As he was passing by the house where Jeff Thatcher lived, he saw a new girl in the garden—a lovely little blue-eyed creature with yellow hair plaited into two long-tails, white summer frock and embroidered pan-talettes. The fresh-crowned hero fell without firing a shot. A certain Amy Lawrence vanished out of his heart and left not even a memory of herself behind. He had thought he loved her to distraction; he had regarded his passion as adoration; and behold it was only a poor little evanescent partiality. He had been months winning her; she had confessed hardly a week ago; he had been the happiest and the proudest boy in the world only seven short days, and here in one instant of time she had gone out of his heart like a casual stranger whose visit is done.
