Mr. Beek, are covered with a tangled growth of bushes and morn- 

 ing glory vines. 



The conditions on this side of the mountain are such that it 

 is very difficult to determine the extent in elevation of the botan- 

 ical regions, the nature of the soil being such as to cause xerophy- 

 tic plants to predominate higher up than would probably be the 

 case if the lower part of the mountain was covered with a more 

 suitable soil. The transition region evidently begins around an 

 elevation of 1,200 ft. and it probably extends up to within about 

 500 ft. in elevation, from the top of the mountain. 



Iguana Cove. 



Iguana Cove is a slight identation in the shoreline on the 

 southwest side of the island. It is somewhat protected from the 

 direct action of the swell, but owing to its small size, it does not 

 afford an anchorage inside. The anchorage is just outside the 

 cove, but owing to the fact that there are jagged rocks projecting 

 from the water a short distance from it, on which the swell 

 breaks heavily, it is dangerous to anchor here except in calm 

 weather. The shores are precipitous in this vicinity, being made 

 up of bluffs, which in places rise to a height of 200 ft. These 

 tall bluffs do not come down to the shore, however, except in one 

 place ; in other places there is a low flat plain intervening be- 

 tween them and the shore. In the vicinity of Christopher Pointy 

 just north of the cove, the shores are made up of low lava cliffs,, 

 and the country back of them is covered with rather recent lava 

 on which there is apparently very little vegetation. In the im- 

 mediate vicinity of Christopher Point there are many small cra- 

 ters and blowholes which rise fifty or more feet in height, and 

 which give the surrounding country a weird and grotesque ap- 

 pearance. South of the cove the shores are made up of low 

 cliffs with occasional shelving beaches of gravel and sand. 



The mountain northeast of Iguana Cove is a broad flat-topped 

 crater Avliich probably rises to a height of 5,000 or more feet. As 

 the weather was very bad when this place was visited, no attempt 

 was made to reach the top of the mountain. The sides are very 

 steep here, and are covered with a considerable amount of soil, 

 composed of disintegrated lava and vegetable mold, which sup- 

 ports a heavy growth of vegetation. The north side of the moun- 

 tain is not so steep and is covered with beds of barren lava in
