"A friend of my father's," she answered blushingly. "Roderick Dreghorn, the ivory-hunter."

"I wonder if I might ask you to do something," Li Sin said slowly, "and that is: will you bring your fiancé here some day so that I may congratulate him?"

"I should love to," she said; and she left him, excitedly happy, Li Sin saw; but he also noticed that she seemed a little terrified, a little aghast.

I have told the story of Li Sin to many people, now that he is gone to his own home and is happy there with his poor and his pear-trees, and some of them have believed me because they know China and the manner of man Li Sin is, and some of them have believed me because they know I abhor lies as I abhor the devil. But many cannot understand it. They cannot see why a Manchu duke should become a merchant on Fifth Avenue.

"And if he is as great a doctor as you say—" they object.

There is a passage in Isaiah, I believe, which speaks of Tyre, "whose merchants are princes, whose traffickers are the honorable of the earth." Marco Polo, that ancient Venetian, says of Cathay, that there, of all professions the most esteemed is that of merchant. It is above arms, he says, above learning. And what obtained in the Yellow Empire when Hoang-ti led his people across the desert in the misty dawn of time obtains to-day, from the outer sea to the confines of Mongolia. An ancient and honorable thing it is, a fit profession for princes, a thing pregnant with ideals of honesty and fair dealing, a clean thing. There is nothing anomalous to the eye in Li Sin, a Manchu duke, unearthing the treasures of forgotten days for the New World, and exacting a just profit for the work.

As for the medicine, that was another matter. I could no more imagine Li Sin accepting money for his healing art than I can imagine him stealing alms from a blind beggar. The thing was far too holy for him. There in that glass-topped studio in his house on Fifth Avenue, above the great treasure-store, he studied his science with the enthusiasm of an amateur pursuing a hobby. A queer place it was, with its retorts and vials, its glinting instruments, its Rontgen-ray apparatus, its tubes of deadly serum and of healing drugs. And beside these were the quaint adjuncts of Oriental healing: the twisted tubes of herbs, instruments that seemed like an alchemist's dream, medicines of black, occult art as well as of benevolence, secret, untraceable poisons, liquids which, it is whispered, would bring the dead to life for minutes, which would drive men mad.

Ask the taciturn Lee Fong, on Mott Street, that slant-eyed millionaire. Ask the leaders of the Hip Sing. At the Five Companies of San Francisco, inquire. They will speak of Li Sin as a demigod of medicine.

One has n't to go as far as that to find out. There is a tenement-house on Hudson Street, where the Bracalellos live. There is a romping child there called Beata. For years she was an object of research to physicians in hospitals, because of her twisted spine. Nothing could be done, they decided. They were wrong. Li Sin saw the white-cheeked child carried in the subway on a horrible metal stretcher, strapped to it. It hurt him—the illnesses of children always hurt him. He took charge of her. She romps about now as other children do. There are many cases of that kind.

But above all in my mind there is the tragic case of Mrs. Madge Eaton, who is now happy as a woman farmer on Long Island. Li Sin discovered her creeping up an alleyway to die from hunger, shame, and heartbreak. Against all protestation he took her home. Her story was tragic and very sordid. She had married John Eaton, a man who had come up to Maine for a holiday. He had brought her to New York. In a month he had sent her out to work. She fell ill. Eaton deserted her, taking with him all her jewelry, all her money, all her clothes. When she was discovered, she was sent to a hospital, and when she emerged from there, she found herself without courage to kill herself and without the wherewithal to live. The police sent her to jail two weeks later. When she came out, Li Sin found her, broken, hungry, terrified, wanting to die and yet without courage to face the river.
