"To quote Casey Stengel. 'The boys done good,' "coach Jack Barnaby said of his squash team's victory over Penn on Saturday. "But I keep telling the team that now they've passed the big hurdle they have to be careful not to stumble on the smaller ones."

The varsity squash squad, heading toward the Ivy and intercollegiate team title, will face a hurdle at 2 p.m. this afternoon when Princeton arrives at Hemenway Gym.

All season long the collegiate squash news has been dominated by Penn and Harvard, for no other team in the nation has the material to challenge either titan. On Saturday, the match of the year was played at Hemenway and the Crimson claimed all the marbles with a narrow 5-4 victory over the Quakers.

Coach Jack Barnaby now has the problem of motivating his team for another all-out effort against Princeton. The Tigers have dropped matches to Penn. Army, and Navy, all Harvard victims, but still the Princeton match offers several challenges at particular positions.

Princeton is very strong at the top positions. Sandy McAdoo, ranked sixth intercollegiately at the beginning of the year, is now playing at number two behind captain John MacColl. Although Princeton lost to Navy. 3-0, at six positions, MacColl and McAdoo completely outclassed their opponents in three games. While Harvard's Larry Terrell should withstand MacColl's threat, senior John Ince will certainly be hard pressed by McAdoo at number two.

The only other experienced player on the Tiger squad is senior Beb Ross. A starter at number eight last season. Ross will face Ed Atwood, hero of the Penn match, at the fourth slot.

At the beginning of the year. Princeton coach Bill Summers said of his squad. "We're as green as grass from number four down. None of these guys had ever played a varsity match before."

Two weeks ago. Penn destroyed Princeton, 9-0, for the Tigers' most humiliating defeat in history. But Harvard's chances of repeating the feat are slim. First, Princeton will be remembering the embarrassment of the Penn loss. But more significantly. Princeton's strength at two through four directly challenges Harvard's Achilles heel. Gonzales and Atwood will have to repeat their upset performances of Saturday to maintain any chances of a lopsided win.
