Atomic energy, discussions of its significance in peace and war, and a demonstration of the basic principles of chain reacting piles will feature Boston's "Salute To The Atomic Age," at which Harlow Shapley, director of the University Observatory, will act as chairman in the Hotel Bradford Ballroom Monday night at 8 o'clock.

Sharing the floor with Shapley and other scientists, Senator Brien McMahen, chairman of the Senate Atomic Energy Committee, will speak on "Legislative Control of the Atomic Bomb." The entire program, which includes a playlet on push button atomic warfare, will emphasize civilian use and control of atomic energy.
