I have not had a large experience in the matter of alcoholic drinks. I find that about two glasses of champagne are an admirable stimulant to the tongue, and is, perhaps, the happiest inspiration for an after dinner speech which can be found; but, as far as my experience goes, wine is a clog to the pen, not an inspiration. I have never seen the time when I could write to my satisfaction after drinking even one glass of wine. As regards smoking, my testimony is of the opposite character. .......
I repeated the experiment once more, when I was thirty-four, and ceased from smoking during a year and a half. My health did not improve, because it was not possible to improve health which was already perfect. As I never permitted myself to regret this abstinence, I experienced no sort of inconvenience from it. I wrote nothing but occasional magazine articles during this time, and as I never wrote one except under strong impulse, I observed no lapse of facility. But by and by I sat down with a contract behind me to write a book of five or six hundred pages—the book called “Roughing it”— and then I found myself most seriously obstructed. I was three weeks writing six chapters. Then I gave up the fight, resumed my three hundred cigars, burned the six chapters, and wrote the book in three months, without any bother or difficulty. I find cigar smoking to be the best of all inspirations for the pen, and, in my particular case, no sort of detriment to the health. During eight months of the year I am at home, and that period is my holiday. In it I do nothing but very occasional miscellaneous work; therefore, three hundred cigars a month is a sufficient amount to keep my constitution on a firm basis. During the family’s summer vacation, which we spend elsewhere, I work five hours every day, and five days in every week, and allow no interruption under any pretext. I allow myself the fullest possible marvel of inspiration; consequently, I ordinarily smoke fifteen cigars during my five hours’ labors, and if my interest reaches the enthusiastic point, I smoke more. I smoke with all my might, and allow no intervals.
