And of course because he lived in an age when the Three Rs were more important than Free Milk. They made him literate and left the rest to him. He lived on white-flour scones and stewed tea and died hale and hearty at the age of ninety-two.

She was roused from her musings by Miss Rouse. There was a new expression on Miss Rouse's face, and Lucy didn't like the new expression at all. She had seen Miss Rouse look despairing, smarmy, smug, and worried, but till now she had never seen her look furtive.

Why should she be looking furtive?

She watched her for a moment or two, curiously.

Rouse looked up and caught her gaze and looked quickly away again. Her furtive expression had gone; what had taken its place was one labelled Consciously Carefree. Lucy knew all about that expression. She had not been Form Mistress of the Lower Fourth for nothing. Every eater of illicit sweets wore that expression. So did those who were doing their arithmetic in French lesson.

So did those who were cheating at an examination.

What was it Henrietta had said? "She finds written work difficult."

So.

Emphysema and all those flowery sounding things were too much for Miss Rouse, and so she had provided some aids to memory. The question was what kind of aids and where were they? Not on her knee. The desks were open in front, so that a lap was no safe billet for a crib. And one could hardly write enough pathology on one's finger-nails to be of much help; fingernails were useful only for formula. The obvious solution would be the notes up the sleeve, with or without an arrangement of elastic, but these girls had no sleeves below the elbow. Then, what? Where? Or was it that she was just having glimpses of O'Donnell's paper in front of her? Or Thomas's to her right?

Lucy went back to her letters for a moment or two, and waited. All schoolmistresses know this gambit. She looked up casually at the Seniors in general and again went back to her letters. When next she looked up it was straight at Rouse. Rouse's head was low over her paper and in her left hand she held a handkerchief. Now even on a handkerchief it is not possible to write anything that is helpful on so large a subject as pathology, nor is it an easy affair to manipulate; on the other hand handkerchiefs were not common objects at Leys, and certainly no one else was clutching one and dabbing a nose occasionally with it. Lucy decided that whatever sources of information Rouse had lay in her left hand. Her desk was at the back on the window side, so that the wall was to her left; whatever she did with her left hand was not overlooked by anyone.
