"How beastly happy you two look sitting there!" he said wistfully.

"I don't suppose you'd care to change places with poor little us," replied the Duke chaffingly.

"How about poor little me?" said the Angel modestly. "I've got to run about behind the wheels of popularity, like a spotted dog behind a carriage, getting all the dust and trying to look as if I was an important part of the machine. I must seem a perfect fool to you onlookers sometimes."

"I think you are a perfect angel," said the Duke.

The Angel-that-had-been-Quinston smiled and passed on his way, pursued across the breadth of the Horse Guards Parade by a tiresome little sparrow that cheeped incessantly and furiously at him.

"That's only the beginning," said the Duke complacently; "I've made it operative with all of them, irrespective of parties."

Belturbet made no coherent reply; he was engaged in feeling his pulse. The Duke fixed his attention with some interest on a black swan that was swimming with haughty, stiff-necked aloofness amid the crowd of lesser water-fowl that dotted the ornamental water. For all its pride of bearing, something was evidently ruffling and enraging it; in its way it seemed as angry and amazed as the sparrow had been.

At the same moment a human figure came along the pathway. Belturbet looked up apprehensively.

"Kedzon," he whispered briefly.

"An Angel-Kedzon, if I am not mistaken," said the Duke. "Look, he is talking affably to a human being. That settles it."
