Jack told him, adding, with a manly air, as he showed the money, 'I can pay you, sir, if fifty dollars is enough.'
'Quite enough,' said the doctor, with a droll smile.
'If it isn't, I'll work for the rest, if you'll trust me. Please save Nanny's eyes, and I'll do any thing to pay you!' cried Jack, getting red and choky in his earnestness.
The doctor stopped smiling, and held out his hand in a grave, respectful way, as he said, 'I'll trust you, my boy. We'll cure Nanny first; and you and I will settle the bill afterward.'
Jack liked that; it was a gentlemanly way of doing things, and he showed his satisfaction by smiling all over his face, and giving the big, white hand a hearty shake with both his rough ones.
The doctor was a busy man; but he kept them some time, for there were no children in the fine house, and it seemed pleasant to have a little girl sit on his knee and a bright boy stand beside his chair; and when, at last, they went away, they looked as if he had given them some magic medicine, which made them forget every trouble they had ever known.
Next day the kind man came to give Nanny her chance. She had no doubt, and very little fear, but looked up at him so confidingly when all was ready, that he stooped down and kissed her softly before he touched her eyes.
'Let Jack hold my hands; then I'll be still, and not mind if it hurts me,' she said. So Jack, pale with anxiety, knelt down before her, and kept the little hands steadily in his all through the minutes that seemed so long to him.
'What do you see, my child?' asked the doctor, when he had done something to both eyes with a quick, skilful hand.
Nanny leaned forward, with the film all gone, and answered, with a little cry of joy, that went to the hearts of those who heard it, 'Jack's face! I see it! oh, I see it!'
