THE KILLER. 



Chap. III. 



Once only have I seen these dreaded monsters ; when in 

 the crow's-nest contemplating the chequered surface of ice 

 and sea, some eight or ten of them swam rapidly past us, 

 close to the surface, and occasionally displaying out of 

 water the whole of their very remarkable dorsal fin, which 

 appeared to be at least four or five feet in length. 



The crow's-nest.
