Combined Unabridged Editions, Two Books in One,
by Selma Lagerlöf, Sweden.
Cover illustration from the original 1917 edition.
These two books were written for use in schools as "supplementary reading," with the special idea of introducing educational and entertaining subjects to children from the ages of nine to eleven. The books were adopted in the public schools of Sweden, but adults have found them books of permanent value.
These are the adventures of Nils, a young boy who flies across Sweden on the back of a goose, visiting interesting places and meeting fascinating people. For all ages.
