“There’s been a leak over at your place and some dirty work over here. The enclosed sheet, which, as I understand it, is supposed to be an explanation of your signals to be used Saturday, has just come into my hands. I’m sending it to you thinking that perhaps you will be able to find the sneak who sent it. We had nothing to do with it here. The fellow who obtained it did so without authorization on his own hook. I’m sorry about it, but I guess the only thing for you to do is to change your signals for the game. Let me know whether this reaches you. I don’t think it has been seen by more than three or four people here, including the fellow who received it, our coach, and myself, and we haven’t made any study of it. Nevertheless, you’d better protect yourself by changing your signals before the game. We’ll look after the fellow at this end, and I hope you’ll find the traitor at your end and give him what he deserves. You fellows can’t say we haven’t always played fair and you mustn’t blame us for this business. I hope we’ll have a good day for the game and a dandy contest.
