fast asleep, I betook myself to a more methodical investigation of the affair. In the first place I considered the manner in which the parchment had come into my possession. The spot where we discovered the scarabæus was on the coast of the main land, about a mile

eastward of the island, and but a short distance above high-water mark. Upon my taking hold of it, it gave me a sharp bite, which caused me to let it drop. Jupiter, with his accustomed caution, before seizing the insect,

which had flown towards him, looked about him for a leaf, or something of that nature, by which to take hold of it. It was at this moment that his eyes, and mine also, fell upon the scrap of parchment, which I then supposed to be paper. It was lying half buried in the sand, a corner sticking up. Near the spot where we found it, I observed the remnant of the hull of what appeared to have been a ship's long boat. The wreck seemed to have been there for a very great while; for the resemblance to boat timbers could scarcely be traced.

"Well, Jupiter picked up the parchment, wrapped the beetle in it, and gave it to me. Soon afterwards we turned to go home, and on the way met Lieutenant G- I showed him

the insect, and he begged me to let him take it to the fort. Upon my consenting, he thrust it forthwith into his waistcoat pocket, without the parchment in which it had been wrapped, and which I had continued to hold in my hand during his inspection. Perhaps he dreaded my changing my mind, and thought it best to make sure of the prize at once-you know how enthusiastic he is on all subjects connected with Natural History. At the same time, without being conscious of it, I must have deposited the parchment in my own pocket.

You remember that when I went to the table, for the purpose of making a sketch of the beetle, I found no paper where it was usually kept. I looked in the drawer, and found none

there. I searched my pockets, hoping to find an old letter, when my hand fell upon the parchment. I thus detail the precise mode in which it came into my possession; for the circumstances impressed me with peculiar force.

No doubt you will think me fanciful-but I had already established a kind of connection. I had put together two links of a great chain. There was a boat lying upon a sea-coast, and not far from the boat was a parchment-not a paper-with a skull depicted upon it. You will, of course, ask 'where is the connection?' I reply that the skull or death's-head is the well-known emblem of the pirate. The flag of the death's-head is hoisted in all engagements.

“I have said that the scrap was parchment, and not paper. Parchment is durable-almost imperishable. Matters of little moment are rarely consigned to parchment; since for the mere ordinary purposes of drawing or writing it is not nearly so well adapted as paper. This reflection suggested some meaning-some relevancy in the death's-head. I did not fail to

observe, also, the form of the parchment. Although one of its corners had been, by some accident, destroyed, it could be seen that the original form was oblong. It was just a slip, indeed, as might have been chosen for a memorandum—for a record of something to be long remembered and carefully preserved."

But," I interposed, "you say that the skull was not upon the parchment when you made

the drawing of the beetle.

How then do you

trace any connection between the boat and the skull-since this latter, according to your own admission, must have been designed (God only knows how or by whom) at some period subsequent to your sketching the scarabæus?"

were sure,

“Ah, hereupon turns the whole mystery; although the secret, at this point, I had comparatively little difficulty in solving. My steps and could afford but a single result. I reasoned, for example, thus: When I drew the scarabæus, there was no skull apparent upon the parchment. When I had completed the drawing I gave it to you, and observed you narrowly until you returned it. You, therefore did not design the skull, and no one else was present to do it. human agency. done.

You,

At this stage of my reflections I endeavored to remember, and did remember, with entire distinctness, every incident which occurred about the period in question. The weather was chilly (oh rare and happy accident!), and a fire was blazing upon the hearth. I was heated with exercise and sat near the table. however, had drawn a chair close to the chimney. Just as I placed the parchment in your hand, and you were in the act of inspecting it, Wolf, the Newfoundland, entered, and leaped upon your shoulders. With your left hand you caressed him and kept him off, while your

right, holding the parchment, was permitted to fall listlessly between your knees, and in close proximity to the fire. At one moment I thought the blaze had caught it, and was about to caution you, but, before I could speak, you had withdrawn 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 colors disappear at longer or shorter intervals after the material written upon cools, but again become apparent upon the reapplica

tion of heat.

"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
