"Quite a treasure, Grant, here to-night. See, it is radiumized."

He snapped off his torch. In the darkness the little bars glowed irridescent.

"To-morrow I will divide with our Nareda government. One-third for them. And my own share I will export: to Great New York, this shipment. Already I have the order for it."

He added calmly, "The duty is high, Grant. Too bad your big New York market is protected by so large a duty. With my cost of production—these accursed Lowland workmen who demand so much for their labor, and a third of all I produce taken by Nareda—there is not much in it for me."

He had re-lighted the room. I could feel his eyes on me, but I said nothing. It was obvious to me now that he knew I was a government customs agent.

I said, "This certainly interests me, friend Spawn. I'll tell you why some other time."

We exchanged significant glances, both of us smiling.

"Well can I guess it, young Grant. So here is my treasure. Without the duty I would soon be wealthy. Chut! Why should I roll in a pity for myself? There is a duty and I am an honest man, so I pay it."

I said, "Aren't you afraid to leave this stored here?" I knew that this pile of ingots—the quicksilver in its radiumized form—was worth four or five hundred thousand dollars in American gold-coin at the very least.
