"We abuse land because we see it as a commodity belonging to us. When we see land as a community to which we belong, we may begin to use it with love and respect." (p. xviii).
"The whole world is so greedy for more bathtubs that it has lost the stability necessary to build them, or even turn off the tap. Nothing could be more salutary at this stage than a little healthy contempt for a plethora of material blessings. [pgrph] Perhaps such a shift of values can be achieved by reappraising things unnatural, tame, and confined in terms of things natural, wild and free." (p. xix).
“The rough-leg [Hawk] has no opinion why grass grows, but he is well aware that snow melts in order that hawks may again catch mice. He came down out of the Arctic in the hope of thaws, for to him a thaw means freedom from want and fear.” (p. 5).
“Tufts of rabbit-hair bespeak the year’s first battles among amorous bucks. Further on I find a bloody spot, encircled by the arc of owl’s wings. To this rabbit the thaw brought freedom from want, but also a reckless abandonment of fear. The owl has reminded him that thoughts of spring are no substitute for caution." (p. 5).
“There are two spiritual dangers in not owning a farm. One is the danger of supposing that breakfast comes from the grocery, and the other that heat comes from the furnace.” (p. 6).
“Indeed, it is all to clear that every surviving oak is the product of either rabbit negligence or rabbit scarcity. Some day some patient botanist will draw a frequency curve of oak birth-years, and show that the curve humps every ten years, each hump originating from a low in the ten-year rabbit cycle. (A fauna and flora, by this very process of perpetual battle within and among species, achieve collective immortality).” (p. 7).
“We sensed that these two piles of sawdust were something more than wood: that they were the integrated transect of a century; that our saw was biting its way, stroke by stroke, decade by decade, into the chronology of a lifetime, written in concentric annual rings of oak.” (p. 10).
“Now our saw bites into the 1920’s, the Babbittian decade when everything grew bigger and better in heedlessness and arrogance - until 1929, when stock markets crumpled. If the oak heard them fall, its wood gives no sign.” (p. 10-11).
“We cut 1907, when a wandering lynx, looking in the wrong direction for the promised land, ended his career among the farms of Dane County.” (p. 12)
“Now our saw bites into the 1890’s, called gay by those whose eyes turn cityward than landward.” (p.13).
“Our saw now cuts the 1860’s, when thousands died to settle the question: Is the man-man community lightly to be dismembered? They settled it, but they did not see, nor do we yet see, that the same question applies to the man-land community.” (p.16-17).
“A cardinal, whistling spring to a thaw but later finding himself mistaken, can retrieve his error by resuming his winter silence. A chipmunk, emerging for a sunbath but finding a blizzard, has only to go back to bed. But a migrating goose, staking two hundred miles of black night on the chance of finding a hole in the lake, has no easy chance for retreat. His arrival carries the conviction of a prophet who has burned his bridges.” (p.19).
“I once knew an educated lady, banded by Phi Beta Kappa, who told me that she had never heard or seen the geese that twice a year proclaim the revolving seasons to her well-insulated roof. Is education possibly a process of trading awareness for things of lesser worth? The goose who trades his is soon a pile of feathers.” (p. 20).
“It is an irony of the history that the great powers should have discovered the unity of nations at Cairo in 1943. The geese of the world have had that notion for a longer time, and each March they stake their lives on its essential truth. [prgrph] In the beginning there was only the unity of the ice sheet. Then followed the unity of the March thaw and the northward hegira of the international geese. Every March since the Pleistocene, the geese have honked unity from the China Sea to the Siberian Steppe, from the Euphrates to Volga, from Nine to Murmansk, from Lincolnshire to Spitsbergen. Every March since the Pleistocene, the geese have honked unity from Currituck to Labrador, Matamuskeet to Ungava, Horseshoe Lake to Hudson’s Bay, Panhandle to Mackenzie, Sacramento to Yukon. [prgrph] ... And in this annual barter of food for light, and winter warmth for summer solitude, the whole continent receives a net profit of a wild poem dropped from the murky skies upon the muds of March.” (pp. 24-25).
But the average battle line between prairie and forest was about where it is now, and the net outcome of the battle was a draw. [prgrph] One reason for this was that there were allies that threw their support first to one side, then to the other. Thus rabbits and mice mowed down the prairie herbs in the summer, and in winter girdled any oak that survived the fires. Squirrels planted acorns in the fall, and ate them all the rest of the year. June beetles undermined the prairie sod in their grub stage, but defoliated the oaks in their adult stage. But for this geeing and hawing of allies, and hence of the victory, we should not have today that rich mosaic of prairie and forest soils which looks so decorative on the map.” (pp. 29 and 31).
