As usual, I've ground to a halt after a promising start. I have the message from the Across clues (albeit not having solved them all by any means), but it will have to wait to be implemented.
I think I have the first word of the Downs message, which led me to think of a famous poem by a famous poet, but the second word isn't appearing.
Overall, I've got quite a lot of the NW corner, but not much else. Is 1Down entered jumbled? Hints on 6ac and 19ac would be welcome.
Lots still to do!!
