Part 5 of Ralph Griswold's Code Drafting series, on message drafting: embedding a text in an overshot weave so the message can be recovered. Earlier methods could not be reversed because different strings gave the same sequence, so he assigns each letter a unique six-term sequence of alternating parity for four shafts. He gives a randomly chosen 26-letter code table and works out the sequence for the word TRANQUILITY. A drawdown of the resulting weave is on the last page, and the text notes limits and the cryptographic aspect.
