When the varsity swimmers leave Princeton tonight, they will leave behind them wreckage that was once a proud team.

With victories over Cornell, Rutgers, Army, and Dartmouth the Tigers stand undefeated in the Eastern Intercollegiate Swimming League. They have a top freestyle distance man and a national champion diver. They will probably lose by approximately 31 to 64.

If Crimson coach Bill Brooks were to unleash all the chaos that he holds in check, the gap might even be wider. But he probably won't.

In the past Brooks has shown himself a practitioner of what might be termed the lalssez-faire school. Limiting the supply when the demand is small, he always produces the goods in the face of serious threats like Navy.

Tonight the demand will not be too great, at least not for a team that has beaten Navy. Tiger strength lies only in three events.

Despite Jeff Lewy's marked improvement, he will find himself hard pressed to out-dive Tiger Tim Walker, current national junior diving champion. In the freestyle distance events, the favorite will be Princeton captain George Brakeley, who holds university marks in both the 220 and 440.

The rest will all be Crimson. In the sprints, Brooks has a powerhouse on tap: Olympian Bruce Hunter and Bill Zentgraf (who both out-distanced Navy flash Ashley Norfleet last week), Bob Kaufmann, Alan Engleberg, etc.

In the butterfly or the individual medley, Brooks can call on Kaufmann, Jim Coffman (who won the finest race of his career in the fly last week), George Pringle, and others.

In short, Bill Brooks has a corner on most of the swimming talent in the East. Princeton coach Bob Clotworthy must be an unhappy man this morning.
