April 16. I finished the ladder; so I went up with the ladder to the top, and then pulled it up after me, and let it down on the inside: this was a complete enclosure to me; for within I had room enough, and nothing could come at me from without, unless it could first mount my wall.
The very next day after this wall was finished, I had almost had all my labour overthrown at once, and myself killed; the case was thus: As I was busy in the inside of it behind my tent, just in the entrance into my cave, I was terribly frighted with a most dreadful surprising thing indeed; for on a sudden I found the earth come crumbling down from the roof of my cave, and from the edge of the hill, over my head, and two of the posts I had set up in the cave cracked in a frightful manner: I was heartily scared, but thought nothing of what was really the cause, only thinking that the top of my cave was falling in, as some of it had done before; and for fear I should be buried in it, I ran forward to my ladder, and not thinking myself safe there neither, I got over my wall for fear of the pieces of the hill which I expected might roll down upon me. I was no sooner stept down upon the firm ground, but I plainly saw it was a terrible earthquake, for the ground I stood on shook three times at about eight minutes distance, with three such shocks, as would have overturned the strongest building that could be supposed to have stood on the earth; and a great piece of the top of a rock, which stood about half a mile from me next the sea, fell down with such a terrible noise as I never heard in all my life: I perceived also the very sea was put into violent motion by it; and I believe the shocks were stronger under the water than on the island.
I was so amazed with the thing itself, having never felt the like, or discoursed with any one that had, that I was like one dead or stupified; and the motion of the earth made my stomach sick, like one that was tossed at sea; but the noise of the falling of the rock awaked me, as it were, and rousing me from the stupified condition I was in, filled me with horror, and I thought of nothing then but the hill falling upon my tent and all my household goods, and burying all at once; and this sunk my very soul within me a second time.
After the third shock was over, and I felt no more for some time, I began to take courage, and yet I had not heart enough to get over my wall again, for fear of being buried alive, but sat still upon the ground, greatly cast down and disconsolate, not knowing what to do. All this while I had not the least serious religious thought, nothing but the common “Lord have mercy upon me!” and when it was over, that went away too.
While I sat thus, I found the air overcast, and grow cloudy, as if it would rain; soon after that the wind rose by little and little, so that in less than half an hour it blew a most dreadful hurricane: the sea was all on a sudden covered over with foam and froth, the shore was covered with the breach of the water, the trees were torn up by the roots, and a terrible storm it was; and this held about three hours, and then began to abate, and in two hours more it was stark calm, and began to rain very hard.
All this while I sat upon the ground, very much terrified and dejected, when on a sudden it came into my thoughts, that these winds and rain being the consequence of the earthquake, the earthquake itself was spent and over, and I might venture into my cave again: with this thought my spirits began to revive, and the rain also helping to persuade me, I went in and sat down in my tent; but the rain was so violent, that my tent was ready to be beaten down with it; and I was forced to go into my cave, though very much afraid and uneasy, for fear it should fall on my head.
This violent rain forced me to a new work, viz. to cut a hole through my new fortification like a sink, to let water go out, which would else have drowned my cave. After I had been in my cave some time, and found still no more shocks of the earthquake follow, I began to be more composed; and now, to support my spirits, which indeed wanted it very much, I went to my little store, and took a small sup of rum, which however I did then and always very sparingly, knowing I could have no more when that was gone.
It continued raining all that night, and great part of the next day, so that I could not stir abroad; but my mind being more composed, I began to think of what I had best do, concluding, that if the island was subject to these earthquakes, there would be no living for me in a cave, but I must consider of building me some little hut in an open place, which I might surround with a wall as I had done here, and so make myself secure from wild beasts or men: but concluded, if I staid where I was, I should certainly, one time or other, be buried alive.
With these thoughts I resolved to remove my tent from the place where it stood, which was just under the hanging precipice of the hill, and which, if it should be shaken again, would certainly fall upon my tent. And I spent the two next days, being the 19th and 20th of April, in contriving where and how to remove my habitation.
The fear of being swallowed up alive, made me that I never slept in quiet, and yet the apprehension of lying abroad without any fence was almost equal to it; but still, when I looked about and saw how every thing was put in order, how pleasantly concealed I was, and how safe from danger, it made me very loth to remove.
