E., N. 20 W., mag. ; or S. 38 E. ; N. 38 W., true. This is 10 ° differ- 

 ent from the course already observed at the Sugar Refinery opposite 

 Wellington Barracks, and at Brunswick street, Citadel Hill. Part 

 I. This striation corresponds with that of Pleasant Park, which 

 is generally S. 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 off 

 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 S. 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 J x 3 x 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 S. 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. to S. 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 line 

 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
