Voyages from Montreal Through the Continent of North America to the Frozen and Pacific Oceans - Vol. I by Alexander Mackenzie. This book is a reproduction of the original book published in 1902 and may have some imperfections such as marks or hand-written notes.

From Streeter: This is the classic account of Mackenzie's journey from Fort Chipeway on Lake Athabasca, here called Lake of the Hills, down the river which bears his name to the sea and back in 1789. Even more important is the journal of the journey from the "New Establishment" on the Peace River to the Pacific Ocean (actually to "Mackenzie's Rock" on Dean Channel), and the return to Fort Chipeway. This journey marked the first crossing of the continent by white men.
