42 Captain Bayficld on the 
remark that calcspar is abundant in all the orders of rocks. 
That copper, native orin ore, was also found inall, and flu- 
or spar in all but the sandstone. ‘The various slates of the 
submedial order, were only found on the slate islands, and on 
Wedge Island and islets nearit, in Neepigon bay ; unless the 
slate which we sometimes observed under the greenstone as 
at the Pie island, be added. Hence, almost all the formations 
which usually intervene between the granite and the old red 
sandstone are wanting, excepting greenstone, and pe:haps 
the limestone discovered by Doctor Bigsby at ‘Thunder Cape, 
which, as it alternates with the sandstone, is probably transi- 
tion limestone, 
The numerous horizontal depositions above the old red 
sandstone are entirely wanting ; traces of mountain lime- 
stone having alone been observed. 
With respect to the relative ages of the granite and trap or 
overlying rocks, it would be mere hypothesis to give an opi- 
nion, when itis remembered that the origin of these rocks, 
whether igneous or aqueous, is still matter of dispute with 
geologists. 
But we are decided in our opinion thatthe sandstone is of 
posterior formation to all the rest, from the reasons which 
we have before given. 
It appears to us, that at some period, previous to the de- 
position of the shell limestones, a great catastrophe, the na- 
ture of which it would be yain to surmise, has shattered the 
granitic and trap formations. That their fragments were then 
long subjected to the action of rapid streams of water. A pe- 
riod of quiet seems then to have occurred, in which the sand- 
stone was horizontally deposited. Since its deposition, it ap- 
pears to have been only partially disturbed in the vicinity of 
the granite, &c. either by the upheaving in places of that 
rock or by subsidences:
