Northwest passage : the great Columbia River by William Dietrich Simon & Schuster, Incorporated, New York, New York State, 1995
"When Lewis and Clark reached the Columbia River in 1805, they found a roaring and unruly river with a treacherous mouth and confusing course, boasting salmon runs without equal in the world. William Dietrich, Pulitzer Prize-winning reporter and author of The Final Forest, reveals the heroic stories, triumphant engineering, and disturbing taming of this powerful, beautiful river. Northwest Passage is a masterwork of history, geography, and science, a sweeping overview of the transformation of the Columbia from its geologic origins and aboriginal inhabitants to its pioneers, settlers, dam builders, farmers, and contemporary native Americans." "The Columbia is the second largest river, by volume, in the U.S. and the largest on the west coast of the Western Hemisphere. Its terrain varies from rain forests with more than 100 inches of precipitation a year to desert with as little as 5 inches per year. It was once the most inexhaustible of rivers with as many as 16 million fish pushing up its 1,200-mile length each year to spawn and die in its hundreds of tributaries, a run supporting one of the most populous and complex native cultures on the continent. Before the European discovery of the Columbia River, dreaming merchants and intrepid explorers risked their lives and their money to find the entrance to and navigate the wildly unpredictable course of this "Great River of the West."" "Native Americans clung to the Columbia as the root of their culture, colonizers came in search of productive land and an efficient trade route, and industrialists seeking energy transformed the region's wild beauty." "The Columbia of today is a product of its yesterdays. It is docile, run by engineers and turned on and off by valves with fourteen major dams on the river and more than 500 in its basin. The obstacle course of falls, boulders, whirlpools, and floods has been harnessed and provides 70 percent of the Northwest's energy. Yet these dams, plus pollution, irrigation, and growth, have caused half of the region's streams to be blocked and 98 percent of the wild salmon to disappear. In 1991, just four Snake River sockeye salmon survived the 970-mile gauntlet of nets and dams to reach spawning beds in Idaho's Sawtooth Mountains, 6,500 feet high. Environmentalists have named the Columbia one of the nation's most imperiled rivers." "Northwest Passage is not only about the natural and human history of the river but also about how people changed the Columbia and were in turn changed by it. What happens to the Columbia, after all, is what happens to us."--BOOK JACKET

When Lewis and Clark reached the Columbia River in 1805, they found a roaring and unruly river with a treacherous mouth and confusing course, boasting salmon runs without equal in the world. William Dietrich, Pulitzer Prize-winning reporter and author of The Final Forest, reveals the heroic stories, triumphant engineering, and disturbing taming of this powerful, beautiful river. Northwest Passage is a masterwork of history, geography, and science, a sweeping overview of the transformation of the Columbia from its geologic origins and aboriginal inhabitants to its pioneers, settlers, dam builders, farmers, and contemporary native Americans.

River of the west : a chronicle of the Columbia Clark, Robert HarperCollins West, 1st ed., [San Francisco, Calif.], California, 1995
The Columbia River is the great river of both the American West and of the American imagination. From the glacial floods that began to shape it twelve thousand years ago to its discovery, conquest, and colonization by the English, Spanish, and Americans, the river's story encompasses not only the full range of American history but a geography of myth, hope, and tragedy: the impact of conquest on the native peoples; the idea of a United States reaching to the Pacific; the material and spiritual quests of European adventurers, New England missionaries, and emigrants from the drought-ridden plains of the Midwest; and hydropowered New Deal dreams of peace and prosperity. In River of the West, the Columbia unfolds itself in stories of the people who lived and died on its shores; "discovered" and claimed it for their country; or depended on its dam-generated power or bountiful salmon. Portraits of the shaman Smohalla, leader of the "renegade" Indians who refused to settle on the reservations, and Christian missionary Narcissa Whitman, who was mutilated and murdered by the tribe she had come to redeem (a tribe nearly destroyed by the diseases brought by white settlers), plumb the perspectives of the Indigenous river peoples, the dreams of explorers and settlers, and the drama that resulted when the two met. Detailing Franklin Delano Roosevelt's stirring speeches urging the construction of the Grand Coulee and Bonneville dams, Clark evokes the "hydro-socialism" that brought dust-bowl refugees and Woody Guthrie to the lush Northwest and went on to create boomtowns as the dams powered a huge portion of the nation's World War II manufacturing effort. And, through the accounts of five imprisoned Indian fishermen, Clark reveals the tragic story of how the dams made salmon extinct on two-thirds of the Columbia and flooded ancient fishing grounds, stripping Indians of their livelihood and traditional way of life. Dramatic, often profound, and always riveting, River of the West is an unforgettable portrait of the West's greatest waterway. Providing material and spiritual sustenance for at least two dozen native river peoples; the impetus for countless expeditions by explorers - and exploiters - from around the world; central to the national visions of both Thomas Jefferson and Franklin Delano Roosevelt; the subject of more than twenty songs by Woody Guthrie; and the site of a "salmonscam" that pitted the U.S. government against traditional Yakima fishermen, the Columbia - the mythic, eternal river of the American West - has many stories to tell

Distance Education : An Annotated Bibliography Terry Ann Mood (Leopold) Libraries Unlimited, Inc., P.O. Box 6633, Englewood, CO 80155-6633 ($27.50), Bloomsbury USA, Englewood, Colo, 1995
This annotated bibliography emphasizes the pedagogical concerns of distance education with a focus on teachers, students, and administrators. Chapter 1 begins with the history of distance education and correspondence education; histories of specific institutions; and histories of television in the classroom. Chapter 2 covers the philosophy of distance education with the following topics: the definition of distance education; the difference between distance education and traditional education, and applicable learning theories; student responsibilities; and the purpose of distance education to extend educational opportunities. Administrative questions of cost; organizational structure; methods of communication with students; and evaluation procedures for both students and programs are discussed in chapter 3. Chapters 4 and 5 focus on issues of interest to teachers and to students. Highlights for teachers include preparing course materials, presenting lecture material on television, engaging off-site students actively in a class; and for students, the possibility of maximizing their learning from distance education. Chapter 6 explores distance education in non-academic settings, particularly in the military and in industry. Chapter 7 examines the efforts of many countries to provide distance education. Books are cross-referenced from one chapter to another. Two-hundred and ninety-seven sources are provided. Appendices list periodicals that cover the field of distance education and electronic sources (online journals or discussion groups) devoted to the field. (AEF)

The underwater crime scene : underwater crime investigative techniques Becker, Ronald F. Charles C. Thomas Publisher, Limited, Charles C Thomas Publisher, Springfield, 1995
Since the early 1960s, a group of dedicated archaeologists, with a love for the sea and scuba diving, has given birth, nourished, and raised underwater investigation to a science. Utilizing the same type of concepts and techniques as field archaeologists, including painstaking application of patience, scientific method, measurement, photography, sketches, and recovery, they have been able to retrieve and reconstruct ancient vessels and their cargoes. It is the purpose of this book to bring together the science of marine archaeology to the needs of police agencies that have the responsibility for providing law enforcement on waterways. Much evidence is lost, unrecognized, or mishandled and rendered unusable at time of trial because of improper handling during the underwater recovery process. This text provides the scientific alternative to what is presently being done. Topics include legal liability and the underwater process, the underwater crime scene, the underwater recovery team, boat searches and patterns, temporal and geographical plotting of evidence, underwater excavation, handling evidence, medicolegal aspects of underwater death, and using recovered evidence in the courtroom

The Organic machine : [the remaking of the Columbia river White, Richard, Richard White Hill & Wang Pub, Critical issue, First paperback edition, New York, 1996
