CH. III. OLD NEST OF OSPREY. 37 



fattening on the oat and pea fields, the Gray lag 

 goose (Anser ferus) has already laid, and is nearly 

 hatching her eggs, in the wilds of Sutherland. In 

 one island, containing a few stunted birch-trees, we

Wilson mentions that in America the osprey

 suitable for the purpose. I have been told, how-
