Billy usually stayed to supper three or four times a week, and on the nights when he was not there Norman was at his house. The two boys were inseparable, and a pleasant intimacy had grown up between the families. That night as usual, he went home at nine o'clock, but came running back almost immediately, bareheaded and breathless. His mother had been taken suddenly ill. The only doctor in the place had been called to a case on the other side of the mountain, and nobody knew when he would be home. His father and Sara were nearly scared stiff, they were so frightened, and wouldn't Mrs. Ware please come and tell them what to do? It was the beginning of a long siege, for no nurses were to be had in the little settlement, and there were only the neighbors to turn to in times of stress and trouble. What true neighborliness is, in the fullest meaning of the word, can be known only in pioneer places like this. Hands already full of burdens stretched out to help lighten theirs, and for awhile one common interest and anxiety made the families of Lone-Rock as one. But most of the women who came to offer their services had little children at home, or helpless old people who could not be left long alone, or more work than one pair of hands could manage. The only two of experience, not thus burdened, were Mrs. Ware and old Aunt Sally Doane. So they took turns sitting up at nights, and did all they could on alternate days to relieve poor frightened Sara and her anxious father. Mary, not experienced enough to be left in charge in the sick room, did double duty at home. She did the baking for both families, sometimes three; for many a time old Aunt Sally, too worn out to cook, went home to find a basket full of good things spread out for her and the Captain on the pantry shelves. The Downs family mending went into Mary's basket, and Billy's darns and patches alone were no small matter. Several times a week she slipped over to sweep and dust and do many necessary things that Sara had neither time nor strength to do. Remembering how valiantly the neighbors had served them during Jack's long illness, Mary gladly did her part, and a very large one towards relieving the stricken household. When she saw Mr. Downs' anxious face relax, at some evidence of her thoughtfulness, and heard Sara's tearful thanks poured out in a broken voice, she was glad that fate had kept her in Lone-Rock to play the good angel in this emergency. If she had not been at home, Mrs. Ware could not have been free to take charge of the invalid, and it was her skilful nursing, so the doctor said, which would pull her through the crisis if anything could.
