"The team of the "Grand Expedition," as it was optimistically named, was the first to send its findings on the newly annexed territory to the president, who received Dunbar and Hunter's detailed journals with pleasure. They include descriptions of flora and fauna, geology, weather, landscapes, and native peoples and European settlers, as well as astronomical and navigational records that allowed the first accurate English maps of the region and its waterways to be produced. Their scientific experiments conducted at the hot springs may be among the first to discover a microscopic phenomena still under research today."--Jacket.

Scottish-born William Dunbar (1750--1810) is recognized by Mississippi and Southwest historians as one of the most successful planters, agricultural innovators, explorers, and scientists to emerge from the Mississippi Territory. Despite his successes, however, history books abridge his contributions to America's early national years to a few passing sentences or footnotes. William Dunbar: Scientific Pioneer of the Old Southwest rectifies past neglect, paying tribute to a man whose life was driven by the need to know and the willingness to suffer in pursuit of knowledge. From the beginning, research, contemplation, and scholarship formed the template by which Dunbar would structure his life. His mother's insistence on education motivated him throughout his youth, and in 1771, he sailed to America, prepared to seize any and all opportunities. Settling in the Mississippi territory, Dunbar embarked on the endeavors that would soon gain him renown. He surveyed the boundary between Spanish West Florida and the United States and contributed heavily to the rise of cotton culture through his inventions and innovations in agricultural technology. In 1804, at the same time that Lewis and Clark were making their way up the Missouri River, President Thomas Jefferson appointed Dunbar -- now a fellow member of the prestigious American Philosophical Society -- to lead a similar exploration of the southern Louisiana Purchase territory. The 103-day expedition captured the imagination of Americans looking to move westward and yielded the first information about the geographical, geological, and meteorological characteristics of the old Southwest. Arthur H. DeRosier Jr. traces Dunbar's life from his ambition as a youth to his development into a man recognized by his contemporaries as a leader in many scientific fields. Drawing upon the private journal of Dunbar's granddaughter Virginia Dunbar McQueen and neglected historical annals, William Dunbar examines Dunbar's public and private life, the scope of his interests, and the lasting contributions he left to a country and people he loved.

The Historical Dictionary of the American Frontier covers early Euro-American exploration and development of frontiers in North America but not only the lands that would eventually be incorporated into the Unites States it also includes the multiple North American frontiers explored by Spain, France, Russia, England, and others. The focus is upon Euro-American activities in frontier exploration and development, but the roles of indigenous peoples in these processes is highlighted throughout. The history of this period is covered through a chronology, an introductory essay, and an extensive bibliography. The dictionary section has over 300 cross-referenced entries on explorers, adventurers, traders, religious orders, developers, and indigenous peoples. This book is an excellent access point for students, researchers, and anyone wanting to know more about the development of the American frontier.

Cameron Strang takes American scientific thought and discoveries away from the learned societies, museums, and teaching halls of the Northeast and puts the production of knowledge about the natural world in the context of competing empires and an expanding republic in the Gulf South. People often dismissed by starched northeasterners as nonintellectuals--Indian sages, African slaves, Spanish officials, Irishmen on the make, clearers of land and drivers of men--were also scientific observers, gatherers, organizers, and reporters. Skulls and stems, birds and bugs, rocks and maps, tall tales and fertile hypotheses came from them. They collected, described, and sent the objects that scientists gazed on and interpreted in polite Philadelphia. They made knowledge. Frontiers of Science offers a new framework for approaching American intellectual history, one that transcends political and cultural boundaries and reveals persistence across the colonial and national eras. The pursuit of knowledge in the United States did not cohere around democratic politics or the influence of liberty. It was, as in other empires, divided by multiple loyalties and identities, organized through contested hierarchies of ethnicity and place, and reliant on violence. By discovering the lost intellectual history of one region, Strang shows us how to recover a continent for science.

A definitive scholarly edition of the correspondence and papers of Thomas Jefferson This volume opens soon after the start of the second session of the Eighth Congress and ends a few days after the session closes. During the period, Jefferson receives twice as many documents as he writes. He sits for portraits by Charles Févret de Saint-Mémin and Rembrandt Peale. The nation endures an extreme winter. William Dunbar begins to send information from the exploration of the Ouachita River. Acts of Congress create new territories and give Orleans Territory an assembly and a path to statehood. The Senate ratifies a treaty to acquire an estimated 50 million acres of land from the Sac and Fox tribes. Levi Lincoln resigns, Robert Smith asks to succeed him as attorney general, and Jefferson seeks a new secretary of the navy. Jefferson and vice-presidential candidate George Clinton receive 162 electoral ballots against 14 for their opponents, Charles Cotesworth Pinckney and Rufus King. Napoleon is crowned emperor of the French, and Spain declares war on Great Britain. The Senate acquits Samuel Chase of eight articles of impeachment. Jefferson prepares his inaugural address and is sworn into office for his second term on 4 March. He refuses to consider serving a third term.

In The Big Muddy, the first long-term environmental history of the Mississippi, Christopher Morris offers a brilliant tour across five centuries as he illuminates the interaction between people and the landscape, from early hunter-gatherer bands to present-day industrial and post-industrial society. Morris shows that when Hernando de Soto arrived at the lower Mississippi Valley, he found an incredibly vast wetland, forty thousand square miles of some of the richest, wettest land in North America, deposited there by the big muddy river that ran through it. But since then much has changed, for the river and for the surrounding valley. Indeed, by the 1890s, the valley was rapidly drying. Morris shows how centuries of increasingly intensified human meddling--including deforestation, swamp drainage, and levee construction--led to drought, disease, and severe flooding. He outlines the damage done by the introduction of foreign species, such as the Argentine nutria, which escaped into the wild and are now busy eating up Louisiana's wetlands. And he critiques the most monumental change in the lower Mississippi Valley--the reconstruction of the river itself, largely under the direction of the Army Corps of Engineers. Valley residents have been paying the price for these human interventions, most visibly with the disaster that followed Hurricane Katrina. Morris also describes how valley residents have been struggling to reinvigorate the valley environment in recent years--such as with the burgeoning catfish and crawfish industries--so that they may once again live off its natural abundance. Morris concludes that the problem with Katrina is the problem with the Amazon Rainforest, drought and famine in Africa, and fires and mudslides in California--it is the end result of the ill-considered bending of natural environments to human purposes.

After the congressional session ends, Jefferson leaves Washington and goes home to Monticello, where his ailing daughter Mary dies on 17 April. Among the letters of condolence he receives is one from Abigail Adams that initiates a brief resumption of their correspondence. While in Virginia, Jefferson immerses himself in litigations involving land. Back in the capital, he finds that he must reconcile differing opinions of James Madison and Albert Gallatin to settle a claim for diplomatic expenses. He corresponds with Charles Willson Peale about modifications to the polygraph writing machine. He prepares instructions for an expedition to explore the Arkansas and Red Rivers. William Clark and Meriwether Lewis send him maps and natural history specimens from St. Louis. Alexander von Humboldt visits Washington. News arrives that a daring raid led by Stephen Decatur Jr. has burned the frigate Philadelphia to deprive Tripoli of its use. Jefferson is concerned that mediation by Russia or France to obtain the release of the ship’s crew could make the United States appear weak. Commodore Samuel Barron sails with frigates to reinforce the squadron in the Mediterranean. Jefferson appoints John Armstrong to succeed Robert R. Livingston as minister to France and attempts to persuade Lafayette to move to Louisiana. In Paris, Napoleon is proclaimed Emperor of the French. Jefferson has “brought peace to our Country and comfort to our Souls,” John Tyler writes from Virginia.
