Where swift-running, cool, clear waters run their course between lofty, green cathedral walls of giant western fir and spruce, where merganser ducks fly fast and low over swirling deeps and white-foamed rapids, where the silent sea-eagle soars regally over all, this is the haunt of Canada's foremost proponent of the ancient art of fly-fishing - Vancouver Island's magistrate-author, Roderick Haig-Brown. A philosopher of men and fish and their natural environment, Mr. Haig-Brown has recorded his factual and poetic observations of the ways of the living world in 22 various books and scores of other writings. Considered one of North America's leading authors on fly-fishing for steelhead trout and other game fish, Haig-Brown is also a highly-reputed authority on the mechanics and aesthetics of the conservation of natural resources. In 25 years as magistrate and judge in northern Vancouver Island, he has earned deep and widespread respect for his practical and tolerant approach to the daily problems of the modern world. From his place in the scheme of things - down by the river's edge, on the judicial bench, with his wife and family, at work in his well-used library - Roderick Haig-Brown sees the world in wide perspective, a penetrating, overall view made all the more clear and candid by the self-chosen, inconspicuous but ever alert role that is the mark of true fly-fishermen the wide world over.
