which, when projected, intersected at a considerable angle, were 
counted, but since it was not possible to break out the pebbles 
and bowlders for examination on all sides, the count was made from 
observation of the outlines exhibited in a given area of rock surface. 
The results obtained were as follows: 
Total Number of Number of Soled 
Pebbles and Pebbles and Percentage Locality 
Bowlders Bowlders 
205 17 8 Destor Township, Pontiac Co.,

210 37 18 Kekeko Hills, Boischatel Town-

If it had been possible to break out the pebbles and bowlders and 
observe them in three dimensions instead of one, the above per- 
centages would certainly be greatly increased. 
In the preceding discussion of the glacial hypothesis, atten- 
tion has been confined to the conglomerates of the series. One 
of the strongest arguments, however, in favor of Huronian con- 
tinental glaciation is to be found in a comparison of the series as a 
whole, to the Pleistocene glacial, fluvioglacial, and postglacial 
deposits of the same region—for each of these has its exact counter- 
part in the Cobalt series. At the base of the latter, there is the con- 
glomerate, which, like the Pleistocene glacial drift, is exceedingly 
variable in thickness, and like the drift is unstratified, in part, 
resembling till, is rudely sorted and cross-bedded, in part, similar 
to the fluvioglacial deposits of kames, eskers, and outwash plains, 
and, in places, passes into unstratified greywacke containing scat- 
tered pebbles and bowlders, thus duplicating bowlder clay. Over- 
lying the basal conglomerate, there is the stratified greywacke, 
argillite, arkose, and quartzite which have their parallel in the 
Pleistocene postglacial stratified clay and sand of lacustrine
