Harvard's varsity indoor track team goes after its sixth straight Big Three championship today, facing the thinclads of Princeton and Yale at Princeton's Jadwin Gymnasium. The Crimson is 4-1 this year, having placed second in last week's Greater Boston Championships.

The stiffest competition for the Harvard troops will come from the Tigers, who have clawed their way to a perfect 8-0 record this season. The Princeton thinclads are looking to become the first undefeated track squad in the school's history.

Highlighting the Princeton floor show is the spectacular two-mile relay team of Chuck Norelli, Jeff Weicksel, Craig Masback and Chuck Hedrick. The group has competed at the Melrose Games and the Philadelphia Track Classic, with a top time of 7:40.3.

Balanced Forces

Sophomore pole vaulter Dan Willges leads the balanced Tiger forces in the field events, showing a 15 ft. 6 in, effort as his lifetime best. The second leading point-getter on the Princeton team, Willges will be facing Harvard co-captain Blayne Heckel in the vault today.

The high jump will see Harvard's sensational Mel Embree in action once again. The junior set individual, meet and University records last week with a 7 ft. 2 1/4 in. jump in the GBCs.
