A note on #21 This tree is known here as a tamarack. I think larch is more European or Asian. They get a brilliant yellow in the fall before they lose their needles. They grow mostly in wet swampy type areas. I guess they like wet feet.

A note on #5 There is a quite entertaining sequence in the Disney film "Fantasia" of Mickey Mouse laboring to the music of The Sorcerer's Apprentice.

I hope I have not spoiled anything for anyone else.

Cheers

[Edit: Adri's response to Sgt. Joe got posted while I was compiling this, so I've added something about "convey" as a postscript...]

I very much doubt anyone else will have tackled the puzzle, so thanks to Sgt. Joe for saving me the trouble of offering up the answers once Adri had posted his [excellent] effort! Unfortunately, I suspect we four are the only folks keeping this alive at present...

I was going to post explanations for some of the more awkward clues and comments such as that note about #5 and Fantasia; much of that is also covered above...

However :-)

Firstly, on the subject of obscure words -- I managed to arrange two of the words I expected to be troublesome so that they had three check letters, but 24 down was a failure in that sense. Sorry about that :-(

If called upon for a hint for COOMB I might have suggested finding the Welsh word for valley which almost certainly has the same roots as the [Cornish?] word that often ends up in "West Country" place names as COMBE (as observed by Mark) e.g. Ilfracombe...

Similarly, for 32 across my supplementary would have been "Geoff _____, World Cup hat-trick scorer"

As for 11 across, I tossed up between using CADGE and CADRE. I found it easier to make a short clue for CADGE :-) -- sorry about that...

Other notes:

Regarding 31 across -- I expected HURST; if HIRST is an American spelling for the same word, fair enough (but I couldn't find it defined thus on a cursory search) Again, as Mark noted, it shows up in place names - one example is Sandhurst, location of the Royal Military Academy in the UK. (A clue for HIRST might have been "Damien _____, artist")

Thanks to Sgt. Joe for mentioning tamarack (Larix laricina), which I've just looked up. That was an interesting half-hour or so of research[*1] :-) Apparently it is usually found in North-eastern America, Alaska and Canada (and can survive very cold temperatures, as can Siberian Larch (Larix Sibirica)!); other larches (for instance, Larix decidua) are found elsewhere in the USA and worldwide.

Apparently, tamarack is a native Algonquian word that means “wood for snowshoes” (which I thought might interest Adri given his post about 'Friese doorlopers' :-)

As for Larch trees in the UK, a sad note: Forestry Scotland will have removed all Larch trees from south-western Scotland forests within the next 10 years to try to stop the spread of a tree-killing disease (Phytophthora ramorum). Similar fellings are also taking place across Wales, and [more local to me] Japanese Larch trees have been felled in the Sheffield area for the same reason :-(

On a more humorous note, whenever I think of Larch I remember the Monty Python slide-show - "Number 1, the larch..."

In closing, I'm glad the puzzle gave some fun, and once again a big "Well done!" to Adri, especially given that no "looking up" was done!

Cheers - Al.

P.S. re "convey" - it has the same root as "convoy" but takes the carry, transmit or communicate senses rather than the escort or grouped transport senses. The word ""conveyance" means a vehicle or (amongst other things) the transfer of property or the documents for such a purpose...

[*1] I found the following interesting: https://extension.unh.edu/blog/2022/10/autumn-gold-tamarack and https://a-z-animals.com/blog/larch-vs-tamarack/...

Al, a short note: Ah, of course! The Larch and the accompanying sketch.

Thank you! And many thanks for the great puzzle! And although I'm surrounded by scores of dictionaries and the fact that I have participated in the making of many dictionaries, i.e. writing programs and administrating/converting dictionary versions, and even compiled a (Dutch) Scrabble dictionary some 15 years ago (probably one of these ones pictured - they didn't hand me the final product) I found that it was time to test my knowledge without using anything but my brain, without being disturbed by TV, music or even the computer. Just as easy, I could have used the computer to search for anything that I wanted, trying to solve the puzzle, but in fact I could resist the temptation.

Also, when I posted my answers, I didn't know if I would get some more hints; maybe I would have waited a day and then would have started searching for answers, using the computer, just like that, because it's the easiest thing to do.

Al, thanks for this wonderful experience.

I see, and thanks, my English to Dutch dictionary lookup tool doesn't list the word 'conveyance' .

Adri

All, the weekends are not forgotten, just been busy with scanning documents, more tweaking and extending than actually writing (computer) programs, continuing doing my record inventory, and oh yeah, also doing puzzles :-) - not setting any at the moment.

(I was using the word 'compiling' before, I didn't know about the term 'setting a puzzle'.)

Al, re "overdracht": we have many Dutch words ending in -dracht; in case you're wondering, I will list a few. 'Dracht' is derived from the verb 'dragen' = to wear/bear/carry/support/endure/sustain
klederdracht = traditional costume/dress
haardracht = hair style
eendracht = harmony/concord [proverb 'eendracht maakt macht' = unity is strength]
opdracht = assignment [e.g. programmeeropdracht = programming assignment]
toedracht = circumstances [e.g. that what caused the accident]
voordracht = lecture, recital

PS Outside it's over 30°C at the moment (17:00 local time).

Hi there! Today - in this taskless weekend, or maybe soon to be taskless - I found a small puzzle with matches.

Below you'll find 16 matches, arranged so that they form 5 squares.

Your job is to rearrange the figure (obviously) so that four squares of the same size remain.
You should do this by moving two matches only (keeping the same 16 matches).
You can't place two matches at the same spot, you cannot bend or break them in pieces.

(If you want to play this with sewing pins with a rounded head instead of matches, that's okay, of course. )

Good luck!
Adri
EDIT: No, you cannot put three matches at the same position.
