 seconds are reported for May 20 and 23 by the keeper of the light 

 at Scotch Cap on Unimak Island, and a ' pretty severe shake ' occurred 

 at Dutch Harbor on June 2, but nothing is reported for April or early 

 May, when the new island must have risen. Certainly there could not 

 have been any activity displayed by Makushin or Akutan, both of which 

 volcanoes overlook Unalaska and Dutch Harbor, without being observed 

 by the people of these villages. Perhaps the rise of such an island, 

 in a more or less plastic condition, as it must be, would not necessarily 

 be attended by disturbance in the solid crust of the neighboring islands. 

 On the Pribilof Islands, which had an origin similar to that of the 

 Bogoslofs, no earthquake shock or other disturbance was noted, although

these islands were affected at the time of the rise of New Bos;oslof in 

 1883. The Pribilof group lie 120 miles to the north of the Bogoslofs. 



On the whole, however, the weight of evidence at present seems to 

 favor the idea that the Bogoslof disturbance of 1906 was local in char- 

 acter and the coincidence in date with the California earthquake in- 

 volves no actual relation between the two phenomena. 



The writers first saw the islands of Bogoslof in July, 1896, while 

 en route for the Pribilof Islands in connection with the fur seal investi- 

 gations. The U. S. Fish Commission Steamer Albatross attempted to 

 land the commission on Old Bogoslof, but was prevented by the heavy 

 surf, and the thick weather made only a partial view of the islands 

 possible. The vessel afterwards passed the islands on its way to the
