50,000 Hear Curran Sum Up by Radio
Wireless Carries His Call Upon Voters to End Sinister Reign of Hearst by Beating Hylan To-day
Would Restore Self-Rule
City Deserves Better Fate Than Four Years More of Plundering, His Last Plea
Henry H. Curran, coalition candidate for Mayor, delivered his final message to the voters of the city last night over the wireless-telephone. He spoke into the apparatus at the De Forrest radio station at Highbridge, which flashed his words to the 15,000 stations in and about New York. It was estimated by the wireless managers that more than 50,000 persons heard his message.
A wireless telephone connection was hooked up at coalition headquarters at the Murray Hill Hotel, where Mr. Curran's words were written down and distributed to the newspapers. The coalition candidate made a strong last appeal to the voters to defeat Hearstism, Hylanism and Murphyism and to establish a forward looking city government.
