THE JURASSIC COAL OF SPITZENBERGEN 95 



for doubt that the great northward drift has some influence on 

 the climate of West Spitzbergen, for the conditions along the 

 westerly shore are much more tolerable than those on Bear 

 island, 150 miles south, but exposed to a southward drift. At 

 the same time the conditions are not such as Mohr supposed, 

 for he seems to have imagined the surface densely covered as in 

 the Saragasso sea. For 1 50 miles along the west coast, the 

 water during August of 1904 showed few and small patches of 

 seaweed and the amount stranded on the shore is utterly insig- 

 nificant ; so that even had there been a Gulf Stream during the 

 Jurassic, its seaweed would not have been an important factor 

 in coal-making.
