I see no reason to regret my determination to stay. "On contrary," as Agassiz says, as I begin to use my eyes a little every day, I feel like an entirely new being. Everything revives within and without, and I now feel sure that I shall learn. I have profited a great deal by hearing Agassiz talk, not so much by what he says, for never did a man utter a greater amount of humbug, but by learning the way of feeling of such a vast practical engine as he is. No one sees farther into a generalization than his own knowledge of details extends, and you have a greater feeling of weight and solidity about the movement of Agassiz's mind, owing to the continual presence of this great background of special facts, than about the mind of any other man I know. He has a great personal tact too, and I see that in all his talks with me he is pitching into my loose and superficial way of thinking.... Now that I am become more intimate with him, and can talk more freely to him, I delight to be with him. I only saw his defects at first, but now his wonderful qualities throw them quite in the background. I am convinced that he is the man to do me good. He will certainly have earned a holiday when he gets home. I never saw a man work so hard. Physically, intellectually and socially he has done the work of ten different men since he has been in Brazil; the only danger is of his overdoing it.... I am beginning to get impatient with the Brazilian sleepiness and ignorance. These Indians are particularly exasperating by their laziness and stolidity. It would be amusing if it were not so infuriating to see how impossible it is to make one hurry, no matter how imminent the emergency. How queer and how exhilarating all those home letters were, with their accounts of what every one was doing, doing, doing. To me, just awakening from my life of forced idleness and from an atmosphere of Brazilian inanity, it seemed as if a little window had been opened and a life-giving blast of one of our October nor'westers had blown into my lungs for half an hour. I had no idea before of the real greatness of American energy. They wood up the steamer here for instance at the rate (accurately counted) of eight to twelve logs a minute. It takes them two and one-half hours to put in as much wood as would go in at home in less than fifteen minutes. [Illustration: A Pencil Sketch from a Pocket Note-Book.]
