One of the apparently favorite positions which he assumed was to throw an arm around the corner gas-post, and swing his body back and forth, occasionally, when alone, taking a swing entirely around the post. Another favorite position was to stand with his fists each boring into the hollow of his back over the corresponding hip, with his chest and shoulders thrown well back, and his head erect, looking steadily off into the distance. With regard to this man's station in life, I took little credit to myself for a correct guess; for, in addition to other aids to correct guessing, the store-room on that corner was occupied by an apothecary. When I asked Arthur whether the man was not a physician, "Yes, sir," he replied; "physician, surgeon, and obstetrician; George F. Castleton, A.M., M.D. _He_ ought to get a dry-goods box and a torch-light, and sell 'Hindoo Bitters' in the Public-square. If you jest want to die quick, you know where to go to get it. That fellow salivated me till my teeth can't keep quiet. Oh, he knows it all! Medicine ain't enough to fill his intellecty. _He_ runs the Government and declares war to suit himself. 'Moves around a great deal,' you say? Well, I believe you; but when you see his idees move around you'll quit sighing about his body. Why, sir, that man in a campaign changes his politics every day; nobody ever yet caught up with his religion; and besides, he's a prophet. You jest get back home without touchin' _him_, if you love me, now, please do." All of this was said in a quiet, instructive tone, without much show of feeling even when the teeth were mentioned, and only such emphasis as has been indicated by my italics. Arthur's advice for me to get home without "touching" the doctor, I had no intention of following. My curiosity regarding the man was aroused, and I had determined, if possible, to know him. So far as one could be influenced from a third-story window, I was favorably impressed with him. I judged him to be superlatively erratic, but without an atom of real evil in his being. I had observed from my window an incident that gave me a glance into the man's heart. A poor, dilapidated, distressed negro, evidently seeking help, had come running up to him as he stood near his buggy, at the corner; and the manner in which he pushed the negro into the buggy, himself followed, and then started off at a break-neck speed, left no doubt in my mind that the doctor had a heart as large as the whole world. Once or twice during the long, warm afternoons, his words came to me through the open windows. I was aware that his almost preternaturally bright, quick eyes flashed a glance or two at me as I once or twice stepped rather close to an open window looking out over the lower roof-tops beyond; and I felt that he had given me a niche in his mind, as I had him in mine. I wondered if he had formed mental estimates of my status, and if so whether he had attempted to corroborate them as did I mine, through Arthur.
