G.M. Hopkins, "Spring"

Nothing is so beautiful as Spring —
         When weeds in wheels, shoot long and lovely and lush;
         Thrush's eggs look little low heavens, and thrush
Through the echoing timber does so rinse and wring
The ear, it strikes like lightnings to hear him sing;
         The glassy peartree leaves and blooms, they brush
         The descending blue; that blue is all in a rush
With richness; the racing lambs too have fair their fling.

What is all this juice and all this joy?
         A strain of the earth's sweet being in the beginning
In Eden garden. — Have, get, before it cloy,
         Before it cloud, Christ, lord and sour with sinning,
Innocent mind and Mayday in girl and boy,
         Most, O maid's child, thy choice and worthy the winning.
