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? lip;ht and dark bands, 

 and suggested that there might be flows of ditferent kinds of lava 

 in this region, each of which presented conditions peculiarly 

 adapted for the growth of certain species of plants. 



The countiy 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 

 pai't of this mountain receives less moisture than does the middle- 

 part. Tile 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 

 Avater and pools of strongly brackish w^ater in the vicinity of the 

 shore and farther inland. 



There were large trees of Avieennia 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 foimd in places, 

 in the vicinity of the shore and there are quite a number of small 

 trees of Hibiscus tiliaceus, and bushes of Tournefortia rufo-seri- 

 cea. 



The vegetation on the inland country consists of plants usu- 

 aly found in the dry regions except tliat there is an unusually
