William C. Becker '51 and Melvin L. Zurier '50 topped a field of six contestants yesterday to take the 51st annual Coolidge Debate Prizes. Each man will receive $150. This is the second time that Zurier has won the prize.

The Coolidge Prizes are awarded to the two best debaters in the trial debates for the Harvard-Yale-Princeton debates. In yesterday's contest, Becker, Bruce S. Lane '52, and Richard W. Hulbert '51 debated the negative of the topic: "Resolved: That the United States should recognize Communist China" against Zurier, Walter C. Carrington '52, and Lloyd J. Walker '50.

Becker, Lane, and Hulbert will debate the same side of the same question at Yale tomorrow, while Carrington, Walker, and Zurier will repeat their arguments against a Princeton team here.

Drawn from the income on a gift by T. Jefferson Coolidge, Class of 1850, the prizes were first established in 1899. Preliminary trials for the H-Y-P debates determine the actual composition of the teams which will face Yale and Princeton.
