COLE : PHYSICAL GEC»GRAPHY OF THE EAST RIDING.

Sand is sometimes accumulated by the wind into heaps which 
are then known by the name of dunes. Such dunes are common on 
the Lancashire coast, and notably in Holland. In the East-Riding 
they occur at a peculiar point of land, known as Spurn Point. This 
is a sort of natural embankment, 4 miles long, and very narrow, 
bounded by the sea on one side, and by the Humber on the other. 
It is mainly composed of shingle washed out of the Boulder Clay, 
which is ever travelling southwards ; the whole being capped with 
fine sand, which forms a congenial home for certain marine plants, 
whilst the shingle provides a breeding place for terns. 
At the lighthouse at Spurn Point, many interesting notes have 
been taken with respect to the migration of birds, which have been 
embodied in a report given to the British Association, in 1883, by 
Mr. John Cordeaux. 
NOTE ON THE PARALLEL ROADS OF GLEN GLOY. BY REV. E. 
MAULE COLE, M.A. 
Visiting this year some friends on Loch Lochy, a portion of the 
Caledonian Canal, I had an opportunity of examining carefully the 
parallel roads of Glen Gloy, over which my friend's shooting 
extended. Little has been written about Glen Gloy, though a good ' 
deal more has been said about its more illustrious neighbour Glen 
Roy. 
A good summary of the literature on the subject of the parallel 
roads will be found in Sir C. Lyell's Antiquity of Man, with a map 
and sketch. Since then Mr. J. R. Dakyns, of II. M. Geological 
Survey, has published some notes in the Geological Magazine for 
December, 1879, which he kindly sent me, wherein he alludes to a 
paper by Professor Prestwich on the same subject, published in the 
July number of the Geological Magazine of the same year, and also 
to a paper by Sir John Lubbock, in the Q. J. G. S. for 1868, neither 
of which have I seen.
