Spyri is the Swiss writer whose story for children, Heidi, is known all over the world. Her psychological insight into the child mind, her humor, and her ability to enter into childish joys and sorrows give her books attraction and lasting value. The book begins: On the east side of the city of Karlsruhe there is a lovely park and under the shade of its linden trees a gentleman slowly paced back and forth every afternoon. The other promenaders always glanced at him in sympathy as he passed by, for it touched their hearts to see how his little companion strove to help him along. Certainly he must be very ill, he walked so very slowly, and although he always leaned heavily on a strong cane which he carried in his right hand, he found it necessary to see the further support of the little girl's should with his left.
