“ We are now in a position to understand generally the changes that convert the female flower into the cupped acorn. The fertilized oöspore becomes the embryo (Fig. 35, x) ; it grows at the expense of the contents of the embryo-sac, and develops a radicle, a plumule, and two relatively large cotyledons, which soon become so big that they occupy the whole space in the sac (Fig. 36) . Moreover, the embryo-sac increases to make more room for this growing embryo. And now comes in a curious point. We saw that the ovary consisted of three chambers, each containing two ovules ”

“ Summing up these essential features of the structure of the ripe acorn and its contents, we find that the fruit contains within its pericarp (which is a more or less complex series of layers, of which the outermost is hard) the seed; that this seed comprises a membranous testa inclosing an embryo; and that the embryo is composed of two huge cotyledons, a minute radicle, and a still more minute plumule; and that the tip of the radicle is turned towards the pointed end of the acorn, lying just inside the membranes. ”

Portrait of Gilbert Keith Chesterton Gilbert Keith Chesterton,  Tremendous Trifles (1909)

“ The Wind and the Trees I am sitting under tall trees, with a great wind boiling like surf about the tops of them, so that their living load of leaves rocks and roars in something that is at once exultation and agony. I feel, in fact, as if I were actually sitting at the bottom of the sea among mere anchors and ropes, while over my head and over the green twilight of water sounded the everlasting rush of waves and the toil and crash and shipwreck of tremendous ships. The wind tugs at the trees as if it might pluck them root and all out of the earth like tufts of grass. ”
