"The common factor—that's what we want, isn't it?"

"Yes," she breathed.

And as they stood, hand in hand, the unspoken thought vibrating between them, the memory came to him of a day long ago when he had stood with another woman—a girl then—before the photographs in the window of the London Stereoscopic Company in Regent Street, and he had scanned faces of successful men. He laughed—he could not help it—and drew his Princess closer to him. Between the analogous then and the wonderful now, how immense a difference! As he laughed she looked swiftly up into his face.

"I know why you laugh."

"No, my Princess. Impossible."

"Mais oui. Tell me. All these great princes"—she swept her little gloved hand toward the frieze. "What is their common factor?"

Paul, forgetful of his mirth, looked round. "'Indomitable will," said he seriously. "Unconquerable ambition, illimitable faith. They all seem to be saying their creed. 'I believe in myself almighty, and in Venice under my control, and in God who made us both, and in the inferiority of the remnant of the habitable globe.' Or else: 'In the beginning God created Venice. Then He created the rest of the world. Then He created Me. Then He retired and left me to deal with the situation.' Or else: 'I am an earthly Trinity. I am myself. I am Venice. I am God.'"

"It is magnificent!" she cried. "How you understand them! How you understand the true aristocratic spirit! They are all, what you call, leaders of men. I did not expect an analysis so swift and so true. But, Paul"—her voice sank adorably—"all these men lack something—something that you have. And that is why I thought you laughed."

He smiled down on her. "Do you think I was measuring myself with these men?"

"Naturally. Why should you not?" she asked proudly.
