GLACIAL DISTRIBUTION IN CANADA—HONEYMAN. XVil 
uation of that of Quebec Province, and my investigations have 
given it an Atlantic terminus. 
Ottawa Gneisses (C.)—On a visit to Ottawa, in May, 1882, I 
observed massive boulders of Archean gneisses in a number of 
places. At the Rifle Ranges I examined them more particularly. 
Some of the gneisses were beautifully banded, others of them 
contained abundance of magnetite. In Sir W. Logan’s table, 
the course of the glacial grooves at Rideau River, Stegman’s 
Rapids, and also at Barrack Hill, is S. 45 E., true meridian. 
Defining this course on Vennor’s Map, I found that a N. 45 W. 
extension passed between the Hull and Laycock Magnetite [ron 
Mines. According to the same table, at Hull the glacial grooves 
run 8. 45 E. This is certainly a satisfactory coincidence. 
Kingston Gneisses (D) Archwan.—When I was at the Domin- 
ion Exhibition at Kingston, in September, 1882, my attention 
was directed to the large quantity of boulders which lay about 
the. exhibition grounds. The greater part of them corresponded 
with the Ottawa boulders, with the exception of the magnetic 
ones, and were consequently Archean. One boulder was of 
Trenton Limestone, and was glaciated. Looking for glaciation in 
situ, I found it on the limestones at the edge of the water near 
the entrance to the Royal Military College. The course of the 
grooves was S. 54 W. magnetic. The direction observed by Sir 
W. E. Logan was S. 45 W., true meridian, while “other grooves 
run 8.85 E.” Trenton Limestone is the formation on which 
Kingston is built, and of which it is built. Hence it is called 
“the Limestone City.” In the approach to it, near the Rideau 
Canal, the Archewan (Laurentian) is seen with the Trenton Lime- 
stone lying directly upon it, in the same way as on the Railway 
from Montreal to Ottawa, near the latter. We have now reached 
long. 76° 25’ to 29’, and lat. 44° 14 to 19’. In long. 80° 54’, lat. 
44° 28’, is the last of the south-easterly grooves (S. 5 E.), accord- 
ing to Logan. In long. 79° 33’, lat. 46° 10’, is Nipissing Lake. 
Here, and beyond all grooves are, therefore, S. W. Lake Temis- 
camang, long. 79° 26’ to 30’, lat. 47° 7 to 36’, has glaciation 
generally 8. E. This is the region of divergence as well as of 
watershed,
