If we could only get used to the idea that ghosts are perfectly harmless creatures, who are powerless to affect our well-being unless we assist them by giving way to our fears, we should enjoy the supernatural exceedingly, it seems to me. Coleridge, I think it was, was once asked by a lady if he believed in ghosts, and he replied, "No, madame; I have seen too many of them." Which is my case exactly. I have seen so many horrid visitants from other worlds that they hardly affect me at all, so far as the mere inspiration of terror is concerned. On the other hand, they interest me hugely; and while I must admit that I do experience all the purely physical sensations that come from horrific encounters of this nature, I can truly add in my own behalf that mentally I can rise above the physical impulse to run away, and, invariably standing my ground, I have gained much useful information concerning them.
