## Enigmatic Variations 894 Gas Control by Shark

Posted by Colin Blackburn on January 7th, 2010

Oddly, I had just completed a Shark puzzle in Magpie before downloading the EV and discovering that it too was a Shark. I found the Magpie puzzle relatively easy but this one proved more difficult. Some of the clues had me using electronic aids (ACS and Chambers on the iPod) to find the answers that fitted and then working backwards. That’s not something I like doing but I did find a good handful of clues that tricky.

Anyway, after getting almost all the answers I finally teased out the message from the letters that the subsidiary indications led to. Actually, the preamble stated that the subsidiary indications contained an extra letter. This is point aside, the message was JOIN UP TWO SYMMETRICAL LETTER STRINGS IN GREEN. The preamble suggested comparing the grid in two halves. It also suggested the joining-up should be continuous and not overlap.

I have to admit to staring at the grid for a good while looking for patterns and trying to think through the various elements. I also tried to think about what Gas Control might mean without much success. Green was clearly significant, but not significant enough for my synapses to fire. The two halves were clearly significant. A bit more grid staring and I saw that the lower letters either side of the central vertical divide had a similarity. In fact the word TREE was in there. Doh! It’s Christmas!

A quick scan revealed several letters in the grid mirrored about the central vertical, starting with a C at the top (these are shown in red in the grid below). On the left they spelled out CHRISTMAS TREE (on the right the slightly less successful CHRISIMAS TREE). Joining these letters up revealed the classic shape of a Christmas tree. I have drawn the line on the grid below how I imagine it should be though it is possible the pot for the treemight be drawn a few ways.

I still don’t get Gas Control, though maybe it is about the role trees play in CO2 regulation? I imagine the unsymmetrical T/I (in blue) was forced by the grid constraints—splitting MOISTURISING (and thus UNACHIEVABLE) would practically break the puzzle into two parts. I did notice that the grid was pangrammatic to boot!

In Chambers, looking up Christmas tree, the title will be revealed.

Unfortunately your drawing is not quite correct.

If you look next to the red M in each half of your grid then there is a symmetrical T, thereby ensuring a true symmetrical Christmas tree from the letters. The zigzagging also is more aesthetic.

Happy New Year to you all

Shark,

Thanks for the reply. I must have examined that grid a hundred times and yet I still failed to see, the now obvious, symmetrical placement of the Ts. I think I must have been drawn in by hat I felt was an aesthetic drawing. Many apologies for suggesting a failing in the grid construction where there was none, one reason I never send in my entries!

PS Really enjoyed the magpie puzzle and I think I may have got that one right.
