Grapevine

By PAUL GRAY/

THE FOG IN PRAGUE FALLS MAINLY IN THE BOG. When they think of Peace Corps volunteers, Americans are likely to imagine idealistic young folk, sporting sunburns and khaki shorts, digging wells in Tanzania. That image will need some revision when volunteers start arriving in the world's newest developing area -- Eastern Europe. Agreements have been signed for 60-member teams to begin working in Hungary and Poland this summer, and a similar program is being negotiated for Czechoslovakia. In the initial phase, all the volunteers -- whose average age has increased from 24 to 31 since the program began -- will teach English. But the corps is prepared eventually to offer instruction in small-business management, agriculture and, says one official, "just about anything that will do some good."
