Boulders Composed of Conglomerate. 



From the description of the Temiskaming series, on a 

 preceding page, it will be seen that it, like the Cobalt series, 

 consists of fragmental rocks, ranging from greywackes fine 

 in grain to coarse conglomerates. Probably the most re- 



Conglomerate of Cobalt series, containing- a conglomerate boulder 

 from the Temiskaming series. 



markable boulders in the conglomerate of the Cobalt series 

 are those of conglomerate from the Temiskaming series. If 

 the latter series has furnished conglomerate boulders to the 

 former, undoubtedly it has supplied pebbles or boulders of 

 quartz and other minerals and rocks which once were con- 

 stituents of its cono-lomerates.
