Hal Ulen's swimmers, undefeated in three starts this season, should get a chance to give a good show at Columbia tomorrow afternoon when they face practically the same hapless team that they whipped last year, 62 to 13.

Ulen personally expects no trouble, and will throw in almost the identical lineup that he used Wednesday in boating Brown, 45 to 30.

Number Four?

"This should be number four," he confidently stated last night. The Lions dropped a close decision to Navy last Saturday, and the Middles, as an old saying goes, have never been known as notoriously good swimmers. Saturday is Alumni day down on Morning side Heights, and Ulen is out to show the graduates what Navy did, "only twice as bad."

Ted Norris will swim his specialty, the quarter-mile, during the day's festivities. He looks certain to win. In the dive, Gordon Weir will back Tom Drohan, who will be making his last appearance for Harvard. For the 400-yard freestyle relay, a quartet will be placed together out of Shop Brown, Mort Hull, Bill MacVicar, Bob Burke, Bob Lang, and Art Sicular.

Ready to Go

Larry Ward and Chuck Hoelzer are scheduled for the breaststroke, and Tom Woods and John Steinhardt will fill the backstroke slots.

Jerry German and Bob Burke will race the 220-yard freestyle, and Bob Burke and Shop Brown should fight it out in the 100-yard.

Proposed trio for the 300-yard medley relay is Woods, Hoelzer, and MacVicar.

Ulen Inc. will spend tonight at the New York Harvard Club.
