E., N. 20 W., mag.; or 8.38 E., N. 38 W., true. Thisis 10° differ- 
ent from the course already observed at the Sugar Refinery opposite 
Wellington Barracks, and at Brunswick street, Citadel Hill. Part 
[. This striation corresponds with that of Pleasant Park, which 
is generally 8. 20 E., mag. Paper of 1875-6. Coming to Leahy 
Villa, we find another glaciated exposure. It is 30 years since I 
first discovered this. The appearance is not now so striking as 
it was then. I had heard of Agassiz’s glacial theory and glacia- 
tion before leaving Scotland. This was the first glaciation that 
I had seen. Since then it is very much defaced; the glaciation 
has largely shelled of. I would remark that the position of the 
argillites is vertical. It would be impossible for me to cut oft 
either with hammer or chisel, a piece of unstriated surface, as the 
weather has done, or as I could do this if striated. This 
would seem to indicate that a thin stratum had been formed on 
the ends of the tilted argillites by the pressure of the striating 
agency. Here the prevailing course is 8S. 10 E., mag. — Feeble 
and small striae diverge from this course; grooves occasionally 
run to 30° and return to 20°. Faults are very numerous here 
and elsewhere, varying from 2 to 9 inches. The course is not 
interrupted by these. The north side ascends and then at a con- 
siderable angle, and then it becomes level. Two granite boulders 
lie on this exposure; of these, the largest is 3} x 3x 2 feet. The 
extent of exposure is 300 x 150 feet. Farther on in the drain 
on the north side of the road, is another exposure, having a 
width of 30 feet, and striation course 8.20 E. There are still 
two others before reaching the Bridge. The striation of one has 
been shelled off, the other has a steep northern inclination on the 
surface. Coming to the North West Arm, our course was 
changed from W. toS. W. Here we observed great sections of 
drift. The boulders were granite, gneissoid and argillites, syen- 
ites and diorites and amygdaloids, dioritic and doleritic were 
absent. We entered on a road which I had not previously 
travelled. We were now among granites. Coming into lme 
with Williams's Lake, we suddenly passed into gneissoid rock, 
and then into granite. I recognized an old acquaintance, and 
was on familiar grounds, having followed the gneissoid rocks on
