A child on a swing describes flying up over the garden wall to see rivers, cattle and rooftops spread out below, then dropping back down again. The repeated "up in the air" lines match the actual motion of a swing, so it works well said aloud while pushing one.
From A Child's Garden of Verses. See the whole collection.
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,
Rivers 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!
