Our philosopher mistakes his own dominant mood for the constant mood of nature. But nature has no constant mood. No more have we. Dawn and dusk are different moods. The roll of the prairie is unlike the temper of a winding cowpath in a New England pasture. Nature is not always sublime, awful, and mysterious; and no one but a philosopher is persistently contemplative. Indeed, at four o’clock on a June morning in some old apple orchard, even the philosopher would shout,— “Hence, loathèd melancholy!” He is in no mind for meditation; and it is just possible, before the day is done, that the capture of a drifting seed of the dandelion and the study of its fairy wings might so add to the wonder, if not to the sweetness, of the flower, as to give him thought for a sermon. There are times when the companionship of your library is enough; there are other times when you want a single book, a chapter, a particular poem. It is good at times just to know that you are turning with the earth under the blue of the sky; and just as good again to puzzle over the size of the spots in the breasts of our several thrushes. For I believe you can hear more in the song when you know it is the veery and not the wood thrush singing. Indeed, I am acquainted with persons who had lived neighbors to the veery since childhood, and never had heard its song until the bird was pointed out to them. Then they could not help but hear. No amount of familiarity will breed contempt for your fields. Is the summer’s longest, brightest day long enough and bright enough, to dispel the brooding mystery of the briefest of its nights? And tell me, what of the vastness and terror of the sea will the deep dredges ever bring to the surface, or all the circumnavigating drive to shore? The nature-lover is a man in a particular mood; the nature-student is the same man in another mood, as the fading shadows of the morning are the same that lengthen and deepen in the afternoon. There are times when he will go apart into the desert places to pray. Most of the time, however, he will live contentedly within sound of the dinner horn, glad of the companionship of his bluebirds, chipmunks, and pine trees. This is best. And the question most frequently asked me is, How can I come by a real love for my pine trees, chipmunks, and bluebirds? How can I know real companionship with nature?
