Two rows of five horizontal cogwheels each are installed in a wall. Each cogwheel has five cogs protruding from the wall at any time. On each of these cogs is printed a single letter or a blank space. Thus, each row shows an adjustable line of text twenty-five characters long.
By spinning each of the cogwheels completely around, you have been able to determine what letters are on each of the cogs.
The first of the first row's cogwheels, for example, has sixteen cogs that show the characters:
["w", "h", "e", "n", " ", "d", "i", "s", "s", "o", "l", "v", "i", "n", "g", " "].
It can therefore be in sixteen possible positions, with sixteen different groups of five characters showing through its window, for example:
"when ", "en di", "lving", "g whe", etc.
Currently it is showing " diss".
Here are the characters that appear on all five of the first row's wheels:
["when dissolving ", "your being so that", " your stock of primetime ", "games is sufficiently", " hardy remember salt"].
(You see they have different numbers of cogs; but each displays only five at one time.)
The second row's wheels feature these characters:
["we nevertheless ", "want to let you know", " that down around ", "your neck of the woods", " is an unguarded grove"]
Currently, the cogwheels are in the following positions, and so seem to read:
" diss|ing s|our s|ames |ember" "less |want |round| the |grove"
" dissing sour sames ember" "less want round the grove"
Your task is to spin the wheels until they spell something intelligible!
(As it's not entirely impossible that what constitutes "intelligible" might be debatable, here is a hint that can also serve as a kind of checksum of your answer:
The correct couplet can be reached by a minimum total of 64 moves, or nudges, left or right, from the wheels' current positions.)
