“I like him all the better,” said Arthur.

“Well, he’s great fun, I can tell you,” said Tom, throwing himself back on the sofa, and chuckling at the remembrance.  “We had such a game with him one day last half.  He had been kicking up horrid stinks for some time in his study, till I suppose some fellow told Mary, and she told the Doctor.  Anyhow, one day a little before dinner, when he came down from the library, the Doctor, instead of going home, came striding into the hall.  East and I and five or six other fellows were at the fire, and preciously we stared, for he don’t come in like that once a year, unless it is a wet day and there’s a fight in the hall.  ‘East,’ says he, ’just come and show me Martin’s study.’  ‘Oh, here’s a game,’ whispered the rest of us; and we all cut upstairs after the Doctor, East leading.  As we got into the New Row, which was hardly wide enough to hold the Doctor and his gown, click, click, click, we heard in the old Madman’s den.  Then that stopped all of a sudden, and the bolts went to like fun.  The Madman knew East’s step, and thought there was going to be a siege.

“‘It’s the Doctor, Martin.  He’s here and wants to see you,’ sings out East.

“Then the bolts went back slowly, and the door opened, and there was the old Madman standing, looking precious scared—­his jacket off, his shirt-sleeves up to his elbows, and his long skinny arms all covered with anchors and arrows and letters, tattooed in with gunpowder like a sailor-boy’s, and a stink fit to knock you down coming out.  ’Twas all the Doctor could do to stand his ground, and East and I, who were looking in under his arms, held our noses tight.  The old magpie was standing on the window-sill, all his feathers drooping, and looking disgusted and half-poisoned.

“‘What can you be about, Martin?’ says the Doctor.  ’You really mustn’t go on in this way; you’re a nuisance to the whole passage.’

“’Please, sir, I was only mixing up this powder; there isn’t any harm in it.  And the Madman seized nervously on his pestle and mortar, to show the Doctor the harmlessness of his pursuits, and went on pounding—­click, click, click.  He hadn’t given six clicks before, puff! up went the whole into a great blaze, away went the pestle and mortar across the study, and back we tumbled into the passage.  The magpie fluttered down into the court, swearing, and the Madman danced out, howling, with his fingers in his mouth.  The Doctor caught hold of him, and called to us to fetch some water.  ‘There, you silly fellow,’ said he, quite pleased, though, to find he wasn’t much hurt, ’you see you don’t know the least what you’re doing with all these things; and now, mind, you must give up practising chemistry by yourself.’  Then he took hold of his arm and looked at it, and I saw he had to bite his lip, and his eyes twinkled; but he said, quite grave, ’Here, you see, you’ve been making all these foolish marks on yourself, which you can never get out, and you’ll be very sorry
