winds were probably prevailingly westerly, the prevailing 
direction at present being rather more south-westerly.” 
I have to thank Mr. Brooks also for drawing my attention to a 
paper on the subject. 4 5 A westerly or west-north-westerly 
wind would have carried pollen across the Dogger Bank from 
places where the counties of Yorkshire and Lincolnshire now 
stand. 
Other evidence as to age may come to light : in the meantime 
one may surmise that at least a portion of the Dogger Bank was 
above sea level as late as Neolithic times.

takes two years to reach full growth, then it is evident that the ledge of Moorlog full of half-grown 
specimens must have been exposed to the sea continuously for one year, but not for longer.
