London, August 9. I saw yesterday at the National Physical Laboratory. Teddington, wax models of designs for new ships being tested in tanks by experts who believe that by this method a racing yacht might bel built that would compete success- fully in the America's Cup races.

Major B Heckstall-Smith, "The Daily Telegraph" Yachting Correspondent, stated in yester- day's issue that American ex- perts considered that the pro- digious speed of Ranger, the de- fender, was due to the hull form evolved from tank tests upon models. He also said that Eng- lish yacht designers have scoffed as tank tests.

An expert at Teddington, who is also a naval architect, informed me that the laboratory had never been asked to make tests of models of

American Warned For Batting

New York, August 9. George Daly, the Blackfriars light-weight, who came to the United States with Tommy Farr, made a good start to his own campaign by out- pointing Mike Piskin, of New Jer sey, last night. The decision was booed for five minutes by some of the crowd, who considered that Piskin should have had the verdict. Piskin was aggressive through- out a fast bout, though Daly land- ed hard and often. Piskin scored with lefts and rights in in fighting. In the third round he was warned for butting.

MAKO AND HENKEL

Donald Badge, the new Wimble- don champion, and Baron Gottfried von Cramm of Germany, who put up such a great fight against him in the Davis Cup, will probably have several further clashes in Australia, if present plans materi- alise.

Budge and Meko and von Cramm and Henkel are representing the United States and Germany, respec- tively, in the Australian champion- ships at Adelaide from January 22 to 29, the final of which is expect ed to be between Endge and von Cramm

In addition to this, however, there is a strong move in favour of trian- gular international matches be tween Australia, United States, and Germany.