“In the 1840’s a new animal, the settler, intervened in the prairie battle. He didn’t mean to, he just plowed enough fields to deprive the prairie of its immemorial ally: fire. Seedling oaks forthwith romped over the grasslands in legions, and what had been the prairie region became a region of woodlot farms. If you doubt this story, go count rings on any set of stumps on any “ridge” woodlot in southwest Wisconsin. All trees except the oldest veterans date back to the 1850’s and the 1860’s, and this is when fires ceased on the prairie.” (p. 31).
“There he sits; his whole being says it’s your next move to absent yourself from his domain. The county records may allege that you own this pasture, but the [upland] plover airily rules out such trivial legalities. He has just flown 4000 miles to reassert the title he got from the Indians, and until the young plovers are a-wing, this pasture is his, and none may trespass without his protest.” (p. 37).
“I sit in happy meditation on my rock, pondering while my line dries again, upon the ways of trout and men. How like fish we are: ready, nay eager, to seize upon whatever new thing some wind of circumstance shakes down upon the river of time! And how we rue our haste, finding the gilded morsel to contain a hook. Even so, I think there is some virtue in eagerness, whether its object prove true or false.” (p. 42).
“Expanses unknown to deed or map are known to every dawn, and solitude, supposed no longer to exist in my county, extends on every hand as far as the dew can reach.” (p. 44).
“I can feel the sun now. The bird-chorus has run out of breath. The far clank of cowbells bespeaks a herd ambling to pasture. A tractor roars warning that my neighbor is astir. The world has shrunk to those mean dimensions known to county clerks.” (p.47).
“Hereftofore unreachable by scythe or mower, this yard-square relic of original Wisconsin gives birth, each July to a man high stalk of compass plant or cutleaf Silphium, spangled with saucer-sized yellow blooms resembling sunflowers. It is the sole remnant of this plant along this highway, and perhaps the sole remnant in the western half of our county. What a thousand acres of Silphiums looked like when they tickled the bellies of the buffalo is a question never again to be answered, and perhaps not even asked.” (p. 49).
“When I passed this graveyard again on 3 August, the fence had been removed by a road crew, and the Silphium cut. It is easy now to predict the future; for a few years my Silphium will try in vain to rise above the mowing machine, and then it will die. With it will die the prairie epoch.” (p.49).
“If I were to tell a preacher of the adjoining church that the road crew has been burning history books in his cemetery, under the guise of mowing weeds, he would be amazed and uncomprehending. How could a weed be a book?” (p. 50).
“There is a peculiar virtue in the music of elusive birds. Songsters that sing from the top-most boughs are easily seen and as easily forgotten; they have the mediocrity of the obvious. What one remembers is the invisible hermit thrush pouring silver chords from impenetrable shadows;the soaring crane trumpeting from behind a cloud; the prairie chicken booming from the mists of nowhere; the quails Ave Maria in the hush of dawn.” (p. 57).
“Early risers feel at ease with each other, perhaps because, unlike those who sleep late, they are given to understatement of their own achievements. Orion, the most widely traveled, says literally nothing. The coffee pot, from its soft gurgle, underclaims the virtues of what simmers within. The owl, in his trisyllabic commentary, plays down the story of the night’s murders. The goose on the bar, rising briefly to a point of order in some inaudible anserine debate, lets fall no hint that he speaks with the authority of all the far hills and the sea.” (p.63).
“My dog, by the way, thinks I have much to learn about partridges, and, being a professional naturalist, I agree. He persists in tutoring me, with the calm patience of a professor of logic, in the art of drawing deductions from an educated nose. I delight in seeing him deduce a conclusion, in the form of a point, from data that are obvious to him, but speculative to my unaided eye. Perhaps he hopes his dull pupil will one day learn to smell.” (p. 67).
“The Lord giveth, and the Lord taketh away, but He is no longer the only one to do so. When some remote ancestor of ours invented the shovel, he became a giver: he could plant a tree. And when the axe was invented, he became a taker: he could chop it down. Whoever owns land has thus assumed, whether he knows it or not, the divine functions of creating and destroying plants.” (p.72)
“To me an ancient cottonwood is the greatest of trees because in his youth he shaded the buffalo and wore a halo of pigeons, and I like a young cottonwood because he may some day become ancient. But the farmer’s wife (and hence the farmer) despises all cottonwoods because in June the female tree clogs the screens with cotton. The modern dogma is comfort at any cost.” (p. 76).
