Sophomore Dave Hawkins broke his own 150-yard medley record, as the varsity swimmers swamped M.I.T., 71 to 13, in the Tech pool.

Earlier, the freshmen beat the M.I.T. freshmen, 48 to 27.

In another demonstration of its depth, the varsity shuffled its lineup and proceeded to win every event and take second in all but the dive and the 300-yard backstroke.

Hawkins bettered his record of 1:36.6, which he set Feb. 21, 1953, by 1.8 seconds, as he beat teammate Mary Sandler in 1:34.8. In the 300-yard medley relay, the Crimson team of Don Mulvey, Ralph Zani, and Bill Travis beat M.I.T. by 1 1/4 laps in 3:05.3.

The most lopsided win of the evening was scored by Captain Charlie Egan in the 440-yard freestyle, when he edged teammate Rapperport by five yards and M.I.T. by 3 1/2 laps in 5:03.7. Ted Whatley barely beat Jim Jorgensen in the 220-yard freestyle in 2:17.9.

Jack Millard was the only Crimson double winner, as he captured the other two freestyle events, the 50 in :24.3, beating out Jack Dinsmoor, and the 100 in :55.8, edging Duke Geer.

Zani out swam Dick Stenson to take the 200-yard breaststroke in 2:29.8, and in another Crimson victory the 400-yard freestyle relay team of Whatley, Gus Johnson, Jim Buffington and Jorgensen lapped the Engineers, winning in 3:43.2.

In the backstroke, Mulvey placed first and Eric Ueland third; Mulvey's time was 2:26.7. In the diving, Marshall Walter took first with a score of 81.58.

The Yardlings took first in seven of their nine events, losing only the diving and the 150-yard medley relay.

Freestyle wins were posted by Frank Weller in the 50, Jon Lind in the 100, and Chouteau Dyer in the 200. Bob Jaffe took the breaststroke, Paul Santemire the backstroke, and Pete Macky the individual medley. The other Yardling win was in the 200-yard freestyle relay.

Dave Bryson could do no better than third in the dive, as the M.I.T. freshmen took first and second. The Yardlings also lost the 150-yard medley relay.
