In the 1928 Olympiad Weismuller again won the too metres, in 'sec. faster time than in 1924, but the American successes were not so sweeping as at Paris, Argentina, Germany, Holland, Japan and Sweden winning events. In 1932 at Los Angeles Japan pressed forward more threateningly. In the water events the U.S.A. se cured 170 points to 99 for Japan and 21 for Australia, but Japa nese swimmers captured first place with new world's records in most of the men's swimming events. The United States and Japan were again outstanding in 1936 at Berlin.
Channel Swimming.—Much interest has centred in the many attempts to swim across the English channel ; the first recorded attempt was made on Aug. 24, 1872, by J. B. Johnson, who started from Dover, but remained in the water only 65 minutes. It was on Aug. 12, 1875, that Capt. Matthew Webb made his first attempt. He started from Dover and remained in the water 6hr. 49min., when the weather became too rough for him to continue. It is estimated that he was about 131 miles across when he had to give up. On Aug. 24 and 25, 1875, he swam across the Eng lish channel, diving from the Admiralty pier, Dover, and touch ing Calais sands, after swimming for 2 'hr. 45min., and at the time this accomplishment created a great sensation in England. Since then twenty-one other successful attempts have been made and they are as follows :—Sept. 6, 191', T. W. Burgess, 22hr. 35min.; Aug. 6, 1923, H. Sullivan, 27hr. 25min., Aug. 12, 1923, S. Tira boschi, i6hr. 33min.; Sept. 9, 1923, C. Toth, i6hr. 54min.; Aug.
6, 1926, Miss G. Ederle, I4hr. 34min., Aug. 28, 1926, Mrs. Corson, shr. 28min.; Aug. 3o, 1926, H. Vierkotter, i2hr. 4omin.; Sept. 1o, 1926, G. Michel, 'hr. smin.; Sept. 17, 1926, N. L. Derham, 13hr. 56min.; Aug. 5, 1927, E. H. Temme, 14hr. 29min., Oct.
7, 1927, Miss M. Gleitze, I shr. 15min.; Oct. 13, 1927, Mrs. Ivy Gill, I shr. 9min.; Aug. 19, 1928, Miss Ivy Hawke, 19hr.
Aug. 24, 1928, Miss Hilda Sharp, 14hr. 58min.; Sept. 1, 1928, I. Helmy, 23hr. 4omin. ; Sept. I o, 193o, Miss Peggy Duncan, i6hr. Ismin.; Aug. 29, 1933, Miss Sunny Lowry, 15hr. 45min.; Aug. 18, 1934, E. H. Temme, 15hr. 54min., Aug. 18, 1934, Emma Faber, i4hr. 4omin.; Aug. 22, 1935. H. Taylor, 4hr. 48min.; Aug. 4, 1937, T. Blower, 13hr. 29min. Messrs. Webb, Burgess, Sullivan and Temme (second swim) swam from England to France and all the others from France to England.
The great leap forward in speed swimming, however, followed the introduction of the crawl stroke, first used in standardized racing by Richard Cavill of Australia. The earliest knowledge of the crawl obtained by Americans was gleaned from hazy news paper descriptions of Cavill's stroke. In attempting to imitate the action they unwittingly developed a faster leg drive, executing four scissoring kicks per stroke, instead of the two performed by Cavill. The new leg drive was combined by Americans with the double over-arm action of the trudgeon, and the resulting stroke christened four-beat crawl, to distinguish it from the two-beat Australian variety.
