it, and were engaged in its examination. When I considered all these particulars, I doubted not for a moment that heat had been the agent in bringing to light, upon the parchment, the skull which I saw designed upon it. You are well aware that chemical preparations exist, and have existed time out of mind, by means of which it is possible to write upon either paper or vellum, so that the characters shall become visible only when subjected to the action of fire. Zaffre, digested in aqua regia, and diluted with four times its weight of water, is sometimes employed; a green tint results. The regulus of cobalt, dissolved in spirit of nitre, gives a red. These colours disappear at longer or shorter intervals after the material written upon cools, but again become apparent upon the reapplication of heat.
‘I now scrutinised 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, upon 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 special connection between your pirates and a 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 upon the figure of the animal as a kind of punning or hieroglyphical signature. I say signature; because its position upon 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 upon 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 upon 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 rumours afloat, about money buried, somewhere upon the Atlantic coast, by Kidd and his associates. These rumours must have had some foundation in fact. And that the rumours have existed so long and so continuous, 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 rumours 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 treasure had been concealed at all, and who, busying themselves
