 the nests are so difficult of access that their 

 occupants, on their way to them, may be seen 

 shding backwards down the little glazed snow- 

 slopes several times before they accomplish the 

 ascent, whilst in other places they have to jump

Even up these heights a tendency to grouping is

 who, seeming to seek seclusion, make their nests 

 at some distance from the others. I noticed this 

 in some places along the shore, too, where solitary 

 nests were to be seen on isolated patches of 

 shingle.
