IX. The Cause of the Mig'ration Movement (pp 142-148). 



Heligoland is a small island at the mouth of the Elbe in the North Sea, 

 about fifteen miles distant from the mainland. It is triangular in outline, 

 slightly over a mile in length, but much less than a square mile in area. 

 The little island lies at the intersection of two prominent lines of migra- 

 tion, the one a north and south route, the other an east and west route. 

 Herr Gaetke has studied the subject of migration of birds and bird life at 

 at all seasons at his great observatory, with little cessation or interruption 

 day after day and night after nigiit for the last fifty yoars. He tells us 

 and we can realize the fact that Heligoland stands pre-eminent as an 

 ornithological observatory in the west of Europe. The number of birds 

 observed in Heligland at 398. We owe much to Herr Gaetke's devotion to 

 ornithology for tiie important contribution to our knowledge of the ways 

 of birds. --C. F. H."
