"Ow!" exclaimed the captive, with no uncertain voice. "Let go, you ass,you're hurting."The voice was a treble voice. This surprised O'Hara. It looked verymuch as if he had put up the wrong bird. From the dimensions of the armwhich he was holding, his prisoner seemed to be of tender years.

　　"Let go, Harvey, you idiot. I shall kick."Before the threat could be put into execution, O'Hara, who had beenfumbling all this while in his pocket for a match, found one loose, andstruck a light. The features of the owner of the arm--he was stillholding it--were lit up for a moment.

　　"Why, it's young Renford!" he exclaimed. "What are you doing downhere?"Renford, however, continued to pursue the topic of his arm, and theeffect that the vice-like grip of the Irishman had had upon it.

　　"You've nearly broken it," he said, complainingly.

　　"I'm sorry. I mistook you for somebody else. Who's that with you?""It's me," said an ungrammatical voice.

　　"Who's me?""Harvey."At this point a soft yellow light lit up the more immediateneighbourhood. Harvey had brought a bicycle lamp into action.

　　"That's more like it," said Renford. "Look here, O'Hara, you won'tsplit, will you?""I'm not an informer by profession, thanks," said O'Hara.

　　"Oh, I know it's all right, really, but you can't be too careful,because one isn't allowed down here, and there'd be a beastly row if itgot out about our being down here.""And _they_ would be cobbed," put in Harvey.

　　"Who are they?" asked O'Hara.

　　"Ferrets. Like to have a look at them?""_Ferrets!_""Yes. Harvey brought back a couple at the beginning of term. Rippinglittle beasts. We couldn't keep them in the house, as they'd have gotdropped on in a second, so we had to think of somewhere else, andthought why not keep them down here?""Why, indeed?" said O'Hara. "Do ye find they like it?""Oh, _they_ don't mind," said Harvey. "We feed 'em twice a day.

　　Once before breakfast--we take it in turns to get up early--and oncedirectly after school. And on half-holidays and Sundays we take themout on to the downs.""What for?""Why, rabbits, of course. Renford brought back a saloon-pistol withhim. We keep it locked up in a box--don't tell any one.""And what do ye do with the rabbits?""We pot at them as they come out of the holes.""Yes, but when ye hit 'em?""Oh," said Renford, with some reluctance, "we haven't exactly hit anyyet.""We've got jolly near, though, lots of times," said Harvey. "LastSaturday I swear I wasn't more than a quarter of an inch off one ofthem. If it had been a decent-sized rabbit, I should have plugged itmiddle stump; only it was a small one, so I missed. But come and seethem. We keep 'em right at the other end of the place, in case anybodycomes in.""Have you ever seen anybody down here?" asked O'Hara.

　　"Once," said Renford. "Half-a-dozen chaps came down here once while wewere feeding the ferrets. We waited till they'd got well in, then wenipped out quietly. They didn't see us.""Did you see who they were?""No. It was too dark. Here they are. Rummy old crib this, isn't it?

　　Look out for your shins on the chairs. Switch on the light, Harvey.

　　There, aren't they rippers? Quite tame, too. They know us quite well.

　　They know they're going to be fed, too. Hullo, Sir Nigel! This is SirNigel. Out of the 'White Company', you know. Don't let him nip yourfingers. This other one's Sherlock Holmes.""Cats-s-s--s!!" said O'Hara. He had a sort of idea that that was theright thing to say to any animal that could chase and bite.

　　Renford was delighted to be able to show his ferrets off to sodistinguished a visitor.

　　"What were you down here about?" inquired Harvey, when the littleanimals had had their meal, and had retired once more into privatelife.

　　O'Hara had expected this question, but he did not quite know whatanswer to give. Perhaps, on the whole, he thought, it would be best totell them the real reason. If he refused to explain, their curiositywould be roused, which would be fatal. And to give any reason exceptthe true one called for a display of impromptu invention of which hewas not capable. Besides, they would not be likely to give away hissecret while he held this one of theirs connected with the ferrets. Heexplained the situation briefly, and swore them to silence on thesubject.

　　Renford's comment was brief.

　　"By Jove!" he observed.

　　Harvey went more deeply into the question.

　　"What makes you think they meet down here?" he asked.

　　"I saw some fellows cutting out of here last night. And you say ye'veseen them here, too. I don't see what object they could have down hereif they wer............
