Post Number 49
Codes
Hello Everyone
Last week Bill and Bob were learning about flags at school and l told them how flags could be used to send messages. This week by coincidence they started learning about signals and codes at Beaver Scouts.
They learnt about semaphore, which is sending messages across a distance using two flags held in different positions. Each position represents a letter of the alphabet.
Bill and Bob thought that it was all too difficult to remember it all. They concluded that it was much easier to use a mobile ’phone. 
When they set up camp in Auntie Alice’s garden they use their walky-talky set. One set in their tent and one in the kitchen which enables Auntie Alice to tell them when their tea is ready.
When they play at being secret agents, because they are twins, each calls himself Agent 003½.
They then decided that they would make up their own secret code so that they could send each other secret messages that no one else could understand.
Here it is…
Each symbol represents a letter of the alphabet.
A ! J < S ∆
B # K > T ∏
C & L ? U ∑
D ( M [ V √
E ) N ] W ∞
F * O ÷ X ∫
G + P † Y ≠
H 0 Q ‡ Z ◊
I : R •
Can you work out what these Bill and Bob secret messages say?

Signal–flag training set used by sailors to help them learn signal codes
The little flags are made of wood
The pattern and colours on each flag represents a number or letter and so spell out words when arranged in groups
Signal flags were hoisted high up in the rigging of a ship so that using a telescope
the signal flags could be seen by other ships from miles away
A model of a shutter telegraph model (about 1795)
This way of sending coded messages was used to communicate between London and the coast from 1796 – a chain of huts was built on high ground and messages were sent from one hut to another down the chain by positioning the shutters in a certain way
It needed four men in each hut to keep watch with telescopes and operate the shutters using ropes – although the messages could travel so much more quickly than a messenger on a horse, the system did not work in fog or heavy rain
A ship’s telegraph was used to communicate between the bridge where the captain stood and looked out to sea and the engine room – the handles on this machine would be moved and a bell would sound signals for the crew in the engine room
The captain would give orders regarding speed and direction and the engine room would signal back that they had carried out the order – you may have seen these in old movies
Today ships usually use internal telephones
The electric telegraph revolutionized communication over long distances and lead to the development of Morse code in 1837
Morse code messages could be sent from ships using flashing lights – this hand held light from the 1950s had a trigger in order to switch the light on and off quickly so that the dots and dashes could be signalled between ships or across land
Morse Code – This was invented by Morse’s colleague Alfred Vail
It is actually a cipher not a code because letters are represented rather than words
A machine for sending Morse Code messages
Messages can be sent in Morse code using pulses of electricity and there are still people today
who use it to communicate with each other as a hobby
The children’s activity centre at the National Maritime Museum
where you can have a go at sending your own Morse Code messages
The first mobile telephones were much larger than they are today
They were almost the size of a house brick
Some messages can be conveyed in pictures – this lion represents England and the unicorn represents Scotland
Of course you already know these and you will know what they mean in any country even if you can’t speak the language there
Flags represent countries or sometimes organizations
Flags can be seen at a distance

Of course when you create codes, it is really important to get your spelling right otherwise your message could be confused and difficult to understand.
Sometimes there are typos in the Rocky Bay Gazette, our local newspaper, which make us smile. Here are some of the most memorable ones.

HOW TO MAKE lNVlSlBLE lNK
Another way to send secret messages is by using invisible ink!
METHOD ONE
Write your message with a cotton bud or tooth pick using slightly diluted lemon juice or milk. In order for your message to be read, the person receiving it just has to heat the piece of paper up next to a light bulb.
*(Be careful – light bulbs get hotter than you think!)
METHOD TWO
Write your message in white crayon and expose it by just rubbing another colour crayon over it!