gt;gt;The Organic Machinegt;gt;gt;gt;gt;gt;CHAPTER 1gt;gt;gt;gt;Knowing Nature through Labor: Energy, Salmon Society on the Columbiagt;gt;gt;gt;gt;Igt;gt;gt;gt;Tgt;he world is in motion. Tectonic plates drift across a spinning planet. Mountains are lifted up and eroded to the sea. Glaciers advance and retreat. All natural features move, but few natural features move so obviously as rivers. Our metaphors for rivers are all metaphors of movement: they run and roll and flow.gt;gt;Like us, rivers work. They absorb and emit energy; they rearrange the world. The Columbia has been working for millennia. During the Miocene, volcanic eruptions deposited layers of basalt across the Columbia Plain. The upper Columbia cut a gutter through which it ran along the margins of the basaltic flow. At Wenatchee the rise of the Horse Heaven anticline caused the river to cut into the basalt; it drained into the Pasco basin, the lowest point on its route east of the Cascades, and emerged from the basin at the Wallula Gap. During the Pleistocene the collapse of an ice dam holding glacial Lake Missoula created the largest known freshwater flood in the earth's history. It was an afternoon's work for one of the Missoula floods to create the Grand Coulee and other rock channels of the Channeled Scablands. In those few hours it accomplished work that it would have taken the Mississippi three hundred years at full flood to duplicate. The flood rushed into the Columbia channel and finally slowed enough to create the "Portland Delta" of the Willamette lowlands. Since then ice dams have blocked the Columbia's bed, temporarily spilling the river into the Grand Coulee;mountains have slid into it, and humans have dammed it. All these changes have left work for the river to do.gt;gt;For much of human history, work and energy have linked humans and rivers, humans and nature. But today, except when disaster strikes, when a hurricane hits, or earthquakes topple our creations, or when a river unexpectedly rises and sweeps away the results of our effort and labor, we forget the awesome power--the energy--of nature. There is little in our day-to-day life to preserve the connection. Machines do most of our work; we disparage physical labor and laborers. The link between our work and nature's work has weakened. We no longer understand the world through labor. Once the energy of the Columbia River was felt in human bones and sinews; human beings knew the river through the work the river demanded of them.gt;gt;Early-nineteenth-century accounts of the Columbia can be read in many ways, but they are certainly all accounts of work, sweat, exhaustion, and fear. The men of the early nineteenth century who wrote the Lewis and Clark journals and the accounts of the Astorian trading post, the North West Company and Hudson's Bay Company, knew the energy of the river. They had to expend their own energy to move up, down, and across it. Alexander Ross's marvelous gt;Adventures of the First Settlers on the Oregon or Columbia Rivergt;, a narrative of the arrival of the Astorians and the establishment of the fur-trading outpost of Astoria in 1811, can serve as a primer on the Columbia as an energy system during a time when human beings--Indian and white--had only the wind and the strength of their own muscles to match against the powerful currents of the river.gt;gt;"The mouth of the Columbia River," Ross wrote, "is remarkable for its sand bars and high surf at all seasons, but more particularly in the spring and fall, during the equinoctial gales." The shoals and sandbars at the Columbia's mouth are relicts of its work and energy. In areas without strong tidal action a river deposits the load it carries to its mouth as a delta, but the Columbia emerges into the Pacific in an area of strong tides and persistent storms.gt;gt;The river's current and the tides battle at the Columbia's mouth and prevent the formation of a delta. At full flood, Captain Charles Wilkes wrote in 1841, one could "scarcely have an idea of its flow how swollen it is, and to see the huge trunks of thick gigantic forests borne like chips on its bosom astonishes one." During ebb tides the river pushes itsfreshwater out many miles into the sea. The tides, in turn, are felt as high as 140 miles upriver when the Columbia's water level is at its fall and winter low. This pushing and pulling produces a set of sandbars and islands at the river's mouth. Ocean currents and tides force themselves against the bars with "huge waves and foaming breakers." The result is "a white foaming sheet for many miles, both south and north of the mouth of the river, forming as it were an impracticable barrier to the entrance, and threatening with instant destruction everything that comes near it." To enter the river, ships, powered only by wind and aided by the tide, or boats and canoes powered by human muscle, had to pass through this barrier.gt;gt;During the Astorians' own terrible entry into the Columbia in 1811, they sent out small boats to find a channel into the river for their ship, the Tonquin. In Ross's dramatic telling, the Astorians watched as the Tonquin's first officer, Ebenezer Fox, protested to Captain Jonathan Thorn that the seas were "too high for any boat to live in." In reply Thorn only taunted Fox: "Mr. Fox, if you are afraid of water, you should have remained at Boston." Fox's uncle had died at the mouth of the Columbia. In despair Fox announced that he was "going to lay my bones with his." He shook hands with the Astorians and, getting into the boat, shouted, "Farewell, my friends ... we will perhaps meet again in the next world." Fox's crew was inexperienced and the sea violent. Not one hundred yards from the ship the boat became unmanageable. The waves hit the craft broadside, whirled it like a top, and "tossing on the crest of a huge wave, [it would] sink again for a time and disappear all together." Fox hoisted a flag to signal his distress, but the gt;Tonquingt; turned about, and they "saw the ill-fated boat no more."gt;gt;Ross himself took part in a second attempt, and he discovered more immediately the experience of pitting human energy against the energy focused at the mouth of the river. As they first approached the bar with its "terrific chain of breakers," the "fearful suction or current" gripped the boat before they realized what had happened. The second officer, Mr. Mumford, called for them to match their strength against that of the river and sea: "Let us turn back, and pull for your lives. Pull hard, or you are all dead men." They pulled hard and survived, but this attempt to enter the river and two more failed. The gt;Tonquingt; eventually made the passage across the bar, but only after eight men had died.gt;gt;In their ordeal at the bar the Astorians had confronted storms, sandbars,and currents; men had labored and died. But wave, water, and wind--and human labor--can be represented in ways beyond the immediacy of actual experience. We can abstract them to a single entity: energy. There is a physics to the gt;Tonquin'sgt; drama at the river's mouth, and it leads outward beyond the earth to the sun and the moon. Lunar gravitation causes the tides, but virtually all the rest of the energy manifest at the Columbia's mouth originates in the sun. The sun, in effect, provides fuel for a giant atmospheric heat engine which evaporates water from the oceans and produces winds that move the moisture over land. As the clouds cool, the moisture falls as rain. Without solar energy to move the water inland and uphill, rivers would never begin; without gravity to propel the water downhill back toward the ocean, rivers would never flow. In a real sense the Columbia begins everywhere that the rain that eventually enters it falls. The Columbia gathers its water from an area of 258,200 square miles, but not all that water finds its way into the river as it flows 1,214 miles to the sea. Some of it is lost through transpiration and use in plant tissues; some is lost through evaporation.gt;gt;Physicists define energy as the capacity to do work. Work, in turn, is the product of a force acting on a body and the distance the body is moved in the direction of the force. Push a large rock and you are expending energy and doing work; the amount of each depends on how large the rock and how far you push it. The weight and flow of water produce the energy that allows rivers to do the work of moving rock and soil: the greater the volume of water in the river and the steeper the gradient of its bed, the greater its potential energy.gt;gt;In fact, however, neither the Columbia nor any other river realizes all of its potential energy as work. Indeed, only about 2 percent of the river's potential energy results in work: the erosion, transportation, and deposition of matter. About 98 percent of the river's kinetic energy is expended in friction as the moving water rubs against itself, its bed, and its bank. This energy is dissipated as heat within the river.gt;gt;Engineers can measure the potential energy and the kinetic energy of the Columbia with some precision, but early voyagers like Ross recognized the power--the energy--by more immediate if cruder measures. They measured it by the damage it did as it threw ships or boats or bodies against rocks or sandbars. And they measured it by the work they had to perform to counter the river's work. They knew somethingwe have obscured and are only slowly recovering: labor rather than "conquering" nature involves human beings with the world so thoroughly that they can never be disentangled.gt;gt;During the forty-two days of Ross's first trip upriver from Astoria, the river demonstrated its power again and again. The river upset the Astorians' boat; it dunked the men, drenched them, grounded them, and delayed them. But mostly the river made them work, sweat, and hurt. "On the twenty-third [of the month] ... we started stemming a strong and almost irresistible current ..." The "current assumed double force, so that our paddles proved almost ineffectual; and to get on we were obliged to drag ourselves from point to point by laying hold of bushes and the branches of overhanging trees ..." "The burning sun of yesterday and the difficulty of stemming the rapid current had so reduced our strength that we made but little headway today." "We were again early at work, making the best of our way against a turbulent and still increasing current."gt;gt;Ross had reached the Cascades, the rapids where the Columbia bursts out of the mountains. Above the Cascades were even worse rapids at the Dalles, and the Dalles commenced with Celilo Falls. Here the current was too strong and travelers had to portage.gt;gt;Above Celilo Falls, Ross's litany of labor continued. "The current was strong and rapid the whole day." "[We] found the current so powerful that we had to lay our paddles aside and take to the lines." "The wind springing up, we hoisted sail, but found the experiment dangerous, owing to the rapidity of the current." And so they proceeded through Priest Rapids, where the "water rushes with great violence," and through lesser rapids where a whirlpool grabbed a boat, spun it several times, and sent it careening down a chain of cascades. Ross stopped at the Okanogan River. If he had gone farther, more rapids awaited: Kettle Falls, and farther still, the Dalles des Morts. The largest tributaries of the Columbia, the Snake and the Willamette, contributed falls and rapids of their own.gt;gt;So thoroughly did Ross come to measure the river by the labor he pitted against it, by the feel of his body, by the difficulties it presented, that his return downstream with the river's energy speeding him back to Astoria from