The records of the Secretary-Treasurer's Office include public relations material, correspondence with stockholders, and annual report production. Some material was retained from the records of the secretary and the treasurer prior to the merger, but the bulk of that material can be found as part of Subseries III: Boston Office Records.

During his term as Secretary-Treasurer, J. Roland Ackroyd maintained what he called a historical file. This included historic documents, articles relating to company history, and contemporary material that he felt would be of historical significance.

A small amount of additional material came from the office of Vice-President--Finance C. L. Nielsen.
