And presently Nan told herself that there was nothing like a good run. She looked to and fro along the river, and listened to the sheep-bell which tinkled lazily in the pasture behind her. She looked over her shoulder to see if a favorite young birch tree had suffered no harm, for it grew close by the straight-edged path in which the cattle came down to drink. So she rested in the old playground, unconscious that she had been following her mother's footsteps, or that fate had again brought her here for a great decision. Years before, the miserable, suffering woman, who had wearily come to this place to end their lives, had turned away that the child might make her own choice between the good and evil things of life. Though Nan told herself that she must make it plain how she could spend her time in Oldfields to good purpose and be of most use at home, and must get a new strength for these duties, a decision suddenly presented itself to her with a force of reason and necessity the old dream of it had never shown. Why should it not be a reality that she studied medicine? The thought entirely possessed her, and the glow of excitement and enthusiasm made her spring from the cedar boughs and laugh aloud. Her whole heart went out to this work, and she wondered why she had ever lost sight of it. She was sure this was the way in which she could find most happiness. God had directed her at last, and though the opening of her sealed orders had been long delayed, the suspense had only made her surer that she must hold fast this unspeakably great motive: something to work for with all her might as long as she lived. People might laugh or object. Nothing should turn her aside, and a new affection for kind and patient Dr. Leslie filled her mind. How eager he had been to help her in all her projects so far, and yet it was asking a great deal that he should favor this; he had never seemed to show any suspicion that she would not live on quietly at home like other girls; but while Nan told herself that she would give up any plan, even this, if he could convince her that it would be wrong, still her former existence seemed like a fog and uncertainty of death, from which she had turned away, this time of her own accord, toward a great light of satisfaction and certain safety and helpfulness. The doctor would know how to help her; if she only could study with him that would be enough; and away she went, hurrying down the river-shore as if she were filled with a new life and happiness.
