STERNA HIRUNDO : WILSON'S TERN. 367 



the " frying-pan and the fire " that can be found in 

 nature. 



" The descent of a Tern upon its victim is performed 

 with inimitable ease and grace. The bird frequently 

 disappears entirely beneath the surface, and occasionally 

 even swims a short distance under water before reap- 

 pearing. The flight of the Roseate Tern is especially
