First, having _admitted_ illness, which I never do if possible to avoid, I must settle your apprehensiveness; it is no new play, or act or scene, simply a calling before the curtain for repetition. I have in these exhausted days only a given amount of strength, and if, by any accident or oversight, I overdraw on my accounts, I am at once bankrupt, and can carry on business no further. Having been in former days accustomed to draw from an unlimited and ever-recruiting stock of strength and health, I find it a difficult problem to solve, how to bring myself down to the necessary economies of my present condition. I cannot realize that a few hours, a few rods, a few steps even, a little overwork at my desk, the quiet arranging of a simple room, a little overrun of company, may use up all my little capital, and I must wait and compromise with my creditors, start business anew on a smaller scale, and work my way up again to the lost point, probably only to lose it again. A month or six weeks ago I committed some one of these extravagances, and immediately comes a notice from my physical banker shutting off my supply of sleep. He had been allowing me nearly seven hours in the four and twenty, but he cut it down to three, two, one, a few minutes, none at all, and so left me for several days and nights, then let it come back in a similar ratio up to--Oh, well, no matter how much, but not _seven hours_, no, nor for a long time to come; but I can get up and walk about my room and sit part of the day; and I write, because it is better for me to write chatty letters, with no thought in them, than to relapse into solid thinking as I would in doing nothing. One sometimes needs to be saved from himself.
