Sorry, Jj, we crossed. What's your hitch? Like PM, I found the matching up one of the most satisfying parts.

[ProfessorMaisie]

35 - Is just an anagram but the 'poetic' reference is a bit obscure (Milton's spelling regarding Siberians).

[JJ109]

Thanks NAC no problems - I'll enjoy that part tomorrow.

[ProfessorMaisie]

3 - def is 'Return' + 2x initial letters + abbrev 'house' ['drop' gatherings] - your U is wrong, Matakari.

[ProfessorMaisie]

Matakari - you have a lot of wrong letters, these are in -
10 + 15 (JJ has given the right answers)
24[all wrong]+ 30[all wrong]+ 35['y' is wrong](I've given some hints)
2d (chelle7272 has given the right answer).
3['u' is wrong]
22 (aelmpvw has given the right answer).

[Neveracrossword]

PM, you've got far more patience than I have!. I told Matakari earlier that all his letters were wrong, but that's as far as I went. Mind you, he'd already been given some answers and corrections by then.

[ProfessorMaisie]

...just noticed that JJ also gave the right answer for 3 (sorry I missed it jj, but it's quite a busy thread).

[ProfessorMaisie]

...sorry, Neveracrossword - I must have missed that one too.

[Matakari]

My thanks to all for the answers and hints! I'll be getting back to this puzzle later on. Stay safe, all!
