in Thoreau’s Journal:

The progress of the season is indescribable…Perhaps the sound of the locust expresses the season as well as anything.  The farmers say the abundance of the grass depends on wet in June.  I might make a separate season of those days when the locust is heard.  That is our torrid zone.

in Thoreau’s Journal:

It is far more independent to travel on foot….

in Thoreau’s Journal:

The last sunrise I witnessed seems to outshine the splendor of all preceding ones, and I was convinced that it behoved man to dawn as freshly, and with equal promise and steadiness advance into the career of life, with as lofty and serene a countenance to move onward through his midday to a yet fairer and more promising setting….We will have a dawn––and noon––and serene sunset in ourselves.

in Thoreau’s Journal:

Nature is reported not by him who goes forth consciously as an observer, but in the fullness of life. 

in Thoreau’s Journal:

A young man in Sudbury told me he had heard woodchucks whistle.

in Thoreau’s Journal:

The blue flag (Iris versicolor) enlivens the meadow. The lark sings at sundown off in the meadow. It is a note which belongs to a New England summer evening. Though so late, I hear the summer hum of a bee in the grass, as I am on my way to the river behind Hubbard’s to bathe. After hoeing in a dusty garden all this warm afternoon, —so warm that the baker says he never knew the like and expects to find his horses dead in the stable when he gets home, —it is very grateful to wend one’s way at evening to some pure and cool stream and bathe therein.

in Thoreau’s Journal:

How interesting the bud’s progress from the water to the air! So many of these stems are leaf-bearing, and so many flower-bearing. Then consider how defended these plants against drought, at the bottom of the water, at most their leaves and flowers floating on its surface. How much mud and water are required to support their vitality! It is pleasant to remember those quiet Sabbath mornings by remote stagnant rivers and ponds, when pure white water-lilies, just expanded, not yet infested by insects, float on the waveless water and perfume the atmosphere. Nature never appears more serene and innocent and fragrant. A hundred white lilies, open to the sun, rest on the surface smooth as oil amid their pads, while devil’s-needles are glancing over them.

in Thoreau’s Journal:

Pontederia to-morrow.

Pontederia to-morrow.

in Thoreau’s Journal:

I still perceive that ambrosial sweetness from the meadows in some places. Give me the strong, rank scent of ferns in the spring for vigor; just blossoming late in the spring. A healthy and refined nature would always derive pleasure from the landscape. As long as the bodily vigor lasts, man sympathizes with nature.

in Thoreau’s Journal:

Just so much beauty and virtue as there is in the world, and just so much ugliness and vice, you see expressed in flowers.  Each human being has his flower which expresses his character.  In them nothing is concealed, but everything published. 

in Thoreau’s Journal

There is a flower for every mood of the mind.  

in Thoreau’s Journal:

The Linnaea borealis [twin-flower] just going out of bloom.  I should have found it long ago. Its leaves densely cover the ground.

in Thoreau’s Journal:

I cannot see the bottom of the sky, because I cannot see to the bottom of myself. It is the symbol of my own infinity. My eye penetrates as far into the ether as that depth is inward from which my contemporary thought springs.

Not by constraint or severity shall you have access to true wisdom, but by abandonment, and childlike mirthfulness. If you would know aught, be gay before it.

in Thoreau’s Journal:

My pulse must beat with Nature. 

in Thoreau’s Journal: 

Nature has looked uncommonly bare & dry to me for a day or two. With our senses applied to the surrounding world we are reading our own physical & corresponding moral revolutions. Nature was so shallow all at once I did not know what had attracted me all my life. I was therefore encouraged when going through a field this evening, I was unexpectedly struck with the beauty of an apple tree –– the perception of beauty is a moral test….

in Thoreau’s Journal:

Upland haying begun. Or beginning–

in Thoreau’s Journal:

What subtle differences between one season and another! The warmest weather has, perchance, arrived and the longest days, but not the driest. When I remember gathering ripe blackberries on sandy fields or stones by the roadside, the very berries warmed by the sun, I am convinced of this. The seasons admit of infinite degrees in their revolutions.  Found one of the purple orchises in an open meadow.

in Thoreau’s Journal:

I should be pleased to meet man in the woods.

I wish he were to be encountered like wild caribous and moose.

I am startled when I consider how little I am actually concerned about the things I write in my journal.

in Thoreau’s Journal:

There are some fine large clusters of lambskill close to the shore of Walden and in the Peak fronting the south–– They are early there & large ap. both on account of the warmth & the vicinity of the water –– These flowers are in perfect cylinders sometimes 6 inches long by 2 wide––and 3 such raying out or upward from one centre i.e. 3 branches clustered together.
