The universe built round us.

August 24. 


Let us wander where we will, the universe is built round about us, and we are central still. 

By reason of this, if we look into the heavens, they are concave, and if we were to look into a gulf as bottomless, it would be concave also. 

The sky is curved downward to the earth in the horizon, because I stand in the plain. I draw down its skirts. 

The stars so low there seem loth to go away from me, but by a circuitous path to be remembering and returning to me. 

H. D Thoreau, Journal, August 24, 1841

When one kind of life goes, another comes. The same warm and placid day calls out men and butterflies.

March 28
P. M. — To Cliffs.

After a cloudy morning, a warm and pleasant afternoon. I hear that a few geese were seen this morning.

Israel Rice says that he heard two brown thrashers sing this morning! Is sure because he has kept the bird in a cage. I can’t believe it.

I go down the railroad, turning off in the cut. I notice the hazel stigmas in the warm hollow on the right there, just beginning to peep forth. This is an unobserved but very pretty and interesting evidence of the progress of the season. I should not have noticed it if I had not carefully examined the fertile buds. It is like a crimson star first dimly detected in the twilight. The warmth of the day, in this sunny hollow above the withered sedge, has caused the stigmas to show their lips through their scaly shield. They do not project more than the thirtieth of an inch, some not the sixtieth. The staminate catkins are also considerably loosened. Just as the turtles put forth their heads, so these put forth their stigmas in the spring. How many accurate thermometers there are on every hill and in every valley: Measure the length of the hazel stigmas, and you can tell how much warmth there has been this spring. How fitly and exactly any season of the year may be described by indicating the condition of some flower! 

I go by the springs toward the epigaea. 

It is a fine warm day with a slight haziness. It is pleasant to sit outdoors now, and, it being Sunday, neighbors walk about or stand talking in the sun, looking at and scratching the dry earth, which they are glad to see and smell again. 

In the sunny epigaea wood I start up two Vanessa Antiopa, which flutter about over the dry leaves be fore, and are evidently attracted toward me, settling at last within a few feet. The same warm and placid day calls out men and butterflies. 

It is surprising that men can be divided into those who lead an indoor and those who lead an outdoor life, as if birds and quadrupeds were to be divided into those that lived a within nest or burrow life and [those] that lived without their nests and holes chiefly. How many of our troubles are house-bred! He lives an out door life; i.e., he is not squatted behind the shield of a door, he does not keep himself tubbed. It is such a questionable phrase as an “honest man,” or the “naked eye,” as if the eye which is not covered with a spy glass should properly be called naked.

From Wheeler's plowed field on the top of Fair Haven Hill, I look toward Fair Haven Pond, now quite smooth. There is not a duck nor a gull to be seen on it. I can hardly believe that it was so alive with them yesterday. Apparently they improve this warm and pleasant day, with little or no wind, to continue their journey northward. The strong and cold northwest wind of about a week past has probably detained them. Knowing that the meadows and ponds were swarming with ducks yesterday, you go forth this particularly pleasant and still day to see them at your leisure, but find that they are all gone. No doubt there are some left, and many more will soon come with the April rains. It is a wild life that is associated with stormy and blustering weather. When the invalid comes forth on his cane, and misses improve the pleasant air to look for signs of vegetation, that wild life has withdrawn itself. 

But when one kind of life goes, another comes. This plowed land on the top of the hill — and all other fields as far as I observe — is covered with cobwebs, which every few inches are stretched from root to root or clod to clod, gleaming and waving in the sun, the light flashing along them as they wave in the wind. How much insect life and activity connected with this peculiar state of the atmosphere these imply! Yet I do not notice a spider. Small cottony films are continually settling down or blown along through the air. [A gossamer day. I see them also for a week after.] Does not this gossamer answer to that of the fall? They must have sprung to with one consent last night or this morning and bent new cables to the clods and stubble all over this part of the world. 

The little fuzzy gnats, too, are in swarms in the air, peopling that uncrowded space. They are not confined by any fence. Already the distant forest is streaked with lines of thicker and whiter haze over the successive valleys. 

Walden is open. When? On the 20th it was pretty solid. C. sees a very little ice in it to-day, but probably it gets entirely free to-night.

Fair Haven Pond is open.

[This and Flint's and Walden all open together this year, the latter was so thinly frozen! (For C. says Flint's and Walden were each a third open on the 25th.)]

