In the middle of these cogitations, apprehensions, and reflections, it came into my thoughts one day that all this might be a mere chimera of my own, and that this foot might be the print of my own foot, when I came on shore from my boat: this cheered me up a little, too, and I began to persuade myself it was all a delusion; that it was nothing else but my own foot; and why might I not come that way from the boat, as well as I was going that way to the boat? Again, I considered also that I could by no means tell for certain where I had trod, and where I had not; and that if, at last, this was only the print of my own foot, I had played the part of those fools who try to make stories of spectres and apparitions, and then are frightened at them more than anybody.
Now I began to take courage, and to peep abroad again, for I had not stirred out of my castle for three days and nights, so that I began to starve for provisions; for I had little or nothing within doors but some barley-cakes and water; then I knew that my goats wanted to be milked too, which usually was my evening diversion: and the poor creatures were in great pain and inconvenience for want of it; and, indeed, it almost spoiled some of them, and almost dried up their milk. Encouraging myself, therefore, with the belief that this was nothing but the print of one of my own feet, and that I might be truly said to start at my own shadow, I began to go abroad again, and went to my country house to milk my flock: but to see with what fear I went forward, how often I looked behind me, how I was ready every now and then to lay down my basket and run for my life, it would have made any one have thought I was haunted with an evil conscience, or that I had been lately most terribly frightened; and so, indeed, I had. However, I went down thus two or three days, and having seen nothing, I began to be a little bolder, and to think there was really nothing in it but my own imagination; but I could not persuade myself fully of this till I should go down to the shore again, and see this print of a foot, and measure it by my own, and see if there was any similitude or fitness, that I might be assured it was my own foot: but when I came to the place, first, it appeared evidently to me, that when I laid up my boat I could not possibly be on shore anywhere thereabouts; secondly, when I came to measure the mark with my own foot, I found my foot not so large by a great deal. Both these things filled my head with new imaginations, and gave me the vapours again to the highest degree, so that I shook with cold like one in an ague; and I went home again, filled with the belief that some man or men had been on shore there; or, in short, that the island was inhabited, and I might be surprised before I was aware; and what course to take for my security I knew not.
Oh, what ridiculous resolutions men take when possessed with fear! It deprives them of the use of those means which reason offers for their relief. The first thing I proposed to myself was, to throw down my enclosures, and turn all my tame cattle wild into the woods, lest the enemy should find them, and then frequent the island in prospect of the same or the like booty: then the simple thing of digging up my two corn-fields, lest they should find such a grain there, and still be prompted to frequent the island: then to demolish my bower and tent, that they might not see any vestiges of habitation, and be prompted to look farther, in order to find out the persons inhabiting.
These were the subject of the first night's cogitations after I was come home again, while the apprehensions which had so overrun my mind were fresh upon me, and my head was full of vapours. Thus, fear of danger is ten thousand times more terrifying than danger itself, when apparent to the eyes; and we find the burden of anxiety greater, by much, than the evil which we are anxious about: and what was worse than all this, I had not that relief in this trouble that from the resignation I used to practise I hoped to have. I looked, I thought, like Saul, who complained not only that the Philistines were upon him, but that God had forsaken him; for I did not now take due ways to compose my mind, by crying to God in my distress, and resting upon His providence, as I had done before, for my defence and deliverance; which, if I had done, I had at least been more cheerfully supported under this new surprise, and perhaps carried through it with more resolution.
