The few days demanded by the young physician were soon over. Resting in the powerful arms of her father, with Molly standing pale and trembling by her side, Kitty awaited the eventful operation.

"You need not be afraid, my little angel," said the doctor, consolingly; "I will not hurt you much."

"Oh! even if it should hurt me very much," answered the gentle child, "what pain could possibly equal the bliss which I expect to receive from your skilful hands? To see my father, and my Molly,—my Molly!—how long have I yearned with a sick heart to see my Molly!"

The physician raised his hand,—touched the darkened eyeballs. A loud shriek of joy,—another and another,—announced the complete success of the delicate operation. But Kitty was forced to conquer her wild longing to gaze on the faces she loved; for after a single fleeting second, the physician carefully bound a thick band of linen round her head, that the tender organs might become gradually accustomed to the light and air.

No pen could describe her rapture, when, after the removal of the veiling band, she lay for the first time with the full power of sight in the arms of her loved ones! Tenderly and lovingly, she embraced them again and again; now she gazed into the joy-raying eyes of her happy father,—now into the deep, blue, tender eyes of the beloved Molly,—as if to make up, in the fulness of her bliss, for the long time she had been deprived of this source of delight. Then she suddenly turned round to the young physician who was standing behind her, and who had been deeply touched by this exciting scene.

"How shall I thank you?" she cried, pressing his hand to her innocent lips, which he vainly struggled to withdraw. "O, let me kiss your hand," she softly prayed, "let me kiss the dear hand which has enabled me to see my father and my Molly; and tell us how we can make you happy! We can offer you no fitting reward; for what price would be sufficient to pay you for the benefit you have conferred upon us? Only some pledge of our eternal gratitude, some sign of undying remembrance from the family whom you have made so blessed, ought we to give you!"

The young man bent down to hide his tears, kissed the grateful child, and murmured lightly: "Your joy, Kitty, which has rendered this hour the happiest of my whole life, and whose remembrance will always be dear to my heart, has already been to me a high and holy reward! But," he continued, in a voice scarcely audible, and broken by emotion, "there is a still higher, a still dearer reward, which I would willingly owe to your prayers for me, Kitty! Ask your dear father to receive me as his son! Ask the beloved sister if she will trust the happiness of her life in my hands! Kitty, plead for me!"

He could say no more; he was choked by his emotions. But Molly had understood his broken words; covered with blushes, she flew to her father, who took her by the unresisting hand, and tenderly led her to the young physician.

"You have, indeed, chosen the most precious reward," said O'Neil, "yet I willingly give it to you, for you seem to me to be a man of noble character. The manner in which you practise your benevolent art is the surest proof to me of your kind heart!"
