For hours, in fall days, I watched the ducks cunningly tack and veer and hold the middle of the pond, far from the sportsman; tricks which they will have less need to practise in Louisiana bayous. When compelled to rise they would sometimes circle round and round and over the pond at a considerable height, from which they could easily see to other ponds and the river, like black motes in the sky; and, when I thought they had gone off thither long since, they would settle down by a slanting flight of a quarter of a mile on to a distant part which was left free; but what beside safety they got by sailing in the middle of Walden I do not know, unless they love its water for the same reason that I do.
House-Warming
In October I went a-graping to the river meadows, and loaded myself with clusters more precious for their beauty and fragrance than for food. There, too, I admired, though I did not gather, the cranberries, small waxen gems, pendants of the meadow grass, pearly and red, which the farmer plucks with an ugly rake, leaving the smooth meadow in a snarl, heedlessly measuring them by the bushel and the dollar only, and sells the spoils of the meads to Boston and New York; destined to be jammed, to satisfy the tastes of lovers of Nature there. So butchers rake the tongues of bison out of the prairie grass, regardless of the torn and drooping plant. The barberry’s brilliant fruit was likewise food for my eyes merely; but I collected a small store of wild apples for coddling, which the proprietor and travellers had overlooked. When chestnuts were ripe I laid up half a bushel for winter. It was very exciting at that season to roam the then boundless chestnut woods of Lincoln—they now sleep their long sleep under the railroad—with a bag on my shoulder, and a stick to open burs with in my hand, for I did not always wait for the frost, amid the rustling of leaves and the loud reproofs of the red squirrels and the jays, whose half-consumed nuts I sometimes stole, for the burs which they had selected were sure to contain sound ones. Occasionally I climbed and shook the trees. They grew also behind my house, and one large tree, which almost overshadowed it, was, when in flower, a bouquet which scented the whole neighborhood, but the squirrels and the jays got most of its fruit; the last coming in flocks early in the morning and picking the nuts out of the burs before they fell, I relinquished these trees to them and visited the more distant woods composed wholly of chestnut. These nuts, as far as they went, were a good substitute for bread. Many other substitutes might, perhaps, be found. Digging one day for fishworms, I discovered the groundnut (Apios tuberosa) on its string, the potato of the aborigines, a sort of fabulous fruit, which I had begun to doubt if I had ever dug and eaten in childhood, as I had told, and had not dreamed it. I had often since seen its crumpled red velvety blossom supported by the stems of other plants without knowing it to be the same. Cultivation has well-nigh exterminated it. It has a sweetish taste, much like that of a frostbitten potato, and I found it better
