But the Doctor was still scrutinising the little pagan, his eyebrows knotted and uplifted.

“What is your name?” he asked.

“Jean-Marie,” said the lad.

Desprez leaped upon him with one of his sudden flashes of excitement, and felt his head all over from an ethnological point of view.

“Celtic, Celtic!” he said.

“Celtic!” cried Madame Tentaillon, who had perhaps confounded the word with hydrocephalous. “Poor lad! is it dangerous?”

“That depends,” returned the Doctor grimly. And then once more addressing the boy: “And what do you do for your living, Jean-Marie?” he inquired.

“I tumble,” was the answer.

“So! Tumble?” repeated Desprez. “Probably healthful. I hazard the guess, Madame Tentaillon, that tumbling is a healthful way of life. And have you never done anything else but tumble?”

“Before I learned that, I used to steal,” answered Jean-Marie gravely.
