Mr. Selby on the Birds of the Farn Islands. 455 



in the Dean and Chapter of Durham, but leases are granted, re- 

 newable from time to time upon payment of a fine. This lease 

 has lately passed into the hands of the society above mentioned, 

 and we indulge the hope that they will afford to the feathered in- 

 habitants that protection which has been withheld for some years 

 past, to the manifest diminution of their numbers. By so doing 

 they will not only entitle themselves to the thanks of the Ornitho- 

 logist, and such strangers as from curiosity annually visit these 

 islands, but they will eventually render them of more intrinsic 

 value by the great increase of the produce, consisting of feathers, 

 eggs, and eider-down.

This species is met with upon all the Islands, where it is 

 a permanent resident. It breeds in the clefts and upon the shelves 

 of rocks, the nest is composed of the decayed stalks of such 

 grasses as grow here. Marine insects and flies constitute its food.
