Our guns were loaded only with small shot, so that we could hope to make but little impression on the body of a wild animal.  The roar was repeated, and there was a loud rustling among the penguin grass on a mound near us.  The grass moved rapidly.  We looked towards it. Presently the huge head of a ferocious-looking animal appeared glaring at us from among the grass.  We shouted lustily for help to our friends.
