Glaciers, 203 



ment. From this point each way the motion 

 gradually diminishes until it reaches the sides 

 of the glacier, where the motion is not more 

 than two or three inches. 



The great North American glaciers move at 

 a much higher rat of speed. We are in- 

 debted to Dr. G. Frederick Wright, author of 

 " The Ice Age in North America," who spent 

 a month studying the Muir glacier in Alaska, 

 for many details concerning that great ice 

 river. This glacier empties into Muir Inlet, 

 which is an offshoot of Glacier Bay. It is situ- 

 ated in latitude 58 degrees 50 minutes and 

 longitude 136 degrees 40 minutes west of 

 Greenwich. The bay into which this glacier 

 empties is about thirty miles long and from 

 eight to twelve miles wide. This bay, with 

 its great glacier, has a setting of grand moun- 

 tain peaks. I cannot do better than to quote 

 the words of Dr. Wright when he describes the 

 location of this glacier. Dr. Wright lived for 

 a month in a tent on the edge of this bay, a 

 short distance below the face of the great 

 glacier, where the icebergs fell off every few 

 minutes into the deep water. 



He says : " To the south the calm surface of 

 the bay opened outward into Cross Sound 

 twenty-five miles away. The islands dotting 

 the smooth surface of the waters below us 

 seemed but specks, and the grand vista of 

 snowclad mountains guarding either side of
