Chapter III

On Arbitrary Simple Transposition

We come now to the second kind of Transposition: namely, Arbitrary Transposition (for this is opposed to what I have called Natural Transposition).  Arbitrary Transposition takes place when, paying little or no regard to the natural order in which the letters occur in the alphabet, we make the substitution of a letter for letter with all freedom, according to the following or any other Mode:

A b c d e f g h i k l m n o p q r s t u x y z
h r g s x a m c l p n b z q f e k u y t i d o

There is little chance, however, that this simple method will escape the observation of the clever and diligent searcher.  No less is true of that other method which, by means of a middle alphabet, lying between two other alphabets, advances by continued Transposition of the letters of both of these latter, -- a method I have touched upon below, in the beginning of my Sixth Mode, Bk. 9.c.5.  this being the case, I have here provided another method, in which the Order of Letters is observed, but the order of the alphabets, as it was presented in the table of the preceding chapter, is found to be broken: thus,

A B C D E F G H I K L M N O P Q R S T V X Y Z

o p q r s t v x y z a b c d e f g h i k l m n
p q r s t v x y z a b c d e f g h i k l m n o

If, however, you think even this method of writing unsafe, there may be constructed another table, wherein the letters are written quite without order.  A specimen thereof is presented in this that follows:
