"I know what they are saying," whispered Jerry.  "Well, these are two strange beings!  How could they have come here?  They are not seals, that's certain, for they have legs; but they don't look as if they could swim with those long, thin projections instead of flappers; and assuredly they can't fly, for they have no wings.  How can they feed themselves, for they have no bills? and see what great ugly round things they've got for heads.  Evidently they cannot dive or live under water. They are not fish, then, nor birds; for if those are feathers growing on their backs, they are very rugged and dirty.  Well, we pity them; for they are strange beasts, that's a fact."  This quaint notion of Jerry's tickled my fancy so much that I burst into a loud fit of laughter, which somewhat startled our flock of visitors; while Jerry, sitting up, hove a stick he had carried all day made fast to his side in among them.  The missile did not, however, make them turn tail; but, instead, they clustered thickly round it, and, as if it had been some impertinent intruder, began pecking at it furiously.  As we could not carry the birds away, with a praiseworthy self-denial we abstained from firing. When, however, we jumped suddenly up and clapped our hands, away they scuttled at a great rate, chattering and quacking louder than ever.  We hoped, however, to reward ourselves for our present self-denial, by returning with all the party to have a shot at them in the evening. After this we walked on for a mile, and had begun to wonder what had become of our companions, and to be a little anxious at having missed them, when we were startled at hearing a loud roar not three hundred yards from us.  It was very different from that of the sea-lion, and we too soon recognised it as the voice of an angry bull.  Again the bull bellowed, and this time several other bulls lent their voices to the terror-inspiring chorus.  We ran to the top of the highest mound near us, and thence we made out five or six bulls, with their tails up in the air, rushing towards us, following one whose voice we first heard.  The spot on which we stood afforded us no protection, for the beasts would have rushed up it in a moment, but a couple of hundred yards on was a rock with steep sides, just rising above the grass; and our only chance of safety was to climb it before the horns of the first bull had reached our backs.  Had he come directly on, as fast as his legs could carry him, this we should have had no chance of doing; but instead of that, he every now and then stuck his sharp ugly-looking horns into the grass, and tossed it above his head, as if to show how he intended to treat us when he caught us.  We rushed on with our eyes fixed on the rock, not venturing to look behind, and expecting every moment to feel his horns at our backs.  We kept a tight hold of our guns, but unfortunately dropped our wallets and the game we had shot.  On we ran and on came the bull; the rock was a dozen yards before us, and he was not much further off in our rear.  We sprang on; Jerry tripped over a lump of decayed grass, but he picked himself up, and, crying to me not to stop, followed me.  The face of the rock was too perpendicular directly in front to allow me to get up it, but a little to the right it was more broken.  I sprang towards the place, and scrambled up.  Jerry reached the foot of the rock; the bull was making for the right side, where he had seen me climb up.  In another moment he would have pinned Jerry to the rock, or tossed him up to me.
