The beds in the quarry walls appear horizontal, but 

 those in the floor of the quarry show a distinct dip. In one 

 case this is 2 or 3 degrees in a direction almost due south ; 

 in another case, one quarter mile distant, the dip is 2 or 

 3 degrees in a direction due west. The general dip over 

 all the quarries is toward the southwest. 



Grooves and striae trending S 20 E, made by the 

 Keewatin glacier, may be seen on all fresh surfaces, while 

 here and there some striae of the Labradorian glacier 

 may be detected running N 8o° W. 



The presence of the stratified and partially assorted 

 layer between the two boulder clays is indicative of a 

 temporary recession of the ice, although the thinness 

 of the layer and the absence of organic remains would 

 suggest that it was probably local and of short duration.

 INTRODUCTION. 



THE GREAT PLAINS. 



The central part of the continent to the east of the 

 Rocky Mountains is generally referred to as the Great 

 Plains. This name, as applied to the southern portion 

 of the region, is descriptive mainly of its treeless character.
