catastrophe which has left similar, but often far more striking, 
traces of its violence in other countries. And they not only 
afford us proof of the diluvial flood; they lead us, further, to be- 
lieve that the overwhelming torrent swept across this peninsula 
nearly in a north and south direction; such being always the 
direction of these detached and drifted débris from the distant 
and parent ledges with which they claim a common origin. 
The boulders of granite also afford additional evidence of the 
same fact ; for they are never met with on the Worth mountains, 
which present nothing extraneous of any character, but are abun- 
dantly scattered about in the opposite direction. If natives of 
the country, as they appear to be, they also must have originated 
from some part of the South mountain range, where the granite 
is now in place and forms beds to a very considerable extent, as 
may be seen on the map. 
In the “ Reliquie Diluviane,” of Professor Buckland, we find 
the granite boulders of Nova Scotia cited among the many other 
proofs he has ably and ingeniously brought forward in support of 
the diluvial current. If to these boulders of granite, we now add 
those of the trap unknown to this author, or not mentioned by 
his informant (Sir Alexander Croke), we may safely conclude, in 
his own language, “ that the present position of these fragments 
can be accounted for only by supposing them to have been drift- 
ed from the nearest granite [and trap] districts, by the same 
- rush of waters that transported those mentioned by Dr. Bigsby, 
in the districts of Lake Huron and Lake Erie.”* Of the other evi- 
dences mentioned by him, such as valleys of denudation, the fur- 
rows or parallel scratches upon the surfaces of rocks, and vast
