"Oh, perfectly!" the latter answered. "The dear child was all interest and endeavour."

Lady Adeline said no more; but such docility was unnatural, and she did not like the look of it at all.

Next day Angelica, with an innocent air, gave Miss Apsley a long division sum which she had completed during the night. It was done by an immense number of figures, and covered four sheets of foolscap gummed together. Miss Apsley worked at it for an hour to verify it, and, finding it quite correct, she decided that Angelica knew long division enough, and must go on to something else. Her first impression was that she had secured a singularly apt pupil, and she was much surprised, when she began to teach Angelica the next rule in arithmetic, to find that she could not make the dear child see it. Angelica listened, and tried, with every appearance of honest intention, getting red and hot with the effort; and she would not put the slate down; she would go on trying till her head ached, she was so eager to learn; but work as she might, she could do nothing but long division. Miss Apsley said she had never known anything so singular. Lady Adeline sighed.

For about a week, the twins "lay low."

The tutor had found it absolutely impossible to teach Diavolo anything. The boy was perfectly docile. He would sit with his bright eyes riveted on his master's face, listening with might and main apparently; but at the end of every explanation the tutor found the same thing. Diavolo never had the faintest idea of what he had been talking about.

At the end of a week, however, the children changed their tactics. When lessons ought to have begun one morning Diavolo went to Miss Apsley, and sat himself down beside her in Angelica's place, with a smiling countenance and without a word of explanation; while Angelica presented herself to the tutor with all Diavolo's books under her arm.

"Please, sir," she said, "there must have been some mistake. Diavolo and I find that we were mixed somehow wrong, and I got his mind and he got mine. I can do his lessons quite easily, but I can't do my own; and he can do mine, but he can't do these"—holding up the books. "It's like this, you see. I can't learn from a lady, and he can't learn from a man. So I'm going to be your pupil, and he's going to be Miss Apsley's. You don't understand twins, I expect. It's always awkward about them; there's so often something wrong. With us, you know, the fact of the matter is that I am Diavolo and he is me."

The tutor and governess appealed to Mr. Hamilton-Wells, and Mr. Hamilton-Wells sent for the twins and lectured them, Lady Adeline sitting by, seriously perplexed. The children stood to attention together, and listened respectfully; and then went back to their lessons with undeviating cheerfulness; but Diavolo did Angelica's, and Angelica did his diligently, and none other would they do.

But this state of things could not continue, and in order to end it, Mr. Hamilton-Wells had recourse to a weak expedient which he had more than once successfully employed unknown to Lady Adeline. He sent for the twins, and consulted their wishes privately.

"What do you want?" he asked.
