steppe, between the Dirt Hills aud the Wood}- Mountains. By far the 

 greater number of the bowlders in all these localities consists of 

 Laurentian gneiss, man}' of them are angular, although the majority 

 are prett}' well rounded. In each of the above districts, the bowlders 

 are so numerous, over considerable areas, that a man might walk upon 

 them in an}' direction without touching the ground. 



In going from the northwest angle of the Lake of the Woods, toward 

 Fort Garry, the road for long distances, runs upon low ridges of lime- 

 stone-gravel between swamps, until reaching the drier ground between 

 the White Mouth river and Oak Point, and in this interval, bowlders 

 and pebbles of light-coloi'ed limestone are very common. They are 

 also strewn abundantly on the shores around the southwestern part of 

 Lake of the Woods. In the northern part of Lake of the Woods, and 

 in the region of the Winnipeg and English rivers, limestone fragments 

 are extremely rare, so that their sudden appearance, in such abundance, 

 to the West and South of the northwest angle, would appear to indi- 

 cate the occurrence of this rock in situ in the immediate neighborhood.

 drained by the Winnipeg river, are as follows:
