EARTHQUAKE OF SEPTEMBER THIRD 351 



an hour, and the tide only rose subsequently to half the height indicated 

 by the tide tables, evidently because of the same uplift of the shoreline 

 observed by Mr. Doverspike. There was a roar and the schooner trembled. 



At Kayak Island and Katalla, on Controller Bay, 170 miles west of 

 Yakutat, the shocks were also felt and there were great avalanches^^ and 

 dust clouds. 



Cape Whitshed. — At the Coast and Geodetic Survey camp west of the 

 Copper Elver delta, 220 miles west of Yakutat, the shocks observed by 

 H. P. Eitter and E. B. Latham came at 2.40 p. m.^^ These Cape Whit- 

 shed observations, at a point whose exact location is known (longitude 

 145° 54' 35" west, latitude 60° 27' 34" north) and timed with a good 

 and well-rated chronometer, constitute the most valuable local records of 

 these earthquakes. At only two other points within the shaken area are 

 the time records capable of correction to the standard Greenwich mean 

 time and comparable with the precise times of the seismograph records. 



The shock lasted two minutes and was a violent earthquake — direction 

 northeast and southwest — turning floating bottles toward the northeast 

 and throwing the water in a shallow creek out on the bank. The weather 

 was clear, pleasant, and warm. All the movements were apparently lat- 

 eral and eight or more after-shocks were felt. One at 3h. 22m. 30s. had 

 a few seconds' duration. The time of two light shocks during the after- 

 noon was not noted. A shock at 6h. 45m. lasted ten seconds. Two quite 

 severe shocks came at 7h. 10m., lasting five seconds. Two moderate 

 shocks occurred at 7h. 44m., having a duration of ten seconds, and there 

 were several light ones after this before the Coast Survey observers fell 

 asleep. 



Chugach Mountains. — On the Tsina Eiver, 210 miles northwest of 

 Yakutat, at al)out 2 p. m., Capt. AY. E. Abercrombie, of the IT. S. Army, 

 felt a succession of shocks which tripped him while walking, caused 

 groves of cottonwoods to wave like wheat, started heavy landslides, and 

 damaged glaciers. 



In another part of the Chugach ^fountains, 240 miles northwest of 

 Y'akutat, Lieut. W. C. Babcock noted the commencement of the earth- 

 quakes at 2.28 p. m.^^ The shock began gently, gradually increased in 

 violence until it was impossible to stand erect, and then gradually de-
