Sir Isaac Newton was paying his little yearly call at Grantham; and was seated in a rustic arbor by the side of Mrs. Vincent, now grown gray, and the mother of a goodly brood, well grown up. As they thus sat talking of days agone, his thoughts wandered off upon quadratic equations, and to aid his mind in following the thread, he absent-mindedly lighted his pipe, and smoked in silence. As the tobacco died low, he gazed about for a convenient utensil to use in pushing the ashes down in the bowl of his pipe. Looking down he saw the lady's hand resting upon his knee, and he straightway utilized the forefinger of his vis-a-vis. A suppressed feminine screech followed, but the fires of friendship were not quenched by so slight an incident, which Mrs. Vincent knew grew out of temperament, and not from wrong intent. She lived to be eighty-five, and to the day of her death caressed the scar--the cicatrice of a love-wound. All of which seems to prove that old women can be quite as absurd as young ones--goodness me! * * * * * When Isaac was eighteen, Master Stokes was so well impressed with his star scholar that he called in the young lad's uncle, the Reverend Mr. Ayscough, and insisted that the boy be sent to Cambridge. The uncle being a Cambridge man himself thought this the proper thing to do. On June Fifth, Sixteen Hundred Sixty-one, Isaac presented his credentials from his uncle and Mr. Stokes, and was duly entered in Trinity College as a subsizar, which means that he was admitted on suspicion. A part of the duties of a subsizar was to clean boots, scrub floors and perform various other delightful tasks which everybody else evaded. To be at Trinity College in any capacity was paradise for this boy. He thirsted for knowledge: to know, to do, to perform--these things were his desire. He had been brought up to work, anyway, and to a country boy toil is no punishment. "I knew that if worse came to worst I could get work in the town making furniture and earn a man's wage," he said. In a month he had passed his first examinations and was made a sizar. Before this he had been fag to everybody, but now he was fag to the Seniors only. He not only made their beds and cleaned their rooms, but also worked their examples in mathematics, and thus commanded their respect.
