Among the changes of opinion which had by degrees crushed down Mr. Armstrong's prejudices and crotchets, were two important ones, not perhaps in themselves, but in their results. He took a house for his family at Kilburn, which was then a really rural suburb of London. Sometimes he would ride into town to his business, or take the newly established omnibus which left that locality in time for business hours. This arrangement led to the less important change from an early to a late dinner, and also to the choice of a school for his youngest boy, Freddy, now in his eighth year. The child's health had always suffered in London, and as, since their residence in the country, he appeared so much better, Mrs Armstrong wished him to remain at home and go daily to a school in the neighbourhood. It was not long before a circular found its way from Englefield Grange School to Lime Grove, as Mr. Armstrong's residence was named, from two magnificent lime-trees which stood as sentinels on each side the entrance gate, in summer filling the air with their sweet fragrance. Mrs. Armstrong decided to call upon the principal, Dr. Halford, herself, and with all a mother's anxiety talk to him about her boy. Her own health had wonderfully improved during the six months of her residence at Kilburn. The open country--for houses then were few and far between--the sweet fresh air, the pleasant walks, gave her, as it were, new life, and last, but not least, the six o'clock dinner suited her better than a late supper. Mr. Armstrong would sometimes tell her she was growing young again, and it may be understood well how her relatives rejoiced over the change in her husband's opinions which had brought about such pleasant results. This improved state of health enabled Mrs. Armstrong to array herself fearlessly in warm winter clothing, and venture out in the cold frosty air a few weeks after Christmas, to call upon Dr. Halford. The distance along the country road was very trifling, and she had more than once noticed the large old-fashioned house which stood back from the road, surrounded by playgrounds, orchards, and a farmyard, all visible to the passer-by. The vacation was nearly at an end, and the house, with its large dormitories and schoolrooms, in perfect readiness for the return of Dr. Halford's pupils. Its clean and well-furnished appearance satisfied the rather fastidious lady, although she had no intention of sending her boy as a boarder. She had been conducted to a pleasant drawing-room overlooking a beautiful prospect at the back of the house, and instead of taking the chair placed for her she advanced to the window to admire the view. While thus standing, she almost started as the door opened and the doctor entered.
