'Are you sorry you are not at sea now? Is it that which makes you look so unhappy sometimes?'

'It is, and it isn't; if you can understand what I mean.'

'No, I can't. You have such a dear mother, and such a nice home; why do you want to leave them?'

'I don't want to leave them, even if I could,' said Jack, sadly. 'But there are other things one can't tell little ladies about.'

Such a look of pain and sorrow crossed his face as he spoke, that Estelle instinctively turned away her eyes. She began taking up handfuls of sand to let it run through her fingers.

'Jack,' she remarked, presently, 'I think yours must be a very sad secret, for do you remember how I heard dear Goody crying as she was kneeling? She said, "Jack, my poor boy! Lord, have mercy upon him!" Then, sometimes at night, when she thinks I am asleep, she sighs so heavily, especially when she is saying her prayers.'

On hearing this, Jack suddenly threw himself at full length on the sand, burying his face on his arms. Much startled, Estelle gazed at him in wonder and sympathy. What had upset him so greatly? Why did Goody sigh over him? It was a bewildering puzzle to her, who knew Jack to be the kindest fellow in the world. She could not bear to see him so grieved. It was her fault. Why had she said a word which could hurt him?

'Oh, Jack!' she cried, putting her hand on his shoulder, her voice full of self-reproach, 'I ought not to have told you. I am so sorry! Do forgive me, dear, kind Jack. I wish I could do something for you, Jack—I do wish I could. But for Goody's nursing and care and all your kindness, I should have died.'

'So you would, Missie,' he said, sitting up and drawing the back of his hand across his eyes. He sat for some moments in silence, his eyes on the sands, then rising to his feet, he murmured:' After all, it is a life for a life.'

'What did you say?' asked Estelle, mystified.
