A little midge sung a song around a person, who was sleeping in the bed at night. > _How does the little busy me > **Improve each shady hour** > By setting on your nose or knee > As if upon a flower_ This is a short story from the novel "Little Old Mrs Pepperpot" I couldn't understand the meaning "Improve each shady hour". Does it mean "get light"? Could you teach me the meaning?
