The Duke laughed.

"It is Quinston to all outward appearance," he said composedly, "but I fancy you will find, on closer investigation, that it is an angel understudy of the real article."

The Angel-Quinston greeted them with a friendly smile.

"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."

A shabbily dressed lounger had accosted the man who had been Viceroy in the splendid East, and who still reflected in his mien some of the cold dignity of the Himalayan snow-peaks.

"Could you tell me, sir, if them white birds is storks or halbatrosses? I had an argyment—"

The cold dignity thawed at once into genial friendliness.

"Those are pelicans, my dear sir. Are you interested in birds? If you would join me in a bun and a glass of milk at the stall yonder, I could tell you some interesting things about Indian birds. Right oh! Now the hill-mynah, for instance—"

The two men disappeared in the direction of the bun stall, chatting volubly as they went, and shadowed from the other side of the railed enclosure by a black swan, whose temper seemed to have reached the limit of inarticulate rage.

Belturbet gazed in an open-mouthed wonder after the retreating couple, then transferred his attention to the infuriated swan, and finally turned with a look of scared comprehension at his young friend lolling unconcernedly in his chair. There was no longer any room to doubt what was happening. The "silly talk" had been translated into terrifying action.

"I think a prairie oyster on the top of a stiffish brandy-and-soda might save my reason," said Belturbet weakly, as he limped towards his club.
