2. Boulders Carried by Ice, (Perley’s Report on the Fisheries of 
New Brunswick, p. 26).—Off the ‘western part of Shippagan Island, 
within the Bay of Chaleur, there is an extensive shallow flat, extending 
nearly two miles from the land, called the Grand Batture. On 
this flat, there are numerous large blocks or boulders firmly imbedded, 
which render i it dangerous to cross, even wit a fishing boat ; the wrec 
canoe. ‘These boulders are brought over from the wild and mountain- 
ous shores of Caspe, directly across the bay, by the huge masses of 
floating ice, driven over by the northerly gales which ground upon the 
Grand Batture, and there melting, add the rocks they bring, to those 
already deposited. With reference to this m moving of rocks by ice, Mr. 
ilson mentioned that there was formerly a very large. oul directly i in 
front of his landing place, at Miscow, which was much in the way of his 
boats, and against which, in stormy weather, they had often received 
damage. But the severe winter of 1848—49, caused ne ice to — an 
unusual strength and thickness near the shore of Miscow: and w t 
moved off in the spring, it carried off this large rock to deposi it tee, 
he hoped, it would be less troublesome.
