Until the autumn of this year, life had seemed to flow in one steady, unchanging current. The thought had not entered little Nan Prince's head that changes might be in store for her, for, ever since she could remember, the events of life had followed each other quietly, and except for the differences in every-day work and play, caused by the succession of the seasons, she was not called upon to accommodate herself to new conditions. It was a gentle change at first: as the days grew shorter and the house and cellar were being made ready for winter, her grandmother seemed to have much more to do than usual, and Nan must stay at home to help. She was growing older at any rate; she knew how to help better than she used; she was anxious to show her grandmother how well she could work, and as the river side and the windy pastures grew less hospitable, she did not notice that she was no longer encouraged to go out to play for hours together to amuse herself as best she might, and at any rate keep out of the way. It seemed natural enough now that she should stay in the house, and be entrusted with some regular part of the business of keeping it. For some time Mrs. Thacher had kept but one cow, and early in November, after a good offer for old Brindle had been accepted, it was announced to Nan's surprise that the young cow which was to be Brindle's successor need not be bought until spring; she would be a great care in winter time, and Nan was to bring a quart of milk a day from Jake and Martin's. This did not seem an unpleasant duty while the mild weather lasted; if there came a rainy day, one of the kind neighbors would leave the little pail on his way to the village before the young messenger had started out. Nan could not exactly understand at last why Mrs. Jake and Mrs. Martin always asked about her grandmother every morning with so much interest and curiosity, or why they came oftener and oftener to help with the heavy work. Mrs. Thacher had never before minded her occasional illnesses so much, and some time passed before Nan's inexperienced eyes and fearless young heart understood that the whole atmosphere which overhung the landscape of her life had somehow changed, that another winter approached full of mystery and strangeness and discomfort of mind, and at last a great storm was almost ready to break into the shelter and comfort of her simple life. Poor Nan! She could not think what it all meant. She was asked many a distressing question, and openly pitied, and heard her future discussed, as if her world might come to an end any day. The doctor had visited her grandmother from time to time, but always while she was at school, until vacation came, and poor Mrs. Thacher grew too feeble to enter into even a part of the usual business of the farmhouse.
