The association was established to enable junior and senior electrical and mechanical engineering students to meet and discuss topics relating to engineering. Discussion topics included Portland Dry Dock, Current Literature, Suspension Bridges, and Wireless Telegraphy. In 1908, the electrical engineering students withdrew from the association and formed a local student chapter of the American Institute of Electrical Engineers.
