 were crushed and in part they became embedded 

 in the front, bottom, and sides of the ice. This 

 rock-set front tore into the sides and bottom of 

 its channel after it had made a channel ! 

 with a terrible, rasping, crushing, and grinding 

 effect, forced irresistibly forward by a pressure 

 of untold millions of tons. Glaciers, large and 

 small, the world over, have like characteristics 

 and influences. To know one glacier will enable 

 one to enjoy glaciers everywhere and to appre- 

 ciate the stupendous influence they have had 

 upon the surface of the earth. 



They have planed down the surface and even 

 reduced mountain-ridges to turtle outlines. In 

 places the nose of the glacier was thrust with
