Wild, scudding wind-clouds in the north, spitting cold rain or sleet, with the curved lines of falling rain beneath..

April 25.

Saturday. P. M. — Down Turnpike to Smith's Hill and return by Goose Pond. 

Saw a large old hollow log with the upper side [gone], which [made] me doubt if it was not a trough open at the ends, and suggested that the first trough was perhaps such a hollow log with one side split off and the ends closed. 

It is cool and windy this afternoon. 

Some sleet falls, but as we sit on the east side of Smith's chestnut grove, the wood, though so open and leafless, makes a perfect lee for us, apparently by breaking the force of the wind. A dense but bare grove of slender chestnut trunks a dozen rods wide is a perfect protection against this violent wind, and makes a perfectly calm lee. 

I find that I can very easily make a convenient box of the birch bark, at this season at least, when the sap is running, to carry a moss or other thing in safely. I have only to make three cuts and strip off a piece from a clear space some ten inches long, and then, rolling it up wrong side outward, as it naturally curls backward as soon as taken off (the dry side shrinking, the moist swelling) and so keeps its place, I bend or fold the ends back on it, as if it were paper, and so close them, and, if I please, tie it round with a string of the same bark. This is resilient or elastic, and stands out from a plant, and also is not injured by moisture like paper. When the incision is made now, the crystalline drops of sap follow the knife down the tree. This box dries yellow or straw-colored, with large clouds of green derived from the inner bark. 

The inner bark of the Betula populifolia just laid bare is green with a yellow tinge; that of the B. papyracea is buff. The undermost layer of the outer bark of the last, next to the inner bark, is straw-colored and exceedingly thin and delicate, and smoother to the lips than any artificial tissue. 

Bluets numerous and fully out at the Smith hillside between trough and Saw Mill Brook Falls. 

Got to-day unquestionable Salix humilis in the Britton hollow, north of his shanty, but all there that I saw (and elsewhere as yet) [are] pistillate. It is apparently now in prime, and apparently the next to bloom after the various larger and earlier ones, all which I must call as yet S. discolor. This S. humilis is small-catkined and loves a dry soil. 

A correspondent of the Tribune of April 24th, 1857, who signs "Lyndeborough, N. H., April 15, 1857. J. Herrick," says that he taps his sugar maples four feet from the ground so that cattle may not disturb the buckets, and that the sap will run as freely from the topmost branch as from a root. 

"Any one may learn this fact from the red squirrel, who, by the way, is a famous sugar maker, and knows when to tap a tree and where to do it. He performs his tapping in the highest perpendicular limbs or twigs, and leaves the sun and wind to do the evaporating, and in due season and pleasant weather you will see him come round and with great gusto gather his sirup into his stomach." 

The dense, green, rounded beds of mosses in springs and old water-troughs are very handsome now, — intensely cold green cushions. 

Again we had, this afternoon at 2 o'clock, those wild, scudding wind-clouds in the north, spitting cold rain or sleet, with the curved lines of falling rain beneath. The wind is so strong that the thin drops fall on you in the sunshine when the cloud has drifted far to one side. 

The air is peculiarly clear, the light intense, and when the sun shines slanting under the dark scud, the willows, etc., rising above the dark flooded meadows, are lit with a fine straw-colored light like the spirits of trees. 

I see winkle fungi comparatively fresh, whose green and reddish-brown and pale-buff circles above turn to light and dark slate and white, and so finally fade all to white. 

The beds of fine mosses on bare yellow mouldy soil are now in fruit and very warmly red in the sun when seen a little from one side. 

No pages in my Journal are so suggestive as those which contain a rude sketch. 

Suppose we were to drink only the yellow birch sap and mix its bark with our bread, would not its yellow curls sprout from our foreheads, and our breath and persons exhale its sweet aroma? What sappy vigor there would be in our limbs! What sense we should have to explore the swamps with!

H. D. Thoreau, Journal, April 25, 1857

I find that I can very easily make a convenient box of the birch bark . . . See April 13, 1857 ("I peeled a white birch, getting a piece of bark about ten inches long. I noticed that the birch sap was flowing. This bark at once curled back so as to present its yellow side outward. I . . . tied it round with a strip of birch bark, making a very nice and airy box for the creature, which would not be injured by moisture, far better than any paper, . . .")

Again we had, this afternoon at 2 o'clock, those wild, scudding wind-clouds in the north, spitting cold rain or sleet.  See December 14, 1859( "Snow-storms might be classified. .. . there is sleet, which is half snow, half rain.")

