It was the sixth of November, in the sixth Year of my Reign, or my Captivity, which you please, That I set out on this Voyage, and I found it much longer than I expected; for though the Island it self was not very large, yet when I me to the East Side of it, I found a great Ledge of Rocks lye out above two Leagues into the Sea, some above Water, some under it; and beyond that, a Shoal of Sand, lying dry half a League more; so that I was oblig'd to go a great Way out to Sea to double the Point.
When first I discover'd them, I was going to give over my Enterprise, and come back again, not knowing how far it might oblige me to go out to Sea; and above all, doubting how I should get back again; so I came to an Anchor; for I had made me a kind of an Anchor with a Piece of a broken Graplin, which I got out of the Ship.
Having secur'd my Boat, I took my Gun, and went on Shore, climbing up upon a Hill, which seem'd to over-look that Point, where I saw the full Extent of it, and resolv'd to venture.
In my viewing the Sea from that Hill where I stood, I perceiv'd a strong, and indeed, a most furious Current, which run to the East, and even came close to the Point; and I took the more Notice of it, because I saw there might be some Danger; that when I came into it, I might be carry'd out to Sea by the Strength of it, and not be able to make the Island again; and indeed, had I not gotten first up upon this Hill, 1 believe it would have been so; for there was the same Current on the other Side the Island, only, that it set off at a farther Distance; and I saw there was a strong Eddy under the Shore; so I had nothing to do but to get in out of the first Current, and I should presently be in an Eddy.
