EXAMINATION in detail reveals many interesting and important 
points that have not been noticed in preceding papers. To some 
of these I now propose to direct attention. 
BEDFORD BASIN. 
Having now resided a year and a half about half way up 
Bedford Basin, I have had favourable opportunities for studying 
the geology of this beautiful and picturesque region. Again and 
again I have referred to Navy Island, on the east side of the 
Basin, as having a glacial deposit of the “Cow Bay Type,” re- 
plete with triassic and archaean boulders. To the north and 
south of this, from Bedford to the Narrows, expanses of drift 
have been examined of similar constitution. 
The greatest breadth as well as depth of the Basin is between 
the Navy Island side and Birch Cove. The breadth here is two 
miles, and one of the Admiralty soundings, about: midway, is 
84 fathoms—/( Vide Chart). As might be expected, its marine 
zoology is very interesting. This year its mackerel fishery has 
been very productive, and many singular fishes, especially scom- 
beresox saurus, have heen found in its waters.
