Francis Bacon used his two-typeface system to embed the message into another text or “carrier text”.It takes five letters in the carrier text to get one letter of the hidden text.If you wanted to communicate the word “micro” (5 letters) in code, you would need to have a carrier text of 25 letters (5 times 5). Example: How much wood cOUld a woodchuck cHuck if a woodchuck couLd chuck wood? He CoulDcHUCk as much wood as a woodchuck could chuck.
