"I shall be very happy to come," answered Miss Leicester, and the doctor nodded and went his busy way. Betty was very fond of going to drive with him, and he looked about the neighborhood as he drove along, hoping to catch sight of her; but Betty was at that moment deeply engaged in helping Letty shell some peas for dinner, at the other side of the house, in the garden doorway of the kitchen. She had spent an hour before that with Mrs. Beck, while they tried together with more or less success to trim a new sailor hat for Mary Beck like one of Betty's own. Mrs. Beck was as friendly as possible in these days, but whenever the Fosters were mentioned her face grew dark. She did not like Mrs. Foster; she did not exactly blame her for all that had happened, but she did not pity her either, or feel a true compassion for such a troubled neighbor. Betty never could understand it. At any rate, she had been saved by her unsettled life from taking a great interest in her own or other people's dislikes. That evening, just as the tea-party was in full progress, somebody came for Dr. Prince; and when he returned from his study he announced that he must go at once down the river road to see one of his patients who was worse. Perhaps he saw an eager look in Betty's eyes, for he asked gravely if Miss Leicester had a niece to lend, it being a moonlight evening and not too long a drive. Aunt Barbara made no objection, and our friend went skipping off to the doctor's stable in high glee. "Oh, that's nice!" she exclaimed. "I'm so glad that you're going to take Pepper; she's such a dear little horse." "Pepper is getting old," said the doctor, "but she really likes to go out in the evening. You can see how fast she will scurry home. Get me a whip from the rack, will you, child? I am anxious to be off." Mrs. Prince and Aunt Barbara were busy talking in the parlor, and were taking great pleasure in their social occasion, but Betty was so glad that she need not stay to listen, instead of going down the town street and out among the quiet farms behind brisk old Pepper. The wise, kind doctor at her side was silent as he thought about his patient, yet he felt much pleasure in Betty's companionship. They could smell the new marsh hay and hear the tree-toads; it was a most beautiful summer night. Betty felt very grateful and happy, she did not exactly know why; it was not altogether the effect of Mrs. Prince's tea and cakes, or even because she was driving with the doctor, but the restlessness and uncertainty that make so great a part of a girl's life seemed to have gone away out of her heart. Instead of the excitement there was a pleasant quietness and sense of security, no matter what might be going to happen. Presently the doctor appeared to have thought enough about his patient. "You don't feel chilly, do you?" he asked kindly. "I find it damp and cold, sometimes, after a hot day, crossing this low land."
