The black-oak acorn is a different fruit. Like the tree it seems to have absorbed all the bitterness of the wood. The white oak always seems to me to glow with the generous hospitality of the sunshine, the black oak to be morose and vindictive, a tree of dull days and shadow. I have little excuse for this feeling, unless it is because of their fruits. The two trees grow side by side in the woodland, the black, if anything, the more vigorous in growth, yet the scaly whiteness of the bark of the one always seems hospitable, the rugose blackness of that of the other unfriendly. So with the fruit; the rich flavor of the white oak acorns is inviting, the meracious bitterness of the others is repellent. Out of the fact of this palatableness on the part of the one and repulsiveness on the part of the other has grown a singular condition in the southern states, where the trees as here once grew in equal profusion, side by side in the forests. There it is the custom, and has been since the days of first settlement, to turn swine loose in the forests, where in the autumn they fatten on “mast,” which is an old English name still in use there, but little known in New England. It means forest nuts of any kind, but especially acorns. These southern, forest-feeding swine have so loved the white-oak mast that they have in a large measure kept the trees from reproducing by eating all the seeds. The black-oak mast, on the contrary, they have rejected, as any wise animal would, leaving the seeds to be scattered about in profusion and reproduce more black oaks. Hence a scarcity of white oaks in southern forests where they would be welcome. The oaks are more tenacious of their leaves than any other deciduous tree, though they are fairly early in showing autumn tints. Long after the reds of other trees of the wood are buried in the brown drifts that cover the roots from the too fierce frosts of winter the rich deep crimsons and red-browns of the oak remain. Indeed, the leaves of some species hold on all winter, and let go their grip only reluctantly when pushed off by the swelling buds of next spring’s growth. Their rustle, as they cling to the twigs in December, makes the wood vocal as the winter winds sift the snow softly down among them. Oftentimes before you see the first fine, far-apart flakes of the coming storm you may hear them pat here and there on a resonant oak leaf, and their presence makes the winter outlook more perfectly and comfortingly bleak as the fine flakes whirl through them. Snow amongst perfectly bare twigs fails of its full effect. You need the shiver of its sifting among the dry, persistent leaves of the oaks to realize all the beauty of its bleakness.