“The pine’s new year begins in May, when the terminal bud becomes “the candle.” Whoever coined that name for the new growth had subtlety in his soul. “The candle” sounds like a platitudinous reference to obvious facts: the new shoot is waxy, upright, brittle. But he who lives with pines knows that the candle has a deeper meaning, for at its tip burns the eternal flame that lights a path into the future.” (p. 87.)
“Each species of pine has its own constitution, which prescribes a term of office for needles appropriate to its way of life. Thus the white pine retains its needles for a year and a half; the red and jackpines for two years and a half. Incoming needles take office in June, and outgoing needles write farewell addresses in October. All write the same thing, in the same tawny yellow ink, which by November turns brown. Then the needles fall, and are filed in the duff to enrich the wisdom of the stand. It is this accumulated wisdom that hushes the footsteps of whoever walks under pines.” (p. 92).
That whimsical fellow called Evolution, having enlarged the dinosaur until he tripped over his own toes, tried shrinking the chickadee until he was just too big to be snapped up by flycatchers as an insect, and just too little to be pursued by hawks and owls as meat. Then he regarded his handiwork and laughed. Everyone laughs at so small a bundle of large enthusiasms.” (p. 96).
“Books on nature seldom mention wind; they are written behind stoves.” (p.97).
“Our ability to perceive quality in nature begins, as in art, with the pretty. It expands through successive stages of the beautiful to values as yet uncaptured by language. The quality of cranes lies, I think, in this higher gamut, as yet beyond the reach of words.” (p. 102).
“Thus always does history, whether of marsh or market place, end in paradox. The ultimate value in these marshes is wildness, and the crane is wildness incarnate. But all conservation of wildness is self-defeating, for to cherish we must see and fondle, and when enough have seen and fondled, there is no wilderness left to cherish.” (pp. 107-108).
“X had marked time in the limestone ledge since the Paleozoic seas covered the land. Time, to an atom locked in a rock, does not pass. [prgrph] The break came when a bur-oak root nosed down a crack and began prying and sucking. In the flash of a century the rock decayed, and X was pulled out and up into the world of living things. He helped build a flower, which became an acorn, which fattened a deer, which fed an Indian, all in a single year. [prgrph] From his berth in the Indian’s bones, X joined again in chase and flight, feast and famine, hope and fear. He felt these things as changes in the little chemical pushes and pulls that tug timelessly at every atom. When the Indian took his leave of the prairie, X moldered briefly underground, only to embark on a second trip through the bloodstream of the land.” (p. 111).
“It is a century now since Darwin gave us the first glimpse of the origin of species. We now know what was unknown to all the preceding caravan of generations: that men are only fellow-voyagers with other creatures in the odyssey of evolution. This new knowledge should have given us, by this time, a sense of kinship with fellow creatures; a wish to live and let live; a sense of wonder over the magnitude and duration of the biotic enterprise. [prgrph] Above all we should, in the century since Darwin, have come to know that man, while now captain of the adventuring ship, is hardly the sole object of its quest, and that his prior assumptions to this effect arose from the simple necessity of whistling in the dark.” (pp. 116-117).
“For one species to mourn the death of another is a new thing under the sun. The Cro-Magnon who slew the last mammoth thought only of steaks. The sportsman who shot the last pigeon though only of his prowess. The sailor who clubbed the last auk though of nothing at all. But we, who have lost our pigeons, mourn the loss. Had the funeral been ours, the pigeons would have hardly have mourned us. In this fact, rather than in Mr. Du Pont’s nylons or Mr. Vannevar Bush’s bombs, lies objective evidence of our superiority over the beasts.” (p. 117).
“When I call to mind my earliest impressions, I wonder whether the process ordinarily referred to as growing up is not actually a process of growing down; whether experience, so much touted among adults as the thing children lack, is not actually a progressive dilution of the essentials by the trivialities of living. This much at least is sure: my earliest impressions of wildlife and its pursuit retain a vivid sharpness of form, color, and atmosphere that half a century of professional wildlife experience has failed to obliterate or to improve upon.” (p. 128).