Sitting on the top of the Cliffs, I look through my glass at the smooth river and see the long forked ripple made by a musquash swimming along over the  meadow. While I sit on these warm rocks, turning my glass toward the mountains, I can see the sun reflected from the rocks on Monadnock, and I know that it would be pleasant to be there too to-day as well as here. I see, too, warm and cosy seats on the rocks, where the flies are buzzing, and probably some walker is enjoying the prospect. 

From this hilltop I overlook, again bare of snow, putting on a warm, hazy spring face, this seemingly concave circle of earth, in the midst of which I was born and dwell, which in the northwest and southeast has a more distant blue rim to it, as it were of more costly manufacture. On ascending the hill next his home, every man finds that he dwells in a shallow concavity whose sheltering walls are the convex surface of the earth, beyond which he cannot see. I see those familiar features, that large type, with which all my life is associated, unchanged. 

Cleaning out the spring on the west side of Fair Haven Hill, I find a small frog, apparently a bullfrog, just come forth, which must have wintered in the mud there. There is very little mud, however, and the rill never runs more than four or five rods before it is soaked up, and the whole spring often dries up in the summer. It seems, then, that two or three frogs, the sole inhabitants of so small a spring, will bury them selves at its head. A few frogs will be buried at the puniest spring-head. 

Coming home, I hear the croaking frogs in the pool on the south side of Hubbard’s Grove. It is sufficiently warm for them at last. 

Near the sand path above Potter's mud-hole I find what I should call twenty and more mud turtles’ eggs close together, which appear to have been dug from a hole close by last year. They are all broken or cracked and more or less indented and depressed, and they look remarkably like my pigeon's egg fungi, a dirty white covered thickly with a pure white roughness, which through a glass is seen to be oftenest in the form of minute but regular rosettes of a very pure white substance. If these are turtles' eggs, –and there is no stem mark of a fungus, – it is remarkable that they should thus come to resemble so closely another natural product, the fungus.

The first lark of the 23d sailed through the meadow with that peculiar prolonged chipping or twittering sound, perhaps sharp clucking.

H. D. Thoreau, Journal, March 28, 1858

I start up two Vanessa Antiopa, which flutter about over the dry leaves before, and are evidently attracted toward me, settling at last within a few feet. See March 28, 1857 ("The broad buff edge of the Vanessa Antiopa’s wings harmonizes with the russet ground it flutters over, and as it stands concealed in the winter, with its wings folded above its back, in a cleft in the rocks, the gray brown under side of its wings prevents its being distinguished from the rocks themselves.") See also A Book of the Seasons,  by Henry Thoreau, the Buff-edged Butterfly

Coming home, I hear the croaking frogs in the pool on the south side of Hubbard’s Grove. It is sufficiently warm for them at last. See March 26, 1860 ("The wood frog may be heard March 15, as this year, or not till April 13, as in’56, — twenty-nine days."); March 15, 1860 ("Am surprised to hear, from the pool behind Lee's Cliff, the croaking of the wood frog. . . . How suddenly they awake! yesterday, as it were, asleep and dormant, to-day as lively as ever they are. The awakening of the leafy woodland pools.."); March 23, 1859 ("I hear a single croak from a wood frog. . . . Thus we sit on that rock, hear the first wood frog's croak"); March 24, 1859 (" Can you ever be sure that you have heard the very first wood frog in the township croak? "); March 26, 1857 ("As I go through the woods by Andromeda Ponds, though it is rather cool and windy in exposed places, I hear a faint, stertorous croak from a frog in the open swamp; at first one faint note only, which I could not be sure that I had heard, but, after listening long, one or two more suddenly croaked in confirmation of my faith, and all was silent again"); March 27, 1853 ("Tried to see the faint-croaking frogs at J. P. Brown's Pond in the woods. They are remarkably timid and shy; had their noses and eyes out, croaking, but all ceased, dove, and concealed themselves, before I got within a rod of the shore."); March 30, 1858 ("Later, in a pool behind Lee's Cliff, I hear them, – the waking up of the leafy pools. . . . I do not remember that I ever hear this frog in the river or ponds. They seem to be an early frog, peculiar to pools and small ponds in the woods and fields.")

The convexity of the earth.

August 11

This morning the river is an inch and a half higher, or within eight inches of the top of Hoar's wall.

