Adams Academy was akin to Exeter and Andover, playing against many of the same teams. Adams was a feeder school for Harvard. A trip to the Quincy Historical Society (Quincy, Mass.) may yield the exact date and possible identities of the sitters. The society has many of the Adams records, inclusive of older sporting photos. The academy opened in 1872 and ceased operation in 1908.
Adams played the Boston Game early on and by 1876 appears to be playing the American Rugby Game, and the American Collegiate Game by 1882.
