of the moraine. It appears to have been deposited by a 

 river flowing westward along the ice front in the last or 

 closing phase of the relatively long pause during which the 

 moraine was built. The ice had ceased advancing apparently 

 and had become practically inert along its edge. The river 

 during this phase had fallen a little below the passage to 

 Willcocks' lake and probably escaped southward through 

 the gap east of Tinton. 



Two miles east of Willcocks' lake there are well-de- 

 veloped eskers and associated troughs cutting through the 

 southern moraine from southeast to northwest. These also 

 show with great clearness that the ice here was moving to- 

 ward the northwest, normal to the trend of the moraine at 

 this place. The esker stream cut through the moraine and 

 issued into the drainage channel a mile and a half northeast 

 of Willcocks' lake.
