Synopsis
A practical guide to sending and decoding coded telegrams with five-letter codewords.
This guide explains how to encode a message using Bentley's Second Phrase Code, and how to decode received codewords back into plain language. It covers the setup, the alphabet of codewords, and how to handle special cases like numerals and currency.
Learn the core workflow: locate the first phrase, write the matching five-letter codeword, and continue through the message to assemble a telegram. It also explains how to recognize and correct common decoding errors, and how to use the book’s tables and notes to manage numbers, dollars, and other currencies. The instructions emphasize clear, block-letter or typewritten telegams to avoid misreads.
The book stresses design features that reduce misreading and provide practical safeguards for telegraphic work, including how codewords are chosen to minimize ambiguity and how to handle mutilations during transmission. It also describes how the code is organized and how to apply optional numbered phrases when needed.
- Step-by-step encoding and decoding of five-letter codewords
- Guidance on handling numerals, currency, and special subjects
- Practical tips to avoid misreads and ensure accuracy
- How to use the code’s structure to adapt to individual needs

Paperback. Etat : New. Print on Demand. This book is a codebook that contains phrases and their corresponding five-letter codeword equivalents. An introduction explains how to use the codebook to encode and decode messages, including special instructions for encoding and decoding prices and currency. The five-letter codewords are arranged alphabetically, with each phrase placed under its subject word, that is, the most important word in the phrase. The codewords in this book have been carefully selected to have the following features: a minimum difference of two letters between any two codewords; if any two consecutive letters in any codeword are reversed, the word so formed will not be found in the code; and if any three consecutive letters in any codeword are reversed, the word so formed will not be found in the code. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. N° de réf. du vendeur 9780365775522_0