Fort Okanogan could be contained in a sentence. "On the twenty-sixth of February, we began our homeward journey, and spent just twenty-five days on our way back."gt;gt;With so much energy deployed against them, it was remarkable that voyagers could proceed at all. The first white fur traders built what they called canoes out of cedar planks caulked with gum. Such boats could not stand the rapids. The Astorians longed for another Indian technology--the more familiar birchbark canoes of the eastern rivers. The Northwesters who succeeded the Astorians actually imported the birchbark necessary to make birchbark canoes.gt;gt;Efficient movement on the river demanded not just muscle power but knowledge and art. The fur traders, fortunately, had examples of both before them. In the Indians' cedar canoes, efficiency and art met and became one. The Indians carved each of their canoes from a single log; Gabriel Franchere, another of the original Astorians, reported that the largest canoes were thirty feet long and five feet wide. And as Robert Stuart, also an Astorian, wrote: "If perfect symmetry, smoothness and proportion constitute beauty, they surpass anything I ever beheld." Some were as "transparent as oiled paper."gt;gt;The art and knowledge embodied in the canoe demanded an equal knowledge of the river. Lewis and Clark were repeatedly amazed at the conditions Indians ventured out in, and William Clark had thought them "the best canoe navigators I ever Saw." Stuart concurred: The Indians were "the most expert paddle men any of us had ever seen." If the river overpowered their canoe, they would spring "into the water (more like amphibious animals than human beings), right and empty her, when with the greatest composure, they again get in and proceed." But the clearest mark of knowledge and skill was when nothing happened, when Indians knew which paths through the river were the most efficient and least demanding of human energy.gt;gt;The river's lessons that the Astorians learned, the North West Company men would have to relearn. The poverty of the boats and the inability to maneuver them that the governor-in-chief of the Hudson's Bay Company, George Simpson, found on his first voyage of inspection to the Columbia posts in 1824 provoked a spluttering astonishment that still resonates in his journal. "There is not," he wrote, "a Boat at the Establishment [Fort George] fit to cross the River in bad Weather nor a person competent to sail one." Simpson's attempt to cross in a boat with rotten rigging had proceeded only a mile before everyone on board was bailing with hats and buckets. The boat struck a sandbar and drifted off, with the crew rowing madly against an outgoing tide until they"exhausted their strength at the Oars." They were only saved when the tide turned and swept them back into the river, where they made shore, abandoned the boat, and walked back to the fort. Farther upriver, however, where Canadian boatmen were more in their element, the British naturalist David Douglas could in 1826 admire the "indescribable coolness" with which Canadians shot the rapids.gt;gt;The Canadians showed Douglas that the knowledge of how and where to use the boats was as important as the boats themselves; the complexities of the energy system of the river could be made to work for as well as against travelers. "Our Indians," the American explorer Charles Wilkes wrote in 1841, "cunningly kept close to the shore & thus took advantage of all the eddies." Such knowledge was initially a bodily knowledge felt and mastered through experience and labor. Even when learned from others, the messages sent through nerve and muscle constantly validated or modified acquired knowledge. Knowledge of the river was in large part knowing how its velocity varied and where it was turbulent. With proper experience, traveling against the current on the Columbia demanded less expenditure of human energy than traveling overland. The hydraulics of the river sketched out a map of energy; this geography of energy was also a geography of labor.gt;gt;George Simpson saw the world with the eyes of an adventurous accountant. He gauged rivers, as he judged his men and the Indians, by the work they did, the expense they required, and the profit the company might derive from them. In 1824, on first entering the Columbia near the Cedar River, he had found the current of the Columbia "so strong that at first sight one would scarcely suppose it possible to stem it even with the Towline." But "on more attentive observation it is found that in every reach there is a strong back current or eddy which renders it easy of ascent."gt;gt;The Columbia, as Simpson noted, does not travel at a constant speed along its bed. Friction divides its very current against itself. It divides it horizontally. Where the water meets earth and rock along the river's bed and banks, friction slows the current. Velocity increases away from the shore. The river's current also varies vertically. The river, in effect, is composed of layers. It is the fluid equivalent of a piece of plywood, but in the river's case each layer moves at a different velocity. The layer of greatest velocity is always below the surface. With a constant depth of flow, velocity increases toward the center of the river and rises towardthe surface. Where the channel is asymmetrical, maximum velocity shifts toward the deeper side.gt;gt;As Simpson noticed, the very velocity of the river created other compensatory effects that reduced human labor. Water, as a fluid, cannot resist stress. When the river's velocity reaches a certain point, the flow becomes turbulent. The layers mix; the flow at some points eddies back against the main current.gt;gt;The velocity of the river changes across both space and time. When the volume of water increases in spring and summer with melting snows from the mountains, friction does not increase proportionately. The area of bank and streambed increases by a much smaller increment than does the volume of water. When deep and full, rivers run faster than when shallow. Thus the velocity of the Columbia increases in the spring and summer, and it increases the farther one goes downstream.gt;gt;As every voyager on the river knew, it was not just speed that created turbulence; the flow of a river also depended on the roughness of its bed. Obstructions in its channel--rocks and boulders, trees or piers--separate its flow and create eddies. Eddies create the waves, vortices, and surges that characterize rapids. And the Columbia possessed some of the fiercest and largest rapids on the continent.gt;gt;The places on the Columbia marked by the greatest turbulence and velocity formed a gauntlet through which voyagers had to pass. Roughly eight hundred years ago a three-mile chunk of Table Mountain fell into the river, blocking it entirely. Stand at Bonneville Dam and you can see the gash it left in the mountain. One hundred and fifty miles from its mouth, the river eventually cut a rocky path through the slide's outer edge, forming the Cascades. Robert Stuart described the current as that "of a Mill Sluice, and so rough that the Ocean agitated by a tempest would be but a faint comparison."gt;gt;Roughly forty miles above the Cascades came the Dalles or Long Narrows, where a basalt flow constricted the Columbia. Narrowing the channel increased the velociy of the Columbia in the same way that partially blocking the outlet of a hose with your thumb increases the water's velocity. In the words of David Thompson, a North West Company man who probably knew the continent more intimately than any other human alive, the "walls of Rock contract the River from eight hundred to one thousand yards in width to sixty yards or less: imagination can hardly form an idea of the working of this immense body of waterunder such compression, raging and hissing as if alive." To William Clark it was an "agitated gut Swelling, boiling and Whorling in every direction." At full flood the river rose high up the narrow gorge. David Douglas saw tree trunks "3 feet in diameter ... on the rocks, 43 feet above the present level ... placed there by the water." Just as compression increased speed and energy, so did gravity when the incline of the river's bed steepened. Immediately above the Dalles, at Celilo Falls, cascading water increased in velocity and thus increased the amount of kinetic energy it produced.gt;gt;At these places where the river narrowed and/or fell in a short distance, the river's energy was greatest. The river became dramatic and dangerous. Falls and rapids yielded disproportionate death to those inexperienced at handling boats or cedar canoes or those who chose risk over the labor of portage. There was, however, danger no matter how great the skill of the paddlers.gt;gt;The early accounts of missionaries provide a grim narrative of the dangers of rivers. "The water being very high and the current strong," was the Methodist Elijah White's prologue to an 1843 accident in which a canoe carrying four whites and four Indians was swept over Willamette Falls on the Willamette River. A hopeless effort to battle the current, a "thrilling shriek" from Mrs. Rogers, and the victims were gone. Two Indians jumped and survived. Everyone else died. Five years earlier an Indian canoe carrying missionaries attempted to run the Cascades and overturned. When it was righted and brought to shore, the Indian crew found the dead body of the drowned infant son of Mrs. Elijah White in the canoe. A short time earlier a Hudson's Bay canoe with seven men was lost at the same place.gt;gt;It took only bad luck, a moment's panic, or a lapse of skill for the river to claim its toll. The Dalles des Morts of the Columbia received its name in the 1820s when the river had wrecked a Hudson's Bay Company party, killing five men and reducing one survivor to cannibalism. Near the Dalles proper, nine men drowned in 1830 on a stretch of the river not considered especially dangerous. And in 1842 Father Pierre De Smet, who described the Columbia as "but a succession of dangers," watched in horror as what appears to have been the Whirlpool Rapids near Kalichen Falls swallowed a Hudson's Bay Company bateau, drowning five bargemen.gt;gt;These rapids and falls created the most revealing places on the river.They were critical sites in a geography of energy, and they were critical places in the social, cultural, and political geography humans constructed. A scholar needs to consider them at least as carefully and from as many