They are situated between the Latitude of 16° 10′ and 16° 55′ S., and between the Longitude 151° 00′ and 151° 42′ W. from the Meridian of Greenwich. Ulietea and Otaha lay close to each other, and are both inclosed within a Reef of Coral Rocks; and altho' the distance between the one and the other is near 2 Miles, yet there is no Passage for Shipping. By means of this reef are form'd several excellent Harbours. The entrance into them are but narrow, but when a Ship is once in nothing can hurt her. Those on the East side have been already described. On the West side of Ulietea, which is the largest Island of the 2, are 3, the Northermost of which, called Oraotanue,[1] we lay in, the Channell leading in is a ¼ of a Mile wide and lies between 2 low sandy Islands, which are the Northermost small Islands on this side. You have good Anchorage between or just within the 2 Islands in 28 fathoms soft ground. This harbour, tho' but small, yet it is preferable to any on the Island, on account of the easy getting of fresh Water, and being seated in the most fertile part of the Island. The other 2 harbours lay to the Southward of this, and not far from the S. end of the Island. In both of them are good Anchorage in 10, 12, and 14 fathoms water: they are readily known by 3 small woody Islands that lay at their entrance, the Southermost Harbour lies within and to the Southward of the Southermost Island, and the other lies between the Northermost. There are more Harbours at the South End of this Island, as I am inform'd, but these were not examind by us.
Otaha affords 2 very good Harbours, one on the E. and the other on the W. side; that on the E. side called Ohamane[2] hath been already mentioned, the other is called Oharurua,[3] and lies about the middle of the S.W. side of the Island. It is pretty large, and affords good Anchorage in 20 and 25 fathoms, and there is no want of fresh Water. The breach in the Reef which forms a Channell into this harbour is ¼ of a mile broad, steep too, on both sides, and the same may be said of all the others, and in general there is no danger but what is Visible.
The Island of Bolabola lies N.W. by W. from Otaha, distant 4 Leagues, it is incompassed by a reef of Rocks and several small Islands, and the Circuit of the whole appear'd to be about 8 Leagues. On the S.W. side of the Islands (as I am inform'd) is an opening in the Reef which admits of a Channell into a very good Harbour. This Island is very remarkable on account of a high Craggy hill upon it, which Terminates at Top in 2 Peaks, one higher than the other; this hill is so perpendicular that it appears to be quite inaccessible. The land on Ulietea and Otaha is of a very hilly, broken, and uneven surface, except what borders upon
