Despite setting two more new University records, the Harvard swimming team failed to match its first-day performance at the NCAA Swimming and Diving Championships at Knoxville, Tenn., as the Crimson could manage just two more points yesterday for a two day total of seven.

Hess Yntema became the lone Crimson scorer of the day as he took an 11th in the 100-yd. butterfly for Harvard's points.

Facing increasingly stiff competition from the other participating schools, Harvard faded slightly from 16th place Thursday to 20th in the standings at the conclusion of yesterday evening's finals. Indiana, despite some inconsistent performances. Continues to hold a comfortable lead over the University of Southern California for first place. The Hoosiers' two-day total now stands at 233, with USC second with 194, and host Tennessee third with 167.

Harvard had a blanced mixture of good swims, and not so good swims in the afternoon qualifying heats. Dave Brumwell swam a fine race in the heats of the 400-yd. Individual Medley, but failed to qualify. His time of 4:13.04 was two seconds better than his time at the Easterns, and it established a new University standard.

Steve Furniss of Southern Cal completed a record-breaking IM double as he established another new American, and NCAA record with a very fast winning time of 3:55.160. Bob Atkinson of Penn, who turned in a similar IM double at the Easterns, took ninth in 4:05.

The Crimson had no one entered in the next event, the 200-yd. free as head coach Don Gambril decided to concentrate on the 800-yd. free relay later in the program. Jim McKonica of Southern Cal won the championship final in 1:39.625 after qualifying sixth and barely reaching the finals. Indiana, with a 2-3 performance from John Kinsella and Fred Tyler, strengthened its grip on first.

In the trails of the 100-yd. butterfly Tim Neville and Hess Yntema turned in good times, with the latter's 50.91 clocking qualifying him tenth in the event. Neville swam a better time, 51.59, than he did at the Easterns in the heats, but failed to make the consolations.

Yntema dropped down to 11th in the consolation finals last night, but he lowered his own Harvard record to 50.57 in the process. His time was just one hundredth of a second slower than that of rival Bob Meade of Cornell, who beat Yntema in the event at the Easterns.

The Big Red, on the strength of Larry More's second in the 1-meter dive and Meade's tenth, remain ahead of the Crimson in the battle for the best finish among the Eastern schools. Princeton, with an 11th from Charlie Campbell in the 100-yd. back, picked up its intial two points of the meet.

In the finals of the 100-yd, fly, hometown hero John Trembley, who must have felt a draft after shaving his head for the contest, turned in a very fast 48.688 performance to beat Indian's Gary Hall for first. His time was .7 off the American and NCAA record held by Mark Spitz set at last year's nationals at west Point.

The elusive 100-yd. backstroke record the only one still held by a pre-Don Gambril swimmer-faile to fall for fresh man Tom Wolf in the afternoon trails as he swam slightly off his best time with a 54.96 clocking. As it turned out, Wolfs 54.21 opening leg on the Crimson's 400-yd. medley relay which took twelfth on Thursday night was the closest he came to breaking Dan Kobick's record of 54.20.

In the finals of the event. Mike Stamm of Indiana paced an incredible 1-4-5-11 performance by the Hoosiers' turning in a phenomenal new American and NCAA record time of 50.910. It was the first time in history a backstroker has broken the 51 second barrier.

Co-captain elect Phil Jonkheer, the victim of a freak accident Thursday night which required five stiches in his hand, swam a courageous race in the heats of the 100-yd. breastroke but his time of 1:02.15 was well off the Harvard mark he set at the Easterns.

In what had promised to be one of the best duals of the meet, John Hencken of Southern Cal, an Olympic gold medal winner, easily beat rivals Brian Job of Stanford and Tom Bruce of UCLA in the finals of the 100-yd. breast. His winning time of 57.111 was just .3 off Job's American and NCAA record. Job, whose failure to make the U.S. Olympic squad in Chicago this summer was a big surprise, faded to fifth in the finals and just about put a finish to his swimming career.

Harvard had hoped to do well enough in the heats of the 800-yd.. freestyle relay to pick up at least a couple of points, but the eighthranked contingent failed to match its University record time set at the Easterns, finishing in 6:59.85, and missed the consolations.

The Crimson's splits were just not quite good enough, but the times were good regardless. Captain Fred Mitchell led off with another consistent 1:44.43 leg, but second man Mike Cook failed to equal his superlative 1:43 clocking from the Easterns with a good 1:44.92. Rich Baughman swam slightly off his best career time with a 1:46.68 performance, but Hess yntema turned in an excellent anchor leg, with a closing 1:43.82.

Indiana, with four incredible swims, won the evening final going away in new American and NCAA record time of 6:36.390, erasing the old mark of 6:38.635 set by Southern California last year. All four Hoosiers broke the 1:40 barrier led by Kinsella's opening 1:39.65, Connolly's second in a time of 1:39.99, Tyler's excellent 1:38.05, and Hall's anchoring 1:38.70 clocking.
