"But you know, Bessy, I'm very stupid, and my head aches so to-night!"

"Well! the air will do it good. Really, Mary, I would go myself, only I'm so busy; and you know Bill is too careless, mother says, to fetch Jenny through the streets; and besides they would quarrel, and you can always manage Jenny."

Mary sighed, and went away to bring her sister home. Bessy sat down to her knitting. Presently Bill came up to her with some question about his lesson. She told him the answer without looking at the book; it was all wrong, and made nonsense; but Bill did not care to understand what he learnt, and went on saying, "Twelve inches make one shilling," as contentedly as if it were right.

Mary brought Jenny home quite safely. Indeed, Mary always did succeed in everything, except learning her lessons well; and sometimes, if the teacher could have known how many tasks fell upon the willing, gentle girl at home, she would not have thought that poor Mary was slow or a dunce; and such thoughts would come into the teacher's mind sometimes, although she fully appreciated Mary's sweetness and humility of disposition.

To-night she tried hard at her tables, and all to no use. Her head ached so, she could not remember them, do what she would. She longed to go to her mother, whose cool hands around her forehead always seemed to do her so much good, and whose soft, loving words were such a help to her when she had to bear pain. She had arranged so many plans for to-night, and now all were deranged by Bessy's new fancy for knitting. But Mary did not see this in the plain, clear light in which I have put it before you. She only was sorry that she could not make haste with her lessons, as she had promised Jenny, who was now upbraiding her with the non-fulfilment of her words. Jenny was still up when Tom and Jem came in. They spoke sharply to Bessy for not having their porridge ready; and while she was defending herself, Mary, even at the risk of imperfect lessons, began to prepare the supper for her brothers. She did it all so quietly, that, almost before they were aware, it was ready for them; and Bessy, suddenly ashamed of herself, and touched by Mary's quiet helpfulness, bent down and kissed her, as once more she settled to the never-ending difficulty of her lesson.

Mary threw her arms round Bessy's neck, and began to cry, for this little mark of affection went to her heart; she had been so longing for a word or a sign of love in her suffering.

"Come, Molly," said Jem, "don't cry like a baby;" but he spoke very kindly. "What's the matter? the old headache come back? Never mind. Go to bed, and it will be better in the morning."

"But I can't go to bed. I don't know my lesson!" Mary looked happier, though the tears were in her eyes.

"I know mine," said Bill, triumphantly.

"Come here," said Jem. "There! I've time enough to whittle away at this before mother comes back. Now let's see this difficult lesson."
