Andy tried to get Dunk interested in football, and did to a certain extent. Dunk went out to the practice, and Andy tried to get him to go into training. "No, it's too late," was the answer. "Next year, maybe. But I like to see you fellows rub your noses in the dirt. Go to it, Andy!" Link Bardon seemed to find his employment at Yale congenial. Andy met him several times and had some little talk with him. The young farmer said he hoped to get permanent employment at the college, his present position being only for a limited time. Andy had received letters from some of his former chums at Milton. Among them were missives from Ben Snow and Chet Anderson. Chet wrote from Harvard, where he had gone, that he would see Andy at the Yale-Harvard game, while from Ben, who had gone to Princeton, came a similar message, making an appointment for a good old-fashioned talk at the annual clash of the Bulldog and Tiger. "I'll be glad to see them again," said Andy. It was about two weeks after the arrival of Link Bardon at Yale that some little disturbance was occasioned throughout the college, when an announcement was made at chapel one morning. It was from the Dean, and stated that a number of articles had been reported as missing from the rooms of various students. "You are requested to keep your doors locked when you are out of your rooms," the announcement concluded. There was a buzz of excitement as the students filed out. "What does it mean?" "Who lost anything?" "I have," said one. "My new sapphire cuff buttons were swiped." "I lost a ring," added another. "And a diamond scarf pin I left on my dresser walked off--or someone walked off with it," spoke a third. There were several other mysterious losses mentioned. "How did it happen?" asked Andy of a fellow student who had said a few dollars had been taken from his dresser. "Hanged if I know," was the answer. "I left the money in my room, and when I came back it was gone." "Was the room locked?" "It sure was." "Did any of the monitors or janitors see anyone go in?" "Not that I know of; but of course it could happen. There are a lot of new men working around here, anyhow." Andy thought of Link, and hoped that the farmer lad would not be suspected on account of being a stranger. But as the days went on the number of mysterious thefts grew. Every dormitory in the quadrangle had been visited, but the buildings outside the hollow square seemed immune. CHAPTER XXI A GRIDIRON BATTLE Harvard was about to meet Yale in the annual football game between the freshman teams. The streets were filled with pretty girls, and more pretty girls, with "sporty" chaps in mackinaws, in raglans--with all sorts of hats atop of their heads, and some without hats at all. There had been the last secret final practice on Yale Field the day before. That night the Harvard team and its followers had arrived, putting up at Hotel Taft.
