The part of the island visited on tlie 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 alonj; 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 Penuisetum 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 width. 



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 ancliorage 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, w^here thickets of bushes made up of Crypto- 

 carpus pyrifoi-mis. 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
