-In the final round of trials and eliminations today in the Olympic water sports carnival, Johnny Weissmuller, Chicago speedster and defending champion in the 100-meter free-style, set a new Olympic record in the semi-finals of that event. Weissmuller, ace of the American swimming forces, flashed over his favorite distance with huge, space-devouring strokes in 583/5 seconds. István Bárány, Hungarian, who finished second, gave the American speed king a fight through every inch of the first fifty meters, making the turn with him on even terms. Weissmuller forged ahead with a tremendous burst of speed in the final thirty meters, flailing the water with mighty strokes.

With Weissmuller in the final tomorrow will be George Kojac, the New York schoolboy, and Walter Laufer of Chicago. Victory in the men’s 100-meter dash already is conceded Weissmuller, with Laufer and Kojac likely to complete the first three names on the board. Alberto Zorilla, the Argentinian, who won the 400- meter championship in spectacular style yesterday; Katsuo Takaishi, the Japanese, and Bárány of Hungary, other finalists, appear only as dangerous contenders to Laufer and Kojac. They hold little threat to Weissmuller’s supremacy.

Arne Borg, Swedish champion, who came to grief yesterday, losing to Zorilla and Charlton of Australia in the 400-meter finals, was scratched from the second heat of the 100-meters in which he was scheduled to start. The official reason given was that he was stale. Swimming pool devotees and others said that Borg was none too eager to try conclusions with Weissmuller and risk a second defeat. In Swedish circles there has been much comment of Weissmuller’s being scratched in the 400 meters, and hints were broadly expressed that the American feared Borg. Weissmuller was being quoted as having promised to give “Mr. Borg a little medicine in the 100 meters.”

Weissmuller, who shattered the oneminute barrier at the Olympic Games at Paris in 1924 in 59 seconds even, swam with such apparent carefreeness in his heat that some spectators interpreted his attitude as contemptuous. After permitting Spence, who was swimming in the adjacent lane, to remain head to head with him for seventy-five meters, the American put on a little spurt at the finish and won by about a yard.

Johnny Weissmuller won the gold medal in the 100-meter freestyle the following day, equaling his Olympic record as he edged Istvan Bárány for the fourth of five career gold medals. Weissmuller won his fifth later in the Games in the 4×200-meter freestyle. While training for the 1932 Los Angeles Games, he was spotted by a Hollywood producer and cast in the starring role of Tarzan, the ape man. Weissmuller would make 12 Tarzan movies.
