It was rather a trick of Diavolo's "to snail" over his lessons, for in that as in many other things he was very unlike the good little boy who loved his book, besides evincing many other traits of character equally unpopular at the present time. Diavolo would not work unless Angelica made him, and the worst collision with the tutor was upon this subject. "Wake up, Theodore, will you!" Mr. Ellis said, during the first week of their studies. "Not until you call me Diavolo," was the bland response. Mr. Ellis resisted for some time, but Diavolo was firm and would do nothing, and Lady Adeline cautioned the tutor to give in if he saw an opportunity of doing so with dignity. "But the young scamp will be jeeringly triumphant if I do," Mr. Ellis objected. "Oh, no," Lady Adeline answered. "Diavolo prides himself upon being a gentleman, and he says a gentleman never jeers or makes himself unpleasant. His ideas on the latter point, by the way, are peculiarly his own, and you will probably differ from him as to what is or is not unpleasant." Mr. Ellis made a point of calling the boy "Diavolo" in a casual way, as if he had forgotten the dispute, as early as possible after this, and found that Lady Adeline was right. Diavolo showed not the slightest sign of having heard, but he got out his books at once, and did his lessons as if he liked them. Mr. Hamilton-Wells had a habit of always saying a little more than was necessary on some subjects. He was either a born _naturalist_ or had never conquered the problem of what not to say, and he was so incautious as to come into the schoolroom one morning while lessons were going on, and warn Mr. Ellis to be most careful about what he gave the twins to read in Latin, because some of the classic delicacies which boys are expected to swallow without injury to themselves are much too highly seasoned for a young lady; "You must make judicious excerpts," he said. Slap came the dictionary down upon the table, and Angelica was deep in the "ex's" in a moment. Excerpt, she found, was to pick or take out. She passed the dictionary to Diavolo, who studied the definition; but neither of them made a remark. From that day forth, however, they spent every spare moment they had in poring over Latin text-books, until they mastered the language, simply for the purpose of finding out what it was that Angelica ought not to know. There were, as has already been stated, some lively scenes at lessons. "Talk less and do more," Mr. Ellis rashly recommended in the early days of their acquaintance, and after that, when they disagreed, they claimed that they had his authority to settle the difference by tearing each other's hair or scratching each other across the table; and when he interfered, sometimes they scratched him too. Mr. Hamilton-Wells raised his salary eventually.
