Fine as the dust of plumy fountains blowing
Across the lanterns of a revelling night,
The tiny leaves of April's earliest growing
Powder the trees—so vaporously light,
They seem to float, billows of emerald foam
Blown by the South on its bright airy tide,
Seeming less trees than things beatified,
Come from the world of thought which was their home.

For a while only. Rooted strong and fast,
Soon will they lift towards the summer sky
Their mountain-mass of clotted greenery.
Their immaterial season quickly past,
They grow opaque, and therefore needs must die,
Since every earth to earth returns at last.
