them. It was noticed from the shore that the vegetation had a 
streaked appearance about half way up the side of the mountain. 
It appeared to be made up of alternating light and dark bands, 
and suggested that there might be flows of different kinds of lava 
in this region, each of which presented conditions peculiarly 
adapted for the growth of certain species of plants. 
The country around the top of the mountain was examined 
through a field glass on a clear day later in the season as we 
were sailing past this part of the island. The vegetation ap¬ 
peared to be smaller than lower down and it was rather grayish 
in color instead of dark green. It is very likely that the upper 
part of this mountain receives less moisture than does the middle 
part. The upper part of this mountain could be plainly seen 
from the top of the mountain at Villamil when we visited there. 
The lower part of the mountain, however, was entirely hidden 
by the fog at this time. It was also noticed that much of the soil 
on top of the Villamil mountain was dry while lower down it 
was wet. The fog banks apparently hang low when they strike 
the islands. 
Turtle Cove. 
Turtle Cove is on the south side of the island about six miles; 
west of Villamil. The coast in this vicinity is low and rocky 
with occasional sand beaches, while back of the coast the coun¬ 
try is low and covered with beds of basaltic lava for a consider¬ 
able distance inland. There are springs of comparatively fresh 
water and pools of strongly brackish water in the vicinity of the 
shore and farther inland. 
There were large trees of Avicennia officinalis on the sand 
beach where we landed, back of which there is a swampy area 
covered with a dense growth of Conocarpus erectus and trees of 
Rhizophora Mangle. Rhizophora occurs for some distance in¬ 
land, surrounding the pools of brackish water. It also occurs in 
isolated patches on the open coast, but owing to the fact that the 
surf breaks heavily here at times, none of these are extensive. 
Thickets of Laguncularia racemosa are also to be found in places; 
in the vicinity of the shore and there are quite a number of small 
trees of Hibiscus tiliaeeus, and bushes of Tournefortia rufo-seri- 
cea. 
The vegetation on the inland country consists of plants usu- 
aly found in the dry regions except that there is an unusually
