Spectator 2150

[Farrwest]

Really stuck on this one. The answer to 1d would be appreciated.
'Knots disfigured the birch in intervals (13 two words) T???E??????E?' (note - one word in the clue could be superfluous)
'

[Lie-in King]

Toties quoties (Lat. "on each occasion"; "at intervals") (?)

Sorry, I can see 2 x 'ties' for 'knots' but am unable to parse the rest - if I had the whole crossword, I might make a better fist of it

[Farrwest]

Thank you Lie-In King. This has to be one of the hardest xword I've ever tackled. A long way to go yet!

[novalis]

Timber hitches.
Anagram of the birch contained in times

[hankir]

The answer is a kind of knot:
a knot used to attach a single length of rope to a cylindrical object

It is 6,7.
I have not quite worked out the parsing but anagram of "the birch" is involved.
I have completed the puzzle but parsing of a couple remains to be deciphered.
The quote is essential to solving the italics clues.
It is time to sleep where I am, so good night.

Farrwest- persevere it's a good un.

Email me if you need a nudge

Time exposures?

[djawhufc]

Sorry Farr- I forgot to say the answer to this one is timber hitches (anagram the birch inside times)

[Lie-in King]

Apologies, Farrwest - I completely mucked this one up & never having heard of a 'timber hitch' didn't help!

[Farrwest]

Thanks all. Woke up this am (in Canada) to find a new answer to 1d which will give me heart to carry on!
