island, is low and flat; the acclivity of the inland parts is very
gradual, and the whole country covered with cocoa-nut and bread-fruit
trees. This, as far as we could judge, is the finest part of the island,
and we were afterward told that the king had a place of residence here. At
the south-west extremity the hills rise abruptly from the sea side, leaving
but a narrow border of low ground toward the beach. We were pretty near the
shore at this part of the island, and found the sides of the hills covered
with a fine verdure; but the country seemed to be very thinly inhabited. On
doubling the east point of the island, we came in sight of another snowy
mountain, called Mouna Roa (or the extensive mountain), which continued to
be a very conspicuous object all the while we were sailing along the south-
east side. It is flat at the top, making what is called by mariners table-
land; the summit was constantly buried in snow, and we once saw its sides
also slightly covered for a considerable way down; but the greatest part of
this disappeared again in a few days.

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
