It seemed to me that he paled a bit at this, but I was too tired to gloat over a little thing like that, so I closed my eyes and went to sleep. A few days later I was so calm and rational that the doctor released me, and for the remainder of my voyage I was as free as any other person on board, except that I found myself constantly under surveillance, and was of course much irritated by the notion that my spacious stateroom was not only out of my reach, but probably in the undisputed possession of the cockney ghost. After seven days of ocean travel New York was reached, and I was allowed to step ashore without molestation. But my infernal friend turned up on the pier, and added injury to insult by declaring in my behalf certain dutiable articles in my trunks, thereby costing me some dollars which I should much rather have saved. Still, after the incidents of the voyage, I thought it well to say nothing, and accepted the hardships of the experience in the hope that in the far distant future my spook would meet his and thrash the very death out of him. Well, things went on. The cockney spook left me to my own devices until November, when I had occasion to lecture at a certain college in the Northwest. I travelled from my home to the distant platform, went upon it, was introduced by the proper functionary, and began my lecture. In the middle of the talk, who should appear in a vacant chair well down towards the stage but the cockney ghost, with a guffaw at a strong and not humorous point, which disconcerted me! I broke down and left the platform, and in the small room at the side encountered him. "Shove the fourth!" he cried, and vanished. It was then that I consulted Peters as to how best to be rid of him. "There is no use of talking about it," I said to Peters, "the man is ruining me. Socially with the Travises I am an outcast, and I have no doubt they will tell about it, and my ostracism will extend. On the _Digestic_ my sanity is seriously questioned, and now for the first time in my life, before some two thousand people, I break down in a public lecture which I have delivered dozens of times hitherto without a tremor. The thing cannot go on." "I should say not," Peters answered. "Maybe I can help you to get rid of him, but I'm not positive about it; my new scheme isn't as yet perfected. Have you tried the fire-extinguisher treatment?" I will say here, that Peters upon two occasions has completely annihilated unpleasant spectres by turning upon them the colorless and odorless liquids whose chemical action is such that fire cannot live in their presence. "Fire, the vital spark, is the essential element of all these chaps," said he, "and if you can turn the nozzle of your extinguisher on that spook your ghost simply goes out." "No, I haven't," I replied; "but I will the first chance I get." And I left him, hopeful if not confident of a successful exorcism.
