"When the landscape had struck him especially by its general planes, he flung it on the canvas in those marvelous sketches which the artist refused to carry on further because he had nothing to add to this massy statement; at other times he insinuates himself into the details as exhaustively as possible and refines on his work to the utmost limits of execution. In this way the career of Daubigny is based on the simple and truthful art-theory that the handling of a picture ought to reflect the mood felt."
