The extremely well defined ebb of May 1904 observed at Sc 8 is apparent in the 

 exceptionally low waterlevel at S Skag 8 during that month.

the ebb during its early part corresponds to the phenomenon known to meteorologists 

 as the retardation of the annual heat- and cold-maxima. The disturbance in the hydro- 

 graphic periodicity, evinced by the postponement of the flooding, answers to another 

 most important phenomenon, viz. the occurrence of warm winters in northern Europe.
