Of nursery rhymes.....

How do you like to go up in a swing,
Up in the air so blue?

Oh, I do think it the pleasantest thing
Ever a child can do!

Up in the air and over the wall,

Till I can see so wide,

River and trees and cattle and all
Over the countryside--

Till I look down on the garden green,
Down on the roof so brown--
Up in the air I go flying again,
Up in the air and down!

Robert Louis Stevenson
