Introduction

Would you like to send your best friend a message without anyone else knowing what it says? If you think it would be fun, then close the door, pull down the shades, and discover the secret world of codes!

Codes have lots of different uses. You can use them to pass notes in school or write down your innermost feelings in a diary. They all are kept perfectly safe from a nosy little brother or a tattletale big sister.

If you and your friends have a club, codes are a neat way to exchange messages and passwords. They are sure to outfox even the brainiest spy.

You will learn how to make a real code machine. A version of it actually was used during the American Civil War (1861—1865). You can use it to send secret messages.

Coded writing has been used for thousands of years. Generals planning surprise attacks used it. Spies, secret agents, and smugglers all used it. Famous people used it. Even Franklin Delano Roosevelt, before he became president, wrote his secret diaries in code.

Most of the time when people talk about codes they really mean ciphers. Ciphers are a special kind of secret writing in which the words and letters have been shuffled, twisted, or disguised in all sorts of ways. In this book, the word code is used to mean cipher.

Before you turn the page, here is a word of warning. Be sure to hide this code book in a very safe place. Only you and your special friends should know its secrets. After all, you wouldn’t want a curious spy snoop to discover it!

Are you ready? Then turn the page and begin. I happy coding!
