“Try it,” laughed Kendall. “If you hit on anything good I guess Payson will be glad to use it.”

“I suppose the best thing about the number signals is that they can be changed easily. Now I suppose these signals won’t be used in Saturday’s game.”

“Yes, they will. But they’ll be changed for Broadwood.”

“I see.” Cotton absently dropped the sheet of paper in his pocket as he stood up. “Well, I’m going to have another go at it, anyway. I’ll bet I can beat this scheme. I hope I haven’t been in the way. Were you going to do anything?”

“Only grind a little,” replied Kendall. “There’s plenty of time yet. So long, Cotton. Let me know how you get on with that.” He nodded toward the pocket in which lay the paper.

“I will.” Cotton patted his jacket as though he wasn’t at all sure where he had placed the sheet, and nodded. “Good-night.”

Kendall, hunting his books, reflected that Cotton wasn’t so bad, after all. Why, to-night he had been quite human! Of course, he shouldn’t have taken possession of the room in the absence of the occupants. There was an unwritten law at Yardley that if a fellow was not in, you went no further than the threshold unless you happened to be a particular friend and had permission to make yourself at home. However, Cotton had behaved so amiably that Kendall was ready to forgive the breach of manners. He had almost liked the fellow to-night!
