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' labours, and if my interest reaches the enthusiastic point, I smoke more. I smoke with all my might, and allow no intervals. MARK TWAIN. March 14, 1882. MR. CORNELIUS WALFORD, F. S. S., F. I. A. The subject you enquire about is one of vital consequence to brain-workers. I am distinctly of opinion that all stimulants are decidedly injurious to the physical system, and that as a consequence they tend to weaken and destroy the mental powers. I believe tobacco to be a more insidious stimulant than alcoholic beverages. It can be indulged in more constantly without visible degradation; but surely it saps the powers of the mind. In this view I gave it up some years ago. Many men say they smoke to make them think. I notice that a number of them seem to think to very small purpose, either for themselves or mankind generally. I am not a total abstainer, and theoretically have had a belief that pure wine ought to be beneficial to the human system. In practice I have not found it so, though I have always been a very moderate drinker. I certainly never drank a glass of wine or any other liquor in view of mental stimulus, and did not know it was ever seriously regarded as having any such effect, except in so far as it might invigorate the body, which I now find it does not do; but in case of sedentary occupations is positively injurious in its effects. Until mankind can rise above beer and tobacco, the race will remain degraded, as it now is, mentally, socially and physically. P.S.--I have never had so large an amount of mental labour on hand as now--three works in the press (including an encyclopedia, whereof all the articles are written by myself), all requiring much thought and research. I am taking no stimulants whatever. CORNELIUS WALFORD. March 9, 1882. MR. G. F. WATTS, R. A.
