The part of the island visited on the northeast side, is about 
opposite Tagus Cove. There is a small bay at this place around 
which there are small mangrove swamps, as there are at several 
other places along the east and south shores of the island. Bot¬ 
anical conditions were even more discouraging here than they 
were on the north side, as all of the country in this vicinity was 
found to be covered with beds of recent lava on which there was 
apparently no other vegetation than occasional specimens of Cer- 
eus nesioticus and Cyperus Mutisii. 
Mr. Beck succeeded in reaching the top of the mountain, when 
he visited the island from the south side somewhat earlier in the 
season. He reported it to be heavily covered with vegetation, 
among which were ferns and other mesophytic plants. He also 
reported a heavy growth of tall grass around the top, which 
from his description, must have been Pennisetum exalatum. 
There are two lakes inside the crater which are probably 2,000 
ft. or more below the rim. The inner walls were covered with 
recent lava. 
Seymour Islands. 
The Seymour Islands, three in number, lie off the northeast 
corner of Indefatigable Island of which they probably formed a 
part some time in the past. The islands are all low and are 
separated from each other by relatively narrow and shallow 
channels. South Seymour, the only one of the three visited, is 
the largest and lies closest to Indefatigable from which it is sep¬ 
arated by a channel about one half mile in wddth. 
The shores of this island are steep and formed by low cliffs, 
except in two places on the west side, where there are sand 
beaches. One of these beaches borders a rather large bay which 
affords good anchorage for vessels. Back of this bay there is a 
flat sandy area of some extent, but otherwise the surface of the 
island is covered with large irregular boulders of lava in be¬ 
tween which there is a scanty light red soil. 
The densest vegetation on the island occurs on the sandy area 
mentioned above, where thickets of bushes made up of Crypto¬ 
carpus pyriformis, Discaria pauciflora, and Maytenus obovata 
are to be found. In front of these thickets, there is a consider¬ 
able area along the beach which is covered with Ammophila 
arenaria, the only place on the islands where this species has 
been found. The remainder of the island is covered with small