August 11, 2016

The other evening, returning down the river, I think I detected the convexity of the earth within a short distance. I saw the western landscape and horizon, reflected in the water fifty rods behind me, all lit up with the reflected sky, though it was a narrow picture. A stroke of my oar and the dark intervening water was interposed like a dark, opaque wall. Moving my head a few inches up or down produced the same effect; i.e., by raising my head three inches I could partially oversee the plane of the water at that point, which was otherwise concealed by the slightest convexity.

P. M. — Walk to Conantum with Mr. Bradford. 

He gives me a sprig of Cassia Marilandica, wild senna, found by Minot Pratt just below Leighton's by the road side. How long? P. thought it in prime August 10th.

Aster puniceus a day or more.

A new sunflower at Wheeler's Bank, this side Corner Spring, which I will call the tall rough sunflower; opened say August 1st (?). (I saw it out the 7th.) It does not correspond exactly to any described. Stem three to six feet high, branched at top, purple with a bloom, roughish, especially the peduncles. Leaves opposite, except a few small ones amid the branches, thick , ovate or ovate-lanceolate, taper-pointed, three-nerved, obscurely and remotely toothed, rough above, smooth and whitish below, abruptly contracted into margined petioles. Scales of the involucre lanceolate, taper-pointed, subequal, exceeding the disk, ciliate; rays eight or nine, one and a half or more inches long, chaff black. Edge of meadow.

Measured a mulgedium, eight feet three inches long and hollow all the way. 

Some boy had fixed an arch-angelica stem so as to conduct the water at the spring close by. 

Elder-berries in a day or two. 

I see some Hypericum angulosum turned a delicate clear purple. 

Polygonum dumetorum at Bittern Cliff, one flower gone to seed (!); say day or two.

7 p. m. — The river has risen about two inches to day, and is now within six inches of the top of Hoar's wall.

H. D. Thoreau, Journal, August 11, 1856

I think I detected the convexity of the earth. . . by raising my head three inches. 
See June 7, 1851 ("You may walk out in any direction over the earth's surface, lifting your horizon, and everywhere your path, climbing the convexity of the globe, leads you between heaven and earth.”);  August 23, 1851 ("We experience pleasure when an elevated field or even road in which we may be walking holds its level toward the horizon at a tangent to the earth, is not convex with the earth’s surface, but an absolute level."); March 28, 1858 ("On ascending the hill next his home, every man finds that he dwells in a shallow concavity whose sheltering walls are the convex surface of the earth, beyond which he cannot see.") See also Samuel Birley Rowbotham ("If the earth is a globe, and is 25,000 English statute miles in circumference, the surface of all standing water must have a certain degree of convexity—every part must be an arc of a circle. From the summit of any such arc there will exist a curvature or declination of 8 inches in the first statute mile. In the second mile the fall will be 32 inches; in the third mile, 72 inches, or 6 feet." ~ wikipedia)

Aster puniceus a day or more. See August 30, 1856 ("The Aster puniceus is hardly yet in prime; its great umbel-shaped tops not yet fully out.")

A new sunflower at Wheeler's Bank, this side Corner Spring, which I will call the tall rough sunflower; opened say August 1st (?). (I saw it out the 7th.) It does not correspond exactly to any described. 
See August 12, 1856 ("Am surprised to see still a third species or variety of helianthus (which may have opened near August 1st, say only a week). Only the first flowers out. At edge of the last clearing south of spring. I cannot identify it."); September 2, 1856 ("A short time ago, I was satisfied that there was but one kind of sunflower (divaricatus) indigenous here. Hearing that one had found another kind, it occurred to me that I had seen a taller one than usual lately, but not so distinctly did I remember this as to name it to him or even fully remember it myself. (I rather remembered it afterward.) But within that hour my genius conducted me to where I had seen the tall plants, and it was the other man's new kind. The next day I found a third kind, miles from there, and, a few days after, a fourth in another direction. It commonly chances that I make my most interesting botanical discoveries when I am in a thrilled and expectant mood, perhaps wading in some remote swamp where I have just found something novel and feel more than usually remote from the town. Or some rare plant which for some reason has occupied a strangely prominent place in my thoughts for some time will present itself. My expectation ripens to discovery. I am prepared for strange things.") See also A Book of the Seasons, by Henry Thoreau, Helianthus

Measured a mulgedium, eight feet three inches long and hollow all the way.
See August 7, 1856 ("One mulgedium at Corner Spring is at least ten feet high and hollow all the way. "); August 12, 1856 ("The mulgedium in that swamp is very abundant and a very stately plant, so erect and soldier-like, in large companies, rising above all else, with its very regular long, sharp, elliptic head and bluish-white flowers.")

