rrxaritima, Lycinm sp., Scaevola Plumieri, Sesuvium Edmon- 
stonei, and S. portnlacastrnm grow quite commonly, while at the 
west end of the bay there is a small swamp of Rhizophora 
Mangle. A short distance back of the bay there is a small lake, 
the water in which has become saturated with salt and a layer 
has crystalized out which is thick enough in places to support 
one’s weight. A number of trees of Avicennia officinalis grow 
in the water on the edge of this lake. There is a heavy growth 
of pneumatophores and mats of Sesuvium Edmonstonei in the 
water beneath these trees. There are some exposures of lava 
in this vicinity on which there is little vegetation besides Cacti 
and a few bushes. Around the base of a small crater, near the 
east end of the bay, there are bushes of Acacia macracantha, Cor- 
dia lutea, Cryptocarpus pyriformis, and Scalesia villosa. There 
is another small crater, about a half mile inland, the sides of 
which seemed to be covered with Bursera trees and Croton 
bushes. 
Post-Office Bay. 
Post Office Bay lies about two miles west of Cormorant Bay* 
just mentioned. This bay derives its name from the fact that 
the British Warship Leander placed a barrel on a post there 
many years ago, in which vessels which visited this place could 
deposit letters. The next vessel that called was supposed to 
take them out and carry them to their next port of call. Sever¬ 
al of the members of the party, including the writer, mailed let¬ 
ters here which reached their destination some eighteen months 
later. 
The interior region, on the north side of the island, was visited 
from this place, and was found to be much rougher than was the 
region near Black Beach Road on the west side of the island. 
There are several small craters on this part, the highest one vis¬ 
ited having an elevation of 700 ft. There are broad valleys be¬ 
tween the craters in some of which there were low rocky areas 
which might have contained water at some time as there were 
rounded boulders in them which had the appearance of having 
been water-worn. 
The coast, along the south side of the bay, is rocky with occa¬ 
sional sand beaches on which there are a few patches of Rhizo¬ 
phora Mangle, and trees of Avicennia officinalis. This, by the 
way, is the only place on the islands where Avicennia grows so
