The transposed secret alphabet is not perfectly secure for private messages, when the message contains more than eight or ten words. It is, therefore, necessary to adopt some of the following modes of making it perfectly incomprehensible, and beyond the power of any person to decypher it. Any one or two, or more, of these modes may be selected and combined for this purpose. Let the following key or transposed alphabet, be used in illustrating the following rules: A to R | F to X | K to U | P to E | U to K | Z to M B Y | G B | L V | Q P | V G | & I C Z | H T | M D | R L | W N | D A | I W | N & | S F | X J | E S | J C | O Q | T O | Y H | 1st. Let the last letter of a word remain unchanged, viz. _Rome_, transposed, _lqde_. 2d. Let the first letter of a word remain unchanged, viz. _Rome_, transposed, _rqds_. 3d. Let the first and last letter remain unchanged, viz. _Rome_, transposed, _rqde_. 4th. Let the middle letter of a word of 5, 7, 9 or 11 letters remain unchanged, viz. _First_, transposed, _xwrfo_, and in words of 4, 6, 8, 10 or 12 letters, let the two middle letters remain unchanged, viz. _Rome_, transposed, _loms_. 5th. Let the first, middle, and last letters of a word remain unchanged, viz. _first_, transposed, _fwrft_. 6th. Let the middle letter of words of 5, 7, 9, 11 or 13 letters commence the word, viz. _first_, transposed, _lxwfo_. 7th. Let the two middle letters of a word of 4, 6, 8, 10 or 12 letters commence the word, viz. _Rome_ transposed, _qdls_. 8th. In a word of 4, 6, 8, 10, 12 or 14 letters, let the first half of the word be substituted for the last half, viz. _Rome_, transposed, _dslq_. 9th. Let every other entire word be reversed, viz. _What is the news_, transposed, _ntro fw ots fns_ &. 10th. Let every third word be reversed. 11th. Let every fourth word be reversed. 12th. Let every fifth word be reversed. 13th. Let the three middle letters of every word of 5, 7, 9, 11 or 13 letters be reversed, viz. _first_, transposed, _xflwo_. 14th. Let every word of two or three letters be prefixed to the beginning of the following word, or affixed to the end of the preceding word, viz, _State of Maine_, transposed, _forosqx drw&s_. 15th. Let one, where double letters occur in a word, be excluded, viz. _will_ transposed, _nwv_. 16th. Where two or more words, of two or three letters, follow each other, let them be joined together, viz. _Cotton is on the rise_, transposed, _zqoq& wfq&ots lwfs_. 17th. Make no separation between words of less than eight letters, viz. _Cotton is on the rise_, transposed, _zqoq&wfq&otslwfs_. 18th. Make no separation between words.
