Samuel Franklin Emmons 



In 1870 he discovered on the slopes 

 of Mt. Shasta the first actual glaciers 

 known to exist in the United States; 

 and in their study made observations 

 that are credited with first suggesting 

 the true origin of the kettle-holes and 

 kames of New England. His later 

 discovery in the summer of 1874, that 

 a line of islands along the southern 

 coast of New England formed a part of 

 its terminal moraine, had much influ- 

 ence in inducing the later systematic 

 studies of the continent. 1 glacier. 



The field-work of the Survey wrs 

 completed in 1873, but it was 1877 

 before the respective specialists had 

 been able to work up the amount of 

 material gathered, for it was one of 

 King's fundamental principles that 

 abundant collections should be made 

 in the field to illustrate all the natural 

 phenomena observed, and the litho- 

 logical collections alone numbered- 

 about five thousand specimens.
