In some cases the rocks presented a polished surface with 

 numerous fine scratches, in others there are groovings a few 

 inches broad, and perhaps one or two deep. In other places, 

 again, there are deep troughs scooped out of the surface rock. 

 One of the most interesting series of troughs is just north of the 

 ''Peak," at Dundas (at a height of 516 feet above Lake On- 

 tario). Here the clayey earth has been removed, and the sur- 

 face presents the appearance of a series of crests and troughs 

 of waves, having a distance between the crests of about eight 

 feet, with a depth varying from half to one foot — the direction of 

 these is about S 65^^ W. Their surfaces are smoothed and polished 

 and are again striated by several sets which cross them at small 

 angles in a more western line. These ice-markino-s continue in 

 straight lines, scratching both the troughs and crests (of the 

 large grooves) equally. In some cases I have noticed acute 

 bendings of the striations.
