ON THE ORNITHOLOGY OF LAPLAND. 275

 with us about three days, when, I suppose, not 

 liking the appearance of the place, they migrated

 days they were brought in to me by a boy who 

 had shot them. This was adding a new fact to

 these birds had come up here to breed, it must have 

 been like the carrion crow in a solitary manner. 



I never saw the magpie (Pica caudata, Ray) 

 up at Quickiock, but they are occasionally met 

 with at lockmock.
