See what a powerful hold our ancient superstitions have upon us: two weeks ago, when Livy committed an incredible imprudence and by consequence was promptly stricken down with a heavy triple attack--influenza, bronchitis, and a lung affected--she recognized the gravity of the situation, and her old superstitions rose: she thought she ought to send for a doctor--Think of it--the last man in the world I should want around at such a time. Of course I did not say no--not that I was indisposed to take the responsibility, for I was not, my notion of a dangerous responsibility being quite the other way--but because it is unsafe to distress a sick person; I only said we knew no good doctor, and it could not be good policy to choose at hazard; so she allowed me to send for Kellgren. To-day she is up and around--cured. It is safe to say that persons hit in the same way at the same time are in bed yet, and booked to stay there a good while, and to be in a shackly condition and afraid of their shadows for a couple of years or more to come. It will be seen by the foregoing that Mark Twain's interest in the Kellgren system was still an ardent one. Indeed, for a time he gave most of his thought to it, and wrote several long appreciations, perhaps with little idea of publication, but merely to get his enthusiasm physically expressed. War, however, presently supplanted medicine--the Boer troubles in South Africa and the Boxer insurrection in China. It was a disturbing, exciting year. ***** To W. D. Howells, in Boston: WELLINGTON COURT, KNIGHTSBRIDGE, Jan. 25, 1900. DEAR HOWELLS,--If you got half as much as Pond prophesied, be content and praise God--it has not happened to another. But I am sorry he didn't go with you; for it is marvelous to hear him yarn. He is good company, cheery and hearty, and his mill is never idle. Your doing a lecture tour was heroic. It was the highest order of grit, and you have a right to be proud of yourself. No mount of applause or money or both could save it from being a hell to a man constituted as you are. It is that even to me, who am made of coarser stuff. I knew the audiences would come forward and shake hands with you--that one infallible sign of sincere approval. In all my life, wherever it failed me I left the hall sick and ashamed, knowing what it meant.
