 who has lived at Meiringen all his life, has often 

 told me that these birds always build there under

 and natural habit, and have not been tempted by 

 the buUdings which man erects. But this year we 

 were able to show Anderegg several nests built 

 under the eaves against timber, and he was obliged 

 to believe the evidence of his own eyes. It may be 

 that this had been going on some time unnoticed by 

 him; it had become a fixed idea in his mind that 

 the bird buUds in one way, and it would not occur
