ciation with such moraines. Many of the conspicuous peaks, knobs, 

 and hills of the latter are, individually, kames. Belts of kames having 

 the general position, relations, and significance of terminal moraines 

 are called kame moraines. 1 Kames occasionally attain a height of 

 100 feet or more, but heights of 20 to 40 feet are much more common. 

 The stratification of the sand and gravel of which the kames are

 to disturbance with every movement of the edge of the ice, so long 

 as the ice and kames were in contact. The effects of the crowding 

 of the ice are often distinctly seen in the disturbed and crumpled con- 

 dition of the planes of stratification. The stratification was subject 

 to still further disturbance when the ice melted, for in many cases
