Samuel Finley Breese Morse was a talented artist and teacher who became famous for an invention that sprang from a hobby. He invented the telegraph. Morse financed his innovation by painting and teaching art at New York University. Despite the discouraging comments of his fellow professors, Morse toiled at the telegraph until it was perfected. The next problem was to create a vocabulary for his invention—a special language without words.
Morse's idea was to have an alphabet made entirely of symbols which could be sent over a telegraph wire, thereby hastening the transmission of messages. He came up with a system of dots (小點) and dashes (破折號) which could be “tapped” on the telegraph, arranged in combinations to represent every letter in the alphabet.
The United States Congress became curious about this invention and invited Morse to Capitol Hill for a demonstration of his telegraph on May 24, 1844. Morse demonstrated his skills by sending a message from Washington, D. C. , to Baltimore. That message was successfully transmitted and received, and a new era in communications technology was born.
Today, the Morse Code (摩爾斯碼) is so widely used that it is no longer considered a secret language. One advantage to the code, despite its seeming mystery, is that a variety of “telegraph” instruments may be used—finger tapping buzzers (蜂間器), whistles (口笛), lights, and even flags.
Flag transmission is relatively simple to perform, but it requires special equipment. In areas with dark backgrounds, a white flag which a small square of red in the center is preferred. Conversely, in areas featuring a light background, a dark colored flag with a small square of white in the center is most efficient.
The flag code involves three movements, all of which be-gin and end with the flag being held perpendicular (成直角的) in front of the sender. A dot is created by swinging the flag down to the right and back in position; a dash is made by swinging the flag down to the left and back. An interval (間歇) is created by waving the flag down in front and back in position. There are no pauses between dots and dashes, but pauses are used to indicate the end of a letter. One interval indicates the end of a word, two signify the end of a sentence, and three intervals indicate the message's end.
Morse Code is thus remarkable not only for its efficiency, but also for its versatility and relative ease of use.

Eddie was in the back of the shop counting the day's takings when the doorbell rang. It was just on closing time and shutters were already up in front. Normally there were few customers after five, and the half hour before he shut the shop was mainly devoted to getting orders ready for the morning and entering up the accounts. Of course it might be Maureen, who had lately developed a habit of coming into the shop just before closing time and so making sure that Eddie did not escape her for the evening.
With a sigh Eddie put down his pen and came out from the back and went behind the counter. As he did so, he was fuming over in his mind what possible excuse he could offer to Maureen for not spending the evening with her. If only Maureen would accept the excuse of a headache or pressure of work. But she would want to stay and fuss over him if he said a headache, and as for work, she was always bothering him to move into a district where there was more business than in Candlewick Street. “Why is it, ”thought Eddie, “that she can't leave me alone for one evening? Doesn't it ever occur to her that I'd like a bit of time to myself?”
There was a woman in the shop and a man standing with his back half turned towards the counter. The woman was not Maureen, he didn't recollect ever having seen her before, but there was something vaguely familiar about the way the man was standing. It reminded him of the bare white-washed walls of St. Matthews hospital and Sam Lewis standing with his back towards Eddie staring out of the window.
The man turned. “Well, Eddie, ”he said, “it seems we've caught you just before lock-up time, eh?”
