In 1900 the cutte^ reported that the heat had died o\it on Fire 

 Island, A passage between the two islands was found ¥/ith not less 

 than 7 fathoms of Water, 



Between 1900 and 1904 the island was visited by cutters Tirhich 

 reported few marked changes until latter part of 1905 a new peak 

 appeared half way between the two islands. This peak was connected 

 with Fire Island and left a passage between it and Castle Island 

 with a least depth of 5 fathoms. 



Early in 1906 the island was survGyed by officers of the Cutter 

 PERRY, The now poak was called Perry Peak. It was still separated 

 from old Bogoslof by q channel about 7 fathoms deep but cornioctod v/ith 

 Eire Island. In 1/fciy 1906 the U.S,S. Albatross visited tho island and 

 observed the now steaming volcano. During tho lattor part of 1906 tho 

 cuttor found that another poak was formed filling tho space betwoon Porry 

 Peak and Castle Island, this again making ono island of the group. 



In 1907 a local trader visited the island and found that the 

 additional peak had forraod. This was later found by the McCullock in 

 July of tho same year and that one peak had half collapsed and that 

 the chaimel between it and Castle Rock had filled up with McCullock 

 Peak, estimated 500 feet high. In October the McCullock again visited 

 the island. McCullock peak was gone and a hot water lagoon was in its 

 place, the other poak still stood, Tho average life of the two now 

 peaks in the middle were aboit 10 months. 



In July 1908 tho Cutter RUSH visited the island and the officers 

 made another survey, Pprry Poak had disappcarod_> a high ridgo of land 

 had bcdn found oxtendihg from Eire Island to Castlo Rock with a iraximum 

 height of 300 foot,' the Castlo Rock entrance had boon closed and a 

 now entrance near Fiics Island had boon found. 



In 1909 tho cuttor visited tho island but no important change 

 occurred. 



From this point on extracts of reports are qiiotod giving cyo- 

 witncss accounts of the existing changes. 



Report of Captain E, J, Haake, U.S.R.C.S., Commanding Revenue 

 Cutter PERRY on observations of Bogoslof Isl.and: - June 15-16, 1910, 



"The formation of Bogoslof Island has undergone considerable 

 chojige since our visit last year. The two small islets reported last 

 year as havingcome up in the lake^ have united and risen to a height 

 of about 185 feet above the lake level, and extended to and joined tho 

 N.E. shore strip forining a neck of land extending into the lake in a S.W, 

 direction: tho shore strip on tho N.E, side had also risen about ten 

 feet above last year's height. Castle Rock, Fire Island, and the S.W. 

 shore of the lake remain the same as last year. In the lake, which is 

 salt water, we found temperatures rai:ging from 52 to 110 degrees. On 

 the now land tho most active portion is on its west side where consider- 

 able sulphur fTjmes and boiling water are emitted from small holes in tho 

 ground, Thore is no crater formation, and only at ono spot on top
