[Perhaps I am more] than usually jealous of my freedom. I feel that my connections with and obligations to society are at present very slight and transient. Those slight labors which afford me a livelihood, and by which I am serviceable to my contemporaries, are as yet a pleasure to me, and I am not often reminded that they are a necessity. So far I am successful, and only he is successful in his business who makes that pursuit which affords him the highest pleasure sustain him. But I foresee that if my wants should be much increased the labor required to supply them would become a drudgery. If I should sell both my forenoons and afternoons to society, neglecting my peculiar calling, there would be nothing left worth living for. I trust that I shall never thus sell my birthright for a mess of pottage.[115] F. Andrew Michaux says that “the species of large trees are much more numerous in North America than in Europe: in the United States there are more than one hundred and forty species that exceed thirty feet in height; in France there are but thirty that attain this size, of which eighteen enter into the composition of the forests, and seven only are employed in building.”[116] The perfect resemblance of the chestnut, beech, and hornbeam in Europe and the United States rendered a separate figure unnecessary. He says the white oak “is the only oak on which a few of the dried leaves persist till the circulation is renewed in the spring.” Had often heard his father say that “the fruit of the common European walnut, in its natural state, is harder than that of the American species just mentioned [the pacane-nut hickory][117] and inferior to it in size and quality.” * * * * * The arts teach us a thousand lessons. Not a yard of cloth can be woven without the most thorough fidelity in the weaver. The ship must be made _absolutely_ tight before it is launched. * * * * * It is an important difference between two characters that the one is satisfied with a happy but level success but the other as constantly elevates his aim. Though my life is low, if my spirit looks upward habitually at an elevated angle, it is as it were redeemed. When the desire to be better than we are is really sincere we are instantly elevated, and so far better already. I lose my friends, of course, as much by my own ill treatment and ill valuing of them, prophaning of them, cheapening of them, as by their cheapening of themselves, till at last, when I am prepared to [do] them justice, I am permitted to deal only with the memories of themselves, their ideals still surviving in me, no longer with their actual selves. We exclude ourselves, as the child said of the stream in which he bathed head or foot. (_Vide_ Confucius.) * * * * *
