Selfishly dear as she had long been to Lady Bertram, she could not be parted with willingly by her. No happiness of son or niece could make her wish the marriage. But it was possible to part with her, because Susan remained to supply her place. Susan became the stationary niece, delighted to be so; and equally well adapted for it by a readiness of mind, and an inclination for usefulness, as Fanny had been by sweetness of temper, and strong feelings of gratitude. Susan could never be spared. First as a comfort to Fanny, then as an auxiliary, and last as her substitute, she was established at Mansfield, with every appearance of equal permanency. Her more fearless disposition and happier nerves made everything easy to her there. With quickness in understanding the tempers of those she had to deal with, and no natural timidity to restrain any consequent wishes, she was soon welcome and useful to all; and after Fanny's removal succeeded so naturally to her influence over the hourly comfort of her aunt, as gradually to become, perhaps, the most beloved of the two. In her usefulness, in Fanny's excellence, in William's continued good conduct and rising fame, and in the general well-doing and success of the other members of the family, all assisting to advance each other, and doing credit to his countenance and aid, Sir Thomas saw repeated, and for ever repeated, reason to rejoice in what he had done for them all, and acknowledge the advantages of early hardship and discipline, and the consciousness of being born to struggle and endure.
