Both first and last place in the Eastern Swimming League will be at stake Saturday when Cornell hosts the undefeated Crimson in a 2 p. m, meet.

Before the first event begins, Harvard will be tied for first place with the winner of today's Penn-Princeton encounter. A win over Cornell would make the Crimson record 4-0, slightly better than the 3-0 records which Princeton. Yale, and Dartmouth will probably share after Saturday's schedule.

Cornell, meanwhile, has managed to stay out of last place only through the ineptitude of Columbia. Both teams have yet to win a league meet, but the Lious have lost four to Cornell's three. The Big Red's only triumph thus far was a 72-32 rout of Fordham.

Though Cornell has had an undistinguished season, it has three performers who have done extremely well and who are likely to inject a bit of competition into what otherwise could be a boring meet.

George Boizelle has posted times among the top ten nationally this year in both the 200-yard butterfly and the individual medley. He is also a proven competitor in freestyle events and the backstroke.

Cornell coach Peter Carhart will be hoping to make better use of his star this year than he did last winter against Harvard Boizelle took first in the backstroke, but Carhart made the mistake of putting him against Toby Gerhart in the 200-free, and Boizelle lost by nine seconds. He also swam a leg for the medley relay team.

One good race should be the butterfly, where Boizelle will probably face the Crimson's John Munk. Munk's best time of the season- 2: 00. 1- is three-tenths of a second slower than Boizelle's top time. Another close race may be the individual medley if Harvard coach Bill Brooks uses Steve Krause, and if Boizelle is entered.

The rest of Cornell's strength is in the dives, Senior Tim Millhiser, sophomore Ken Light, and junior Matt Leone are all good With the home advantage. they are slightly favored over Harvard's excellent trio of Dave Silver. Tom Wallace, and Dick Eisenberg.

If the Crimson is successful on the two boards, the afternoon will be intolerably miserable for the Big Red because the Cornell swimmers will for the most part have to be happy with third-place finishes.
