I mused on these phenomena for some time, and could not forbear calling upon God to protect me from the devil; who must, as I imagined, have a hand in such unaccountable things as they then seemed to me. But at length reason got the better of these foolish apprehensions, and I began to think there might be some natural cause of them, and next to be very desirous of finding it out In order to this I set about making experiments to try what would run to the rock and what would not. I went into the captain's cabin, and opening a cupboard, of which the key was in the door, I took out a pipe, a bottle, a pocket-book, a silver spoon, a tea-cup, &c, and laid them successively near the rock; when none of them answered, but the key which I had brought out of the cupboard on my finger dropping off while I was thus employed, no sooner was it disengaged but away it went to it. After that I tried several other pieces of iron-ware with the like success. Upon this, and the needle of my compass standing stiff to the rock, I concluded that this same rock contained great quantity of loadstone, or was itself one vast magnet, and that our lading of iron was the cause of the ship's violent course thereto, which I mentioned before.
This quite satisfied me as to my notions of spirits, and gave me a more undisturbed night's rest than I had had before, so that now, having nothing to affright me, I passed the time tolerably well in my solitude, as it grew by degrees familiar to me.
I had often wished it had been possible for me to climb the rock, but it was so smooth in many places and craggy in others, and over-hanging, continuing just the same to the right and left of me as far as ever I could see, that from the impossibility of it, I discharged all thoughts of such an attempt.
I had now lived on board three months, and perceived the days grow shorter and shorter, till, having lost the sun for a little time, they were quite dark: that is, there was no absolute daylight, or indeed visible distinction between day and night; though it was never so dark but I could see well enough upon deck to go about.
What now concerned me the most was my water, which began to grow very bad (though I had plenty of it) and unsavoury, so that I could scarce drink it, but had no prospect of better. Now and then indeed it snowed a little, which I made some use of, but this was far from contenting me. Hereupon I began to contrive; and having nothing else to do, I set two open vessels upon deck, and drawing water from the hold I filled one of my vessels, and letting it stand a day and a night I poured it into the other, and so shifted it every twenty-four hours; this, I found, though it did not bring it to the primitive taste and render it altogether palatable, was nevertheless a great help to it, by incorporating the fresh air with it, so that it became very potable, and this method I constantly used with my drinking-water, so long as I stayed on board the ship.
It had now been sharp weather for some time, and the cold still increasing, this put me upon rummaging the ship farther than ever I thought to do before; when opening a little cabin under deck, I found a large cargo of fine French brandy, a great many bottles, and some small casks of Madeira wine, with divers cordial waters. Having tasted these, and taken out a bottle or two of brandy, and some Madeira, I locked up my door and looked no farther that time.
The next day I inquired into my provisions, and some of my flesh having soaked out the pickle, I made fresh pickle and closed it up again. I that day also found several cheeses cased up in lead, one of which I then opened and dined upon: but what time of day or night it was when I eat this meal I could not tell. I found a great many chests well filled, and one or two of tools which some years after stood me in a very good stead, though I did not expect they would ever be of that service when I first met with them.
In this manner I spent my time till I began to see broad daylight again, which cheered me greatly. I had been often put in hopes during the dark season that ships were coming towards me, and that I should once more have the conversation of mankind, for I had by the small glimmering seen many large bodies (to my thinking) move at a little distance from me, and particularly toward the reappearing of the light, but though I hallooed as loud as I could, and often fired my gun, I never received an answer.
When the light returned, my days increased in proportion as they had before decreased; and gathering comfort from that, I determined to launch my small boat and to coast along the island, as I judged it, to see if it was inhabited and by whom; I determined also to make me some lines for fishing, and carry my gun to try for other game, if I found a place for landing; for though I had never, since my arrival, seen a single living creature but my cat, except insects, of which there were many in the water and in the air before the dark weather, and then began to appear again, yet I could not but think there were both birds and beasts to be met with.
Upon launching my boat I perceived she was very leaky, so I let her fill and continue thus a week or more to stop her cracks, then getting down the side of my ship I scooped her quite dry and found her very fit for use; so putting on board my gun, lines, brandy bottles, and clothes chest for a seat, with some little water and provisions for a week, I once more committed myself to the sea, having taken all the observation I could to gain my ship again if any accident should happen, though I resolved upon no account to quit sight of the rock willingly.
