“Sure. I’ll tell you. It won’t take long. I made an idiot of myself, to be brief. You know my father is well off, and he makes me a good allowance. One of his rules, though, and one I never broke but once, was never to gamble, and another was never to sign a note. I broke both.

“Last year when I was a Junior I got in with a fast set of fellows. We didn’t do anything very bad, but one night there was a game of chance in one of the rooms. I was urged to play, and, not wanting to be a kill-joy, I foolishly agreed. I knew dad would never forgive me if he found it out, but I didn’t think he would. He had said I would have to leave school, and go to work, if I gambled, or signed a note.

“Well, I lost, as most anyone will if he keeps it up long enough. I lost all my ready money, and I got in debt. I had no way of paying, and the Junior to whom I was indebted suggested that I give him my I. O. U. for the amount. I did, scribbling a promissory note on a piece of paper. The sum was quite large, and I see now what a chump I was. But I expected to be able to pay in time, and the fellow said there was no hurry.

“But when my next allowance came I went out on a lark, and we did some damage that we had to pay for. This took all the cash I had, and I owed more. I dared not ask for additional money, for I did not want to explain to dad how foolish I had been on two occasions. I went to the Junior, told him my predicament, and he kindly offered to wait for his debt, though the note was overdue.

“Then, most unexpectedly, this Junior’s father died, and left him a lot of money. He left school in a hurry to arrange his affairs, and go abroad. The night before he left he wrote me a letter saying he had destroyed the promissory note, and said that I need not pay it, as it was a foolish debt at best.

“That made me happy until all at once the storm broke. Just before the close of school last term Professor Skeel sent for me. He told me he had a note of mine, and demanded payment. I was dumbfounded, and said I didn’t know what he meant.

“He explained that before leaving, this junior, whose name I won’t mention, had sold my promissory note to him, and that as he now owned it I must pay it to him. I said he was mistaken, and told about the letter I had.”

“Why didn’t you show it to him?” asked Tom. “That would have been good evidence.”

“Very foolishly I had destroyed it as soon as I read of my release from the obligation. I did not want a scrap of paper around to remind me of it. So I had no proof, and Skeel only laughed at me. He said he held the note, and he showed it to me hastily, but I thought it was the real thing. He threatened, if I did not pay, to tell dad, and I knew what that meant, for, somehow, Skeel had learned about the game of chance.
