Nature Study in Elementary Schools, Readers/Google Books

First Reader: The title mentions that this is a first reader; however, it looks a bit advanced for a first reader, more like a second grade leveled reader. Take a look to determine for yourself.

Second Reader, Myths, Stories, and Stories: Again, seems advanced for second grade, more like a third grade reader.
