In The Practice of Her Profession, Susan Butlin draws on unpublished letters and family memoirs to recount Carlyle's personal and professional life. She explores Carlyle's artistic influences, her relationships with artist colleagues and encounters with the cultural worlds of Paris, New York, and early twentieth-century Canada, and provides a detailed examination of Carlyle's paintings. Butlin's vivid description of the artistic life of women of this era, from access to art training to the important role of women's art societies, introduces readers to Carlyle's many accomplished contemporaries - Helen McNicoll, Mary Reid, Laura Muntz, Sarah Holden, Sydney Tully, Elizabeth McGillivray Knowles, and others.
