I did not trouble myself to examine them; it did not seem to me that the books would be of much service in my case; the facts themselves were sufficiently strong and stern, and I mentally scouted the idea that printed matter would enable me to get rid of the apparition that haunted me. "It is clear to me," I said, "that you think I am laboring under some hallucination, and that I see the specter, now lying on the hearthrug, with my mental and not my actual vision. Very well, Bob; a difference of opinion will not alter the facts." "The awkward part of it is," said Bob, "that all evidence is against you." I nodded toward the books on the table, and said, "All such evidence as that." "Yes, but you must not forget that cleverer heads than ours have occupied years of their lives in sifting these matters to the bottom." "In trying to sift them, Bob." "Well, in trying to sift them; but they give reasons for the conclusions they arrive at which it would be difficult, if not impossible, for men like ourselves to argue away." "There are two strong witnesses on my side," I remarked; "one is myself, the other is my wife. Bear in mind that we both saw the apparition of the girl; there was no collusion between us beforehand, and if, in our fright, our imaginations were already prepared to conjure up a phantom of the air, it is hardly possible that that phantom should, without previous concert, assume exactly the same form and shape; nor was there any after conspiracy between us as to the manner in which this phantom was to be dressed. Now, my wife has described to me the dress of the girl, the shreds of a cap sticking to her hair, the frock of faded pink, the carpet slippers, the black stockings, and I recognize the faithfulness of these details, which presented themselves to me exactly as they did to her. Granted that one mind may be laboring under a delusion, it is hardly possible that two minds can simultaneously be thus imposed upon. Answer that, Bob." "Sympathy," he replied. "The word I used yesterday evening, when I was imagining what the doctors would say upon my case; it is an easy way to get out of it, but it does not satisfy me. I suppose you have come across some curious cases in looking up apparitions?"
