It is time now to bring our philosophy out of doors.

June 4. 

P. M. — To Bare Hill. 

The early potentilla is now erect in the June grass. 

Salix tristis is going to seed, showing some cotton; also some S. rostrate. 

I am surprised to see some kind of fish dart away in Collier's veronica ditch, for it about dries up and has no outlet. 

I observed yesterday, the first time this year, the lint on the smooth surface of the Assabet at the Hemlocks, giving the water a stagnant look. It is an agreeable phenomenon to me, as connected with the season and suggesting warm weather. I suppose it to be the down from the new leaves which so rapidly become smooth. There may be a little pitch pine pollen with it now. The current is hardly enough to make a clear streak in it here and there. The stagnant-looking surface, where the water slowly circles round in that great eddy, has the appearance of having been dusted over. This lint now covers my clothes as I go through the sprout- lands, but it gets off remarkably before long. Each under side of a leaf you strike leaves the mark of its lint on your clothes, but it is clean dirt and soon wears off. 

One thing that chiefly distinguishes this season from three weeks ago is that fine serene undertone or earth-song as we go by sunny banks and hillsides, the creak of crickets, which affects our thoughts so favorably, imparting its own serenity. It is time now to bring our philosophy out of doors. Our thoughts pillow themselves unconsciously in the troughs of this serene, rippling sea of sound. Now first we begin to be peripatetics. No longer our ears come in contact with the bold echoing earth, but everywhere recline on the spring cushion of a cricket's chirp. These rills that ripple from every hillside become at length a universal sea of sound, nourishing our ears when we are most unconscious. 

In that first apple tree at Wyman's an apparent hairy woodpecker's nest (from the size of the bird), about ten feet from ground. The bird darts away with a shrill, loud chirping of alarm, incessantly repeated, long before I get there, and keeps it up as long as I stay in the neighborhood. The young keep up an in cessant fine, breathing peep which can be heard across the road and is much increased when they hear you approach the hole, they evidently expecting the old bird. 

I perceive no offensive odor. I saw the bird fly out of this hole, May 1st, and probably the eggs were laid about that time. Vide it next year. 

In the high pasture behind Jacob Baker's, soon after coming out of the wood, I scare up a bay-wing. She runs several rods close to the ground through the thin grass, and then lurks behind tussocks, etc. The nest has four eggs, dull pinkish-white with brown spots; nest low in ground, of stubble lined with white horse hair. 

Carya glabra [Carya glabra – pignut hickory], apparently a day at least. 

Oldenlandia on Bare Hill, along above wall opposite the oak, a rod or more off and westerly. Apparently several days at least, but it appears not to do well. It has a dry, tufted look, somewhat like young savory- leaved aster, on the bare rocky hill and in the clear spaces between the huckleberry bushes. Reminds me of a heath. Does not blossom so full as once I saw it. 

Arethusa. 

Crimson fungus (?) on black birch leaves, as if bespattered with blood.

H. D. Thoreau, Journal, June 4, 1857

The early potentilla is now erect in the June grass. See June 4, 1855 (“There are now many potentillas ascendant.”)

Each under side of a leaf you strike leaves the mark of its lint on your clothes, but it is clean dirt and soon wears off. See June 4, 1855 (“Lint comes off on to clothes from the tender leaves, but it is clean dirt and all gone when you get home. . .”); June 4, 1854 (“ The surface of the still water nowadays looking like dust at a little distance. Is it the down of the leaves blown off? . . .”)

That fine serene undertone or earth-song . . . imparting its own serenity. See June 4, 1854 (“These warm and dry days, which put spring far behind, the sound of the cricket at noon has a new value and significance, so serene and cool . . ..”) ;May 12, 1857 (“The spirit of its earth-song, of its serene and true philosophy, was breathed into me, and I saw the world as through a glass, as it lies eternally”);; May 22, 1854 (“The song suggests lateness, but only as we come to a knowledge of eternity after some acquaintance with time. . . . . Only in their saner moments do men hear the crickets. . . .A quire has begun which pauses not for any news, for it knows only the eternal.”); June 1, 1856 (“Was soothed and cheered by I knew not what at first, but soon detected the now more general creak of crickets”); June 13, 1851 ("I listen to the ancient, familiar, immortal, dear cricket sound under all others, and as these cease I become aware of the general earth-song.”)  June 17, 1852 (“The earth-song of the cricket! Before Christianity was, it is. Health! health! health! is the burden of its song. ”); July 14, 1851 (“It is a sound from within, not without.You cannot dispose of it by listening to it. In proportion as I am stilled I hear it. It reminds me that I am a denizen of the earth.”);

The [peep of the young] is much increased when they hear you approach the hole, they evidently expecting the old bird. I perceive no offensive odor. See June 10, 1856 ("They utter their squeaking hiss whenever I cover the hole with my hand, apparently taking it for the approach of the mother. A strong, rank fetid smell issues from the hole.?”)  

A bay-wing . . .  The nest has four eggs, dull pinkish-white with brown spots. . . .See May 18, 1855 ("At Clamshell a bay-wing sparrow’s nest, four eggs (young half hatched) -- some black-spotted, others not.”); May 27, 1856 ("Fringilla melodia’s nest in midst of swamp, with four eggs . . . with very dark blotches"); May 31, 1856 (“A ground-bird’s nest (melodia or graminea.), with six of those oblong narrow gray eggs speckled with much brown at end. . . .The bird would steal out through the grass when I came within a rod, and then, after running a rod or two, take to wing.”)

Oldenlandia on Bare Hill . . . See July 8, 1857 ("Edith Emerson shows me Oldenlandia purpurea var. longifolia, which she saw very abundantly in bloom on the Blue Hills . . .”)
