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 same 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 a few piles to be driven between them, that they should 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 continual 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 got seven on shore out of the ship. These, I say, I planted like my cannon, and fitted them into frames, that held them like a carriage, that so I could fire all the seven guns in two minutes’ time. This wall I was many a weary month a-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 way 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 monstrous thick and strong, that it was indeed perfectly impassable; and no men, of what kind soever, would 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 hurting himself; 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 present supply to me upon every occasion, and began to be sufficient to me, without the expense of powder and shot, but also without the fatigue of hunting after the wild ones; and I was loth to lose the advantage of them, and to have them all to nurse up over again.

To 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 under ground, 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 great deal of time and labor, 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 for. 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, endeavoring 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 labor to make it so as the other pieces of ground I had worked so hard at.

I immediately went to work with this piece of ground, and in less than a month’s time I had so fenced it round, that my flock, or herd, call it which you please, who were not so wild now as at first they might be supposed to be, were well enough secured in it. So, without any farther delay, I removed ten young she-goats and two he-goats to this piece. And when they were there, I continued to perfect the fence, till I had made it as secure as the other, which, however, I did at more leisure, and it took me up more time by a great deal.
