In an article published in The Independent Ledger in Boston on February 26, 1781, the Academy wrote that “they request the Assistance of the Ingenious in every profession. Observations in Astronomy and Geography, will be of great use. Meteorological Observations and Experiments are much wanted.” By May 1781, the Academy had organized its activity into “subjects of study,” instructing that the “seventh class make meteorology their special object, observe the azimuth, meridional height, vertical direction and various phenomena of the Aurora borealis. . . .”
