So I began by relating in full my various interviews with Prince Kai, in the last of which Archie and Joe had been participants. I added that I believed the Prince’s idea of our robbing his ancestors arose from my relation of our former adventures in search of a treasure, which I had told him with a view to amusing him. Once the mischievous notion had seized him, he began to plan ways to assist us, and I think he derived a certain pleasure during his last hours in imagining our difficulties and trying to overcome them. Another thing that doubtless influenced him was the desire to outwit Mai Lo, whom he suspected, probably with good reason, of a desire to rob the tombs himself.

Dr. Gaylord listened to all the story without interruption, and I could see that he was intensely interested. When I finished he smoked for a time in silence, while we watched him rather anxiously. Finally he knocked the ashes from his pipe and said, with decision:

“It looks too pretty to miss, my lads, and if you see where an old fellow like me can be of use to you, I’ll stand by to the last. But I want to warn you that we are taking big chances in this adventure, and if any one of us escapes with a whole skin he’ll be lucky. On the other hand, I know something of the enormous wealth of these ancestral halls, and if we succeed in our undertaking our fortunes will be made. That won’t mean much to you youngsters, of course; but it will enable me to buy a snug farm in England and settle down to end my days in peace. So I’m with you, lads, and you can count on my venturing as much as any of you.”

“Do you know in what part of China the province of Kwang-Kai-Nong is, doctor?” I inquired.

“Surely. It’s away up in the northwest, in the foothills of the Himalayas—a most retired and out-of-the-way place; and that’s what’s going to make our task doubly hard.”

“How can we get there?” asked Archie.

“By starting at Shanghai, traveling up the Yang-tse-Kiang a thousand miles or so to Ichang, and then cutting across country by elephant-train to the edge of the world, which is the province of Kwang-Kai-Nong. That’s not very definite, is it? But the road to Kai-Nong, the capital, is probably well known.”

“Mai Lo will show us the way,” I said.

The doctor looked at me blankly.

“We shall be obliged to take my father and Uncle Naboth into our confidence soon,” I continued, “for the Seagull must make straight for Woosung anchorage, so that we may escort the body of Prince Kai to Shanghai, and up the Yang-tse, while our ship goes to Canton to unload. Then they can pick us up when we return.”