“Only the mountain has lived long enough to listen objectively to the howl of a wolf.” (p. 137).
“In those days we had never heard of passing up a chance to kill a wolf. In a second we were pumping lead into the pack, but with more excitement than accuracy: how to aim a steep downhill shot is always confusing. While our rifles were empty, the old wolf was down, and a pup was dragging a leg into impassable slide-rocks. [prgrph] We reached the old wolf in time to watch a fierce green fire dying in her eyes. I realized then, and have known ever since, that there was something new to me in those eyes- something known only to her and to the mountain. I was young then, and full of trigger-itch; I thought that because fewer wolves meant more deer, that no wolves would mean hunter’s paradise. But after seeing the green fire die, I sensed that neither the wolf nor the mountain agreed with such a view.” (p. 138-139).
“I now suspect that just as a deer herd lives in mortal fear of its wolves, so does a mountain live in mortal fear of its deer. And perhaps with better cause, for while a buck pulled down by wolves can be replaced in two or three years, a range pulled down by too many deer may fail of replacement in as many decades. [prgrph] So also with cows. The cowman who cleans his range of wolves does not realize that he is taking over the wolf’s job of trimming the herd to fit the range. He has not learned to think like a mountain. Hence we have dustbowls, and rivers washing the future into the sea.” (p 140).
“The government trapper who took the grizzly knew he had made Escudilla safe for cows. He did not know he had toppled the spire off an edifice a-building since the morning stars sang together. [prgrph] The bureau chief who sent the trapper was a biologist versed in the architecture of evolution, but he did not know that spires might be as important as cows. He did not foresee that within two decades the cow country would become tourist country, and have greater need of bears than of beefsteaks. [prgrph] The Congressmen who voted money to clear the ranges of bears were the sons of the pioneers. They acclaimed the superior virtues of the frontiersman, but they strove with might and main to make an end to the frontier.” (pp. 144-145).
“Escudilla still hangs on the horizon, but when you see it you no longer think of bear. It’s only a mountain now.” (p. 145).
“ The physics of beauty is one department of natural science still in the Dark Ages. Not even the manipulators of bent space have tried to solve its equations. Everybody knows, for example, that the autumn landscape in the north woods is the land, plus a red maple, plus a ruffed grouse. In terms of conventional physics, the grouse represents only a millionth of either the mass or the energy of an acre. Yet subtract the grouse and the whole thing is dead. An enormous amount of some kind of motive power has been lost.” (p. 146).
“We always examined these deer trails, hoping to find signs of el tigre. [prgrph] We saw neither hide nor hair of him, but his personality pervaded the wilderness; no living beast forgot his potential presence, for the price of unwariness was death. No deer rounded a bush, or stopped to nibble pods under a mesquite tree, without a premonitory sniff for el tigre. No campfire died without talk of him. No dog curled up for the night, save at his master’s feet, he needed no telling that the king of cats still ruled the night; that those massive paws could fell an ox, those jaws shear off bones like a guillotine. [prgrph] By this time the Delta has probably been made safe for cows, and forever dull for adventuring hunters. Freedom from fear has arrived, but a glory has departed from the green lagoons.” (pp. 151-152).
“This song of the waters is audible to every ear, but there is other music in these hills, by no means audible to all. To hear even a few notes of it you must first live here for a long time, and you must know the speech of hills and rivers. Then on a still night, when the campfire is low and the Pleiades have climbed over rimrocks, sit quietly and listen for a wolf to howl, and think hard of everything you have seen and tried to understand. Then you may hear it- a vast pulsing harmony- its score inscribed on a thousand hills, its notes the lives and deaths of plants and animals, its rhythms spanning the seconds and the centuries.” (p. 158).
“Science contributes moral as well as material blessings to the world. Its great moral contribution is objectivity, or the scientific point of view. This means doubting everything except facts; it means hewing to the facts, let the chips fall where they may. One of the facts hewn to by science is that every river needs more people, and all people need more inventions, and hence more science; the good life depends on the indefinite extension of this chain of logic. That the good life on any river may likewise depend on the perception of its music, and the preservation of some music to perceive, is a form of doubt not yet entertained by science.” (p. 163).

"The mouse is a sober citizen who knows that grass grows in order that mice may store it as underground haystacks, and that snow falls in order that mice may build subways from stack to stack: supply, demand, and transport all neatly organized. To the mouse, snow means freedom from want and fear.” (p. 4).
