They strolled on together, speaking of the buildings they passed, until, opposite the gymnasium, Mr. Detweiler started to leave them, thought better of it and said: "By the way, Byrd, I wonder if I was pledged to secrecy the other day."

"The other day?" repeated Amy questioningly.

"The day I met you and Thayer and--" He looked doubtfully at Chase.

"Bob's all right," Amy reassured him. "I know when you mean, sir. But I don't understand about being pledged--"

"I'll tell you." Mr. Detweiler looked hurriedly at his watch. "I happened to hear from Mr. Daley yesterday that your friend Durkin had got in trouble. You knew that?"

"Yes, sir."

"Well, it seemed that Mr. Fernald thought Durkin had either picked the quarrel or--well, we'll say welcomed it. Daley told me Durkin was on probation and stood a pretty fair chance of losing a scholarship he was after. So, as I hadn't been, as I thought, pledged to secrecy, I told Daley what I knew of the start of the trouble. That seemed to put a different complexion on the matter and Daley went to Mr. Fernald and told him about it. Since then I've wondered whether I ought to have kept my mouth closed. Do you mind?"

"Not a bit," declared Amy heartily. "I'm mighty glad you did tell. I wanted to, but Penny wouldn't hear of it. He said it would be sneaky, or something like that. What--what did Mr. Fernald say, sir?"

"I haven't heard. I hope, though, he will see that your friend Durkin couldn't very well avoid that row on Sunday. It seemed to me rather too bad that he should lose his chance at the scholarship. That is why I 'butted in,' Byrd."

"I'm very glad you did, Mr. Detweiler. I'll find Penny and see if he's heard anything."
