William P. Arnold '31 of the University golf team with a par-breaking gross 71 lead the field of 167 starters in the three-day open tournament which ended Saturday at the Wellesley Country Club. A five handicap gave him a low net score of 66.

Arnold set his field-leading mark on Friday, playing with E. B. Murphy '31, a teammate at Harvard. With a smart 33 on the inward nine, he would have smashed the course record had he been able to negotiate the fourth hole in par, but he took a bad six. In the next 14 holes, he had nine pars, four birdies, and a single over-par mark, a five on the last.
