Tonight's talk on 'Surfing on Australian Beaches' will be Mr. W.C. Lyle's second broadcast, for listeners will remember that he inaugurated the autumn series of these talks with his.'Sports in other Countries' on October 7. Mr. Lyle, an Australian, has been round the world four times; he has lectured all over America, has lived in forty countries, and was once coach to the King of Siam. His vivid personality finds its right medium in the microphone.
