CHAP. xvir. BLACK SCOTER. 203

 ploTer on the morrow. We turned to look towards the spot 

 of our encounter with the former : the whole flock had re- 

 turned to it ; they looked like great black terns on the wing 

 as they hoyered over it, with their peculiar kestrel- or tern-

 and the sun got low down in the horizon, for of course it

 spot near a deserted house called Boogree, and soon after 

 landing we shot a black scoter off her nest. It contained 

 six eggs and an abundance of down ; it lay in a little hollow 

 sloping towards the river, and was entirely concealed amongst 

 dwarf birch. The scoter does not breed apparently on
