KAME AREAS IN WESTERN NEW YORK 159 
lations of morainal till, or subsequently either dispersing or bury- 
ing them; and the fact of the heavy glacial drainage, occur to 
mind as possible causes. Another important fact is that the 
bulk of the ground moraine had been left as heavy drumloid 
ridges. . 
The relation of the drumloid and the kame deposits are such 
as to clearly indicate the later deposition of the kames. For 
many reasons the writer has no doubt of the subglacial origin of 
the drumlins and drumloids of western New York, which are 
here regarded as a part of the ground moraine.
