The division of gratifying sensations ought not, in strict justice, to have been equal; for Sir Thomas was fully resolved to be the real and consistent patron of the selected child, and Mrs. Norris had not the least intention of being at any expense whatever in her maintenance. As far as walking, talking, and contriving reached, she was thoroughly benevolent, and nobody knew better how to dictate liberality to others; but her love of money was equal to her love of directing, and she knew quite as well how to save her own as to spend that of her friends. Having married on a narrower income than she had been used to look forward to, she had, from the first, fancied a very strict line of economy necessary; and what was begun as a matter of prudence, soon grew into a matter of choice, as an object of that needful solicitude, which there were no children to supply. Had there been a family to provide for, Mrs. Norris might never have saved her money; but having no care of that kind, there was nothing to impede her frugality, or lessen the comfort of making a yearly addition to an income which they had never lived up to. Under this infatuating principle, counteracted by no real affection for her sister, it was impossible for her to aim at more than the credit of projecting and arranging so expensive a charity; though perhaps she might so little know herself, as to walk home to the Parsonage after this conversation, in the happy belief of being the most liberal-minded sister and aunt in the world.
