The words of the most recent investigator of the first rank, 
quoted on pages 145 to 148 below, show how these difficulties

obtained are more certain, for there the country is more open and 
settled, and has been frequently visited by a large number of 
geologists.

in the vicinity of Lake Temiscouata,^ but Bailey and Mclnnes 
improved somewhat on the earlier description, and I quote 
from their work :' 
"The following section is a condensation of that in the Geology 
of Canada [p. 420], with such additional information as has 
been recently obtained. The section begins on the north side 
of Mount Wissick or Mount Lennox, where the rocks of the 
Silurian system may be seen to rest unconformably upon those

"Greenish grey and black slates. . . . These beds occur on 
the north-east side of a small cove above Mt. Wissick and are 
part of a similar series of rocks, supposed to be of the same age 
as those of Point Levis, which occupy all the upper part of the 
lake. They have been subjected to much crumpling, and ex- 
hibit considerable irregularity of inclination, their dip, where 
nearest to the Silurian, being N. 40° W. <^70°— 80°. They have 
as yet yielded no fossils, and their thickness is unknown.
