This puzzle entailed the finding of an English word of three letters,
each letter being found on a different dial. Now, there is no English
word composed of consonants alone, and the only vowel appearing anywhere
on the dials is Y. No English word begins with Y and has the two other
letters consonants, and all the words of three letters ending in Y (with
two consonants) either begin with an S or have H, L, or R as their second
letter. But these four consonants do not appear. Therefore Y must occur
in the middle, and the only word that I can find is "PYX," and there can
be little doubt that this was the word. At any rate, it solves our
puzzle.
