The presentation to our Provincial Museum by Henry Lawson, 
Esq., of three interesting boulders from our fishing banks, 
specially directed attention to the subject of our paper. 
Each of these is adorned by a prominent and singular organ- 
ism, which attracted the attention of the fisherman who found 
them. To the striking and puzzling character of these we are 
indebted for the preservation of the boulders and their attachés. 
The boulders are of Lower Cambrian quartzites. They were 
brought up from a depth of 65 fathoms. Our Museum has a 
number of other boulders from the same banks. Some of these 
we have had for many years. Other interesting ones have been 
received from Mr. Lawson and others, since we began our investi- 
gations. During my glacial researches I have directed the Devil’s 
Island fishermen to bring boulders from the shore of that Island 
and the fishing banks, with or without attaches. Iam thereby 
enabled to ascertain that our glacial transportation had extended 
a considerable distance into the Atlantic. | have already noted 
Thrum Cap and its shoal as the ultima thule of this glacial 
transportation. We are not disposed, on the evidence of our 
boulders, to extend it to 60 or 80 fathoms, or 26 miles beyond 
Thrum Cap or Devil’s Island. This may have been effected by 
bergs or floes from our glaciers, ice sheets, or other causes. It is 
possible that icebergs from Arctic regions, which are often seen 
on our coast, borne along by the Arctic current, may have 
contributed their quota to the boulders of our fishing banks. 
This, however, is only a peradventure. 
Our Boulders are— 
1. Archean Granite, of Halifax.
