STATHER : A STRIATED SURFACE AT SANDSEND. 
adjacent land seems to have had some influence in deflecting the 
movement, the course of the main ice-stream has been almost parallel 
to the coast, and therefore transverse to the slope of the land. This 
direction would have been impossible unless the North Sea basin 
had been choked with ice to a level somewhat higher than that of 
the adjacent shores. It is clear from the striae that the general 
flow has been southward along the sea-floor, but with a constant 
tendency to creep in westward upon the coast. It is also clear that 
the upland buttress of the Oolitic rocks, which has its eastern corner 
on the coast at Whitby, has caused the ice-flow to swerve through 
an angle of 60 degrees in rounding it. 
These conclusions are strongly confirmatory of the views as 
to the " East British " ice-sheet which Mr. Kendall has deduced, 
from the study of the glacial marginal phenomena of the interior 
of the Oolitic uplands, views which are too well known to this Society 
to need recapitulation here.
