Mr. Beck, are covered with a tangled growth of bushes and morn¬

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 Point, • 
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 which 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
