In order to retain her juvenile readers for many years, Dodge created departments for different age groups. For Very Little Folks (1873–1897) was a page of simple stories printed in large type. The Puzzle Box contained riddles, math and word games. Young Contributors Department (begun in 1875) encouraged the writing skills of older children. The Agassiz Association was begun in 1885 to develop the awareness of nature, and the importance of conservation. Hundreds of Agassiz chapters were organized across the nation, and reports of activities were printed in the department.
