Capturing the essence of the origin and evolution of the so-called "degeneracy debates," over whether the flora and fauna of America (including Native Americans) were naturally weaker and feebler than species elsewhere in the world, this book chronicles Thomas Jefferson's efforts to counter French conceptions of American degeneracy, culminating in his sending of a stuffed moose to Buffon

Is there anything new to say about Thomas Jefferson and slavery? The answer is a resounding yes. Master of the Mountain, Henry Wiencek's eloquent, persuasive book—based on new information coming from archaeological work at Monticello and on hitherto overlooked or disregarded evidence in Jefferson's papers—opens up a huge, poorly understood dimension of Jefferson's world. We must, Wiencek suggests, follow the money. So far, historians have offered only easy irony or paradox to explain this extraordinary Founding Father who was an emancipationist in his youth and then recoiled from his own inspiring rhetoric and equivocated about slavery; who enjoyed his renown as a revolutionary leader yet kept some of his own children as slaves. But Wiencek's Jefferson is a man of business and public affairs who makes a success of his debt-ridden plantation thanks to what he calls the "silent profits" gained from his slaves—and thanks to a skewed moral universe that he and thousands of others readily inhabited. We see Jefferson taking out a slave-equity line of credit with a Dutch bank to finance the building of Monticello and deftly creating smoke screens when visitors are dismayed by his apparent endorsement of a system they thought he'd vowed to overturn. It is not a pretty story. Slave boys are whipped to make them work in the nail factory at Monticello that pays Jefferson's grocery bills. Parents are divided from children—in his ledgers they are recast as money—while he composes theories that obscure the dynamics of what some of his friends call "a vile commerce." Many people of Jefferson's time saw a catastrophe coming and tried to stop it, but not Jefferson. The pursuit of happiness had been badly distorted, and an oligarchy was getting very rich. Is this the quintessential American story?

In this sweeping adventure story, Stephen E. Ambrose, the bestselling author of D-Day, presents the definitive account of one of the most momentous journeys in American history. Ambrose follows the Lewis and Clark Expedition from Thomas Jefferson's hope of finding a waterway to the Pacific, through the heart-stopping moments of the actual trip, to Lewis' lonely demise on the Natchez Trace. Along the way, Ambrose shows us the American West as Lewis saw it -- wild, awsome, and pristinely beautiful. Undaunted Courage is a stunningly told action tale that will delight readers for generations. In 1803 President Thomas Jefferson selected his personal secretary, Captain Meriwether Lewis, to lead a voyage up the Missouri River to the Rockies, over the mountains, down the Columbia River to the Pacific Ocean, and back. Lewis was the perfect choice. He endured incredible hardships and saw incredible sights, including vast herds of buffalo and Indian tribes that had had no previous contact with white men. He and his partner, Captain William Clark, made the first map of the trans-Mississippi West, provided invaluable scientific data on the flora and fauna of the Louisiana Purchase territory, and established the American claim to Oregon, Washington, and Idaho. Ambrose has pieced together previously unknown information about weather, terrain, and medical knowledge at the time to provide a colorful and realistic backdrop for the expedition. Lewis saw the North American continent before any other white man; Ambrose describes in detail native peoples, weather, landscape, science, everything the expedition encountered along the way, through Lewis's eyes. Lewis is supported by a rich variety of colorful characters, first of all Jefferson himself, whose interest in exploring and acquiring the American West went back thirty years. Next comes Clark, a rugged frontiersman whose love for Lewis matched Jefferson's. There are numerous Indian chiefs, and Sacagawea, the Indian girl who accompanied the expedition, along with the French-Indian hunter Drouillard, the great naturalists of Philadelphia, the French and Spanish fur traders of St. Louis, John Quincy Adams, and many more leading political, scientific, and military figures of the turn of the century. This is a book about a hero. This is a book about national unity. But it is also a tragedy. When Lewis returned to Washington in the fall of 1806, he was a national hero. But for Lewis, the expedition was a failure. Jefferson had hoped to find an all-water route to the Pacific with a short hop over the Rockies-Lewis discovered there was no such passage. Jefferson hoped the Louisiana Purchase would provide endless land to support farming-but Lewis discovered that the Great Plains were too dry. Jefferson hoped there was a river flowing from Canada into the Missouri-but Lewis reported there was no such river, and thus no U.S. claim to the Canadian prairie. Lewis discovered the Plains Indians were hostile and would block settlement and trade up the Missouri. Lewis took to drink, engaged in land speculation, piled up debts he could not pay, made jealous political enemies, and suffered severe depression. High adventure, high politics, suspense, drama, and diplomacy combine with high romance and personal tragedy to make this outstanding work of scholarship as readable as a novel.