angles as a boatman preparing to run them.gt;gt;As we now understand rivers, they seek the most efficient and uniform expenditure of energy possible. Rivers constantly adjust; they compensate for events that affect them. They are, in this sense, historical: products of their own past history. "The river channel," concluded one geomorphologist, is "a form representing the most efficient--in terms of energy utilization--geometry capable of accommodating the sum total of the means and extremes of variability of flow that have occurred in that channel throughout its history."gt;gt;Where obstacles slow rivers, rivers try to restore an even velocity; where the gradient increases or the channel constricts, rivers try to widen or build up their bed. The Columbia ceaselessly worked to widen the Dalles and it responded to Celilo Falls by working to downcut the falls and erode the plunge pools until the falls themselves eventually would even out and disappear. When an obstacle such as a beaver dam or a hydraulic dam slows a river's current, for example, its speed and energy decrease. The river drops part of its load--the material it works to move. It gradually builds up its own bed and increases its gradient, thus increasing its speed and its kinetic energy. Eventually it will remove the obstacle.gt;gt;In the long run the river's work of eliminating obstructions aids the human work of moving up and down rivers. But in the short run rapids and falls demand greater expenditures of human energy to counter the river's energy. This combination of energies bonded the material and social; the natural and cultural intertwined. The geography of energy intersected quite tightly with a geography of danger and a human geography of labor. Precisely where the river expended its greatest energy, humans had to expend the most labor and confront the greatest danger.gt;gt;At the falls and rapids travelers had to portage. Indians living at the Cascades had canoes at either end of the portages, but travelers had to carry their cargo and either tow or carry their boats. It was hard and demanding work. Portaging the Cascades brought Lewis and Clark much "difficulty and labour," cost them a pirogue, and left their men "so much fatigued" that they granted them a respite. The missionaryMrs. Elijah White, whose baby drowned at the Cascades, had gladly reembarked two-thirds through the portage because she and David Leslie "with wet feet and fatigue were very uncomfortable." Going upstream, everyone had to portage; going downstream, danger could be substituted for labor.gt;gt;The Cascades and the Dalles were the most dangerous points on the river and the longest portages. At the Cascades--which one of the literary Astorians described as "that rocky and dangerous portage"--the "laborious task of carrying" made clear the distinction between the work of the river and the work of human beings. In one sense, the expenditure of energy by human workers was as natural as the energy of the river, but human work was socially organized and given cultural meaning. The Cascades and the Dalles, for example, bared class divisions among the Astorians and revealed their relation to work and power. Ross, "not being accustomed myself to carry," instead stood armed as a sentinel against the Indians, but with those subordinate to him "wearied to death," he took up a load. The first ascent left him breathless and able to "proceed no farther." He hired an Indian to carry the load, and the Indian proceeded "full trot" across the portage, only to pitch the pack of tobacco over a two-hundred-foot precipice at the end. He and fifty others laughed uproariously as Ross scrambled to retrieve the load. The joke was about work and power, weakness and dominance, all of which were physical and social.gt;gt;The river demanded energy to match its energy, and this shaped and revealed the organization of work. The necessity of portages and the limits of human labor caused the Hudson's Bay Company to transport all its goods in ninety-pound packages. The expenditure of labor in carrying these packages involved numerous acts of calculation, conflict, abuse, and cooperation. In these acts a social order became transparent.gt;gt;If all journeys were downstream, if there had been no rapids or falls, then the human relations on the early-nineteenth-century river would have been different. The labor white men expended in the ascent forced them into close contact with Indians. The knowledge that in passing upstream they had to travel close to shore to take advantage of back-currents encouraged efforts to accommodate Indians. David Thompson, the remarkable North West Company explorer who descended the Columbia just as the Astorians were arriving at its mouth, succinctlycalculated the social result of this mix of river energy and human labor when he explained why he stopped to smoke and exchange gifts with the Sanpoils as he passed downstream.gt;gt;gt;My reason for putting ashore and smoking with the Natives, is to make friends with them, against my return, for in descending the current of a large River, we might pass on without much attention to them; but in returning against the current, our progress will be slow and close along the shore, and consequently very much in their power; whereas staying a few hours, and smoking with them, while explaining to them the object of my voyage makes them friendly to us.gt;gt;gt;Passage along the river was, Thompson realized, not just physical; it was social and political. Social and political rituals were as necessary as labor to move against the current. Indians expected gifts and ritual at the portages. The failure of whites to meet such expectations brought conflict from the time of the Lewis and Clark expedition until the 1820s.gt;gt;In English the words "energy" and "power" have become virtually interchangeable. Horsepower is, for example, a technical measure of energy. But we also speak metaphorically of the power of the state. Thompson spoke of being "in the power" of the Indians. The conflation is partially metaphorical, but it also arises because both meanings involve the ability to do work, to command labor. To be powerful is to be able to accomplish things, to be able to turn the energy and work of nature and humans to your own purposes.gt;gt;We conflate energy and power, the natural and the cultural, in language, but they are equally mixed as social fact at the rapids and portages. The energy system of the Columbia determined where humans would portage, but human labor created the actual route of the portage, and human social relations determined its final social form and outcome. The Dalles, per se, did not cause Ross's dilemma. Ross's humiliation was an incident of power. Human labor would later make the Dalles and the Cascades the sites of dams that produced energy--power; they were, however, long before this, sites at which humans contested over social power--the ability to gain advantage from the labor of others.gt;gt;Spatial arrangements matter a great deal in human history. They reveal the social arrangements that help produce them. The repeated conflicts at the Dalles and the Cascades revolved around a particular organization of space. Whites regarded the space at the Cascades and the Dalles as open, as culturally empty. Indians regarded it as full. In a space that brought together many different peoples, Indians expected gifts to mediate and smooth passages through this social maze. Too often whites replaced gifts with force; they resented what they perceived as theft and pillage. The space became uniquely violent.gt;gt;gt;gt;gt;IIgt;gt;gt;gt;Egt;xamining how hu

lgli/The Organic Machine_ The Remaking of the C - Richard White.epub
The Organic Machine: The Remaking of the Columbia River (Hill and Wang Critical Issues) Richard White; consulting editor, Eric Foner Hill & Wang: Farrar, Straus and Giroux, 1995
Literary awards: Washington State Book Award (1996) The Hill and Wang Critical Issues Series: concise, affordable works on pivotal topics in American history, society, and politics. In this pioneering study, White explores the relationship between the natural history of the Columbia River and the human history of the Pacific Northwest for both whites and Native Americans. He concentrates on what brings humans and the river together: not only the physical space of the region but also, and primarily, energy and work. For working with the river has been central to Pacific Northwesterners' competing ways of life. It is in this way that White comes to view the Columbia River as an organic machine--with conflicting human and natural claims--and to show that whatever separation exists between humans and nature exists to be crossed. _________________________ In The Organic Machine, Richard White, a distinguished historian and leading scholar of the American West, explores the intimate relationship between nature and mankind along the Columbia River. Working on the cutting edge of environmental and social history, White demonstrates how, over the centuries, both native peoples and settlers have continually remade the river, treating it as a machine designed to churn out energy and sustenance. He assesses the impact on the Northwest ecology of enterprises that have marked the river's history, from salmon fishing to the Hanford Energy Works nuclear plant, and eloquently reveals the insights and illusions of those who work with the river. Review “Visionary . . . White has posed a brilliant new model for environmental history.” ―Howard R. Lamar, Yale University “A crystalline gem of a book. White makes the transformation of the Columbia River basin into a compelling microhistory of the encounter between the forces of technology and nature in America.” ―Leo Marx, Massachusetts Institute of Technology “White has done something remarkable: he has shown us a way of thinking that connects our deep history to the present and sees our most essential human habits--work, in this case--as inseparable from the places we inhabit.” ―Elliott West, University of Arkansas From the Back Cover In The Organic Machine, Richard White, a distinguished historian and leading scholar of the American West, explores the intimate relationship between nature and mankind along the Columbia River. Working on the cutting edge of environmental and social history, White demonstrates how, over the centuries, both native peoples and settlers have continually remade the river, treating it as a machine designed to churn out energy and sustenance.

