A long-standing friendly rivalry between two government professors will break out in public at 7:30 p.m. tonight at a Dunster House forum. Arthur A. Maass, assistant professor of Government and Charles R. Cherington '35, associate professor of Government will lock horns in a debate on the public power issue. Carl Kaysen, assistant professor of Economics, will be the moderator.

Maass, who teaches Government 157, Conservation of Natural Resources, and Cherington, who presides over Government 155, Regulation of Industry, have been taking pot shots at each others' views from their lecture platforms all year. Maass is expected to present the case for extensive government development of power facilities, and Cherington will argue for a plan of mixed government and private enterprise in the power field.

Wednesday, the forum committee will present Alex Inkeles, senior research fellow in the Russian Research Center, speaking on the results of his recent interviews with escapees from Iron Curtain countries.
