If your foot-sense were not sufficiently subtle to note this difference--though if you were much addicted to life in the open woodland it would be--you still might, blindfolded, know the white oak from the black by the sweetness of its acorns. I sometimes think they are more pleasing to the palate than the chestnuts, though they have a slight astringency. Yet their meat is sweeter and, aside from the slight bitterness, has more of flavor, as you will see if you will test first one and then the other. I think you will agree with me that the chestnut flavor is pale and insipid in comparison.
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.