Our Politics, Our Selves? : Liberalism, Identity, and Harm Peter Digeser Princeton University Press, First Edition / First Printing, 1995
Is statecraft soulcraft? Should we look to our souls and selves in assessing the quality of our politics? Is it the business of politics to cultivate, shape, or structure our internal lives? Summarizing and answering the major theoretical positions on these issues, Peter Digeser formulates a qualified permission to protect or encourage particular forms of human identity. Public discourse on politics should not preclude talk about the role of reason in our souls or the importance of wholeness and community to our selves or the significance of autonomy for individuals. However, those who seek to place only their own conception of the self or soul within the reach of politics are as mistaken as those who would completely preclude such matters from the political realm. In proposing this view, Digeser responds to communitarians, classical political rationalists, and genealogists who argue that liberal culture fragments, debases, or normalizes our selves. He also critically analyzes perfectionist liberals who justify liberalism by virtue of its ability to cultivate autonomy and authenticity, as well as liberal neutralists who wish to avoid altogether the problem of selfcraft. All these, he argues, fall short in some way in defining the extent to which politics should be concerned with the self.

Digital Logic Circuit Analysis and Design Victor P. Nelson, H. Troy Nagle, J. David Irwin, Bill D. Carroll Prentice Hall, 1st, 1995
For introductory digital logic design or computer engineering courses in electrical and computer engineering or computer science at the sophomore- or junior-level. Many recent texts place instructors in the difficult position of chosing between authoritative, state-of-the art coverage and an approach that is highly supportive of student learning. This carefully developed text was widely praised by reviewers for both its great clarity and its rigor. The book balances theory and practice in depth without getting bogged down in excessive technical or mathematical language and has abundant coverage of current topics of interest, such as programmable devices, computer-aided design, and testability. An unusually large number of illustrations, examples, and problems help students gain a solid sense of how theory underlies practice.

Curve and Surface Fitting with Splines (Monographs on Numerical Analysis) Paul Dierckx Oxford University Press, USA, Monographs on numerical analysis, Oxford, New York, England, 1993
The fitting of a curve or surface through a set of observational data is a recurring problem across numerous disciplines such as applications. This book describes the algorithms and mathematical fundamentals of a widely used software package for data fitting with tensor product splines. It gives a survey of possibilities, benefits, and problems commonly confronted when approximating with this popular type of function. Dierkx demonstrates in detail how the properties of B -splines can be fully exploited for improving the computational efficiency and for incorporating different boundary or shape preserving constraints. Special attention is also paid to strategies for an automatic and adaptive knot selection with intent to obtain serious data reductions. The practical use of the smoothing software is illustrated with many theoretical and practical examples.

A Dictionary of Philosophical Quotations (Blackwell Reference) edited by A.J. Ayer and Jane O'Grady Oxford, UK ; Cambridge, MA, USA: Blackwell Publishers, Blackwell reference, Oxford, UK, Cambridge, MA, USA, England, 1994
<p><P>The dictionary shows philosophers at their best (and their worst), at their most perverse and their most elegant. Organised by philosopher, and indexed by thought, concept and phrase, it enables readers to discover who said what, and what was said by whom. Over 300 philosophers are represented, from Aristotle to Zeno, including Einstein, Aquinas, Sartre and De Beauvoir, and the quotations range from short cryptic phrases to longer statements. <br>This <i> Dictionary of Philosophical Quotations </i> will not change your life. It will change your mind.</p> <h3>Library Journal</h3> <p>Here is Sir Karl Popper's reminder that ``the history of science is a history of irresponsible ideas . . . and of error''--which he says is a good thing. Here, too, is Pascal's insight that ``man is only a reed . . . but he is a thinking reed'' and Aristotle's advice that ``piety requires us to honor truth above our friends.'' But this is an uneven book. While the late Sir Alfred Ayer's coeditor included three pages of his portentous sayings (and none of his witty ones), John Henry Newman and the Cambridge Platonists are nowhere to be found, the British Idealists are reduced to a mere trace, and Nicolas Malebranche gets only a paragraph. About a third of the book is taken up with recent analytic philosophers, many of whom will be forgotten before the book is out of print. The quotations are organized alphabetically by author, and the general reader--to whom many recent figures will be strange--must work hard to use it. Of course, readers may be better off with the names they do recognize, and Plato, Kant, Aquinas, Aristotle, Descartes, Locke, and Hume are well represented.-- Leslie Armour, Univ. of Ottawa , Ontario</p>

The Organic Machine: The Remaking of the Columbia River (Hill and Wang Critical Issues) Richard White, White, Richard Hill and Wang, Hill and Wang Critical Issues Series, 1995
gt;gt;The Organic Machinegt;gt;gt;gt;gt;gt;CHAPTER 1gt;gt;gt;gt;Knowing Nature through Labor: Energy, Salmon Society on the Columbiagt;gt;gt;gt;gt;Igt;gt;gt;gt;Tgt;he world is in motion. Tectonic plates drift across a spinning planet. Mountains are lifted up and eroded to the sea. Glaciers advance and retreat. All natural features move, but few natural features move so obviously as rivers. Our metaphors for rivers are all metaphors of movement: they run and roll and flow.gt;gt;Like us, rivers work. They absorb and emit energy; they rearrange the world. The Columbia has been working for millennia. During the Miocene, volcanic eruptions deposited layers of basalt across the Columbia Plain. The upper Columbia cut a gutter through which it ran along the margins of the basaltic flow. At Wenatchee the rise of the Horse Heaven anticline caused the river to cut into the basalt; it drained into the Pasco basin, the lowest point on its route east of the Cascades, and emerged from the basin at the Wallula Gap. During the Pleistocene the collapse of an ice dam holding glacial Lake Missoula created the largest known freshwater flood in the earth's history. It was an afternoon's work for one of the Missoula floods to create the Grand Coulee and other rock channels of the Channeled Scablands. In those few hours it accomplished work that it would have taken the Mississippi three hundred years at full flood to duplicate. The flood rushed into the Columbia channel and finally slowed enough to create the "Portland Delta" of the Willamette lowlands. Since then ice dams have blocked the Columbia's bed, temporarily spilling the river into the Grand Coulee;mountains have slid into it, and humans have dammed it. All these changes have left work for the river to do.gt;gt;For much of human history, work and energy have linked humans and rivers, humans and nature. But today, except when disaster strikes, when a hurricane hits, or earthquakes topple our creations, or when a river unexpectedly rises and sweeps away the results of our effort and labor, we forget the awesome power--the energy--of nature. There is little in our day-to-day life to preserve the connection. Machines do most of our work; we disparage physical labor and laborers. The link between our work and nature's work has weakened. We no longer understand the world through labor. Once the energy of the Columbia River was felt in human bones and sinews; human beings knew the river through the work the river demanded of them.gt;gt;Early-nineteenth-century accounts of the Columbia can be read in many ways, but they are certainly all accounts of work, sweat, exhaustion, and fear. The men of the early nineteenth century who wrote the Lewis and Clark journals and the accounts of the Astorian trading post, the North West Company and Hudson's Bay Company, knew the energy of the river. They had to expend their own energy to move up, down, and across it. Alexander Ross's marvelous gt;Adventures of the First Settlers on the Oregon or Columbia Rivergt;, a narrative of the arrival of the Astorians and the establishment of the fur-trading outpost of Astoria in 1811, can serve as a primer on the Columbia as an energy system during a time when human beings--Indian and white--had only the wind and the strength of their own muscles to match against the powerful currents of the river.gt;gt;"The mouth of the Columbia River," Ross wrote, "is remarkable for its sand bars and high surf at all seasons, but more particularly in the spring and fall, during the equinoctial gales." The shoals and sandbars at the Columbia's mouth are relicts of its work and energy. In areas without strong tidal