But in other ways, the schoolboy was forecasting the traits of the mature man. There is a mournful letter preserved out of these years, in which the little fellow writes his father after receiving a reprimand for illustrating his letters with pen-and-ink pictures. His inborn faculty would exhibit itself, and the home letters were filled with funny and interesting sketches. But that did not seem to the parental mind a wise use of writing materials. So the embryo artist was warned to curb his passion for illustration. He wrote a few penitent lines in response. “Next comes about the writing. I own that I am very foolish in putting those pictures in my letters, and I won’t do it any more. I never put them in only to the letters home.” Vain promise! It was one more attempt to drive out nature with a pitchfork; and was as unsuccessful--as it deserved to be. The artist-impulse was straining and struggling within him already and was bound to assert itself more and more vigorously till it should triumph in his life-work. So, too, there appeared in these early days the passionate love of nature which was to be a controlling element in his later years. Botany was one of the studies which he insisted upon taking up under Mr. Gunn’s teaching. There was a little family controversy over the matter, growing out of the mother’s fear that the really practical things would be neglected in this passion for nature-study. It sounds strange enough, at this distance in time, with all the light of the boy’s later life, to read the mother’s anxious words: “We wish [Mr. Gunn] to judge and direct in all these things, but I was afraid your own wish and the way I spoke to you about the delight of studying Botany, might have led you to speak so positively in choosing it, that he would suppose it was by our direction. If you really do take up Botany you must expect to find that it is not all play either. There are hard things to remember, and you must make up your mind to work at them bravely and perseveringly if you are determined to make them yours.” A little sentence later in the same letter shows the bent of the boy. His mother, referring to a recent visit of his father to the school, remarks: “I was afraid when your father told me how he found you in the calamus swamp, that you would be sick.” That tells an interesting story of boyish passion for plants. And so do the little fellow’s letters home. Very early in his life at the Gunnery he wrote to his father:
