roaching at a rapid walk.

"Begging your pardon, doctor," said the sergeant, "but is that a camera
that the gentleman has, and is he thinking of taking a picture of the
barrack?"

"He is," said the doctor, "but he's not photographing it as a barrack
at all. He's doing it in an entirely different spirit. So there's no
necessity for you to start any theory about his being a German spy, or
to raise stupid objections."

"I wasn't thinking of objecting," said the sergeant. "It makes no matter
to me what notion he has in his head. But what Constable Moriarty was
saying to me this minute----" he hesitated, and then added, "speak up now,
Moriarty."

"What the sergeant said to me," said Moriarty, "as soon as ever he seen

Mr. Billing, standing bare-headed beside his camera, squeezed a yellow

photographs round in these parts, and Constable Moriarty would have been
pleased to be took on account of being able to send the photo after to a
young lady that he is acquainted with up in Dublin."

"There's no young lady up in Dublin," said Moriarty sulkily.

Dr. O'Grady was a man of quick sympathy and a kind heart. He realised
at once that both Sergeant Colgan and Constable Moriarty wanted to have
their photographs taken.

"Go over to the door of the barrack," he said, "and arrange yourselves
in such a way as to look as ornamental as possible. I'll try to get the
gentleman to take another photograph."

Mr. Billing had slipped his dark slide into his pocket, and was
unscrewing his camera from its stand. Dr. O'Grady called to him.

"I'm afraid," he said, "that you got your photogr
