"It is necessary for Congress to delegate to administrative agencies and bureaus the more detailed tasks with which it is encumbered, while retaining ultimate control itself over policies," said Frank S. Hopkins, Nieman Fellow, and reporter for the Baltimore Evening Sun, in a radio broadcast over station WEEL, last night.

The broadcast was sponsored by the Harvard Guardian, which will be host to delegates to its Conference on the American Public Service which begins today. Other participants in the discussion were W. Rupert MacLaurin, Professor of Industrial Relations at M. I. T., and Laurence I. Radway '40, undergraduate chairman of the conference.

Hopkins admitted that the public is quick to suspect tyranny in an administrative service that becomes too powerful. "The word 'bureaucracy' makes many people think of a swarm of undisciplined office-holders descending on our liberties," he said.

"Intelligent publicity regarding administrative functions is an effective safeguard against the misuse of bureaucratic powers," he added.

Both Hopkins and MacLaurin are among the 32 authorities invited to meet with 30 undergraduate delegates in the second current social science congress the Guardian has called. Although the conference will not begin officially until tomorrow morning, a preliminary meeting of undergraduate delegates will be held in Winthrop House Senior Common Room tonight.
