On another portion, the surface of which slopes down towards 
north at an angle of about 35°, the direction of the strise is due

Each set of striae might he produced by the same agent. If its 
normal direction was W.N.W., it would, on striking the rock 
which slopes down north, he deflected into an E. and W. 
direction. 
(3) A still more remarkable case of the same kind occurs in 
a cutting of the North British Railway, about half a mile to 
the west of Linton station. The rock is on the south side of the 
line. The smoothed surface is about 18 feet high and 25 feet in

length. The surface there slopes down northwards at an angle 
of from N. 11° W. to N. 20° W. The striae run across the 
rocky surface in a direction E. 15° N. — the deflection from the 
normal direction of the striating agent being greater here than at 
Linton village, on account of the larger area of the opposing surface. 
It may be added that, whilst in the lower part of the rocky sur- 
face, the striae are horizontal, near the top of the rock they rise up 
towards the east at an angle of 4° or 5°. If the striating agent 
consisted of a mass of drift, the pebbles and blocks in the lower 
part would move horizontally, and produce horizontal striae. But
