STATHER : A STRIATED SURFACE AT SAXDSEXD. 485 
yards of the upper surface of the " Dogger " sandstone had, for 
quarrying purposes, been cleared of its covering of drift, and on 
tlie hard sandstone surface thus exposed striae and other indications 
of glacial action were clearly visible. One slab of rock, about a yard 
square, washed clean by the rain, showed the striae particularly 
well, and the whole of the adjacent surface, so far as it could be seen, 
had the rounded and smoothed appearance peculiar to glaciated 
rock. The direction of the striae was 35 degrees west of north. 
Other Localities. 
Perhaps it may be of interest, in connection with the above 
note, to recall a few particulars regarding the striated surfaces 
previously recorded on the Yorkshire coast. 
In 1891 Mr. G. W. Lamplugh recorded striae on the south side 
of Filey Car Naze. Direction of striae, 20 degrees east of north. 
In 1896 Messrs. Sheppard and MuH described a striated surface 
at Robin Hood's Bay. Direction of striae, exactly north. 
In 1896 the writer recorded a large striated surface at Filey 
on the north side of the Car Naze. Direction of striae, 24 degrees 
east of north.

Inferences. 
From the above it will be seen that the direction of the striae 
varies with the locality in a very significant way. And the variation 
is the more remarkable when it is remembered, that at each of the 
three localities the direction of the ice-flow, as shown by the markings, 
is from a quarter that is now the open sea ; and that, although the
