"Don't do anything with them; let them do something with you. Shut your eyes and listen to the music; let it get into your bones, and the first thing you know you will be doing it."

With British solemnity Percival closed his eyes and tried to feel the music. Suddenly he was aware that he was moving in rhythm to the insistent beat of the drum.

"That's it!" cried Bobby, excitedly. "You are doing the Grape-Vine; let yourself go. That's it!"

So intent was he upon keeping out of time instead of in it, that he was guided from the loggia into the ball-room before he knew it. His awakening came when a firm hand was laid upon his shoulder. He stopped indignantly. The ship's doctor had not only arrested the development of his new-found talent, but was actually dancing off with his partner!

"Most unwarrantable impertinence!" he stormed to the Scotchman, whom he joined at the door. "Clapped me on the shoulder quite as if I had been under suspicion for felony. Almost expected to hear him say, 'My man, you're wanted.' I shall demand satisfaction of the cub the instant the dance is over."

The Scotchman laughed. "He meant ye no harm. It's a trick they have in the States of changing partners. Watch the game; ye'll see."

"And I can take any man's partner away by simply laying my hand on his shoulder?"

This changed the complexion of things considerably. The Honorable Percival spent the remainder of the evening laying his hand upon the shoulder of whosoever claimed Bobby for a dance.

It was remarkable with what facility he acquired the new steps. He knew that he had a good figure and that he carried it with distinction. The admiring glances that followed his entrance into any public assembly made him pleasantly aware of the fact. To-night, however, if any of his thoughts turned upon himself, they were but stragglers from the main army that marched in solid file under Bobby's banner.

During the intervals when he could not dance with her he retired to the loggia, and thought about her. She was not only the most beautiful creature he had ever seen, but the most adorably responsive. He likened her poetically to an Æolian harp and himself to the wind.
