Kleine was a philologist, his lessons not held in contemporary language, and it is not known for certain all subjects Busch and his friend were taught. Busch did learn elementary arithmetic from his uncle, although science lessons might have been more comprehensive, as Kleine, like many other clergymen, was a beekeeper, and published essays and textbooks on the subject, – Busch demonstrated his knowledge of bee-keeping in his future stories. Drawing, and German and English poetry, were also taught by Kleine.
