He always held himself in a kind of reserve with his friend, as if he had said, "Let us respect our personality, and not make a 'mess' of friendship." He saw, with Emerson, the risk of degrading it to trivial conveniency. "Why insist on rash personal relations with your friend?" "Leave this touching and clawing." Yet I would not give an unfair notion of his aloofness, his fine sense of the sacredness of the me and the not-me. And, at the risk of not being believed, I will relate an incident, which was often repeated. Calvin had the practice of passing a portion of the night in the contemplation of its beauties, and would come into our chamber over the roof of the conservatory through the open window, summer and winter, and go to sleep on the foot of my bed. He would do this always exactly in this way; he never was content to stay in the chamber if we compelled him to go upstairs and through the door. He had the obstinacy of General Grant. But this is by the way. In the morning, he performed his toilet and went down to breakfast with the rest of the family. Now, when the mistress was absent from home, and at no other time, Calvin would come in the morning, when the bell rang, to the head of the bed, put up his feet and look into my face, follow me about when I rose, "assist" at the dressing, and in many purring ways show his fondness, as if he had plainly said, "I know that she has gone away, but I am here." Such was Calvin in rare moments. He had his limitations. Whatever passion he had for nature, he had no conception of art. There was sent to him once a fine and very expressive cat's head in bronze, by Fremiet. I placed it on the floor. He regarded it intently, approached it cautiously and crouchingly, touched it with his nose, perceived the fraud, turned away abruptly, and never would notice it afterward. On the whole, his life was not only a successful one, but a happy one. He never had but one fear, so far as I know: he had a mortal and a reasonable terror of plumbers. He would never stay in the house when they were here. No coaxing could quiet him. Of course he did n't share our fear about their charges, but he must have had some dreadful experience with them in that portion of his life which is unknown to us. A plumber was to him the devil, and I have no doubt that, in his scheme, plumbers were foreordained to do him mischief. In speaking of his worth, it has never occurred to me to estimate Calvin by the worldly standard. I know that it is customary now, when any one dies, to ask how much he was worth, and that no obituary in the newspapers is considered complete without such an estimate. The plumbers in our house were one day overheard to say that, "They say that she says that he says that he wouldn't take a hundred dollars for him." It is unnecessary to say that I never made such a remark, and that, so far as Calvin was concerned, there was no purchase in money.
