In The Shadow Of The Master: Classic Tales by Edgar Allan Poe

Kidd concealed his plunder for a time, and afterward reclaimed it, the rumors would scarcely have reached us in their present unvarying form. You will observe that the stories told are all about money-seekers, not about money-finders. Had the pirate recovered his money, there the affair would have dropped. It seemed to me that some accident-say the loss of a memorandum indicating its locality-had deprived him of the means of recovering it, and that this accident had become known to his followers, who otherwise might never have heard that the treasure had been concealed at all, and who, busying themselves in vain, because unguided, attempts to regain it, had given first birth, and then universal currency, to the reports which are now so common. Have you ever heard of any important treasure being unearthed along the coast?”

“Never.”

“But that Kidd’s accumulations were immense, is well known. I took it for granted, therefore, that the earth still held them; and you will scarcely be surprised when I tell you that I felt a hope, nearly amounting to certainty, that the parchment so strangely found involved a lost record of the place of deposit.”

“But how did you proceed?”

“I held the vellum again to the fire, after increasing the heat, but nothing appeared. I now thought it possible that the coating of dirt might have something to do with the failure: so I carefully rinsed the parchment by pouring warm water over it, and, having done this, I placed it in a tin pan, with the skull downward, and put the pan upon a furnace of lighted charcoal. In a few minutes, the pan having become thoroughly heated, I removed the slip, and, to my inexpressible joy, found it spotted, in several places, with what appeared to be figures arranged in lines. Again I placed it in the pan, and suffered it to remain another minute. Upon taking it off, the whole was just as you see it now.”

Here Legrand, having reheated the parchment, submitted it to my inspection. The following characters were rudely traced, in a red tint, between the death’s-head and the goat:

“53‡‡†305))6*;4826)4‡.)4‡);806*;48†8¶60))85;1‡(;:‡*8†83(88)5*†;46(;88*96*?;8)*‡ (;485);5*†2:*‡ (;4956*2 (5*-4)8¶8*;4069285);)6†8)4‡‡;1 (‡9;48081;8:8‡1;48†85;4) 485† 528806*81 (‡9;48;(88;4(‡?34;48) 4‡;161;:188;‡?;”

“But,” said I, returning him the slip, “I am as much in the dark as ever. Were all the jewels of Golconda awaiting me upon my solution of this enigma, I am quite sure that I should be unable to earn them.”

“And yet,” said Legrand, “the solution is by no means so difficult as you might be led to imagine from the first hasty inspection of the characters. These characters, as any one might readily guess, form a cipher-that is to say, they convey a meaning; but then from what is known of Kidd, I could not suppose him capable of constructing any of the more abstruse cryptographs. I made up my mind, at once, that this was of a simple species-such, however, as would appear, to the crude intellect of the sailor, absolutely insoluble without the key.”

“And you really solved it?”

“Readily; I have solved others of an abstruseness ten thousand times greater. Circumstances, and a certain bias of mind, have led me to take interest in such riddles, and it may well be doubted whether human ingenuity can construct an enigma of the kind which human ingenuity may not, by proper application, resolve. In fact, having once established connected and legible characters, I scarcely gave a thought to the mere difficulty of developing their import.

“In the present case-indeed in all cases of secret writing-the first question regards the language of the cipher; for the principles of solution, so far, especially, as the more simple ciphers are concerned, depend upon, and are varied by, the genius of the particular idiom. In general, there is no alternative but experiment (directed by probabilities) of every tongue known to him who attempts the solution, until the true one be attained. But, with the cipher now before us all difficulty was removed by the signature. The pun upon the word ‘Kidd’ is appreciable in no other language than the English. But for this consideration I should have begun my attempts with the Spanish and French, as the tongues in which a secret of this kind would most naturally have been written by a pirate of the Spanish Main. As it was, I assumed the cryptograph to be English.

“You observe there are no divisions between the words. Had there been divisions the task would have been comparatively easy. In such cases I should have commenced with a collation and analysis of the shorter words, and, had a word of a single letter occurred, as is most likely, (a or I, for example), I should have considered the solution as assured. But, there being no division, my first step was to ascertain the predominant letters, as well as the least frequent. Counting all, I constructed a table thus:

Of the character 8 there are 33.

; “ 26.

4 “ 19.

‡) “ 16.

* “ 13.

5 “ 12.

6 “ 11.

† 1 “ 8.

0 “ 6.

Of the character 92 there are 5.

:3 “ 4.

? “ 3.

¶ “ 2.

– . “ 1.

“Now, in English, the letter which most frequently occurs is e. Afterward, the succession runs thus: aoidhnrstuycfglmwbkpqxz. E predominates so remarkably, that an individual sentence of any length is rarely seen, in which it is not the prevailing character.

“Here, then, we have, in the very beginning, the groundwork for something more than a mere guess. The general use which may be made of the table is obvious-but, in this particular cipher, we shall only very partially require its aid. As our predominant character is 8, we will commence by assuming it as the e of the natural alphabet. To verify the supposition, let us observe if the 8 be seen often in couples-for e is doubled with great frequency in English-in such words, for example, as ‘meet,’ ‘fleet,’ ‘speed,’ ‘seen,’ ‘been,’ ‘agree,’ etc. In the present instance we see it doubled no less than five times, although the cryptograph is brief. Let us assume 8, then, as e. Now, of all words in the language, ‘the’ is most usual; let us see, therefore, whether there are not repetitions of any three characters, in the same order of collocation, the last of them being 8. If we discover repetitions of such letters, so arranged, they will most probably represent the word ‘the.’ Upon inspection, we find no less than seven such arrangements, the characters being;48. We may, therefore, assume that; represents t, 4 represents h, and 8 represents e-the last being now well confirmed. Thus a great step has been taken.

“But, having established a single word, we are enabled to establish a vastly important point; that is to say, several commencements and terminations of other words. Let us refer, for example, to the last instance but one, in which the combination;48 occurs-not far from the end of the cipher. We know that the; immediately ensuing is the commencement of a word, and, of the six characters succeeding this ‘the,’ we are cognizant of no less than five. Let us set these characters down, thus, by the letters we know them to represent, leaving a space for the unknown-

t eeth

“Here we are enabled, at once, to discard the ‘ th,’ as forming no portion of the word commencing with the first t; since, by experiment of the entire alphabet for a letter adapted to the vacancy, we perceive that no word can be formed of which this th can be a part. We are thus narrowed into
