"Oh, it's quite right, gentlemen; fishes have their fancies and likings for a tasty bit, same as crocodiles has. I arn't sailed all round the world without picking up a few odds and ends to pack up in my knowledge-box. Why, look at sharks. They don't care for nigger; it's too plentiful. But let them catch sight of a leg or a wing of a nice smart white sailor, they're after it directly. Them crocs too! Only think of a big ugly lizardy-looking creetur boxed up in a skin half rhinoceros, half cow-horn--just fancy him having his fads and fancies! Do you know what the crocodile as lives in the river Nile thinks is the choicest tit-bit he can get hold of?" "Not I," said Poole. "Giraffe perhaps." "No, sir; what he says is dog, and if he only hears a dog running along the bank yelping and snapping and chy-iking, he's after him directly, finishes him up, and then goes and lies down in the hot sun with his mouth wide open, and goes to sleep. Ah, you may laugh, sir; but I've been up there in one of them barges as they calls darbyers, though how they got hold of such an Irish name as that I don't know. It was along with a orficer as went up there shooting crocs and pottomhouses. Oh, I've seen the crocs there often--lots of them. Do you know what they opens their mouths for when they goes to sleep, Mr Burnett, sir?" "To yawn, I suppose," said Fitz. "Haul away there, my lad! Look alive!" came in a deep growl from below; and Chips winked and made the great muscles stand out in his brown arms as he hauled, but kept on talking all the same. "Yawn, sir! Nay, that isn't it. It's a curiosity in nat'ral history, and this 'ere's fact. You young gents may believe it or not, just as you like." "Thank you," said Fitz dryly; "I'll take my choice." "Ah, I expect you won't believe it, sir. But this 'ere's what it's for. He leaves his front-door wide open like that, and there's a little bird with a long beak as has been waiting comes along, hippity-hop, and settles on the top of Mr Croc's head, and looks at first one eye and then at the other to see if he's really asleep, and that there is no gammon. He aren't a-going to run no risks, knowing as he does that a croc's about one of the artfullest beggars as ever lived. I suppose that's why they calls 'em amphibious. Oh, they're rum 'uns, they are! They can sham being dead, and make theirselves look like logs of wood with the rough bark on, and play at being in great trouble and cry, so as to get people to come nigh them to help, and then snip, snap, they has 'em by the leg, takes them under water to drown, and then goes and puts 'em away in the cupboard under the bank." "What for?" said Poole.
