sometimes built along the edge of the ice and left there upon 

 its retreat as a distinct narrow ridge forming the outer bank of 

 the river bed. A beautiful example of this kind occurs on the 

 west slope of Dry hill between Hartsville and New Marlboro. 

 There are three of these river beds at this locality, with vertical 

 intervals of fifteen or twenty feet. The lower one is the most

strongly developed and has an outer morainic ridge or bank like 

 •a parapet or levee running, with occasional breaks, for two miles 

 or more. It runs along the hillside half a mile east of the 

 Konkapot river and about 130 feet above it. Fig. 4 is a view 

 from the hillside looking southwest across this river bed, which 

 is here about 200 feet wide. The meadow and the cornfield are 

 on the floor of the channel, beyond which the stony parapet ridge 

 may be seen rising ten feet or more above the channel floor. 

 This type of lateral moraine, however, is rarely seen, the more 

 common type being the smooth submarginal form.
