are quite remarkable. The depth of some of the lakes like 
the Temiscouata, the Squatook and the Cabano, occupying 
as they do north and south depressions and with nearly 
fiat bottoms, would seem to point to ice-movements as 
having been closely connected with their position and 
character. But what is of still greater interest is the 
evidence which the district everywhere affords, of a 
northern as well as a southern driftage at some time during 
the ice period, the great ridge becoming itself a centre or 
axis of ice distribution as it is now of the rivers which 
drain it. This fact is strikingly seen in the occurrence of 
great boulders of fossiliferous Silurian limestone strewed 
over the Quebec rocks at the upper end of Lake Temis- 
couata, and which have been derived from Mount Wissick 
to the south, again in the similar occurrence of such boulders 
at the northern end of Lake Metapedia, and finally their 
occurrence, in large numbers, along the St. Lawrence shore, 
as noticed about the Grand Métis river and Rimouski. 
Similar facts have elsewhere been observed by Mr. Chalmers, 
and are referred to in his reports on the Superficial Geology 
of the district. 
Of the early human period, but few relics, so far as known 
to the writer, have yet been found in the region here con- 
sidered. None were observed by us around the shores of 
Temiscouata Lake, but near the outlet of the First Tuladi 
Lake, are numerous fragments of chipped flint, together 
with a few sherds of pottery, indicating the former presence 
here of the early Pre-Historic races. So also we have 
failed to find any relics of this character on the St. John 
river above Edmunston, although below that point, and 
especially about Grand Falls and Aroostook Falls, they are 
not uncommon,
