These happy days were to end soon, however; and it was by the Lady Castlewood's own decree that they were brought to a conclusion. It happened about Christmas-time, Harry Esmond being now past sixteen years of age, that his old comrade, adversary, and friend, Tom Tusher, returned from his school in London, a fair, well-grown, and sturdy lad, who was about to enter college, with an exhibition from his school, and a prospect of after promotion in the church. Tom Tusher's talk was of nothing but Cambridge now; and the boys, who were good friends, examined each other eagerly about their progress in books. Tom had learned some Greek and Hebrew, besides Latin, in which he was pretty well skilled, and also had given himself to mathematical studies under his father's guidance, who was a proficient in those sciences, of which Esmond knew nothing; nor could he write Latin so well as Tom, though he could talk it better, having been taught by his dear friend the Jesuit Father, for whose memory the lad ever retained the warmest affection, reading his books, keeping his swords clean in the little crypt where the Father had shown them to Esmond on the night of his visit; and often of a night sitting in the chaplain's room, which he inhabited, over his books, his verses, and rubbish, with which the lad occupied himself, he would look up at the window, thinking he wished it might open and let in the good Father. He had come and passed away like a dream; but for the swords and books Harry might almost think the Father was an imagination of his mind--and for two letters which had come to him, one from abroad, full of advice and affection, another soon after he had been confirmed by the Bishop of Hexton, in which Father Holt deplored his falling away. But Harry Esmond felt so confident now of his being in the right, and of his own powers as a casuist, that he thought he was able to face the Father himself in argument, and possibly convert him. To work upon the faith of her young pupil, Esmond's kind mistress sent to the library of her father the Dean, who had been distinguished in the disputes of the late king's reign; and, an old soldier now, had hung up his weapons of controversy. These he took down from his shelves willingly for young Esmond, whom he benefited by his own personal advice and instruction. It did not require much persuasion to induce the boy to worship with his beloved mistress. And the good old nonjuring Dean flattered himself with a conversion which, in truth, was owing to a much gentler and fairer persuader.
