What's the difference between a fen and a dale? Are these words used precisely at all?
My question comes from Kipling’s poem The Spirit of England; if you'll notice, each couplet, plain and hill, towns and downs seem to be opposing, and I was wondering if that were true for woodland and fen and dale.
I summon to battle from plain and hill,
From woodland and fen and dale,
From my reeking towns and greyhound downs
My men to be cast in the scale.
