A Route of Evanescence
With a revolving Wheel--
A Resonance of Emerald--
A Rush of Cochineal--
And every Blossom on the Bush
Adjusts its tumbled Head--
The mail from Tunis, probably,
An easy Morning's Ride--
Dickinson feels as though the scene is as foreign and mysterious as Tunis (also called Tunisia), a country in northeast Africa.
