"Then stand by to let her go." It was nine o'clock on a Wednesday morning. The good ship _Spartan_ was lying off Boston Quay with her cargo under hatches, her passengers shipped, and everything prepared for a start. The warning whistle had been sounded twice, the final bell had been rung. Her bowsprit was turned towards England, and the hiss of escaping steam showed that all was ready for her run of three thousand miles. She strained at the warps that held her like a greyhound at its leash. I have the misfortune to be a very nervous man. A sedentary literary life has helped to increase the morbid love of solitude which, even in my boyhood, was one of my distinguishing characteristics. As I stood upon the quarter-deck of the Transatlantic steamer, I bitterly cursed the necessity which drove me back to the land of my forefathers. The shouts of the sailors, the rattle of the cordage, the farewells of my fellow-passengers, and the cheers of the mob, each and all jarred upon my sensitive nature. I felt sad too. An indescribable feeling, as of some impending calamity, seemed to haunt me. The sea was calm, and the breeze light. There was nothing to disturb the equanimity of the most confirmed of landsmen, yet I felt as if I stood upon the verge of a great though indefinable danger. I have noticed that such presentiments occur often in men of my peculiar temperament, and that they are not uncommonly fulfilled. There is a theory that it arises from a species of second-sight--a subtle spiritual communication with the future. I well remember that Herr Raumer, the eminent spiritualist, remarked on one occasion that I was the most sensitive subject as regards supernatural phenomena that he had ever encountered in the whole of his wide experience. Be that as it may, I certainly felt far from happy as I threaded my way among the weeping, cheering groups which dotted the white decks of the good ship _Spartan_. Had I known the experience which awaited me in the course of the next twelve hours, I would even then at the last moment have sprung upon the shore, and made my escape from the accursed vessel.
