So Harry's attachment to his young master grew stronger and stronger, and all the more so as he came to see through the more attractive but shallower character of Walter, whose praises were being constantly sounded in his ears by Mr Huntingdon.  And there was one thing above all others which tended to deepen his attachment to Amos, which was Amos's treatment of his sister, who was still the darling of Harry's heart.  Walter loved his sister after a fashion.  He could do a generous thing on the impulse of the moment, and would conform himself to her wishes when it was not too much trouble.  But as for denying himself, or putting himself out of the way to please her, it never entered into his head.  Nevertheless, any little attention on his part, spite of his being so much younger than herself, was specially pleasing to Julia, who was never so happy as when she and he could carry out by themselves some little scheme of private amusement.  Harry noticed this, and was far from feeling satisfied, observing to the housekeeper that "Master Walter was a nasty, stuck-up little monkey; and he only wondered how Miss Julia could be so fond of him."  On the other hand, Amos always treated his sister, even from his earliest boyhood, with a courtesy and consideration which showed that she was really precious to him.  And, as she grew up towards womanhood and he towards mature boyhood, the beauty and depth of his respectful and unselfish love made themselves felt by all who could value and understand them, and among these was Harry.  He could appreciate, though he could not explain, the contrast between a mere sentiment of affection, such as that which prompted Walter to occasional acts of kindness to his sister which cost him nothing, and the abiding, deep-seated principle of love in Amos which exhibited itself in a constant thoughtful care and watchfulness to promote the happiness of its object, his beloved sister.
