Perhaps my most surprising bit of good luck was the finding of the Deptford pink. Of this, for some inscrutable reason, one plant still remained green and showed several rosy blossoms, while all its fellows, far and near, were long since bleached and dead. Fortune has her favorites, even among pinks. The frail-looking, early-blooming corydalis (we have few plants that appear less able to bear exposure) was in excellent condition up to the very end of the month, though the one patch then explored was destitute of flowers. These were as pretty as could be--prettier even than in May, I thought--on the 16th, and no doubt might have been found on the 30th, with careful search. The little geranium known as herb-robert is a neighbor of the corydalis, and, like it, stands the cold remarkably well. Its reddening, finely cut leaves were fresh and flourishing, but though I often looked for its flowers, I found only one during the entire month. The storksbill, its less known cousin, does not grow within my limits, but came to me from Essex County, through the kindness of a friend, being one of the six species contributed by her, as I have before mentioned. The hardiness of some of these late bloomers is surprising. It is now the 2d of December, and yesterday the temperature fell about thirty degrees below the freezing-point, yet I notice shepherd's-purse, peppergrass, chickweed, and knawel still bearing fresh-looking flowers. Nor are they the only plants that seem thus impervious to cold. The prostrate young St. John's-wort shoots, for instance, all uncovered and delicate as they are, appear not to know that winter with all its rigors is upon them. It was impossible not to sympathize admiringly with some of my belated asters and golden-rods. Their perseverance was truly pathetic. They had been hindered, but they meant to finish their appointed task, nevertheless, in spite of short days and cold weather. I have especially in mind a plant of _Solidago juncea_. The species is normally one of the earliest, following hard upon _Solidago Canadensis_, but for some reason this particular specimen did not begin to flower till after the first heavy frosts. Indeed, when I first noticed it, the stem leaves were already frost-bitten; yet it kept on putting forth blossoms for at least a fortnight. Whatever may be true of the lilies of the field, this golden-rod was certainly a toiler, and of the most persistent sort. Early in the month the large and hardy Antiopa butterflies were still not uncommon in the woods, and on the 3d--a delightful, summer-like day, in which I made a pilgrimage to Walden--I observed a single clouded-sulphur (Philodice), looking none the worse for the low temperature of the night before, when the smaller ponds had frozen over for the first time.