This confusion of my thoughts kept me awake all night; but in the morning I fell asleep; and having, by the amusement of my mind, been as it were tired, and my spirits exhausted, I slept very soundly, and waked much better composed than I had ever been before. And now I began to think sedately; and, upon debate with myself, I concluded that this island (which was so exceedingly pleasant, fruitful, and no farther from the mainland than as I had seen) was not so entirely abandoned as I might imagine; that although there were no stated inhabitants who lived on the spot, yet that there might sometimes come boats off from the shore, who, either with design, or perhaps never but when they were driven by cross winds, might come to this place; that I had lived there fifteen years now and had not met with the least shadow or figure of any people yet; and that, if at any time they should be driven here, it was probable they went away again as soon as ever they could, seeing they had never thought fit to fix here upon any occasion; that the most I could suggest any danger from was from any casual accidental landing of straggling people from the main, who, as it was likely, if they were driven hither, were here against their wills, so they made no stay here, but went off again with all possible speed; seldom staying one night on shore, lest they should not have the help of the tides and daylight back again; and that, therefore, I had nothing to do but to consider of some safe retreat, in case I should see any savages land upon the spot.
Now, I began sorely to repent that I had dug my cave so large as to bring a door through again, which door, as I said, came out beyond where my fortification joined to the rock: upon maturely considering this, therefore, I resolved to draw me a second fortification, in the manner of a semicircle, at a distance from my wall, just where I had planted a double row of trees about twelve years before, of which I made mention: these trees having been planted so thick before, they wanted but few piles to be driven between them, that they might be thicker and stronger, and my wall would be soon finished. So that I had now a double wall; and my outer wall was thickened with pieces of timber, old cables, and everything I could think of, to make it strong; having in it seven little holes, about as big as I might put my arm out at. In the inside of this I thickened my wall to about ten feet thick with continually bringing earth out of my cave, and laying it at the foot of the wall, and walking upon it; and through the seven holes I contrived to plant the muskets, of which I took notice that I had got seven on shore out of the ship; these I planted like my cannon, and fitted them into frames, that held them like a carriage, so that I could fire all the seven guns in two minutes' time; this wall I was many a weary month in finishing, and yet never thought myself safe till it was done.
When this was done I stuck all the ground without my wall, for a great length every way, as full with stakes or sticks of the osier- like wood, which I found so apt to grow, as they could well stand; insomuch that I believe I might set in near twenty thousand of them, leaving a pretty large space between them and my wall, that I might have room to see an enemy, and they might have no shelter from the young trees, if they attempted to approach my outer wall.
Thus in two years' time I had a thick grove; and in five or six years' time I had a wood before my dwelling, growing so monstrously thick and strong that it was indeed perfectly impassable: and no men, of what kind soever, could ever imagine that there was anything beyond it, much less a habitation. As for the way which I proposed to myself to go in and out (for I left no avenue), it was by setting two ladders, one to a part of the rock which was low, and then broke in, and left room to place another ladder upon that; so when the two ladders were taken down no man living could come down to me without doing himself mischief; and if they had come down, they were still on the outside of my outer wall.
Thus I took all the measures human prudence could suggest for my own preservation; and it will be seen at length that they were not altogether without just reason; though I foresaw nothing at that time more than my mere fear suggested to me.
WHILE this was doing, I was not altogether careless of my other affairs; for I had a great concern upon me for my little herd of goats: they were not only a ready supply to me on every occasion, and began to be sufficient for me, without the expense of powder and shot, but also without the fatigue of hunting after the wild ones; and I was loath to lose the advantage of them, and to have them all to nurse up over again.
For this purpose, after long consideration, I could think of but two ways to preserve them: one was, to find another convenient place to dig a cave underground, and to drive them into it every night; and the other was to enclose two or three little bits of land, remote from one another, and as much concealed as I could, where I might keep about half-a-dozen young goats in each place; so that if any disaster happened to the flock in general, I might be able to raise them again with little trouble and time: and this though it would require a good deal of time and labour, I thought was the most rational design.
Accordingly, I spent some time to find out the most retired parts of the island; and I pitched upon one, which was as private, indeed, as my heart could wish: it was a little damp piece of ground in the middle of the hollow and thick woods, where, as is observed, I almost lost myself once before, endeavouring to come back that way from the eastern part of the island. Here I found a clear piece of land, near three acres, so surrounded with woods that it was almost an enclosure by nature; at least, it did not want near so much labour to make it so as the other piece of ground I had worked so hard at.
