Birmingham Alabama has a large statue on top of a mountain that is " Vulcan, the God of Iron and Steal " . Vulcan holds in his hand, high above his head, a light that is visible from almost everywhere in Birmingham. The light is used to send a message to all of those who can see it. The light remains green if nobody has been killed in a vehicle accident in Birmingham, and if someone has been killed that day in a vehicle accident, the light turns red. I was always fascinated by this message that was being transmitted to so many people, in an attempt to make people more aware of the dangers of driving wrecklessly, or by becoming distracted. Even in this day of mass communication, The statue of Vulcan is sending a message 24 hours a day, every day of the year, reminding people to slow down and be careful, and try to keep the light green. Or if is red, to remember that traffic had already claimed at least one life on this day. Such a simple signal, designed to curve everyone's behavior and awareness of all those who can see it.

Good one, as usual THG, however it leaves me slightly puzzled. I am fairly certain the Royal Navy had a chain of signal towers between central London, down what is now the A3 to Portsmouth Dockyard. (I know you know the route and the dockyard) Messages could be passed from the Admiralty to the Royal Dockyard in (I think) minutes and certainly an hour or so. I think it was a semaphore based system, since the RN were adept at various forms of signaling. Nelson himself was a well known and prolific originator or signals. Apropos of which, most of the world knows of Nelson's historic signal before the battle of Trafalgar, but fewer know of a couple of interesting cameos connected with it. The old pub quiz classic is; 'What signal was flown during the battle of Trafalgar?' Not "England expects....." but #16 'Engage the enemy more closely.' When Nelson dictated the signal he wanted to make to the fleet, his Flag Lieutenant (Lt Pascoe) said; "My Lord, if I may suggest 'expects' rather than 'confides' (which Nelson had used) which has a flag, else I shall have to spell confides."? Nelson agreed and the signal was 'bent on'. Although his famous signal probably did have an encouraging effect on the fleet, they sorely needed it, because the two divisions (one led by Adm Cuthbert Colinwood, the other by Nelson himself) had been under fire for about four hours. This was a trying time, because neither Nelson nor Colinwood could bring guns to bear to much effect. When Nelson's signal finally rippled through the fleet, Colinwood was heard to mutter rather testily; "I do wish that man would stop signaling!"

I recall a 'Telegraph Hill' near Hinchley Wood in Surrey, presumably one of the towers of this route between Portsmouth and London was built there but no longer exists. They used a system of 'Murray Shutters' (see wiki) installed in March 1796. According to the National Museum of the Royal Navy, 'the system linked the Admiralty building in London and Portsmouth through telegraph stations, including Putney, Chessington, Haslemere, Bedhampton, and ended next to the King’s Bastion, Portsmouth. Workers at the stations would watch through telescopes and take down the message, then pass it on by pulling ropes attached to the back of the shutters to spell it out'. 'This line could send important messages from the Royal Naval base in Portsmouth to London in 7.5 minutes, far quicker than any other method of communication at the time. The next fastest method was to carry a message by horse, which would take at least 4.5 hours. One telegraph station’s journal even notes that a message was sent from London to Portsmouth in one minute'. It was operating well enough into the 1840s and was a reason given for not building an electrical telegraph on this route early on.

Interestingly the RN still used semaphore, morse and flags by preference into world war 1, which was one of the reasons the High Seas Fleet wasn't aware that the Grand Fleet was at sea at Jutland, whereas the HSF made pridigous use of their radios. Infact the British Signals intelligence had tracked the HSF out to sea however the RN liason to them was apparently not well liked and when he asked him where DZ had last signalled from (the code associated with Derflinger, they responded in port, as that was the code she used in port as opposed to another code she used at sea) after Jellicoe encountered her at sea he then discounted all the messages as unreliable telling him that the route the HSF was taking home and so missed the chance to intercept (and probably destroy) the German Navy.

@@tomriley5790 The error there was that a specific question was asked, and the technically correct answer was given, rather than the information actually desired. The problem was Jelicoe hadn't asked the question he actually wanted the answer too, which was where was Derflinger. SigIntel KNEW Derflinger was at sea, but Jelicoe hadn't asked where she was, despite wanting to know that. In the end, of course, it was merciful that Jelicoe didn't destroy the German navy. They never put to sea again for a fight. (There was a try, but the sailors weren't having any of the 'glorious last stand' rubbish when they just had to sit around for a bit longer and the war would be over without any meaningful change in the outcome.)

And this is why Samuel Morse's device is always referred to in contemporary accounts as the Electric Telegraph, since the Optical Telegraph was already well known at the time. While the details are not well known, the existence of this system is well known among fans o the late Terry Pratchet's Discworld series. During the series, an optical telegraph system officially known as the Grand Trunk and unofficially known as The Clacks is built (and one novel in the series, Going Postal, is about how the newly revitalized post office brings down a criminal conspiracy to steal it from it's proper owners). This mechanics of the system is quite different (it's a digital binary system, based on an unspecified sized array of sliding shutters, which are black or white for daytime use and block or show oil lamps for night time use) but like the French system the operator just replicates the pattern seen on the upstream tower without any knowledge of the content of the stream of data (except that non-encoded messages are readable by skilled operators). It is possible to send messages to tower operators, which automatically get printed out at the destination tower and automatically deleted from the stream afterwards, just like messages sent to specific places are automatically filtered out of other message streams by the mechanisms, which the French system would not likely have been able to do. Like the French system, there's a portable version used by the military that shows up in another, later novel, Monstrous Regiment (which is itself a historical reference). Operationally, it's sort of a cross between an optical telegraph and short-wave radio, down to the code used as a general response request being 'CQ'.

There is contemporary to that time a song that is a 3 way love story about a ship to shore com being intercepted. Facebook by flags. What's new? Morse's assistant Vail had the idea to make serial lookup table code to string a series of a single bit instead of a set of bits. One wire or fire instead of several. We call it Morse Code but give credit where it's due. In both world wars the ability to send Morse by what ever way might work was basic req.

Hello graphs were another system of long distance communication not involving wires. It was commonly used by various militaries as it was portable and easily set up.

While that very long time to send a message might seem quaint now a days, it turns out that some nations, Russia, China, and India, submarines use a system that is just as slow. They use Extremely Low Frequency (ELF) to transmit messages to submarines at operational depths. The submarine trails a very long wire behind it to receive the low frequency signals. Because the signals are so slow, messages are very brief, and encoded. Essentially to say something like "Come near the surface. We want to talk." The United States used to have a similar system in Wisconsin and Michigan, but for political reasons it was shut down.

I'm having problems picturing submarines in use in those midwest U.S. states. ;-) I suppose they were cruising in the Great Lakes.
