Sir Andrew had listened patiently. His had been the grave attitude of a man impressed beyond mere words of agreement or understanding. His reading glasses had been thrust aside. His grey head was inclined towards his clasped hands, and his broad chin found support upon them. His whole poise was of the closest attention. "It's like a--fairy-tale," he said at last as Ruxton's story came to an end, and the deep, calm tones of his voice died out. "Or a--nightmare?" "Ye-es." Sir Andrew swung round in his ample library chair and faced his desk. It was the movement of a man stirred out of his customary calm. Ruxton watched his father closely from his seat on the settle under the mullioned window. He was seeking the effect of his story upon a man whom he knew to be typically British at heart. He had seen it all, had experienced it all. His father had not. Presently Sir Andrew faced him again. "Now your--purpose," he demanded, with the air of crisp business. "You would set out to revolutionize our mercantile marine by the adoption of this--submersible." "As rapidly as is compatible with commercial interests." "You mean that we are to take the entire risk of the success of this new departure?" "It is our contribution to our country's cause." Then Ruxton drew a deep breath.

If it is the success I am sure of, then our gain is twofold. But even if the latter is fulfilled beyond my expectations it is not going to be the easy thing it looks. Listen. Hertzwohl believes that he can completely cover his tracks. I am just as certain that he cannot. Germany will discover the betrayal of her secrets. She will punish the offender in the complete manner of which she is so great a mistress. Then, by every art and wile of which she is capable, by every ruthless persistent purpose for which she is renowned, she will strive to undo the harm already achieved. We shall not be left to peaceful construction, if my understanding of the situation is correct. We may have to face even personal attack upon our lives and upon our ship-yards. It is with ideas of this sort running through my mind that I intend to lay the whole matter before the Cabinet. I intend to secure Government patronage and protection for this scheme. It is the only means by which we can hope to meet the attack which I am convinced will be forthcoming from our country's enemies. It is a lot to ask of you, Dad, at your time of life. Did I not know the great strength of your
