A bout 170 years ago, no one knew how to transmit voices (or music) over the radio. (Heck, no one even knew that radio waves existed. ) It was impossible to communicate quickly with someone who lived thousands of miles away. (Remember—no e-mail, no faxes, no text messaging, no telephones … egads!) Fortunately, a man named Samuel Morse (1791–1872) developed a code, called Morse code , which enabled people to communicate quickly over long distances. This communication system was called the telegraph .

    Morse code doesn’t require the human voice or even a piece of paper. Instead, it uses a pattern of short and long beeps called dots and dashes . Each letter is assigned its own pattern of dots and dashes. For instance, the letter K is composed of a dash, a dot, and a dash. It is written as follows: –.–, and it sounds like “beeeep, beep, beeeep.” A trained listener would know that he or she was hearing the letter K.
    When Nell sent Drake a secret message, she wrote it in Morse code. You, too, can write messages in Morse code. Use / to indicate the end of a letter, // for the end of a word, and /// for the end of a sentence. Practice your detective skills by decoding the following:

    If you have access to the Internet, you can actually hear what Morse code sounds like. Go to http://morsecode.scphillips.com/translator.html , and type a message in the “input text” box. Click “Play Sound,” and then click “Submit.” Pretty nifty, eh? Another Web site that allows you to hear Morse code is http://www.battleshipnc.com/kids/games/morse/translator.php.
    You can also practice your skills using the online Morse code machine at www.boyslife.org/games/online-games/575/morse-code-machine.
