I have modernized the language somewhat.
When our "good neighbors" ride if I think right
Some mounted on ragweed and some on a bean,
All tripping in troupes from the twilight;
Some saddles on a she-ape arrayed in green,
Some riding on hempstalks rising on high,
The King of Faerie with his court and the Elf-Queen
With many an eldritch incubus was riding that night.
