"I grant," said I, "that these hieroglyphics might well puzzle a more practised decipherer than myself. Still, I can point out even here a clue which might help detection. There occur, even in these two lines, three or four symbols which, from their size and complication, are evidently abbreviations. Again, the distinct forms are very few, and have obviously been made to serve for different letters by some slight alterations devised upon a fixed rule. In a word, the cipher has been constructed upon a general principle; and though it may take a long time to find out what that principle is, it affords a clue which, carefully followed out, will probably lead to detection." "You have perceived," said Colonel A——, "a fact which it took me very long to discover. I have not deciphered all the more difficult passages of the manuscript from which I took this example; but I have ascertained the meaning of all its simple characters, and your inference is certainly correct." Here he stopped abruptly, as if he thought he had said too much, and the subject dropped. We reached New York early in the morning and separated, having arranged to visit that afternoon a celebrated "spiritual" medium who was then giving _séances_ in the Empire City, and of whom my friend had heard and repeated to me several more or less marvellous stories. Our visit, however, was unsatisfactory; and as we came away Colonel A—— said— "Well, I suppose this experience confirms you in your disbelief?" "No," said I. "My first visits have generally been failures, and I have more than once been told that my own temperament is most unfavourable to the success of a seance. Nevertheless, I have in some cases witnessed marvels perfectly inexplicable by known natural laws; and I have heard and read of others attested by evidence I certainly cannot consider inferior to my own." "Why," he said, "I thought from your conversation last night you were a complete disbeliever." "I believe," answered I, "in very little of what I have seen. But that little is quite sufficient to dispose of the theory of pure imposture. On the other hand, there is nothing spiritual and nothing very human in the pranks played by or in the presence of the mediums. They remind one more of the feats of traditionary goblins; mischievous, noisy, untrustworthy; insensible to ridicule, apparently delighting to make fools of men, and perfectly indifferent to having the tables turned upon themselves." "But do you believe in goblins?"
