Analysis of Tall Ambrosia

Among the signs of autumn I perceive
The Roman wormwood (called by learned men
Ambrosia elatior, food for gods,—
For to impartial science the humblest weed
Is as immortal once as the proudest flower—)
Sprinkles its yellow dust over my shoes
As I cross the now neglected garden.
—We trample under foot the food of gods
And spill their nectar in each dropp of dew—
My honest shoes, fast friends that never stray
Far from my couch, thus powdered, countryfied,
Bearing many a mile the marks of their adventure,
At the post-house disgrace the Gallic gloss
Of those well dressed ones who no morning dew
Nor Roman wormwood ever have been through,
Who never walk but are transported rather—
For what old crime of theirs I do not gather.
