To a fifth of the wind, that pierces us most,
Add the name of a beast by shepherds oft lost, 
The name of a river by Cambrians fam'd, 
With the third of a name by Britons oft blam’ d; 
Join the fifth of a name oft in pillory shown; --
These will instantly give you the name of my town.

Which American town is referred to in the riddle?
