THE popularity of rowing goes beyond the Boat Race, beyond the local excitements of Oxford and Cam-bridge. It extends to Henley, Mar-low, and many other Thames-side regattas, to thousands of water carnivals on English rivers. But the tradition of rowing springs from the Public Schools and the Universities, and of late years has been the subject of long and hitter controversy. The new tradition of the ' Jesus style,' and its many modifications, supported by new influences from the Dominions, the Continent, and America, has challenged persistently the old tradition associated with Eton and Trinity. The rival followers fight an interminable battle on and off the water. Mr. G. 0. Nickalls, an old Oxford blue, explains the points of the controversy and their influence on rowing everywhere today.
