“Ahem!” said Capt. Steele, clearing his throat, “was that—er—er—strictly professional, Dr. Gaylord?”

“It was strictly humane, Captain. The man was crushed and mangled from the waist down, and according to all the laws of science and common-sense has been as good as dead ever since the accident. He couldn’t have lived until now without the morphine. When that failed to soothe him the end was bound to creep nearer by slow degrees, allowing him to suffer horrible torments. I couldn’t stand that, and he couldn’t. So he begged me to end it for him, and I did.”

“You’re a good man, Gaylord,” remarked Uncle Naboth, mopping his bald head with his red bandanna. “I’m glad you had the courage to do it.”

“This Prince of China,” said the doctor, leaning back in his chair and thrusting his hands in his pockets, “was a royal good fellow. I had observed him on shipboard, and was attracted by his cheerful, intelligent face. When the Karamata Maru broke up I left everyone else to attend to Kai Lun Pu, until I discovered he was fatally injured. Unfortunately all my surgical tools and requirements were out of reach, and in the pockets of the clothes which I grabbed up before I rushed on deck were only a small medicine case and my hypodermic outfit. I assisted Mai Lo, the only one of the Prince’s attendants who survived, to get Kai off the wreck and safe aboard this ship, and at his urgent request I remained with him, since the doctor of the Nagasaki Maru could look after the few survivors of the Karamata Maru who were injured. I am well paid for doing this, but I want to state that the money did not influence me in the least.”

To look at the doctor was evidence of the truth of this statement; so we merely nodded assent.

“As soon as I had him settled in your cabin yonder,” he continued, “I told him that he was dying. Kai accepted the decree like a philosopher and asked me how long I could keep him alive without suffering. It was then that we made our bargain, and I promised he should die comfortably. It seems he had certain family affairs to arrange with Mai Lo, who represents him in his province, and afterward he had several long talks with Sam and the other boys here.”

He paused to look from one to the other of us curiously, and the shrewd glance from beneath his prominent gray eyebrows was rather disconcerting.

“By good luck,” he went on, “the Prince finished his arrangements, whatever they were, before the effect of the morphine wore out. When I went to him a while ago I saw the time had come to fulfil my promise. I asked him if he was ready and he said he was. So, in the parlance of the Chinese, he sleeps with his ancestors.”

In the silence that followed we were all busy with our own thoughts. Finally my father asked:

“Where is Mai Lo?”
