On the whole, the agreement between the evidence 

 given by the smaller vertical hauls at the mouth of the 

 Bay and that of the much larger surface hauls obtained 

 on the same occasions is satisfactory, but naturally the 

 vertical hauls sometimes yield additional information. 



Our total plankton curve for the Bay did not this 

 year rise to quite such a high point in the vernal 

 maximum as that reached in the spring of 1913, but on 

 the other hand the autumnal maximum was greater in 

 1914, and, in fact, the curve remains at a higher level 

 from August onwards to the end of the year (fig. 1).
