On hillside north of river above powder-mills the _Pycnanthemum incanum_ (mountain mint, calamint) and the _Lespedeza violacea_. Saw what I thought a small red dog in the road, which cantered along over the bridge this side the powder-mills and then turned into the woods. This decided me—this turning into the woods—that it was a fox. The dog of the woods, the dog that is more at home in the woods than in the roads and fields. I do not often see a dog turning into the woods. Some large white (?) oak acorns this side the last-named bridge. A few oaks stand in the pastures still, great ornaments. I do not see any young ones springing up to supply their places. Will there be any a hundred years hence? These are the remnants of the primitive wood, methinks. We are a young people and have not learned by experience the consequence of cutting off the forest. One day they will be planted, methinks, and nature reinstated to some extent. I love to see the yellow knots and their lengthened stain on the dry, unpainted pitch[?]-pine boards on barns and other buildings,—the Dugan house, for instance. The indestructible yellow fat! it fats my eyes to see it; worthy for art to imitate, telling of branches in the forest once. _Sept 5._ No doubt, like plants, we are fed through the atmosphere, and the varying atmospheres of various seasons of the year feed us variously. How often we are sensible of being thus fed and invigorated! And all nature contributes to this aerial diet its food of finest quality. Methinks that in the fragrance of the fruits I get a finer flavor, and in beauty (which is appreciated by sight—the taste and smell of the eye) a finer still. As Wilkinson says, “the physical man himself is the builded aroma of the world. This then, at least, is the office of the lungs—to drink the atmosphere with the planet dissolved in it.” “What is the import of _change of air_, and how each pair of lungs has a _native air_ under some one dome of the sky.” Wilkinson’s book to some extent realizes what I have dreamed of,—a return to the primitive analogical and derivative senses of words. His ability to trace analogies often leads him to a truer word than more remarkable writers have found; as when, in his chapter on the human skin, he describes the papillary cutis as “an encampment of small conical tents coextensive with the surface of the body.” The faith he puts in old and current expressions as having sprung from an instinct wiser than science, and safely to be trusted if they can be interpreted. The man of science discovers no world for the mind of man with all its faculties to inhabit. Wilkinson finds a _home_ for the imagination, and it is no longer outcast and homeless. All perception of truth is the detection of an analogy; we reason from our hands to our head.
