Signal Stations

One of those topics that I can never find anything about when I need it (on web, too many photos, too many aimed at tourist sites, that sounds famiiar).

Mt Nelson Semaphore from State Library collection

Signals were sent from (Tasman Peninsula to) Mt Nelson to the signal station at Battery Point (doesn't seem possible these days, too many trees) e.g. notification of arriving ships

Three rows of arms. To represent a number, top row is digits, midde is tens, bottom is hundreds.

Each sets of arms can be in one of nine positions.



Can't remember the numbers which go with each postions, so for now I'll go

123
456
789

Using that, this would be 0 9 1. Then one looks up 91 in the book to see the corresponding message: Out of tea, send more.
