26 GLACIAL GRAVELS OF MAINE. 



The immense amount of earth involved in the Willey Shde in the 

 Crawford Notch, and in several other large slides in the White Mountains, 

 which were from one-half mile to near 3 miles long, makes it certain that 

 there must have been a vast amount of friction of the moving fragments 

 against one another and against the underlying rock. The motion of the 

 landslip is very much more rapid than that of any glacier, and this would be 

 favorable to the scratching and faceting of stones. No one appears to have 

 reported finding such stones under circumstances showing conclusively 

 that they were formed during the slip.
