It is high water in this Bay at full and change of the Moon about 8 o'clock, and the tide at these times rises and falls upon a perpendicular 6 or 8 feet.

It appears, from the few Observations I have been able to make of the Tides on the Sea-Coast, that the flood comes from the Southward, and I have lately had reasons to think that there is a current which comes from the Westward and sets along shore to the South-East or South-South-East, as the Land lays.
[Sail from Bay of Islands, New Zealand.] Wednesday, 6th.

P.M., had a Gentle breeze at North-North-West, with which we kept turning out of the Bay, but gain'd little or nothing; in the evening it fell little wind; at 10 o'Clock it was Calm.

At this time the tide or Current seting the Ship near one of the Islands, where we were very near being ashore; but, by the help of our Boats and a light Air from the Southward, we got clear.

About an hour after, when we thought ourselves out of all danger, the Ship struck upon a Sunken rock* (* Called Whale Rock, in Endeavour's chart.) and went immediately clear without receiving any perceptible damage.
