"One attraction in coming to the woods to live was that I should have leisure and opportunity to see the Spring come in. The ice in the pond at length begins to be honeycombed, and I can set my heel in it as I walk. Fogs and rains and warmer suns are gradually melting the snow; the days have grown sensibly longer; and I see how I shall get through the winter without adding to my woodpile, for large fires are no longer necessary. I am on the alert for the first signs of spring, to hear the chance note of some arriving bird, or the striped squirrel's chirp, for his stores must be now nearly exhausted, or see the woodchuck venture out of his winter quarters. ...
When the ground was partially bare of snow, and a few warm days had dried its surface somewhat, it was pleasant to compare the first tender signs of the infant year just peeping forth with the stately beauty of the withered vegetation which had withstood the winter, -- life-everlasting, goldenrods, pinweeds, and graceful wild grasses ...
Walden is melting apace. There is a canal two rods wide along the northerly and westerly sides, and wider still at the east end. A great field of ice has cracked off from the main body. I hear a song sparrow singing from the bushes on the shore, -- olit, olit, olit, -- chip, chip, chip, che char, -- che wiss, wiss, wiss. He too is helping to crack it. ... It is glorious to behold this ribbon of water sparkling in the sun, the bare face of the pond full of glee and youth, as if it spoke the joy of the fishes within it ... Walden was dead and is alive again. ... You may tell by looking at any twig of the forest, ay, at your very wood-pile, whether its winter is past or not. As it grew darker, I was startled by the honking of geese flying low over the woods, like weary travellers getting in late from Southern lakes, and indulging at last in unrestrained complaint and mutual consolation. ...
Early in May, the oaks, hickories, maples, and other trees, just putting out amidst the pine woods around the pond, imparted a brightness like sunshine to the landscape, especially in cloudy days, as if the sun were breaking through mists and shining faintly on the hillsides here and there. On the third or fourth of May I saw a loon in the pond, and during the first week of the month I heard the whip-poor-will, the brown thrasher, the veery, the wood pewee, the chewink, and other birds. I had heard the wood thrush long before. The phoebe had already come once more and looked in at my door and window, to see if my house was cavern-like enough for her, sustaining herself on humming winds with clinched talons, as if she held by the air, while she surveyed the premises. The sulphur-like pollen of the pitch pine soon covered the pond ... This is the "sulphur showers" ... And so the seasons went rolling on into summer, as one rambles into higher and higher grass."

"I love to see that Nature is so rife with life that myriads can be afforded to be sacrificed and suffered to prey on one another; that tender organizations can be so serenely squashed out of existence like pulp-tadpoles which herons gobble up, and tortoises and toads run over in the road; ... we must see how little account is to be made of it. The impression made on a wise man is that of universal innocence. Poison is not poisonous after all, nor are any wounds fatal. Compassion is a very untenable ground. It must be expeditious. Its pleadings will not bear to be stereotyped."
