According to the tropical line of snow, as determined by Mr. Condamine, from observations taken on the Cordilleras, this mountain must be at least 16,020 feet high, which exceeds the height of the Pico de Teyde, or Peak of Teneriffe, by 724 feet, according to Dr. Heberden’s computation, or 3,680, according to that of the Chevalier de Borda.  The peaks of Mouna Kaah appeared to be about half a mile high; and as they are entirely covered with snow, the altitude of their summits cannot be less than 18,400 feet.  But it is probable that both these mountains may be considerably higher.  For in insular situations, the effects of the warm sea air must necessarily remove the line of snow in equal latitudes, to a greater height than where the atmosphere is chilled on all sides by an immense tract of perpetual snow.

The coast of Kaoo presents a prospect of the most horrid and dreary kind; the whole country appearing to have undergone a total change from the effects of some dreadful convulsion.  The ground is every where covered with cinders, and intersected in many places with black streaks, which seem to mark the course of a lava that has flowed, not many ages back, from the mountain Roa to the shore.  The southern promontory looks like the mere dregs of a volcano.  The projecting head-land is composed of broken and craggy rocks, piled irregularly on one another, and terminating in sharp points.

Notwithstanding the dismal aspect of this part of the island, there are many villages scattered over it, and it certainly is much more populous than the verdant mountains of Apoona.  Nor is this circumstance hard to be accounted for.  As these islanders have no cattle, they have consequently no use for pasturage, and therefore naturally prefer such ground as either lies more convenient for fishing, or is best suited to the cultivation of yams and plantains.  Now amidst these ruins, there are many patches of rich soil, which are carefully laid out in plantations, and the neighbouring sea abounds with a variety of most excellent fish, with which, as well as with other provisions, we were always plentifully supplied.  Off this part of the coast we could find no ground, at less than a cable’s length from the shore, with a hundred and sixty fathoms of line, excepting in a small bight to the eastward of the south point, where we had regular soundings of fifty and fifty-eight fathoms over a bottom of fine sand.  Before we proceed to the western districts, it may be necessary to remark, that the whole east side of the island, from the northern to the southern extremity, does not afford the smallest harbour or shelter for shipping.

The south-west parts of Akona are in the same state with the adjoining district of Kaoo; but farther to the north, the country has been cultivated with great pains, and is extremely populous.
