Football--

Dick Harlow thought that MacKinney, with only one afternoon of scrimmage at the quarterback post under his belt, was a bit uncertain on his blocking and shoved George Helden into the breach at the end of the first quarter. The MacKinney experiment will be continued this week, however, in the hope of finding a way to set the ball moving. . . . Princeton tried a pass play with Rose throwing the ball for the first time this year. Rose started off to his left and was about to throw a left-handed pass to two unguarded mates deep in Harvard territory when Joe Koufman nipped him from the rear and saved the day.
