Fourteen Harvard undergraduates and six Radcliffe girls left yesterday afternoon for a summer of teaching and working in Africa on Phillips Brooks House's Project Tanganyika. The group, separate from the Peace Corps, is the largest American delegation going to one country in Africa for the summer.

The 26 students bid goodbye to parents and friends yesterday at Logan International Airport and departed for New York, Brussels, and eventually Tanganyika on Africa's east coast. Most of them will teach English, although two will work on famine crews.

The departure climaxed a busy orientation week at PBH during which the group crammed on Swahili and African culture and listened to African visitors.

After President Kennedy supported the Peace Corps idea during his campaign, the students started Project Tanganyika on their own and raised the necessary $33,000 from parents and corporations.

The leader of the group, Peter C. Goldmark '62, went ahead three days ago to prepare the project in Tanganyika. Accompanying the group was the Rev. Ronald Maitland, of the Christ Church in Cambridge.
