ON CONTINENTAL WATERS 251 



Germany, and Schleswig-Holstein hold a distinct 

 advantage in this respect, because of the extra- 

 ordinary numbers which follow these coasts during 

 spring and autumn. 



Herr Gatke, whose observations on the island of 

 Heligoland cover a considerable number of years, 

 testifies to the intensity of this migratory movement 

 over the North Sea in spring and autumn ; and 

 there is certainly no more favourable spot for 

 observing the passage of fowl than on this interesting 

 little island. It is to be regretted that fowlers, as a 

 rule, do not devote more attention to the subject of 

 migration, and record their experiences in some 

 systematic form in their diaries. For scientific as well 

 as sporting purposes such material would prove useful 

 and interesting.
