Robinson Crusoe by Daniel Defoe Chapter 12 Page 10

In this frame of thankfulness I went home to my castle, and began to be much easier now, as to the safety of my circumstances, than ever I was before: for I observed that these wretches never came to this island in search of what they could get; perhaps not seeking, not wanting, or not expecting anything here; and having often, no doubt, been up the covered, woody part of it without finding anything to their purpose. I knew I had been here now almost eighteen years, and never saw the least footsteps of human creature there before; and I might be eighteen years more as entirely concealed as I was now, if I did not discover myself to them, which I had no manner of occasion to do; it being my only business to keep myself entirely concealed where I was, unless I found a better sort of creatures than cannibals to make myself known to.
