GREAT EARTHQUAKE OF SEPTEMBER TENTH 371 



of Yakutat, the great shock of September 10 was also felt.^^ Judge H. H. 

 Folsom, the United States commissioner, recorded this shock at 12.55 

 p. m. It lasted long enongh for him to get out of a barber's chair, walk 

 20 feet to the sidewalk, and watch electric light poles sway. Buildings 

 were shaken severely, especially the hotel, hospital, and churches, but no 

 serious damage was done. Frightened people ran into the streets. Miners 

 emerged hastily from the Treadwell gold mine at Douglas. Douglas and 

 Juneau together had 2,689 inhabitants in 1900 and presumably about the 

 same the year before, and only low wooden buildings. There were minor 

 tremblings all day and another severe shock between 4 and 5 p. m. 



Southeastern Alaska. — ^Tn Taku Inlet, southeast of Juneau, the earth- 

 quake was probably severe, "^^ damaging the glaciers so that increased ice- 

 berg discharge began at once, as in the Glacier Bay and Icy Straits re- 

 gions. Several of the fiords of the Inside Passage, "^^ including Lynn 

 Canal, Taku Inlet, Stephens Passage, and Gastineau Channel, were ob- 

 structed by ice. This resulted temporarily in difficulties in navigation, 

 one vessel, the Rosalie, being damaged by collision with floating icebergs. 

 The Taku Inlet glaciers seemed in 1905 to have recovered from their 

 1899 losses.'^ The net advance of Taku Glacier between 1890 and 1905, 

 as proved by photographs,^^ may possibly be ascribed to earthquake ava- 

 lanching in 1899, the snowfield being so augmented that although the 

 tidal ice-front temporarily retreated, because of shaking and water dis- 

 turbances, the glacier itself has eventually advanced, as those in Yakutat 

 Bay have done. 



At Sumdum, in southeastern Alaska, 275 miles southeast of Yakutat, 

 Mr. R. V. Rowe, a carpenter, observed an earthquake on an unrecorded 

 date in September, 1899, which caused a building he was erecting to rock 

 for about ten seconds. 



In McHenry Inlet, Etolin Island, Alexander Archipelago, 375 miles 

 southeast of Yakutat, Mr. Fred Patching reports a sharp earthquake 

 about 6.30 a. m. a Sunday morning in September, 1899, in connection 

 with which great landslides occurred. This location is detached from 

 the main shaken area and, because doubtful, has not been put on the map.
