"Do you know of anyone else in school who has a red sweater?"

"No, sir. Gallup has a red and white striped one."

"There wasn't no stripes on the one I saw," said Farmer Mercer decidedly.

"Porter," said the Doctor after a moment's silence. "I'm sorry that I can't bring myself to believe your story. Is there anyone who can substantiate it? Were you alone yesterday afternoon?"

"I'm sorry, sir, that you won't believe me. I wasn't on this man's land yesterday, and I don't think I ever was. Anyhow, I never fished on it. I've never fished since I came here."

"I hope you are telling the truth," answered the Doctor gently. "But circumstantial evidence is sadly against you. There is no one who can prove that you were at the Deep Hole at four o'clock?"

"No, sir, no one knows that I was there at that time." Chub, he reflected, had left him at least a quarter of an hour before and so couldn't have been sure of his whereabouts at four o'clock.

"Hm! That's unfortunate," said the Doctor. He turned to Farmer Mercer. "I don't think I need trouble you to remain, sir. I regret deeply that this has occurred and assure you that punishment will be justly meted out to the culprit."

The farmer arose.

"It's got to be stopped, Doctor," he said. "As for the culprit you've got him right here. That's the boy without a doubt. Put him in his red sweater and I'll tell you mighty quick. Just about his height he was, and kinder slimmish like. Well, you know you own business best. Good morning, Doctor."
