Caroline was his confidante, adviser, secretary, servant, friend. She had a telescope of her own, and when her brother did not need her services she swept the heavens on her own account for maverick comets. In her work she was eminently successful, and five comets at least are placed to her credit on the honor-roll by right of priority. Her discoveries were duly forwarded by her brother to the Royal Society for record. Later, the King of Prussia was to honor her with a gold medal, and several learned societies elected her an honorary member. When Herschel reached the discreet age of fifty he married the worthy Mrs. John Pitt, former wife of a London merchant. It is believed that the marriage was arranged by the King in person, out of his great love for both parties. At any rate Miss Burney thought so. Miss Burney was Keeper of the Royal Wardrobe at the same salary that Herschel had been receiving--two hundred pounds a year. She also took charge of the Court Gossip, with various volunteer assistants. "Gold, as well as stars, glitters for astronomers," said little Miss Burney. "Mrs. Pitt is very rich, meek, quiet, rather pretty and quite unobjectionable." But poor Caroline! It nearly broke her heart. William was her idol--she lived but for him--now she seemed to be replaced. She moved away into a modest cottage of her own, resolved that she would not be an encumbrance to any one. She thought she was going into a decline, and would not live long anyway--she was so pale and slight that Miss Burney said it took two of her to make a shadow. But we get a glimpse of Caroline's energy when we find her writing home explaining how she had just painted her house, inside and out, with her own hands. Things are never so bad as they seem. It was not very long before William was sending for Caroline to come and help him out with his mathematical calculations. Later, when a fine boy baby arrived in the Herschel solar system, Caroline forgave all and came to take care of what she called "the Herschel planetoid." She loved this baby as her own, and all the pent-up motherhood in her nature went out to the little "Sir John Herschel," the knighthood having been conferred on him by Caroline before he was a month old.
