On the 29th of April,as I was fishing from the bank of the river near the Nine-Acre-Corner bridge,standing on the quaking grass and willow roots,where the muskrats lurk,I heard a singular rattling sound,somewhat like that of the sticks which boys play with their fingers,when,looking up,I observed a very slight and graceful hawk,like a nighthawk,alternately soaring like a ripple and tumbling a rod or two over and over,showing the under side of its wings,which gleamed like a satin ribbon in the sun,or like the pearly inside of a shell.This sight reminded me of falconry and what nobleness and poetry are associated with that sport.The merlin it seemed to me it might be called;but I care not for its name.It was the most ethereal flight I had ever witnessed.It did not simply flutter like a butterfly,nor soar like the larger hawks,but it sported with proud reliance in the fields of air;mounting again and again with its strange chuckle,it repeated its free and beautiful fall,turning over and over like a kite,and then recovering from its lofty tumbling,as if it had never set its foot on terra firma.It appeared to have no companion in the universe,-sporting there alone,-and to need none but the morning and the ether with which it played.It was not lonely,but made all the earth lonely beneath it.Where was the parent which hatched it,its kindred,and its father in the heavens?The tenant of the air,it seemed related to the earth but by an egg hatched some time in the crevice of a crag;-or was its native nest made in the angle of a cloud,woven of the rainbow's trimmings and the sunset sky,and lined with some soft midsummer haze caught up from earth?Its eyry now some cliffy cloud.
Beside this I got a rare mess of golden and silver and bright cupreous fishes,which looked like a string of jewels.Ah!I have penetrated to those meadows on the morning of many a first spring day,jumping from hummock to hummock,from willow root to willow root,when the wild river valley and the woods were bathed in so pure and bright a light as would have waked the dead,if they had been slumbering in their graves,as some suppose.There needs no stronger proof of immortality.All things must live in such a light.O Death,where was thy sting?O Grave,where was thy victory,then?
Our village life would stagnate if it were not for the unexplored forests and meadows which surround it.We need the tonic of wildness,-to wade sometimes in marshes where the bittern and the meadow-hen lurk,and hear the booming of the snipe;to smell the whispering sedge where only some wilder and more solitary fowl builds her nest,and the mink crawls with its belly close to the ground.At the same time that we are earnest to explore and learn all things,we require that all things be mysterious and unexplorable,that land and sea be infinitely wild,unsurveyed and unfathomed by us because unfathomable.We can never have enough of nature.We must be refreshed by the sight of inexhaustible vigor,vast and titanic features,the sea-coast with its wrecks,the wilderness with its living and its decaying trees,the thunder-cloud,and the rain which lasts three weeks and produces freshets.We need to witness our own limits transgressed,and some life pasturing freely where we never wander.We are cheered when we observe the vulture feeding on the carrion which disgusts and disheartens us,and deriving health and strength from the repast.There was a dead horse in the hollow by the path to my house,which compelled me sometimes to go out of my way,especially in the night when the air was heavy,but the assurance it gave me of the strong appetite and inviolable health of Nature was my compensation for this.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;and that sometimes it has rained flesh and blood!With the liability to accident,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 hear to be stereotyped.
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 phbe 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 wings 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 and the stones and rotten wood along the shore,so that you could have collected a barrelful.This is the “sulphur showers”we hear of.Even in Calidas'drama of Sacontala,we read of “rills dyed yellow with the golden dust of the lotus.”And so the seasons went rolling on into summer,as one rambles into higher and higher grass.
Thus was my first year's life in the woods completed;and the second year was similar to it.I finally left Walden September 6th,1847.
