Might have been an off-brand.

The girl that is sitting in a circle in Riverville by Gatzitormatalata's house gave me a little hint that in Tannerman's house there are some switches that supposedly reveal something good (you have to pay her 30 pennies for the hint). Anyway, The switch nearest the door on the side of the bookcase will not switch for anything. Is this a glitch? (I know about the other two: one on the side of the fireplace and the other up high by the elk head).

I've been reading "Going Postal" by Terry Pratchett and it heavily involves the "clacks" which is Semaphore technology. I know it was used somewhat during the Napoleonic wars, but I can't find any good sources that go in depth on it.
