Laudator Temporis Acti

Walt Whitman, Specimen Days (The Lesson of a Tree):

I should not take either the biggest or the most picturesque tree to illustrate it. Here is one of my favorites now before me, a fine yellow poplar, quite straight, perhaps 90 feet high, and four thick at the butt. How strong, vital, enduring! how dumbly eloquent! What suggestions of imperturbability and being, as against the human trait of mere seeming. Then the qualities, almost emotional, palpably artistic, heroic, of a tree; so innocent and harmless, yet so savage. It is, yet says nothing. How it rebukes by its tough and equable serenity all weathers, this gusty-temper'd little whiffet, man, that runs indoors at a mite of rain or snow. Science (or rather half-way science) scoffs at reminiscences of dryad and hamadryad, and of trees speaking. But, if they don't, they do as well as most speaking, writing, poetry, sermons—or rather they do a great deal better. I should say indeed that those old dryad-reminiscences are quite as true as any, and profounder than most reminiscences we get. ("Cut this out," as the quack mediciners say, and keep by you.) Go and sit in a grove or woods, with one or more of those voiceless companions, and read the foregoing, and think.

Yellow poplar is a common name for the tulip tree (Liriodendron tulipifera). There are some good photographs of tulip trees by Gregory Palermo on his blog Plainfield Trees.
