This is a watercolour by Susanna Moodie painted between 1832 and 1840, and entitled by her as "The First Mine in Ontario at Marmora, Hastings County," It is either the Blairton Ore mountain or the bank of the Crowe River where limestone was quarried for the blast furnaces. She did a second painting with the same title, both of which are stored in the National Archives in Ottawa. It is from this second painting that the Marmora Historical Foundation bases its logo of the three miners.
Susanna Moodie, nee Strickland, author, settler (born at Bungay, England, 6 Dec 1803; died at Toronto 8 Apr 1885) was the youngest in a literary family of whom Catharine Parr Traill and Samuel Strickland are best known in Canada. Her struggles as a settler, progressive ideas, attachment to the "best" of contemporary British values, suspicion of "yankee" influence in Canada, and her increasingly highly regarded book, Roughing it in the Bush, have made her a legendary figure in Canada.
