corresponding to the number of this letter, the letter of the secret text. Thus, suppose the first letter of the secret text to be A or B, and, likewise, the first letter of the words taken from without by the key to be C or D, the first of which occupies the third place in the alphabet, and the second the fourth place. Then the letter A or B of the secret text, following the count of the key, will take on the paper either the third or the fourth place in the line of points, according as the first letter of the key is C or D. And so we must continue till all the words of the epistle have been used up. Now, this being understood, our third care will be to make an accurate application of what has just been said. This will be done by first writing down the secret text, leaving between the rows, or lines, a space of sufficient width to allow us to write underneath these letter for letter, the key, and also above each letter of the key the number representing the place such letter holds in the alphabet. If the letters of the key do not correspond in number to the letters of the secret text, we must continue to repeat the letters of the key until the number of letters in each line is the same; thus,

When all that has been so far described has been done, turn to the line of points already made, and place, in the place belonging to the third point, the letter S, in the place belonging to the immediately following point the letter P, and in the space of the seventeenth point from this the letter I. That the letters may be written in the right order, two things have to be observed. First, when a letter, or character, has been set down, we must then, in reckoning the order of the letters, begin with the space immediately following this letter, which is the last written, and count forward to the last point of the line; then, continuing the count from this number, we must begin again with the spaces left empty at the head of the line; and so on. Secondly, the places of the points already occupied must be passed over without being counted. This statement is made clearer by the subjoined example, if one cares to follow, as here sufficiently directed, the process leading to the arrangement herein contained:
