“How’d you know where he roomed?”

“Easy. Looked up the fellows on the team until I found a couple who roomed in Wallack. Half of them do room there, because it’s a sort of senior dormitory, I guess.”

“Looked ’em up where?” demanded Dick.

“In the school catalogue. There was a copy in the library. I forgot to say that we visited the library amongst other places of interest. I found one football chap lived in 17 Wallack and another in 28, and I knew that one of them must be on the back, and it turned out to be 17, and that was Harold’s dive.”

“Summer’s? But, look here, seems to me Summer’s name is George,” said Stanley. “Where do you get this ‘Harold’ stuff?”

“Had to call him something, and Harold sounded sort of convincing, sort of like what a Phillipsburg fellow would be called. Get me?”

“Oh! Well, say, suppose Summer didn’t go back to his room until after supper or something? Have you seen Sandy since?”

“Oh, yes, he’s aboard. I saw him in the station. He didn’t see me, though. I think he wants to. That’s one reason I wasn’t keen for going after the chocolate. Something tells me that Sandy has misconstrued my innocent efforts to save his money for him!”

“Gee, but I’ll bet he’s mad enough to bite a nail!” chuckled Stanley. “Of all the crazy stunts, Rusty, that’s the craziest! How did you know Summer wouldn’t have a room-mate and that the room-mate wouldn’t be in when you got there?”

“I didn’t. I couldn’t find that out without going through the whole catalogue, and there wasn’t time for that. If there’d been anyone in when I knocked I’d have just asked for a fictitious name and backed out again. Anyway, I don’t see what Sandy has to be peeved about. He saw the game without paying a cent!”
