These two were silent. What was passing before their minds? The long summer nights in the far northern seas, with the glory dying in the west; or the moonlight walks on the white deck, with the red star of Ushinish lighthouse burning in the south; or the snug saloon below, with its cards, and candles, and laughter, and Mary Avon singing to herself the song of Ulva? She sang no song of Ulva now.

"Mary and I are very intimate friends," says the other deliberately. "I will say nothing against her. Girls have curious fancies about such things sometimes. But I must admit—for you are my friend too—that I am not surprised you should have been encouraged by her manner to you at one time, or that you should wonder a little at the change."

But even this mild possibility of Mary Avon's being in the wrong she feels to be incompatible with her customary championship of her friend; and so she instantly says—

"Mind, I am certain of this—that whatever Mary does, she believes to be right. Her notion of duty is extraordinarily sensitive and firm. Once she has put anything before her as the proper thing to be done, she goes straight at it; and nothing will turn her aside. And although there is something about it I can't quite understand, how am I to interfere? Interference never does any good. Why do not you ask her yourself?"

"I mean to do so, when I get the chance," said he, simply. "I merely wished to tell you that, if her answer is 'No,' it will be better for me to leave you. Already I fancy my being on board the yacht is a trouble to her. I will not be a trouble to her. I can go. If it is a misfortune, there is no one to blame."

"But if she says 'Yes!'" cried his friend; and there was a wonderful joy in her eyes, and in her excess of sympathy she caught his hand for a moment. "Oh, Angus, if Mary were to promise to be your wife! What a trip we should have then—we should take the White Dove to Stornoway!"

That was her ultimate notion of human happiness—sailing the White Dove up to Stornoway!

"I don't think there is much hope," said he, rather absently, "from her manner of late. But anything is better than suspense. If it is a misfortune, as I say, there is no one to blame. I had not the least notion that she knew Mr. Howard Smith in London."

"Nor did she."

He stared rather.
