"I lay down for this purpose, but I soon heard certain extraordinary sounds that disturbed my repose. Chains were clanked, noises were made, and shrieks and groans were heard from various parts of the mansion. All of these I had expected. They did not frighten me much. A little while after, just as I was going to sleep again, a curious string of light burned around the room. It ran along on the walls in a zigzag line, about six feet high, entirely through the apartment. I did not smell anything bituminous or like sulphur. It flashed quicker than powder, and it did not smell like it. Thinks I: 'This looks pretty well, we will have some amusement now.' Then the jangling of bells, and clanking of chains, and flashes of light; then thumpings and knockings of all sorts came along, interspersed with shrieks and groans. I sat very quiet. I had two of Colt's best pistols in my pocket, and I thought I could shoot anything spiritual or material with these machines made in Connecticut. I took them out and laid them on the table. One of them suddenly disappeared! I did not like that, still my nerves were firm, for I knew it was all gammon. I took the other pistol in my hand and surveyed the room. Nobody was there; and, finally half suspicious that I had gone to sleep and had a dream, I woke up with a grasp on my hand which was holding the other pistol. This soon made me fully awake. "I tried to recover my balance, and at this moment the candle went out. I lit it with one of my lucifers. No person was visible, but the noises began again, and they were infernal. I then took one of my sperm candles out, and went to unlock the door. I attempted to take the key out of my pocket. It was not there! Suddenly the door opened, I saw a man or a somebody about the size of a man, standing straight in front of me. I pointed one of Colt's revolvers at his head, for I thought I saw something human about him; and I told him that whether he was ghost or spirit, goblin or robber, he had better stand steady, or I would blow his brains out, if he had any. And to make sure that he should not escape I got hold of his arm, and told him that if he was a ghost he would have a tolerably hard time of it, and that if he was a humbug I would let him off if he would tell me the whole story about the trick. "He saw that he was caught, and he earnestly begged me not to fire that American pistol at him. I did not; but I did not let go of him. I brought him into the library, and with pistol in hand I put him through a pretty close examination. He was clad in mailed armor, with breastplate and helmet, and a great sword, in the style of the Crusaders. He promised, on condition of saving his life, to give me an honest account of the facts.
