we may feel tolerably sure, little Miss Mompesson was chuckling inwardly at the panic into which she had thrown the reverend gentleman. * * * * * If it be objected that no girl of ten could successfully execute such a sustained imposture, one need only point to the many instances in which children of equally tender years or little older have since ventured on similar mystifications, with even more startling results. Incredible as it may seem to those who have not looked into the subject, it is a fact that there are boys and girls--especially girls--who take a morbid delight in playing pranks that will astound and perplex their elders. The mere suggestion that Satan or a discarnate spirit is at the bottom of the mischief will then act as a powerful stimulus to the elaboration of even more sensational performances, and the result, if detection does not soon occur, will be a full-fledged "poltergeist," as the crockery-breaking, furniture-throwing ghost is technically called. The singular affair of Hetty Wesley, which we shall take up next, is a case in point. So, too, is the history of the Fox sisters, who were extremely juvenile when they discovered the possibilities latent in the properly manipulated rap and knock. And the spirits who so maliciously disturbed the peace of good old Dr. Phelps in Stratford, Connecticut, a half century and more ago, unquestionably owed their being to the nimble wit and abnormal fancy of his two step-children, aged sixteen and eleven. It is to be remembered, further, that contemporary conditions were exceptionally favorable to the success of the Tedworth hoax. In all likelihood the children had nothing to do with the first alarm, the alarm that occurred during Mompesson's absence in London; and possibly the second was only a rude practical joke by some village lads who had heard of the first and wished to put the Squire's courage to a test. But once the little Mompessons learned, or suspected, that their father associated the noises with the vagrant drummer, a wide vista of enjoyment would open before their mischief-loving minds. Entering on a career of mystification, they would find the road made easy by the gullibility of those about them; and the chances are that had they been caught _in flagrante delicto_ they would have put in the plea that fraudulent mediums so frequently offer to-day--"An evil spirit took possession of me." As it was, the superstition of the times--and doubtless the rats and shaky timbers of Mompesson House did their part--was their constant and unfailing support. Everything that happened would be magnified and distorted by the witnesses, either at the moment or in retrospect, until in the end the Rev. Mr. Glanvill, recording honestly enough what he himself had seen, could find material for a history of the most marvelous marvels.