Suppose we were to drink only the yellow birch sap. See April 16, 1857 ("Get birch sap, — two bottles yellow birch and five of black birch. ")

Would not its yellow curls sprout from our foreheads. See  January 4, 1853 ("This is like a fair, flaxen haired sister of the dark-complexioned black birch, with golden ringlets."); February 18, 1854 ("The curls of the yellow birch bark form more or less parallel straight lines up and down on all sides of the tree, like parted hair blown aside by the wind, or as when a vest bursts and blows open."); January 26, 1858 ("The yellow birch . . .might be described as a tree whose trunk or bole was covered with golden and silver shavings glued all over it and dangling in curls. ")

All is moist and dissolving.

January 13.

Still warm and thawing, springlike; no freezing in the night, though high winds. 

I saw yesterday my snowshoe tracks quite distinct, though made January 2d. Though they pressed the snow down four or five inches, they consolidated it, and it now endures and is two or three inches above the general level there, and more white. 

The landscape is now patches of bare ground and snow; much running water with the sun reflected from it. Lately all was clean, dry, and tight. Now, though clear and bright, all is moist and dissolving. 

Walden is covered with puddles, in which you see a dim reflection of the trees and hills on the grayish or light-colored snow-ice.

In the deep hollow this side of Britton's Camp, I hear a singular buzzing sound from the ground, exactly like that of a large fly or bee in a spider's web. I kneel down, and with pains trace it to a small bare spot as big as my hand, amid the snow, and searched there amid the grass stubble for several minutes, putting the grass aside with my fingers, till, when nearest to the spot, not knowing but I might be stung, I use a stick. The sound is incessant, like that of a large fly in agony, but I find neither prey nor oppressor. 

At length I change the tone with my stick, and so trace it to a few spires of dead grass standing in the melted snow water. It is a sound issuing from the earth. 

There is no bubble in the water. Perhaps it is air confined under the frozen ground, now expanded by the thaw, and escaping upward through the water by a hollow grass stem.

H. D. Thoreau, Journal, January 13, 1854

Walden is covered with puddles, in which you see a dim reflection of the trees and hills on the grayish or light-colored snow-ice. See  January 8, 1860 ("The sloshy edges of the puddles are the frames of so many wave-shaped mirrors in which the leather-colored oak leaves, and the dark-green pines and their stems, on the hillside, are reflected. "); February 7, 1857 (“The water on the ice is for the most part several inches deep, and trees reflected in it appear as when seen through a mist or smoke, apparently owing to the color of the ice.”); February 15, 1859 ("We walk through almost invisible puddles on the river and meadows, in which we see the trees, etc., reflected. ")

To Flint's Pond

June 19.

June 19, 2020

Ripple Lake northeast shore is lined with a pale-yellowish pine pollen, though there are no pines within a dozen rods, and those (white pines) on the east. Half of the pool is gray with the dust, as with meal. Is not this paler yellow that of the white pine? So of Goose Pond. Thus these ponds and pools in the woods catch the pine pollen that may be floating in the atmosphere and it is washed up to one side (the northeast side). At Flint's also. They are pollen-ometers. 

The devil's-needles now abound in wood-paths and about the Ripple Lakes. Even if your eyes were shut you would know they were there, hearing the rustling of their wings as they flit by in pursuit of one another.


I follow a distinct fox-path amid the grass and bushes for some forty rods beyond Britton's Hollow, leading from the great fox-hole. It branches on reaching the peach-orchard. 


No doubt by these routes they oftenest go and return to their hole. As broad as a cart-wheel, and at last best seen when you do not look too hard for it.

H. D. Thoreau, Journal, June 19, 1860

These ponds and pools in the woods catch the pine pollen that may be floating in the atmosphere . . . They are pollen-ometers. See note to June 21, 1860 ("As chemists detect the presence of ozone in the atmosphere by exposing to it a delicately prepared paper , so the lakes detect for us thus the presence of the pine pollen in the atmosphere . They are our pollinometers . How much of this invisible dust must be floating in the atmos- phere , and be inhaled and drunk by us at this season !! Who knows but the pollen of some plants may be un- wholesome to inhale , and produce the diseases of the season?");  May 4, 1853 ("Humboldt speaks of its having been proved that pine pollen falls from the atmosphere.");; June 20, 1858 ("Walking in the white pine wood there, I find that my shoes and, indeed, my hat are covered with the greenish-yellow pollen of the white pines, which is now being shed abundantly and covers like a fine meal all the plants and shrubs of the forest floor.");  June 22, 1858 ("I notice, after tipping the water out of my boat under the willows, much evidently pine pollen adhering to the inside of the boat along the water-line. Did it fall into it during my excursion to Holden’s Swamp the 20th, or has it floated through the air thus far?")

A fox-path beyond Britton's Hollow, leading from the great fox-hole. See April 9, 1859 ("A large fox-hole in Britton's hollow, lately dug; an ox-cartload of sand, or more, thrown up on the hill side.")
