446 p. At the age of 68 M. J. Lorraine explored the Columbia River from its source to its mouth alone in a rowboat. He was the second person, after David Thompson in 1811, to make this unbroken voyage in one boat, which he had built himself. The book describes his preparations for the journey and experiences along the way as well as the country through which he travelled, and is illustrated with a number of black-and-white photographs he took en route.
