I am aware of only one Riker juvenile series. This six volume series was also published by S. Colman, a Boston publisher as "Grandmother's New Juvenile Books". In Colman advertisements for this series it notes it was edited by Mrs. Colman. Interestingly there must have been a relationship between the two firms since the Riker book below has a page that advertises Colman books.
