In subsequent editions the paper entitled Kindergarten Culture, was added, and in 1878 the plates of The Paradise of Childhood were prefaced with a brief text and published in separate form as A hand-book for the Kindergarten, the contents of which were after wards incorporated with the Paradise during many editions. For a quarter of a century this work has been accepted as the only single book furnishing in brief an outline of both the theory and practice of the kindergarten. In 1876 it received honorable mention at the Philadelphia Centennial Exhibition as being the first illustrated guide to the kindergarten ever published in the English language.
