Henderson had ordered that the costumes be kept a great secret. Through a Los Angeles firm he provided dominoes for the five committeemen. But there were half a dozen other dominoes at the ball, so the committee quickly lost its identity. Oscar Ames came as a hobo. Henderson had a policeman's uniform, while the two cub engineers wore, one, a cowboy outfit; the other, an Indian chief's. Mrs. Henderson was dressed as a squaw.

Penelope wore a flower girl's costume, improvised from the remains of the chintz she had brought from New York. Jim viewed her with great complaisance. No one could look like Pen, he thought, and he would dance with her all the evening. Jim went as a monk. To his chagrin, when they reached the hall he found that Pen had made Mrs. Ames a costume exactly like her own, and with the complete face masks they wore, they might have been twins. They were just of a height and Mrs. Ames danced well. The children and the phonograph had long ago attended to that.

There was nothing stupid about the ball from the very start. The policeman ended the grand march by arresting the hobo, who put up a fight that included two of the dominoes. The orchestra swung into "La Paloma" and in a moment the hall was full of swaying colors, drifting through the golden desert dust that filled the room. There were twice as many men at the ball as women. The latter were popular to the point of utter exhaustion.

Henderson looked over the tallest domino, seized him by the throat and with wild flourishes of his club, backed him into a corner.

"Say, Boss Still Jim," he whispered, "that old nut of a chairman doesn't look as if he had anything but skim milk in his veins. But do you sabez he's danced three times with that little fat ballet girl and he's hugging the daylights out of her. He'd ought to be investigated."

The tall domino looked at the couple indicated. "I'll start investigating, myself," he whispered.

"Wish I could get a dance with her, but I can't," said Henderson. "My Missis knows who I am. I ain't got her spotted yet, though. Yes, I have. That flower girl's her. I'd know the way she jerks her shoulders anywhere."

He cut neatly in and separated the flower girl from the monk. "Look here, Minnie," he said gently. "You ain't called on to dance like a broncho, you know. Remember, you're the mother of a family! Cut out having too many dances with that monk. He holds you too tight. I think he's one of the committee men. You floss up to the tallest domino and give him a good time. That's the Boss."

The flower girl sniggered and Henderson pushed her from him with marital impatience and took an Indian squaw away from the hobo.
