 for the sitting bird refused to change her position, and 

 lowering her long neck and half closing her eyes, settled

 throated Divers, and we did not discover the other nest. 

 I should have liked to have spent more time amongst 

 these birds, but the nesting season is so short ; and as I 

 had decided to spend the whole of the summer in trying 

 to secure the life-history of the Cuckoo in photographs, 

 I had to hurry south.
