She said: "I have been spending the morning with a friend, who is half mad with melancholia. She has had a terrible experience. She is a Philadelphia woman. Her husband was a manufacturer of window glass. He died about five years ago from typhoid fever and left her with a small fortune and two daughters; one fourteen years old, one seventeen--nice, rosy, wholesome, well brought up girls. They had always wanted to travel, but during her husband's lifetime he was too busy and she would never leave him. About a year after his death, they concluded, as the lease of their house had run out, to store their furniture and go abroad for a time, with the idea that the girls could perfect themselves in languages and music and see something of the world. I don't want you to think there was anything sensational about them. They were just quiet, middle-class Philadelphians,--you know the type,--modest, conventional, devoted to the proprieties. That's what makes their story all the more tragic. They arrived in London; took quiet lodgings in Dover Street, and concluded to spend six months in England, seeing the sights, and making these London lodgings their headquarters. They had been there all through the month of May, doing picture galleries, churches, and the museums, and occasionally a theatre. One Saturday they had tickets for a concert, and as the place was near and the day was fine, they decided to walk to the place where the concert was to be given, stopping at a shop in Regent street on the way to give an order about something being made there. I don't know what it was, or where the shop was situated, but at all events the three were walking abreast, the girls chattering and joking about the order. The sidewalk was very crowded, so that the mother stepped ahead, but heard her daughters' voices at her elbow for several minutes. The street grew clearer as she went, and she turned to beckon the girls alongside again. She didn't see them, and stood a few moments for them to catch up. After waiting awhile she walked back and still missed them. It occurred to her that they might have passed ahead without her noticing it, and gone on to the shop where they had planned to stop, so she went there and waited twenty minutes. Then she imagined they might have missed their way, and gone to the concert hall to wait for her. By this time she felt sufficient anxiety to hail a cab, but no one had seen them at the concert hall, and she herself had all three of the tickets, so she returned to their lodgings, sure that they would turn up there eventually in any case. At six o'clock they were still absent, and really frightened by this time she visited all the near-by police stations, but could get no news of them.