Elder-berries in a day or two.
See August 9, 1854 ("'Walden' published. Elder-berries."); August 23, 1856 ("Elder-berries, now looking purple, are weighing down the bushes along fences by their abundance.") See also A Book of the Seasons, by Henry Thoreau, Elder-berries

Hypericum angulosum turned a delicate clear purple.  
See July 25, 1856 ("Up river to see hypericums out.”); July 26, 1856 ("Arranged the hypericums in bottles this morning and watched their opening. The H. angulosum has a pod one-celled (with three parietal placentae), conical, oblong, acute, at length longer than the sepals, purple.”) See also A Book of the Seasons, by Henry Thoreau, St. Johns-wort (Hypericum)

The river has risen about two inches to day, and is now within six inches of the top of Hoar's wall. See August 10, 1856 ("The river has been rising all day. It is between two and a half and three feet higher than ten days ago . . . It is within nine and a half inches of the top of Hoar's wall at 6 p. m. "); August 22, 1856 ("Owing to the rain of the 8th and before, two days and two nights, the river rose to within six inches of the top of Hoar's wall. It had fallen about one half, when the rain began again on the night of the 20th, and again continued about two nights and two days, though so much did not fall as before; but, the river being high, it is now rising fast . . . It is within three inches of the top of Hoar's wall at 7 p. m.")

Between heaven and earth


It is a certain faeryland where we live. 

You may walk out in any direction over the earth's surface, lifting your horizon, and everywhere your path, climbing the convexity of the globe, leads you between heaven and earth the light of the sun and stars and the habitations of man.

I wonder that I ever get five miles on my way, the walk is so crowded with events and phenomena.

How far does our knowledge really extend? We believe that the possibility of the future far exceeds the accomplishment of the past. We find ourselves naturally expecting or prepared for far greater changes than any which we have experienced within the period of distinct memory -- only to be paralleled by experiences which are forgotten. I do not even infer the future from what I know of the past.

I am hardly better acquainted with the past than with the future.

One of those gentle, straight-down rainy days, when the rain begins by spotting the cultivated fields as if shaken from a pepper-box; a fishing day, when I see one neighbor after another, having donned his oil-cloth suit, walking or riding past with a fish-pole, having struck work, - a day and an employment to make philosophers of them all.

H.D. Thoreau, Journal, June 7, 1851


The walk is so crowded with events and phenomena.
See August 30, 1856 ("The more thrilling, wonderful, divine objects I behold in a day, the more expanded and immortal I become.")

It is a certain faeryland where we live.
 See November 21, 1850 ("Seeing the sun falling on a distant white pinewood with mingled gray and green, in an angle where this forest meets a hill covered with shrub oaks, affects me singularly, reinspiring me with all the dreams of my youth. It is a place far away, yet actual and where I have been. It is like looking into dreamland. It is one of the avenues to my future"); June 16, 1854 (" Do I not live in a garden, — in paradise?"); August 6, 1852 ("We live, as it were, within the calyx of a flower.")

I am hardly better acquainted with the past than with the future. Compare May 12, 1857 ("Our past experience is a never-failing capital which can never be alienated, of which each kindred future event reminds us. If you would have the song of the sparrow inspire you a thousand years hence, let your life be in harmony with its strain to-day.”); December 8, 1859 ("Only the poet has the faculty to see present things as if also past and future, as if universally significant.”)

. See June 7, 1854 ("This louring day has been a regular fisherman's day, and I have seen many on the river, a general turnout."); See also January 12, 1855 ("On Flint’s Pond I find Nat Rice fishing. He has not caught one. I asked him what he thought the best time to fish. He said, “When the wind first comes south after a cold spell, on a bright morning.”");  June 26, 1853 ("Many of my fellow-citizens might go fishing a thousand times, perchance, before the sediment of fishing would sink to the bottom and leave their purpose pure, -- before they began to angle for the pond itself.”); December 28, 1856 ("if not catching many fish, still getting what they went for, though they may not be aware of it, i. e. a wilder experience than the town affords.")

wrestling with the melody
that possesses me.
