in the interior of the island. The region around Terrapin Road, 
and for a considerable distance south, is covered by a broad plain 
which slopes gradually upward towards the southwest. There 
are several steep hills on this portion of the island some of which 
probably rise to a height of 500 ft. The color and general ap¬ 
pearance of these hills indicated that they were composed of 
tufa. This part of the island is covered with forests, apparently 
made up of the forms usually found on the dryer parts of these 
islands. 
There is a strip of country south of the wooded arear which is 
covered with beds of basaltic lava on which there is apparently 
little or no vegetation. This is followed on the southwest by 
still another area covered with vegetation, which extends down 
to within possibly three miles of Finger Point. East and south 
of Finger Point the country is again covered with lava, a portion 
of which is evidently volcanic cinders. There are many small 
craters on the lava in this vicinity, fifty of which were counted 
while sailing past this part of the island. 
The country around the northeastern end of the island, and 
for some distance southwest along the east coast, is apparently 
very similar to that around Terrapin Road. We did not get 
very close to this part of the island so no very exact observations 
could be made of its close features. The country around Fresh 
Water Bay, on the south side, is quite steep and is heavily covered 
with dark green vegetation well down towards the shore. A 
stream of water is said to enter the sea at Fresh Water Bay, but 
as there is no good anchorage here it was not visited. 
The interior part of the southern half of the island is a broad 
plateau which varies in elevation from 900-1,600 ft. The pla¬ 
teau is rolling and there are numeros small ravines which have 
streams of water in them during a part of the year. Small 
marshes are formed in some of the lower places in this region 
during the rainy season, but they quickly dry up soon after the 
dry season sets in again. The main central mountain rises to a 
height of 2,100 ft. and is composed of bits of volcanic cinders 
and other fragmentary material all of which is very much decom¬ 
posed. There is no indication of a crater here, the mountain ap¬ 
parently being a huge pile of volcanic debris. A small crater 
lake is located on this plateau but was not visited for botanical 
purposes. 
This island is probably better watered than any other one of
