Last Sunday, or the 14th, I walked on Loring’s Pond to three or four islands there which I had never visited, not having a boat in the summer. On one containing an acre or two, I found a low, branching shrub frozen into the edge of the ice, with a fine spicy scent somewhat like sweet-fern and a handsome imbricate bud. When I rubbed the dry-looking fruit in my hands, it felt greasy and stained them a permanent yellow, which I could not wash out; it lasted several days, and my fingers smelled medicinal. I conclude that it is sweet-gale, and we named the island Myrica Island.
On those unfrequented islands, too, I noticed the red osier or willow, that common hard-berried plant with small red buds,[102] apparently two kinds of swamp-pink buds, some yellow, some reddish, a brittle, rough yellowish bush with handsome pinkish shoots; in one place in the meadow the greatest quantity of wild rose hips of various forms that I ever saw, now slightly withered; they were as thick as winterberries.
I noticed a bush covered with cocoons which were artfully concealed by two leaves wrapped round them, one still hanging by its stem, so that they looked like a few withered leaves left dangling. The worm, having first encased itself in another leaf for greater protection, folded more loosely around itself one of the leaves of the plant, taking care, however, to encase the leaf-stalk and the twig with a thick and strong web of silk, so far from depending on the strength of the stalk, which is now quite brittle. The strongest fingers cannot break it, and the cocoon can only be got off by slipping it up and off the twig. There they hang themselves secure for the winter, proof against cold and the birds, ready to become butterflies when new leaves push forth.[103]
The snow everywhere was covered with snow-fleas like pepper. When you hold a mass in your hand, they skip and are gone before you know it. They are so small that they go through and through the new snow. Sometimes when collected they look like some powder which the hunter has spilled in the path.
Dec. 17. Flint’s Pond apparently froze completely over last night. It is about two inches thick. Walden is only slightly skimmed over a rod from the shore. I noticed, where it had been frozen for some time near the shore of Flint’s Pond and the ice was thicker and whiter, there were handsome spider-shaped dark places, where the under ice had melted, and the water had worn it running through,—a handsome figure on the icy carpet.
I noticed when the snow first came that the days were very sensibly lengthened by the light being reflected from the snow. Any work which required light could be pursued about half an hour longer. So that we may well pray that the ground may not be laid bare by a thaw in these short winter days.
Dec. 19. Yesterday I tracked a partridge in the new-fallen snow, till I came to where she took to flight, and I could track her no further. I see where the snowbirds have picked the seeds of the Roman wormwood and other weeds and have covered the snow with the shells and husks. The smilax berries are as plump as ever. The catkins of the alders are as tender and fresh-looking as ripe mulberries. The dried choke-cherries so abundant in the swamp are now quite sweet. The witch-hazel is covered with fruit and drops over gracefully like a willow, the yellow foundation of its flowers still remaining. I find the sweet-gale (Myrica) by the river also. The wild apples are frozen as hard as stones, and rattle in my pockets, but I find that they soon thaw when I get to my chamber and yield a sweet cider.[104] I am astonished that the animals make no more use of them.
Dec. 22. The apples are now thawed. This is their first thawing. Those which a month ago were sour, crabbed, and uneatable are now filled with a rich, sweet cider which I am better acquainted with than with wine. And others, which have more substance, are a sweet and luscious food,—in my opinion of more worth than the pineapples which are imported from the torrid zone. Those which a month ago I tasted and repented of it, which the farmer willingly left on the tree, I am now glad to find have the property of hanging on like the leaves of the shrub oak. It is a way to keep cider sweet without boiling. Let the frost come to freeze them first solid as stones, and then the sun or a warm winter day—for it takes but little heat—to thaw them, and they will seem to have borrowed a flavor from heaven through the medium of the air in which they hang. I find when I get home that they have thawed in my pocket and the ice is turned to cider. But I suspect that after the second freezing and thawing they will not be so good. I bend to drink the cup and save my lappets. What are the half-ripe fruits of the torrid south, to this fruit matured by the cold of the frigid north. There are those crabbed apples with which I cheated my companion, and kept a smooth face to tempt him to eat. Now we both greedily fill our pockets with them, and grow more social with their wine. Was there one that hung so high and sheltered by the tangled branches that our sticks could not dislodge it? It is a fruit never brought to market that I am aware of,—quite distinct from the apple of the markets, as from dried apple and cider. It is not every winter that produces it in perfection.[105]
In winter I can explore the swamps and ponds. It is a dark-aired winter day, yet I see the summer plants still peering above the snow. There are but few tracks in all this snow. It is the Yellow Knife River or the Saskatchewan. The large leafy lichens on the white pines, especially on the outside of the wood, look almost a golden yellow in the light reflected from the snow, while deeper in the wood they are ash-colored. In the swamps the dry, yellowish-colored fruit of the poison dogwood hangs like jewelry on long, drooping stems. It is pleasant to meet it, it has so much character relatively to man. Here is a stump on which a squirrel has sat and stripped the pine cones of a neighboring tree. Their cores and scales lie all around. He knew that they contained an almond[106] before the naturalist did. He has long been a close observer of Nature; opens her caskets. I see more tracks in the swamps than elsewhere.
Dec. 23. Here is an old-fashioned snow-storm. There is not much passing on railroads. The engineer says it is three feet deep above. Walden is frozen, one third of it, though I thought it was all frozen as I stood on the shore on one side only. There is no track on the Walden road. A traveller might cross it in the woods and not be sure it was a road. As I pass the farmers’ houses I observe the cop [sic] of the sled propped up with a stick to prevent its freezing into the snow. The needles of the pines are drooping like cockerels’ feathers after a rain, and frozen together by the sleety snow. The pitch pines now bear their snowy fruit.
