In this true story of adventure, author Jack Nisbet re-creates the life and times of David Thompson-fur trader, explorer, surveyor, and mapmaker. From 1784 to 1812, Thompson explored western North America and was the first to chart the entire length of the Columbia River. His field journals provide the earliest written accounts of the natural history and indigenous cultures of the region, and Nisbet uses them to guide his own discovery of the Northwest Territory some two centuries later.

The awe-inspiring story of explorer David Thompson, whose expeditions helped shape western North America In this true story of adventure, author Jack Nisbet re-creates the life and times of David Thompson—fur trader, explorer, surveyor, and mapmaker. From 1784 to 1812, Thompson explored western North America, and his field journals provide the earliest written accounts of the natural history and indigenous cultures of the what is now British Columbia, Alberta, Montana, Idaho, Washington, and Oregon. Thompson was the first person to chart the entire route of the Columbia river, and his wilderness expeditions have become the stuff of legend. Jack Nisbet tracks the explorer across the content, interweaving his own observations with Thompson’s historical writings. The result is a fascinating story of two men discovering the Northwest territory almost two hundred years apart.

In this history of the black peasants of Amazonia, Oscar de la Torre focuses on the experience of African-descended people navigating the transition from slavery to freedom. He draws on social and environmental history to connect them intimately to the natural landscape and to Indigenous peoples. Relying on this world as a repository for traditions, discourses, and strategies that they retrieved especially in moments of conflict, Afro-Brazilians fought for autonomous communities and developed a vibrant ethnic identity that supported their struggles over labor, land, and citizenship. Prior to abolition, enslaved and escaped blacks found in the tropical forest a source for tools, weapons, and trade--but it was also a cultural storehouse within which they shaped their stories and records of confrontations with slaveowners and state authorities. After abolition, the black peasants' knowledge of local environments continued to be key to their aspirations, allowing them to maintain relationships with powerful patrons and to participate in the protest cycle that led Getulio Vargas to the presidency of Brazil in 1930. In commonly referring to themselves by such names as "sons of the river," black Amazonians melded their agro-ecological traditions with their emergent identity as political stakeholders.

Discovery of the sources of the Mississippi River : Summary Narrative of an Exploratory Expedition to the Sources of the Mississippi River in 1820. Discovery of the sources of the Mississippi River : Summary Narrative of an Exploratory Expedition to the Sources of the Mississippi River in 1820. Resumed and Completed, by the Discovery of its Origin in Itasca Lake, in 1832 The following pages embrace the substance of the narratives of two distinct expeditions for the discovery of the sources of the Mississippi River, under the authority of the United States. By connecting the incidents of discovery, and of the facts brought to light during a period of twelve years, unity is preserved in the prosecution of an object of considerable importance in the progress of our geography and natural history, at least, from the new impulse which they received after the treaty of Ghent. Geographers deem that branch of a river as its true source which originates at the remotest distance from its mouth, and, agreeably to this definition, the combined narratives, to which attention is now called, show this celebrated stream to arise in Itasca Lake, the source of the Itasca River. Owing to the time which has intervened since these expeditions were undertaken, a mere revision of the prior narrations, in the journal form, was deemed inexpedient. A concise summary has, therefore, been made, preserving whatever information it was thought important to be known or remembered, and omitting all matters not partaking of permanent interest.

NEW YORK TIMES BESTSELLER • The harrowing story of one of the great feats of exploration of all time and its complicated legacy—from the New York Times bestselling author of The River of Doubt and Destiny of the Republic A BEST BOOK OF THE YEAR: THE WASHINGTON POST • GOODREADS "A lean, fast-paced account of the almost absurdly dangerous quest by [Richard Burton and John Speke] to solve the geographic riddle of their era." —The New York Times Book Review For millennia the location of the Nile River’s headwaters was shrouded in mystery. In the 19th century, there was a frenzy of interest in ancient Egypt. At the same time, European powers sent off waves of explorations intended to map the unknown corners of the globe – and extend their colonial empires. Richard Burton and John Hanning Speke were sent by the Royal Geographical Society to claim the prize for England. Burton spoke twenty-nine languages, and was a decorated soldier. He was also mercurial, subtle, and an iconoclastic atheist. Speke was a young aristocrat and Army officer determined to make his mark, passionate about hunting, Burton’s opposite in temperament and beliefs. From the start the two men clashed. They would endure tremendous hardships, illness, and constant setbacks. Two years in, deep in the African interior, Burton became too sick to press on, but Speke did, and claimed he found the source in a great lake that he christened Lake Victoria. When they returned to England, Speke rushed to take credit, disparaging Burton. Burton disputed his claim, and Speke launched another expedition to Africa to prove it. The two became venomous enemies, with the public siding with the more charismatic Burton, to Speke’s great envy. The day before they were to publicly debate,Speke shot himself. Yet there was a third man on both expeditions, his name obscured by imperial annals, whose exploits were even more extraordinary. This was Sidi Mubarak Bombay, who was enslaved and shipped from his home village in East Africa to India. When the man who purchased him died, he made his way into the local Sultan’s army, and eventually traveled back to Africa, where he used his resourcefulness, linguistic prowess and raw courage to forge a living as a guide. Without Bombay and men like him, who led, carried, and protected the expedition, neither Englishman would have come close to the headwaters of the Nile, or perhaps even survived. In River of the Gods Candice Millard has written another peerless story of courage and adventure, set against the backdrop of the race to exploit Africa by the colonial powers.
