The sentence, “We meet to-night,” in this cipher would become, “Zh phhw wr-qljkw.”
The next is formed on the principle of the above, but is rather more intricate: for instance, if we wanted to inform some one that, “All going on well, send supplies as soon as possible,” we should put it down in the following order:—
| a | g | s | p | s | o |
| l | o | e | l | o | s |
| l | n | n | i | o | s |
| g | w | d | e | n | i |
| o | e | s | s | a | b |
| i | l | u | a | s | l |
| n | l | p | s | p | e |
You must read it down the first perpendicular column, then down the second, and so on. You must then form the letters in the horizontal columns into imaginary words, and place them down on paper as you would a common sentence, thus:—“Ag spso loelos lnn iosgwden ioes sab iluas lnlp spe.”
You must arrange with your correspondent beforehand that the width of the horizontal column should consist of six letters (or more, if you like); so by placing the letters six in a line, one under the other, without regard to words, the puzzle is easy to solve.
Another good cipher is by using the figures 1 and 2 differently arranged for every letter in the alphabet, as will be seen by the following key:—
| a | b | c | d | e | f | g | h | i |
| 11111 | 11112 | 11121 | 11122 | 11211 | 11212 | 11221 | 11222 | 12111 |
| j | k | l | m | n | o | p | q | r |
| 12112 | 12122 | 12211 | 12212 | 12221 | 12222 | 21111 | 21112 | 21121 |
| s | t | u | v | w | x | y | z | |
| 21122 | 21211 | 21212 | 21221 | 22222 | 22212 | 22221 | 22122 |
Now if we wanted to write the words “Come now,” we should do it in this way, knowing that there are five figures to every letter, and when a word is formed there is a comma:—
11121122221221211211, 122211222222222.
