Killer whale secured for the ISIuseimi. This species wages a continual warfare upon the gray whale 

 and often assists the human hunters by frightening the gray whales so badly that they turn on their 

 backs and lie motionless at the surface of the water 



The spout of the flnbadk whale rises to a height of from fifteen to twenty feet. It is exceedingly 

 difficult to photograph imless as in the present case, there happen to be mountains to form a dark back- 

 ground. Finbacks can undoubtedly swim faster than any other large whale, probably reaching a maxi- 

 mtmi speed of thirty-five miles per hour
