This series consists of notes and drafts of speeches. MacMillan was a prolific writer on political and social subjects. Much of his work was written to be delivered by Sir Arthur Currie, who, both as a veteran and as Principal of McGill, was frequently called on to address Founder's Day gatherings as well as Armistice Day ceremonies. MacMillan also spoke at many affairs for which he received laudable reviews. Many of his notes and drafts are untitled and undated so that it not always possible to know if they were written for Sir Arthur or Dr. MacMillan, himself, as both men were veterans and connected with McGill.The detailed list of MacMillan's own notes in File 1057-2-39 gives some idea of the wide range of subjects about which he wrote.
