But to go on. After I had thus secured one part of my little living stock, I went about the whole island, searching for another private place to make such another deposit; when, wandering more to the west point of the island than I had ever done yet, and looking out to sea, I thought I saw a boat upon the sea, at a great distance. I had found a perspective glass or two in one of the seamen’s chests, which I saved out of our ship, but I had it not about me; and this was so remote that I could not tell what to make of it, though I looked at it till my eyes were not able to hold to look any longer; whether it was a boat or not I do not know, but as I descended from the hill I could see no more of it, so I gave it over; only I resolved to go no more out without a perspective glass in my pocket.