action a river deposits the load it carries to its mouth as a delta, but the Columbia emerges into the Pacific in an area of strong tides and persistent storms.gt;gt;The river's current and the tides battle at the Columbia's mouth and prevent the formation of a delta. At full flood, Captain Charles Wilkes wrote in 1841, one could "scarcely have an idea of its flow how swollen it is, and to see the huge trunks of thick gigantic forests borne like chips on its bosom astonishes one." During ebb tides the river pushes itsfreshwater out many miles into the sea. The tides, in turn, are felt as high as 140 miles upriver when the Columbia's water level is at its fall and winter low. This pushing and pulling produces a set of sandbars and islands at the river's mouth. Ocean currents and tides force themselves against the bars with "huge waves and foaming breakers." The result is "a white foaming sheet for many miles, both south and north of the mouth of the river, forming as it were an impracticable barrier to the entrance, and threatening with instant destruction everything that comes near it." To enter the river, ships, powered only by wind and aided by the tide, or boats and canoes powered by human muscle, had to pass through this barrier.gt;gt;During the Astorians' own terrible entry into the Columbia in 1811, they sent out small boats to find a channel into the river for their ship, the Tonquin. In Ross's dramatic telling, the Astorians watched as the Tonquin's first officer, Ebenezer Fox, protested to Captain Jonathan Thorn that the seas were "too high for any boat to live in." In reply Thorn only taunted Fox: "Mr. Fox, if you are afraid of water, you should have remained at Boston." Fox's uncle had died at the mouth of the Columbia. In despair Fox announced that he was "going to lay my bones with his." He shook hands with the Astorians and, getting into the boat, shouted, "Farewell, my friends ... we will perhaps meet again in the next world." Fox's crew was inexperienced and the sea violent. Not one hundred yards from the ship the boat became unmanageable. The waves hit the craft broadside, whirled it like a top, and "tossing on the crest of a huge wave, [it would] sink again for a time and disappear all together." Fox hoisted a flag to signal his distress, but the gt;Tonquingt; turned about, and they "saw the ill-fated boat no more."gt;gt;Ross himself took part in a second attempt, and he discovered more immediately the experience of pitting human energy against the energy focused at the mouth of the river. As they first approached the bar with its "terrific chain of breakers," the "fearful suction or current" gripped the boat before they realized what had happened. The second officer, Mr. Mumford, called for them to match their strength against that of the river and sea: "Let us turn back, and pull for your lives. Pull hard, or you are all dead men." They pulled hard and survived, but this attempt to enter the river and two more failed. The gt;Tonquingt; eventually made the passage across the bar, but only after eight men had died.gt;gt;In their ordeal at the bar the Astorians had confronted storms, sandbars,and currents; men had labored and died. But wave, water, and wind--and human labor--can be represented in ways beyond the immediacy of actual experience. We can abstract them to a single entity: energy. There is a physics to the gt;Tonquin'sgt; drama at the river's mouth, and it leads outward beyond the earth to the sun and the moon. Lunar gravitation causes the tides, but virtually all the rest of the energy manifest at the Columbia's mouth originates in the sun. The sun, in effect, provides fuel for a giant atmospheric heat engine which evaporates water from the oceans and produces winds that move the moisture over land. As the clouds cool, the moisture falls as rain. Without solar energy to move the water inland and uphill, rivers would never begin; without gravity to propel the water downhill back toward the ocean, rivers would never flow. In a real sense the Columbia begins everywhere that the rain that eventually enters it falls. The Columbia gathers its water from an area of 258,200 square miles, but not all that water finds its way into the river as it flows 1,214 miles to the sea. Some of it is lost through transpiration and use in plant tissues; some is lost through evaporation.gt;gt;Physicists define energy as the capacity to do work. Work, in turn, is the product of a force acting on a body and the distance the body is moved in the direction of the force. Push a large rock and you are expending energy and doing work; the amount of each depends on how large the rock and how far you push it. The weight and flow of water produce the energy that allows rivers to do the work of moving rock and soil: the greater the volume of water in the river and the steeper the gradient of its bed, the greater its potential energy.gt;gt;In fact, however, neither the Columbia nor any other river realizes all of its potential energy as work. Indeed, only about 2 percent of the river's potential energy results in work: the erosion, transportation, and deposition of matter. About 98 percent of the river's kinetic energy is expended in friction as the moving water rubs against itself, its bed, and its bank. This energy is dissipated as heat within the river.gt;gt;Engineers can measure the potential energy and the kinetic energy of the Columbia with some precision, but early voyagers like Ross recognized the power--the energy--by more immediate if cruder measures. They measured it by the damage it did as it threw ships or boats or bodies against rocks or sandbars. And they measured it by the work they had to perform to counter the river's work. They knew somethingwe have obscured and are only slowly recovering: labor rather than "conquering" nature involves human beings with the world so thoroughly that they can never be disentangled.gt;gt;During the forty-two days of Ross's first trip upriver from Astoria, the river demonstrated its power again and again. The river upset the Astorians' boat; it dunked the men, drenched them, grounded them, and delayed them. But mostly the river made them work, sweat, and hurt. "On the twenty-third [of the month] ... we started stemming a strong and almost irresistible current ..." The "current assumed double force, so that our paddles proved almost ineffectual; and to get on we were obliged to drag ourselves from point to point by laying hold of bushes and the branches of overhanging trees ..." "The burning sun of yesterday and the difficulty of stemming the rapid current had so reduced our strength that we made but little headway today." "We were again early at work, making the best of our way against a turbulent and still increasing current."gt;gt;Ross had reached the Cascades, the rapids where the Columbia bursts out of the mountains. Above the Cascades were even worse rapids at the Dalles, and the Dalles commenced with Celilo Falls. Here the current was too strong and travelers had to portage.gt;gt;Above Celilo Falls, Ross's litany of labor continued. "The current was strong and rapid the whole day." "[We] found the current so powerful that we had to lay our paddles aside and take to the lines." "The wind springing up, we hoisted sail, but found the experiment dangerous, owing to the rapidity of the current." And so they proceeded through Priest Rapids, where the "water rushes with great violence," and through lesser rapids where a whirlpool grabbed a boat, spun it several times, and sent it careening down a chain of cascades. Ross stopped at the Okanogan River. If he had gone farther, more rapids awaited: Kettle Falls, and farther still, the Dalles des Morts. The largest tributaries of the Columbia, the Snake and the Willamette, contributed falls and rapids of their own.gt;gt;So thoroughly did Ross come to measure the river by the labor he pitted against it, by the feel of his body, by the difficulties it presented, that his return downstream with the river's energy speeding him back to Astoria from Fort Okanogan could be contained in a sentence. "On the twenty-sixth of February, we began our homeward journey, and spent just twenty-five days on our way back."gt;gt;With so much energy deployed against them, it was remarkable that voyagers could proceed at all. The first white fur traders built what they called canoes out of cedar planks caulked with gum. Such boats could not stand the rapids. The Astorians longed for another Indian technology--the more familiar birchbark canoes of the eastern rivers. The Northwesters who succeeded the Astorians actually imported the birchbark necessary to make birchbark canoes.gt;gt;Efficient movement on the river demanded not just muscle power but knowledge and art. The fur traders, fortunately, had examples of both before them. In the Indians' cedar canoes, efficiency and art met and became one. The Indians carved each of their canoes from a single log; Gabriel Franchere, another of the original Astorians, reported that the largest canoes were thirty feet long and five feet wide. And as Robert Stuart, also an Astorian, wrote: "If perfect symmetry, smoothness and proportion constitute beauty, they surpass anything I ever beheld." Some