I sent my boat to sound, but found no ground.
The 18th Cape Mabo bore south, distance nine leagues; by which account it lies in the latitude of 50 minutes south, and meridian distance from Cape St.George one thousand two hundred and forty-three miles.

St.John's Isle lies forty-eight miles to the east of Cape St.George; which being added to the distance between Cape St.George and Cape Mabo, makes one thousand two hundred and ninety-one meridional parts; which was the furthest that I was to the east.

In my outward-bound voyage I made meridian distance between Cape Mabo and Cape St.George, one thousand two hundred and ninety miles; and now in my return, but one thousand two hundred and forty-three; which is forty-seven short of my distance going out.

This difference may probably be occasioned by the strong western current which we found in our return, which I allowed for after I perceived it; and though we did not discern any current when we went to the eastward, except when near the islands, yet it is probable we had one against us, though we did not take notice of it because of the strong easterly winds.

King William's Island lies in the latitude of 21 minutes south, and may be seen distinctly off Cape Mabo.
In the evening we passed by Cape Mabo; and afterwards steered away south- east half-east, keeping along the shore, which here trends south-easterly.
