An opening in the land is laid down near Cape Dombey in the French charts, before which are placed the Barthelemy Islands, which certainly do not exist, and it was not until after the haze of the day cleared up that two detached quadrilateral shaped hills were seen over the low land; and as these at a distance would assume exactly the figure and appearance of islands they must have been the cause of the mistake; I have therefore called them (by altering the nomenclature as little as possible) the Barthelemy Hills.
At nine o'clock, having weighed at daylight, we reached within three miles of Tree Point; when the ebb tide commenced and obliged our anchoring to wait the turn of tide, in order to examine an opening that trended deeply in to the southward.

Accordingly when the flood made we got under weigh, and entered the opening without encountering any difficulties or being impeded by shoals.

The deepest channel is about two-thirds over on the eastern side, in which we sounded on a muddy bottom in between nine and five fathoms; after having passed the narrowest part we hauled over to the western shore, in the hope of finding anchorage out of the strength of the tide, but it was with great difficulty, and not until darkness compelled us, that we let go the anchor, upon what appeared to be a hard stony bottom, in five fathoms.
The tide then turned to the ebb and commenced running out so rapidly that we were under apprehensions of the vessel being left dry.
September 6 to 7.
But at low water which took place at 1 hour 20 minutes a.m., although the tide had fallen twenty-two feet, it left nine feet, which depth was just sufficient to float the vessel.

Upon stirring up the bottom with an oar, it was found to be of stiff clay, plentifully sprinkled with small iron-stone gravel; it proved however to be of much better quality than had been suspected, and the anchorage was retained during our stay.
As the bottom of this port had a river-like appearance, Mr.Roe prepared to examine it, and set out at daylight accompanied by Mr.Cunningham: they did not return until the following day.
From his report it appears that the shores are overrun with mangroves (rhizophoreae) and that the whole of the back lands are inundated at high water, which accounts for the very strong tides we experienced.

The bottom of the port, which at Mr.Roe's desire was named in compliment to Vice Admiral Sir Richard G.Keats, G.C.B., is divided into two saltwater arms, extending towards the foot of a range of thickly-wooded hills, which were seen from the anchorage over the low mangrove shore, and which, from their description, are probably connected with the Barthelemy Hills.
