The doctor groaned.

"Come, Doc," she said, plucking his sleeve, "take a look at Arthur."

The doctor rose uncertainly and paced up and down the floor with his face in his hands, swaying like a drunken man.

"O God!" he moaned, "if I could but bring back his life with mine; but I can't! I can't! I can't!"

Pearl watched him, but said not a word. At last she said:

"Doc, I think Arthur has appendicitis. Come and have a look at him, and see if he hasn't."

With a supreme effort the doctor gained control of himself and made a hasty but thorough examination.

"He has," he said, "a well developed case of it."

Pearl handed him his satchel. "Here, then," she said, "go at him."
