in Thoreau’s Journal:

Must be out-of-doors enough to get experience of wholesome reality—as a ballast to thought and sentiment. Health requires this relaxation, this aimless life. This life in the present.

Let a man have thought what he will of Nature in the house—she will still be novel outdoors. I keep out of doors for the sake of the mineral, vegetable, and animal in me….My thought is a part of the meaning of the world, and hence I use a part of the world as a symbol to express my thought.

in Thoreau’s Journal:

By fall I mean literally the falling of the leaves, though some mean by it the changing or the acquisition of a brighter color. 

This I call the autumnal tint, the ripening to the fall.

in Thoreau’s Journal:

What is Nature unless there is an eventful human life passing within her?

Many joys and many sorrows are the lights and shadows in which she shows most beautiful.

in Thoreau’s Journal:  

 It is a bright, clear, warm November day. I feel blessed. I love my life. I warm toward all nature.

The woods are now much more open than when I last observed them; the leaves have fallen, and they let in light, and I see the sky through them as through a crow’s wing in every direction. 

in Thoreau’s Journal:

The wild apples are now getting palatable. I find a few left on distant trees—which the farmer thinks it not worth his while to gather—he thinks that he has better in his barrels, but he is mistaken unless he has a walker’s appetite & imagination—neither of which can he have. These apples cannot be too gnurly & rusty & crabbed (to look at)— The gnurliest will have some redeeming traits even to the eyes— You will discover some evening redness dashed or sprinkled—on some protuberance or in some cavity— It is rare that the summer lets an apple go without streaking or spotting it on some part of its sphere—though perchance one side may only seem to betray that it has once fallen in a brick yard—and the other have been bespattered from a roily ink bottle.

The saunterer’s apple, not even the saunterer can eat in the house.— Some red stains it will have commemorating the mornings & evenings it has witnessed—some dark & rusty blotches in memory of the clouds, & foggy mildewy days that have passed over it—and a spacious field of green reflecting the general face of nature—green even as the fields— Or yellow its ground if it has a sunny flavor—yellow as the harvests—or russet as the hills. The noblest of fruits is the apple. Let the most beautiful or swiftest have it.

in Thoreau’s Journal:

A white frost this morning, lasting late into the day. This has settled the accounts of many plants which lingered still.

What with the rains & frosts & winds the leaves have fairly fallen now— You may say the fall has ended. Those which still hang on the trees are withered & dry —  I am surprised at the change since last Sunday — Looking at the distant woods I perceive that there is no yellow nor scarlet there now— They are (except the evergreens) a mere dull dry red— The autumnal tints are gone.   What life remains is merely at the foot of the leafstalk.  The woods have for the most part acquired their winter aspect— And coarse rustling light colored withered grasses skirt the river & the woodside— 

in Thoreau’s Journal:

When the leaves fall, the whole earth is a cemetery pleasant to walk in. I love to wander and muse over them in their graves, returning to dust again. Here are no lying or vain epitaphs. The scent of their decay is pleasant to me. I buy no lot in the cemetery which my townsmen have just consecrated with a poem and an auction, paying so much for a choice. Here is room enough for me.

in Thoreau’s Journal:

Some afternoons when the lower strata of the atmosphere is filled with a haze like mist the hills in the horizon seem from an eminence are visibly divided into distinct ranges—& it is easy to refer each to its own chain to tops of the chain rising above the mists which fill the vallies.

in Thoreau’s Journal:

This morning I awoke and found it snowing and the ground covered with snow….

Winter, with its inwardness, is upon us. A man is constrained to sit down, and to think.

in Thoreau’s Journal:

This is the season of the fall when the leaves are whirled through the air like flocks of birds,

the season of birch spangles,

when you see afar a few clear-yellow leaves left on the tops of the birches.

in Thoreau’s Journal:

The autumnal tints grow gradually darker & duller— They are doing to a crisp.  But not less rich to my eye  —  And now a hill side near the river exhibits the darkest crispy reds and browns of every hue all agreeably blended—  At the foot next the meadow stands a front rank of smoke like maples bare of leaves—intermixed with yellow birches. Higher up red oaks of various shades of dull red—with yellowish perhaps black oaks intermixed—and walnuts now brown—& near the hill top or rising above the rest perhaps a still yellowed oak….

in Thoreau’s Journal:

The road through the woods this side the powder mill was very gorgeous with the sun shining endwise through it—& the red tints of the deciduous trees now somewhat imbrowned—mingled with the liquid green of the pines.

in Thoreau’s Journal:

October has been the month of Aut. tints. The 1st of the month the tints began to be more general—at which time the frosts began. Though there were scattered brights tints long before—but not till then did the forest begin to be painted.

By the end of the month the leaves will either have fallen or be sered & turned brown by the frosts—for the most part….

in Thoreau’s Journal:

Nature will bear the closest inspection. She invites us to lay our eye level with her smallest leaf, and take an insect view of its plain

in Thoreau’s Journal:

Most leaves now on the water. They fell yesterday—white & red maple—swamp white oak—white birch—black and red oak—hemlock (which has begun to fall), hop-hornbeam, &c &c—

in Thoreau’s Journal:

Green leaves are doubtless handsome in their season, but now that we behold these ripe ones, we are inclined to think that the former are handsome somewhat as green fruits are, as green apples and melons….At this season each leaf becomes a laboratory in which the fairest and brightest colors are compounded.

in Thoreau’s Journal:

The trees repay the earth with interest from what they have taken from it.

in Thoreau’s Journal:

In Lee’s Wood, white pine leaves are now fairly fallen (not pitch pine yet), —a pleasant, soft, but slippery carpet to walk on. They sometimes spread leafy twigs on floors. Would not these be better? Where the pines stand far apart on grassy pasture hillsides, these tawny patches under each tree contrast singularly with the green around. I see them under one such tree completely and evenly covering and concealing the grass, and more than an inch deep, as they lie lightly.

These leaves, like other, broader ones, pass through various hues (or shades) from green to brown, —first yellow, giving the tree that parti-colored look, then pale brown when they fall, then reddish brown after lying on the ground, and then darker and darker brown when decaying.

in Thoreau’s Journal:

What a new beauty the blue of the river acquires, seen at a distance in the midst of the various-tinted woods, great masses of red and yellow, etc. !

It appears as color, which ordinarily it does not, —elysian.

in Thoreau’s Journal: 

This clear, cold, Novemberish light is inspiriting. Some twigs which are bare, and weeds, begin to glitter with the hoary light. The very edge or outline of a tawny or russet hill has this hoary light on it. Your thoughts sparkle like the water surface and the downy twigs. From the shore you look back on the silver-plated river.

The weeds are dressed in their frost jackets, naked down to their close-fitting downy or flannel shirts. Like athletes they challenge the winter, these bare twigs. This cold refines and condenses us. Our spirits are strong, like that pint of cider in the middle of a frozen barrel.
