“I now scrutinized the death’s-head with care. Its outer edges — the edges of the drawing nearest the edge of the vellum — were far more distinct than the others. It was clear that the action of the caloric had been imperfect or unequal. I immediately kindled a fire, and subjected every portion of the parchment to a glowing heat. At first, the only effect was the strengthening of the faint lines in the skull; but, on persevering in the experiment, there became visible, at the corner of the slip, diagonally opposite to the spot in which the death’s-head was delineated, the figure of what I at first supposed to be a goat. A closer scrutiny, however, satisfied me that it was intended for a kid.”
“Ha! ha!” said I, “to be sure I have no right to laugh at you — a million and a half of money is too serious a matter for mirth — but you are not about to establish a third link in your chain — you will not find any especial connexion between your pirates and goat — pirates, you know, have nothing to do with goats; they appertain to the farming interest.”
“But I have just said that the figure was not that of a goat.”
“Well, a kid then — pretty much the same thing.”
“Pretty much, but not altogether,” said Legrand. “You may have heard of one Captain Kidd. I at once looked on the figure of the animal as a kind of punning or hieroglyphical signature. I say signature; because its position on the vellum suggested this idea. The death’s-head at the corner diagonally opposite, had, in the same manner, the air of a stamp, or seal. But I was sorely put out by the absence of all else — of the body to my imagined instrument — of the text for my context.”
“I presume you expected to find a letter between the stamp and the signature.”
“Something of that kind. The fact is, I felt irresistibly impressed with a presentiment of some vast good fortune impending. I can scarcely say why. Perhaps, after all, it was rather a desire than an actual belief; — but do you know that Jupiter’s silly words, about the bug being of solid gold, had a remarkable effect on my fancy? And then the series of accidents and coincidences — these were so very extraordinary. Do you observe how mere an accident it was that these events should have occurred on the sole day of all the year in which it has been, or may be, sufficiently cool for fire, and that without the fire, or without the intervention of the dog at the precise moment in which he appeared, I should never have become aware of the death’s-head, and so never the possessor of the treasure?”
“But proceed — I am all impatience.”
“Well; you have heard, of course, the many stories current — the thousand vague rumors afloat about money buried, somewhere on the Atlantic coast, by Kidd and his associates. These rumors must have had some foundation in fact. And that the rumors have existed so long and so continuously could have resulted, it appeared to me, only from the circumstance of the buried treasure still remaining entombed. Had Kidd concealed his plunder for a time, and afterwards 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 is followers, who otherwise might never have heard that 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 downwards, 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. On taking it off, the whole was just as you see it now.”
Here Legrand, having re-heated 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;]
8*:+*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 on 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 on, 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 is removed by the signature. The pun on 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 case 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 |
