Firo Island on thoodgo of tho .;small lagoon, Horo an area of several 

 hundred yards is in violont agitation, boiling water spurting up 

 through the mud, which gives up a dense stoam and vapor, malting it- 

 impossible to see farther than a few feet. Two pools of \7ater, each 

 about four feet in diameter, are in a state of ezcessive ebullition 

 they are small geysers in fact, as the water is thrown to a height 

 of about five feet by the rapidly escaping steam. On account of the 

 escaping steam and the treacherous character of the ground which could 

 .not be trusted with one's weight, the farther end of this active area 

 cculd not be examined. On tho east side of tho now land where it liad 

 been dished out, and at the edge of the lagoon, there is a group of 

 steaming conical rocks of roccnt formation. The water in the lagoon 

 around these steaming rocks is boiling, but the action is not nearly 

 so violent as at the geysers, 



"A number of sulphur patches were noticed in those places where 

 vapors were rising, 



"Along the western beach abroast of Perry Peak was found a cavc-in 

 about 18 feet in diameter and 15 foot deep; probably very recent, but 

 nothing of iinportance to bo noticed about it. 



"No irregularities wore noticed in tho boat compass, which was 

 observed at different points on the island, and seemod to bo no magnetic 

 influence. 



"The sea lions at Sea Lion Point were just as numerous as formerly, 

 but all the murres which inhabited Fire Island and Castle Rock are gone. 

 In fact there were no birds on the island except a few soa gulls around 

 tho sea lion rookery. The skeltons of murres are scattered over all 

 the island, shovriLng that most of them must have boon killed by tho action 

 of the volcano during the last three months, 



"A nuraber of teniperatiires were taken in the lagoon, and a uniform 

 temperature of 107° F. was obtained except at the extreme northerly end, 

 where it was found to be 90° F. 



"Specimens of lava, pumice, sand, etc., were collected, tempera- 

 tures taken at the placog where fcund, and the specimens labeled as 

 follows : 



" * *"A-' ~ taken at the edge of the lake at the extreme north- 

 west end, Tho temperature of the lake at this point was 90° F, and 

 of the soil 75° F."