were as "transparent as oiled paper."gt;gt;The art and knowledge embodied in the canoe demanded an equal knowledge of the river. Lewis and Clark were repeatedly amazed at the conditions Indians ventured out in, and William Clark had thought them "the best canoe navigators I ever Saw." Stuart concurred: The Indians were "the most expert paddle men any of us had ever seen." If the river overpowered their canoe, they would spring "into the water (more like amphibious animals than human beings), right and empty her, when with the greatest composure, they again get in and proceed." But the clearest mark of knowledge and skill was when nothing happened, when Indians knew which paths through the river were the most efficient and least demanding of human energy.gt;gt;The river's lessons that the Astorians learned, the North West Company men would have to relearn. The poverty of the boats and the inability to maneuver them that the governor-in-chief of the Hudson's Bay Company, George Simpson, found on his first voyage of inspection to the Columbia posts in 1824 provoked a spluttering astonishment that still resonates in his journal. "There is not," he wrote, "a Boat at the Establishment [Fort George] fit to cross the River in bad Weather nor a person competent to sail one." Simpson's attempt to cross in a boat with rotten rigging had proceeded only a mile before everyone on board was bailing with hats and buckets. The boat struck a sandbar and drifted off, with the crew rowing madly against an outgoing tide until they"exhausted their strength at the Oars." They were only saved when the tide turned and swept them back into the river, where they made shore, abandoned the boat, and walked back to the fort. Farther upriver, however, where Canadian boatmen were more in their element, the British naturalist David Douglas could in 1826 admire the "indescribable coolness" with which Canadians shot the rapids.gt;gt;The Canadians showed Douglas that the knowledge of how and where to use the boats was as important as the boats themselves; the complexities of the energy system of the river could be made to work for as well as against travelers. "Our Indians," the American explorer Charles Wilkes wrote in 1841, "cunningly kept close to the shore & thus took advantage of all the eddies." Such knowledge was initially a bodily knowledge felt and mastered through experience and labor. Even when learned from others, the messages sent through nerve and muscle constantly validated or modified acquired knowledge. Knowledge of the river was in large part knowing how its velocity varied and where it was turbulent. With proper experience, traveling against the current on the Columbia demanded less expenditure of human energy than traveling overland. The hydraulics of the river sketched out a map of energy; this geography of energy was also a geography of labor.gt;gt;George Simpson saw the world with the eyes of an adventurous accountant. He gauged rivers, as he judged his men and the Indians, by the work they did, the expense they required, and the profit the company might derive from them. In 1824, on first entering the Columbia near the Cedar River, he had found the current of the Columbia "so strong that at first sight one would scarcely suppose it possible to stem it even with the Towline." But "on more attentive observation it is found that in every reach there is a strong back current or eddy which renders it easy of ascent."gt;gt;The Columbia, as Simpson noted, does not travel at a constant speed along its bed. Friction divides its very current against itself. It divides it horizontally. Where the water meets earth and rock along the river's bed and banks, friction slows the current. Velocity increases away from the shore. The river's current also varies vertically. The river, in effect, is composed of layers. It is the fluid equivalent of a piece of plywood, but in the river's case each layer moves at a different velocity. The layer of greatest velocity is always below the surface. With a constant depth of flow, velocity increases toward the center of the river and rises towardthe surface. Where the channel is asymmetrical, maximum velocity shifts toward the deeper side.gt;gt;As Simpson noticed, the very velocity of the river created other compensatory effects that reduced human labor. Water, as a fluid, cannot resist stress. When the river's velocity reaches a certain point, the flow becomes turbulent. The layers mix; the flow at some points eddies back against the main current.gt;gt;The velocity of the river changes across both space and time. When the volume of water increases in spring and summer with melting snows from the mountains, friction does not increase proportionately. The area of bank and streambed increases by a much smaller increment than does the volume of water. When deep and full, rivers run faster than when shallow. Thus the velocity of the Columbia increases in the spring and summer, and it increases the farther one goes downstream.gt;gt;As every voyager on the river knew, it was not just speed that created turbulence; the flow of a river also depended on the roughness of its bed. Obstructions in its channel--rocks and boulders, trees or piers--separate its flow and create eddies. Eddies create the waves, vortices, and surges that characterize rapids. And the Columbia possessed some of the fiercest and largest rapids on the continent.gt;gt;The places on the Columbia marked by the greatest turbulence and velocity formed a gauntlet through which voyagers had to pass. Roughly eight hundred years ago a three-mile chunk of Table Mountain fell into the river, blocking it entirely. Stand at Bonneville Dam and you can see the gash it left in the mountain. One hundred and fifty miles from its mouth, the river eventually cut a rocky path through the slide's outer edge, forming the Cascades. Robert Stuart described the current as that "of a Mill Sluice, and so rough that the Ocean agitated by a tempest would be but a faint comparison."gt;gt;Roughly forty miles above the Cascades came the Dalles or Long Narrows, where a basalt flow constricted the Columbia. Narrowing the channel increased the velociy of the Columbia in the same way that partially blocking the outlet of a hose with your thumb increases the water's velocity. In the words of David Thompson, a North West Company man who probably knew the continent more intimately than any other human alive, the "walls of Rock contract the River from eight hundred to one thousand yards in width to sixty yards or less: imagination can hardly form an idea of the working of this immense body of waterunder such compression, raging and hissing as if alive." To William Clark it was an "agitated gut Swelling, boiling and Whorling in every direction." At full flood the river rose high up the narrow gorge. David Douglas saw tree trunks "3 feet in diameter ... on the rocks, 43 feet above the present level ... placed there by the water." Just as compression increased speed and energy, so did gravity when the incline of the river's bed steepened. Immediately above the Dalles, at Celilo Falls, cascading water increased in velocity and thus increased the amount of kinetic energy it produced.gt;gt;At these places where the river narrowed and/or fell in a short distance, the river's energy was greatest. The river became dramatic and dangerous. Falls and rapids yielded disproportionate death to those inexperienced at handling boats or cedar canoes or those who chose risk over the labor of portage. There was, however, danger no matter how great the skill of the paddlers.gt;gt;The early accounts of missionaries provide a grim narrative of the dangers of rivers. "The water being very high and the current strong," was the Methodist Elijah White's prologue to an 1843 accident in which a canoe carrying four whites and four Indians was swept over Willamette Falls on the Willamette River. A hopeless effort to battle the current, a "thrilling shriek" from Mrs. Rogers, and the victims were gone. Two Indians jumped and survived. Everyone else died. Five years earlier an Indian canoe carrying missionaries attempted to run the Cascades and overturned. When it was righted and brought to shore, the Indian crew found the dead body of the drowned infant son of Mrs. Elijah White in the canoe. A short time earlier a Hudson's Bay canoe with seven men was lost at the same place.gt;gt;It took only bad luck, a moment's panic, or a lapse of skill for the river to claim its toll. The Dalles des Morts of the Columbia received its name in the 1820s when the river had wrecked a Hudson's Bay Company party, killing five men and reducing one survivor to cannibalism. Near the Dalles proper, nine men drowned in 1830 on a stretch of the river not considered especially dangerous. And in 1842 Father Pierre De Smet, who described the Columbia as "but a succession of dangers," watched in horror as what appears to have been the Whirlpool Rapids near Kalichen Falls swallowed a Hudson's Bay Company bateau, drowning five bargemen.gt;gt;These rapids and falls created the most revealing places on the river.They were critical sites in a geography of energy, and they were critical places in the social, cultural, and political