in Thoreau’s Journal:

A pure brook is a very beautiful object to study minutely.  It will bear the closest inspection, even to the fine air-bubbles, like minute globules of quicksilver, that lie on its bottom. The minute particles or spangles of golden mica in these sands, when the sun shines on them, remind one of the golden sands we read of. Everything is washed clean and bright, and the water is the best glass through which to see it….

in Thoreau’s Journal:

The Saxifrage is beginning to be abundant, elevating its flowers somewhat, pure trustful white amid its pretty notched and reddish cup of leaves.

The white saxifrage is a response from earth to the increased light of the year…

April 9, 1853 in Thoreau’s Journal:

The male red maple buds now show 8 or 10 (counting everything) scales alternately crosswise—& the pairs successively brighter red or scarlet, which will account for the gradual reddening of their tops. They are about ready to open.

in Thoreau’s Journal:

The epigaea is not quite out. 

The earliest peculiarly woodland herbaceous flowers are epigaea, thalictrum, and (by the first of May) Viola pedata.  These grow quite in the woods amid dry leaves, nor do they depend so much on water as the very earliest flowers. I am perhaps more surprised by the growth of the Viola pedata leaves by the side of paths amid the shrub oaks, and half covered with oak leaves, than by any other growth, the situation is so dry and the surrounding bushes so apparently lifeless.

in Thoreau’s Journal:

As to which are the earliest flowers, it depends on the character of the season, and ground bare or not, meadows wet or dry, etc., etc., also on the variety of soils and localities within your reach.

in Thoreau’s Journal:

One thing I may depend on, there has been no idling with the flowers. Nature loses not a moment, takes no vacation. They advance as steadily as a clock. 

in Thoreau’s Journal:

Begin to look off the hills & see the landscape again through a slight haze, with warm wind on the cheek.

in Thoreau’s Journal:

All the earth is bright. the very pines glisten–& the water is a bright blue….

Not only are the evergreens brighter–but the pools–as that upland one behind Lees–the ice as well as snow– about their edges being now completely melted–have a peculiarly warm–watery & bright April look–as if ready to be inhabited by frogs.

in Thoreau’s Journal:

It is surprising how the earth on bare south banks begins to show some greenness in its russet cheeks in this rain and fog—a precious emerald-green tinge—almost like a green mildew, the growth of the night — a green blush suffusing her cheek — heralded by twittering birds. This sight is no less interesting than the corresponding bloom & ripe blush of the fall. How encouraging to perceive again that faint tinge of green, spreading amid the russet on earth’s cheeks! I revive with Nature—her victory is mine.

in Thoreau’s Journal:

It is evident that it depends on the character of the season whether this flower or that is the most forward; whether there is more or less snow or cold or rain, etc.

in Thoreau’s Journal:

With this flower, so much more flowerlike or noticeable than any yet—begins a new era in the flower season. 

in Thoreau’s Journal:

The spring advances in spite of snow and ice and cold even.

 in Thoreau’s Journal:  

Intended to get up early this morning and commence a series of spring walks, but clouds and drowsiness prevented…How can one help being an early riser and walker in that season when the birds begin to twitter and sing in the morning?

in Thoreau’s Journal:

This which is a chilling wind to my fellow is decidedly refreshing to me…I feel an impulse also already to jump into the half melted pond.

in Thoreau’s Journal:

We know too well what shall have for our Saturday’s dinner—but each days feast in Nature’s year is a surprise to us & adapted to our appetite & spirits—

She has arranged such an order of feasts as never tires–  Her motive is not economy but satisfaction.

in Thoreau’s Journal:

The eye must be firmly anchored to this earth which beholds birches and pines waving in the breeze in a certain light—a serene rippling light.

in Thoreau’s Journal:

I thank God that the cheapness which appears in time and the world—the trivialness of the whole scheme of things—is in my own cheap and trivial moment. 

I am time and the world. 

I assert no independence.

In me are summer and winter—village life and commercial routine—Pestilence and famine and refreshing breezes—joy and sadness—life and death….

He who does not borrow trouble does not lend it…

I wish to communicate those parts of my life which I would gladly live again…

It is hard to be a good citizen of the world in any great sense—but if we do render no interest or increase to mankind out of that talent God gave us—we can at least preserve the principal unimpaired.

in Thoreau’s Journal:

It is too cold to think of those signs of spring which I find recorded under this date last year.

in Thoreau’s Journal:

When I think what were the various sounds and notes, the migrations and works, and changes of fur and plumage which ushered in the spring and marked the other seasons of the year, I am reminded that this my life in nature, this particular round of natural phenomena which I call a year, is lamentably incomplete.  I listen to [a] concert in which so many parts are wanting. The whole civilized country is to some extent turned into a city, and I am that citizen whom I pity. Many of those animal migrations and other phenomena by which the Indians marked the season are no longer to be observed.  I seek acquaintance with Nature, ––to know her moods and manners….I am reassured and reminded that I am the heir of eternal inheritances which are inalienable, when I feel the warmth reflected from the sunny bank, and see the yellow sand and the reddish soil, and hear some dried leaves rustle and the trickling of melted snow in some sluiceway. The eternity which I detect in Nature I predicate of myself also. How many springs I have had this same experience! I am encouraged for I recognize this stead persistency and recovery of Nature as a quality of myself.
