About a year later I received the proofs of _Aliens_ while in Cristobal, Canal Zone. Without exaggeration, I scarcely knew what to do with them. The outward trappings of literature had fallen away from me with the heavy northern clothing which I had discarded on coming south. I was first assistant engineer on a mail-boat serving New Orleans, the West Indies and the Canal Zone. I had become inured once more to an enchanting existence which alternated between bunk and engine-room. I regarded the neatly-bound proof-copy of _Aliens_ with misgiving. My esteemed Chief, a Scotsman in whose family learning is an honorable tradition, suggested an empty passenger cabin as a suitable study. I forget exactly how the proof-reading was dove-tailed into the watch below, but dove-tailed it was, and when the job was done, the book once more sailed across the Atlantic. But I was not satisfied. Through the dense jungle of preoccupying affairs in which I was buried I could see that I was not satisfied. I was trying to eat my cake and have it. I make no complaint. If there be one person for whom I cherish a profound dislike it is the literary character who whines because his circumstances hinder his writing. I was no George Gissing, cursed with a dreary distaste of common toil and mechanical things. I love both the Grecian Isles and gas-burners. But for the moment I had chosen gas-burners, or rather steam engines, and I knew I could not have both. So _Aliens_ went back to London, and I went my daily round of the Caribbean. I felt that for once I could trust the judgment of a first-class publisher. The publishers of this new edition will understand me when I say that an author has no business to trust blindly to the judgment of any house, however first-class. He has no business to do so because that outside estimate of his work must of necessity be based on scanty data. The publisher, for all his enthusiasm, takes a chance, sometimes a pretty long one. An author, as I conceive it, must be his own most uneasy, captious, cantankerous critic. He dare not delegate this job to anyone else, for that way lies the pot-boiler and the formal romance, the "made" book. I was busy, and let go the reins. And I place on record here my gratitude to those who knew enough and cared enough to recall me to my post, that I might deal with the book afresh and do justice to the reader.
