John,
I've just been to fetch the book and read the poem again to see if I can help you out...
Since the poem is based on anagrams of poets' names I'm pretty certain
poets mar satanic cargo is an anagram of
something; the trouble is, there are oodles of 'em for that phrase!
I've looked at an internet anagram site and quite like ''pragmatists earn cocoa" - but I'm sure that's not it
Try a search yourself and you might recognise what you meant when you first wrote it! Sorry I can't do any more without getting inside your head (now,
there's an interesting place!
)
