In August 1912, a loan was made to the Academy of $6,000 by a friend, Miss Ida Mason. The money was used to build Mason Cottage which was built as a home for a master and his family. It was later used as a dormitory. The plans for the building were drawn by George Champney, a 1902 graduate of Dummer Academy, who also designed the old Byfield Parish Church in 1931.
Mason Cottage was torn down in 1997 to make room for the new Math and Science building. The photographs below were taken of Mason Cottage circa 1915. In one you will notice the roof of Peirce Hall to the left in the distance. The interior image is of the Mason Cottage living room.
