No man can roan or inhabit the Canadian North without it affecting him, and the artist, because of his constant habit of awareness and his discipline in expression, is perhaps more understanding of its moods and spirit than others are. He is thus better equipped to interpret it to others, and then, when her has become one with its spirit, to create living works in their own right, by using forms, colors, rhythms and moods, to make a harmonious home for the imaginative and spiritual meaning it has evoked in him.
