upon the subject, in which I analyze one hundred and sixty separate ciphers; but I confess that this is entirely new to me. The object of those who invented the system has apparently been to conceal that these characters convey a message, and to give the idea that they are the mere random sketches of children.

"Having once recognised, however, that the symbols stood for letters, and having applied the rules which guide us in all forms of secret writings, the solution was easy enough. The first message submitted to me was so short that it was impossible for me to do more than to say with some confidence that the symbol

stood for E. As you are aware, E is the most common letter in the English alphabet, and it predominates to so marked an extent that even in a short sentence one would expect to find it most often. Out of fifteen symbols in the first message four were the same, so it was reasonable to set this down as E. It is true that in some cases the figure was bearing a flag and in some cases not, but it was probable from the way in which the flags were distributed that they were used to break the sentence up into words. I accepted this as a hypothesis, and noted that E was represented by

"But now came the rear difficulty of the inquiry. The order of the English letters after E is by no means well marked, and any preponderance which may be shown in an average of a printed sheet may be reversed. in a single short sentence. Speaking roughly, T, A, O, I, N, S, H, R, D, and L are the numerical order in which letters occur; but T, A, O, and I are very nearly abreast of each other, and it would be an endless task to try each combination until a meaning was arrived at. I, therefore, waited for fresh material. In my second interview with Mr. Hilton Cubitt he was able to give me two other short sentences and one message, which appeared—since there was no flag—to be a single word. Here are the symbols. Now, in the single word I have already got the two E's coming second and fourth in a word of five letters. It might be 'sever,' or 'lever,' or 'never.' There can be no question that the latter as a reply to an appeal is far the most probable, and the circumstances pointed to its being a reply written by the lady. Accepting it as correct, we are now able to say that the symbols

stand respectively for N, V, and R.

"Even now I was in considerable difficulty, but a happy thought put me in possession of several other letters. It occurred to me that if these appeals came, as I expected, from someone who had been intimate with the lady in her early life, a combination which contained two E's with three letters between might very well stand for the name 'ELSIE.' On examination I found that such a combination formed the termination of the message which was three times repeated. It was certainly some appeal to 'Elsie.' In this way I had got my L, S, and I. But what appeal could it be? There were only four letters in the word which preceded 'Elsie,' and it ended in E. Surely the word must be 'COME.' I tried all other four letters ending in E, but could find none to fit the case. So now I was in possession of C, O, and M, and I was in a position to attack the first message once more, dividing it into words and putting dots for each symbol which was still unknown. So treated it worked out in this fashion:—

"Now the first letter can only be A, which is a most useful discovery, since it occurs no fewer than three times in this short sentence, and the H is also apparent in the second word. Now it becomes:—

Or, filling in the obvious vacancies in the name:—

I had so many letters now that I could proceed with considerable confidence to the second message, which worked out in this fashion:—

Here I could only make sense by putting T and G for the missing letters, and supposing that the name was that of some house or inn at which the writer was staying."

Inspector Martin and I had listened with the utmost interest to the full and clear account of how my friend had produced results which had led to so complete a command over our difficulties.

"What did you do then, sir?" asked the inspector.

"I had every reason to suppose that this Abe Slaney was an American, since Abe is
