As the girl sat alone later in the evening, she pondered over the words Francis had spoken. That his memory had not failed in any detail within what might be termed the radius of his love story she was well aware. It had been further proved to-day; he had mentioned her singing. Fortunately that presented no difficulty to her, for, although she did not possess a voice in any way remarkable, still, she had been well trained and had sung a good deal in her father's lifetime. He had also spoken of riding, and of her going to Scotland. It might be that he remembered riding with her, and perhaps the first Philippa had arranged a visit to Scotland--she could not tell. But beyond this he had spoken of Bessacre and Bessmoor, giving the places their correct names without hesitating. She had always understood that the names of places presented the gravest difficulty to a memory in any way troubled or imperfect. Did this mean that his mind was perfectly clear upon all that had happened up to the time of the accident, but that from that moment all was darkness? This was frequently so in cases of concussion of the brain, as she knew, but against this explanation was the fact that he had recognised both the doctor and Mrs. Goodman. If he only remembered them as they were at the time of his accident, surely he would have made some comment on their altered appearance. It was this that puzzled--this that made the situation so complex. She made a little plan of campaign in her mind--of books she would read with him, of various little things which she would order which might amuse him. The way bristled with pitfalls if once she allowed herself to consider them. Twenty years! How everything must have altered since then! For instance, how much had the ordinary everyday sights such as pass us every day without our giving them a thought changed in that time! Twenty years ago the motor-car was unknown, electric light was in its infancy. The Heathcotes had cars, but she remembered that Francis' room looked out on a part of the garden and that the drive was not visible from the windows. Therefore, although it was possible that he might have heard the sound of a horn or siren, he would never actually have seen a car. Electric light was installed in his room. She had no idea when this had been done, but he must be quite accustomed to it. It was not until she began to sum them up that she realised how innumerable are the changes wrought by a couple of decades--in our habits, even in our speech. English 'as she is spoke' is a variable quantity, and the jargon of to-day is forgotten to-morrow. Philippa the first had mentioned in one of her letters that she was having "a jolly time." Well, "jolly" as an adjective is as dead as the dodo, and if the letter had been written by her to-day, she, being what she was, would undoubtedly have used the word "ripping."
