Two young men, who had just entered the American Club in Tokio, turned when this hail to one of them was heard.

The hail came from a group in which sat four Americans, one Englishman and three young Japanese. The latter three were in the uniforms of lieutenants of the Emperor’s infantry.

“Come over with me, Dan,” urged Dave in a low voice, as Dalzell held back slightly.

“I wasn’t invited,” murmured Dan.

“You simpleton, that’s because Carter doesn’t know you. I can introduce you, and that will set you straight.”

“How are you, Carter?” asked Dave, as he went straight up to the young man who had hailed him and held out his hand. “I wish to introduce my friend, Mr. Dalzell, same service and same ship.” In turn Dave and Dan were presented to all in the group.

The American naval officers wore blue civilian suits. Carter belonged to the diplomatic service, and was now stationed in Tokio. Dave had first met him in Washington. One of the other Americans was in business in Tokio, and the other two were tourists.

“Mr. Katura was showing us something so wonderful,” Carter explained, “that I asked his permission to call you over to see it. Will you show that wonderful medallion again, Katura?”

The little lieutenant, who appeared to be very shy and diffident, flushed slightly as he bowed. Then, from an inner pocket, he drew out a small lacquer box, from which he took out and passed to Dave a filigree gold plate on which appeared the delicately tinted face of a beautiful Japanese woman.

“I never saw anything so wonderfully exquisite,” gasped Darrin, in genuine admiration. “I didn’t know that such beautiful work could be done.”
