Continuing the theme of codes..
Properly Practised, knitting soothes the troubled spirit, and doesn`t hurt the
untroubled spirit,either. By Elizabeth Zimmerman

REAL KNITTING
The word knitting comes from the Old English cnyttan,meaning `to knot`.
What we now call knitting-making a textile by looping yarn using two needles-
isn`t much older than 1.000 years and it wasn`t until the Renaissance that
wool was used rather than silk or cotton.
The verb `to knit` isn`t recorded in English unti 1400.
The earliest fragments of apparently knitted material were excavated at the
fort of Dura-Europos in Syria in 1935 and date from 265AD, there are also socks
from Coptic Egypt dating to the 4th century AD, but all these are made using
a technique known as `nalebinding` which only uses one needle.

KNITTING CODES
During the Second World War the Office of Censorship banned people from
posting knitting patterns abroad in case they contained coded messaages.
There was many occasions when knitting was used for code.
The Belgian resistance recruited old women whose windows overlooked
railway yards to note the trains in their knitting,basically the women would
purl a stich if a artillery train went by and drop a stitch for troop train.

The most favourite example of knitting being used to record information
is Madame Defarge in Dicken`s A Tale Of Two Cities,she sits by the
guillotine as the enemies of the French Revolution are beheaded, calmly
recording their names n wool as their heads fall into the basket,although
there is no evidence tricoteuses-knitting women, exsisted in that time
of history.

MORSE CODE
Morse code messages could also be sent in a morse code form by
knitting it into a simple gament like a scarf, knitting a purl stitch for
`a dot`and a knit stitch for `dash`
During the war some coutries instituted what might on the surface
appear to be a series of seemingly bizarre resstrictions, the following
were among banned items: the international mailing of postal chess
games,crossword puzzles.newspaper clipping and knitted instuctions,
lovers `X`s and `O`s, etc all of which could serve as a communication
for spies.

Good evening Hope, major thanks as ever for your tireless and intriguing contributions.

Ah Mr Morse ..... an exceedingly clever chap, but he wasn't the person that physically devised the code I've since discovered, it was this very post that drew me into the web along with insatiable curiosity of course!

Another version of what was known in Europe as the electrical telegraph was independently developed and patented in the United States in 1837, by Samuel Morse. However it was his assistant, Alfred Vail, who developed the Morse code signalling alphabet as Morse's subordinate. The first telegram in America was sent by Morse on 11 January 1838, across a two mile (3 kilometres) stretch of wire at Speedwell Ironworks near Morristown, New Jersey. Only later, in 1844, did he send the message WHAT HATH GOD WROUGHT from the Capitol in Washington to the old Mt. Clare Depot in Baltimore. The Morse/Vail telegraph was rapidly deployed over the following two decades. By 24th October 1861 the overland telegraph had been extended to connect the west coast of the North American continent to the east coast, effectively bringing the reign of the Pony Express (messages carried by a relay of riders) to an end.

Meanwhile in Britain, Edward Davy successfully demonstrated his telegraph system in Regent's Park in 1837 and as a result was granted a patent on 4 July 1838. He also developed an electric relay.

It was David Edward Hughes who made a major step forward with the invention of the printing telegraph in 1855. The device used a keyboard of 26 keys for the alphabet and a spinning type wheel that determined the letter being transmitted according to the length of time that had elapsed since the previous transmission. The system also facilitated automatic recording on the receiving end. Hughes' invention proved to be a highly stable and accurate system which became accepted around the world.

The next improvement was the Baudot code of 1874. Designed by French engineer Emile Baudot who patented a printing telegraph through which signals were translated automatically into typographic characters. Each character was assigned a unique code based on the sequence of of a mere five contacts. Operators had to maintain a steady rhythm, and the customary transmission speed was 30 words per minute.
