Penn and Harvard, early season favorites to battle for the Ivy League crown on Saturday, watched their title hopes die last weekend as Dartmouth. Princeton, and Yale remained undefeated and top contenders in the wide-open Ivy race.

Penn, demolished by injuries in its opening games, could never generate an offensive threat in Princeton's Palmer Stadium and easily succumbed to the Tigers. 42-0

The Quakers, now 1-2 in the League standings, gained only 48 yards in total offense. Through the air, Penn receivers caught just one pass while the Princeton secondary picked off four errant tosses.

While Penn's offense was stalling, the Tigers were in full gear. Princeton ground out 246 yards rushing and added another 242 yards through the air. Ellis Moore caught one touchdown pass and ran over the Penn defensive line for two more.

Star of the game was the Tigers' quarterback Scott MacBean, who passed for 140 yards and added another 32 yards rushing. For this individual performance, MacBean was selected as the Ivy League's Back of the Week.

In New Haven, the nation's fifth-ranked defense against rushing met the country's number-one runner, and the Bulldogs succeeded in halting Cornell's Ed Marinaro for a 17-0 Yale victory over the Big Red.

Marinaro received a painful hip injury early in the game and retired from the match in the third quarter with only 30 yards to his credit. The sophomore superstar had entered the game with an average of 211 yards a game on the ground.

Without Marinaro, Cornell's offensive attack was about as impotent as Penn's. The rest of the Big Red's rushers accounted for negative eight yards, while quarterbacks Rick Furbush and Bill Arthur completed only four passes for another 38 yards.

The victory was the Bulldogs' seventeenth Ivy win in a row over three seasons. Eli quarterback Joe Massey marched the team 74 yards after the kick-off, depending mainly on the running of half-back Don Martin and fullback Bill Primps, and the outcome of the game was decided.

Against outside competition, Brown and Columbia both faded in the fourth quarter. Rutgers relied on reserve quarterback Mike Yancheff to overcome a 14-point Columbia lead and clinch a 21-14 victory in the closing 38 seconds.

This weekend Dartmouth and Yale battle in the Yale Bowl for the Ivy League lead while Brown faces Princeton and Columbia trayels to Cornell.