geography humans constructed. A scholar needs to consider them at least as carefully and from as many angles as a boatman preparing to run them.gt;gt;As we now understand rivers, they seek the most efficient and uniform expenditure of energy possible. Rivers constantly adjust; they compensate for events that affect them. They are, in this sense, historical: products of their own past history. "The river channel," concluded one geomorphologist, is "a form representing the most efficient--in terms of energy utilization--geometry capable of accommodating the sum total of the means and extremes of variability of flow that have occurred in that channel throughout its history."gt;gt;Where obstacles slow rivers, rivers try to restore an even velocity; where the gradient increases or the channel constricts, rivers try to widen or build up their bed. The Columbia ceaselessly worked to widen the Dalles and it responded to Celilo Falls by working to downcut the falls and erode the plunge pools until the falls themselves eventually would even out and disappear. When an obstacle such as a beaver dam or a hydraulic dam slows a river's current, for example, its speed and energy decrease. The river drops part of its load--the material it works to move. It gradually builds up its own bed and increases its gradient, thus increasing its speed and its kinetic energy. Eventually it will remove the obstacle.gt;gt;In the long run the river's work of eliminating obstructions aids the human work of moving up and down rivers. But in the short run rapids and falls demand greater expenditures of human energy to counter the river's energy. This combination of energies bonded the material and social; the natural and cultural intertwined. The geography of energy intersected quite tightly with a geography of danger and a human geography of labor. Precisely where the river expended its greatest energy, humans had to expend the most labor and confront the greatest danger.gt;gt;At the falls and rapids travelers had to portage. Indians living at the Cascades had canoes at either end of the portages, but travelers had to carry their cargo and either tow or carry their boats. It was hard and demanding work. Portaging the Cascades brought Lewis and Clark much "difficulty and labour," cost them a pirogue, and left their men "so much fatigued" that they granted them a respite. The missionaryMrs. Elijah White, whose baby drowned at the Cascades, had gladly reembarked two-thirds through the portage because she and David Leslie "with wet feet and fatigue were very uncomfortable." Going upstream, everyone had to portage; going downstream, danger could be substituted for labor.gt;gt;The Cascades and the Dalles were the most dangerous points on the river and the longest portages. At the Cascades--which one of the literary Astorians described as "that rocky and dangerous portage"--the "laborious task of carrying" made clear the distinction between the work of the river and the work of human beings. In one sense, the expenditure of energy by human workers was as natural as the energy of the river, but human work was socially organized and given cultural meaning. The Cascades and the Dalles, for example, bared class divisions among the Astorians and revealed their relation to work and power. Ross, "not being accustomed myself to carry," instead stood armed as a sentinel against the Indians, but with those subordinate to him "wearied to death," he took up a load. The first ascent left him breathless and able to "proceed no farther." He hired an Indian to carry the load, and the Indian proceeded "full trot" across the portage, only to pitch the pack of tobacco over a two-hundred-foot precipice at the end. He and fifty others laughed uproariously as Ross scrambled to retrieve the load. The joke was about work and power, weakness and dominance, all of which were physical and social.gt;gt;The river demanded energy to match its energy, and this shaped and revealed the organization of work. The necessity of portages and the limits of human labor caused the Hudson's Bay Company to transport all its goods in ninety-pound packages. The expenditure of labor in carrying these packages involved numerous acts of calculation, conflict, abuse, and cooperation. In these acts a social order became transparent.gt;gt;If all journeys were downstream, if there had been no rapids or falls, then the human relations on the early-nineteenth-century river would have been different. The labor white men expended in the ascent forced them into close contact with Indians. The knowledge that in passing upstream they had to travel close to shore to take advantage of back-currents encouraged efforts to accommodate Indians. David Thompson, the remarkable North West Company explorer who descended the Columbia just as the Astorians were arriving at its mouth, succinctlycalculated the social result of this mix of river energy and human labor when he explained why he stopped to smoke and exchange gifts with the Sanpoils as he passed downstream.gt;gt;gt;My reason for putting ashore and smoking with the Natives, is to make friends with them, against my return, for in descending the current of a large River, we might pass on without much attention to them; but in returning against the current, our progress will be slow and close along the shore, and consequently very much in their power; whereas staying a few hours, and smoking with them, while explaining to them the object of my voyage makes them friendly to us.gt;gt;gt;Passage along the river was, Thompson realized, not just physical; it was social and political. Social and political rituals were as necessary as labor to move against the current. Indians expected gifts and ritual at the portages. The failure of whites to meet such expectations brought conflict from the time of the Lewis and Clark expedition until the 1820s.gt;gt;In English the words "energy" and "power" have become virtually interchangeable. Horsepower is, for example, a technical measure of energy. But we also speak metaphorically of the power of the state. Thompson spoke of being "in the power" of the Indians. The conflation is partially metaphorical, but it also arises because both meanings involve the ability to do work, to command labor. To be powerful is to be able to accomplish things, to be able to turn the energy and work of nature and humans to your own purposes.gt;gt;We conflate energy and power, the natural and the cultural, in language, but they are equally mixed as social fact at the rapids and portages. The energy system of the Columbia determined where humans would portage, but human labor created the actual route of the portage, and human social relations determined its final social form and outcome. The Dalles, per se, did not cause Ross's dilemma. Ross's humiliation was an incident of power. Human labor would later make the Dalles and the Cascades the sites of dams that produced energy--power; they were, however, long before this, sites at which humans contested over social power--the ability to gain advantage from the labor of others.gt;gt;Spatial arrangements matter a great deal in human history. They reveal the social arrangements that help produce them. The repeated conflicts at the Dalles and the Cascades revolved around a particular organization of space. Whites regarded the space at the Cascades and the Dalles as open, as culturally empty. Indians regarded it as full. In a space that brought together many different peoples, Indians expected gifts to mediate and smooth passages through this social maze. Too often whites replaced gifts with force; they resented what they perceived as theft and pillage. The space became uniquely violent.gt;gt;gt;gt;gt;IIgt;gt;gt;gt;Egt;xamining how hu

Our politics, our selves? : b liberalism, identity, and harm Peter Digeser Princeton, N.J.: Princeton University Press, Princeton University Press, Princeton, N.J., 1995
Is statecraft soulcraft? Should we look to our souls and selves in assessing the quality of our politics? Is it the business of politics to cultivate, shape, or structure our internal lives? Summarizing and answering the major theoretical positions on these issues, Peter Digeser formulates a qualified permission to protect or encourage particular forms of human identity. Public discourse on politics should not preclude talk about the role of reason in our souls or the importance of wholeness and community to our selves or the significance of autonomy for individuals. However, those who seek to place only their own conception of the self or soul within the reach of politics are as mistaken as those who would completely preclude such matters from the political realm. . In proposing this view, Digeser responds to communitarians, classical political rationalists, and genealogists who argue that liberal culture fragments, debases, or normalizes our selves. He also critically analyzes perfectionist liberals who justify liberalism by virtue of its ability to cultivate autonomy and authenticity, as well as liberal neutralists who wish to avoid altogether the problem of selfcraft. All these, he argues, fall short in some way in defining the extent to which politics should be concerned with the self.
