Hal went to his bed exhausted but couldn’t sleep, he was so worried. Hans fell asleep promptly or thought he did. As a matter of fact he was only half dozing with the problem going through his mind. He was so intent on it that he was thinking of it unconsciously and as he thought he was asleep he thought he had a dream of getting on a train to go some place. Oh yes, he was trying to find Hal, he was getting on the back end of the train and as he walked into the car he saw Hal sitting on the last seat of the car, blue hat, mixed gray suit and all, and he saw himself going up to speak to him and greet him in true college-boy style, hitting his friend on the back as hard as his right hand would permit him, and just as his hand was about to fall on Hal’s shoulders he looked and, “By George!” said Hans, jumping out of bed and running over to Hal’s room like mad, shouting, “I’ve got him. The fellow with the blue glasses! Blue hat, gray suit, just like yours on the same train.” Then he told Hal about the fellow on the train whom he had almost forgotten. How he thought he was Hal and was just about to hand him one when he had noticed the blue glasses and then found it wasn’t Hal. He wound up by saying, “Find the other fellow with the blue hat, the mixed gray suit and the blue glasses and we’ve got the medal thief.” [Illustration: “Find that man with the blue glasses!”] CHAPTER XI THE STUDENT DETECTIVES The first thing they did in the morning was to hunt up Hughie. They routed him out before breakfast. When they saw him they told him the whole story from beginning to end. They told him about Hal’s suspension for a week, and fixed it up with him for Hal to carry his cane and limp when anybody was around. Then Hans got excused from practice for a few days, also without any particular reason except the one to Hughie that he wanted to put in his spare time on a little detective work. After breakfast they went to Mr. Williams’ house. It was still before hours, and after a little delay, Mr. Williams came downstairs. Hans told him about seeing the fellow with the blue glasses on the train, also that he had a hat and suit on that looked a good deal like Hal’s. Mr. Williams was deeply interested and gave them both permission to absent themselves from class for a few days, asking them to report to him each evening. He said, too, he would tell the detective whom they would employ that day so they could help run down the clew. For three days they hunted the town over to find a merchant who might have sold a blue cloth hat like Hal’s, but without result. The same thing happened when they tried to find one who had sold a pair of blue glasses. They didn’t make a bit of progress. The station agent couldn’t recall anyone with a blue hat buying a ticket to Boston that day. He didn’t even remember that Hal had worn that kind of a hat or a gray suit, or even that he had bought a ticket.
