At about this time it chanced that Miss Ludington drove into Brooklyn one morning to do some shopping. She was standing at a counter in a large store, examining goods, when she became aware that a lady standing at another counter was attentively regarding her. The lady in question was of about her own height and age, her hair being nearly white, like Miss Ludington's; but it was evident from the hard lines of her face and her almost shabby dress that life had by no means gone so easily with her as with the lady she was regarding so curiously. As Miss Ludington looked up she smiled, and, crossing the store, held out her hand. "Ida Ludington! don't you know me?" Miss Ludington scanned her face a moment, and then, clasping her outstretched hand, exclaimed, delightedly, "Why, Sarah Cobb, where did you come from?" and for the next quarter of an hour the two ladies, quite oblivious of the clerks who were waiting on them, and the customers who were jostling them, stood absorbed in the most animated conversation. They had been school-girls together in Hilton forty-five years before, and, not having met since Miss Ludington's removal from the village, had naturally a great deal to say. "It is thirty years since I have seen any one from Hilton," said Miss Ludington at last, "and I'm not going to let you escape me. You must come out with me to my house and stay overnight, and we will talk old times over. I would not have missed you for anything." Sarah Cobb, who had said that her name was now Mrs. Slater, and that she lived in New York, having removed there from Hilton only a few years previous, seemed nothing loth to accept her friend's invitation, and it was arranged that Miss Ludington should send her carriage to meet her at one of the Brooklyn ferries the day following. Miss Ludington wanted to send the carriage to Mrs. Slater's residence in New York, but the latter said that it would be quite as convenient for her to take it at the ferry. After repeated injunctions not to fail of her appointment, Miss Ludington finally bade her old school-mate good-by and drove home in a state of pleased expectancy. She entertained Paul at the tea-table with an account of her adventure, and gave him an animated history of the Cobb family in general and Sarah in particular. She had known Sarah ever since they both could walk, and during the latter part of their school life they had been inseparable. The scholars had even christened them "The Twins," because they were so much together and looked so much alike. Their secrets were always joint property. The next afternoon Miss Ludington went herself in the carriage to fetch her friend from the ferry. She wanted to be with her and enjoy her surprise when she first saw the restored Hilton on entering the grounds. In this respect her anticipations were fully justified.
