Page 4 University Daily Kansan Monday, March 8, 1967 LatinAmericaAttends Educational Seminar For the next five weeks, twenty-two Latin American educators will be at KU attending the Sixth Seminar on Higher Education in the Americas. The annual seminar, of which KU Dean George Waggoner is director, is at KU for the third straight year. It started March 1 and will end April 10. It is sponsored by the State Department, the University and the Board of Associated Research Councils. ITS OBJECTIVE IS MORE investigative than decision-making according to Assistant Dean Thomas Gale, KU's Peace Corps director in Costa Rica. The seminar, comprising writers, university professors and administrators, is considering improvements in national and university developments; university reforms; how it can aid national development, and what obligations it has, Assistant Dean Gale said. The delegates, representing 16 Latin American countries, are meeting every morning in the Pine Room of the Kansas Union. The conference is divided into four sections with varying titles, Anna Herzfeld, translator and assistant to the director, said. The subjects are: "The University and its Development"; "The University Organization in the United States and Latin America"; "The University Profession and National Development"; "The Role of the University as a Research Center" IT IS HOPED THAT THROUGH this seminar and the sharing of ideas involved, communications can be advanced between all countries of the Americas and the solution of common educational, economic social, and cultural problems can be facilitated. Miss Herzfeld said. It is hoped that the participants will write two papers on the seminar from the points of view of their own experiences and professions, she continued. The two subjects around which these papers will revolve are: 'The Responsibility of the University in National and Regional Development" and "The University's Educational Reform for the Professions". The papers will be published and distributed throughout the Americas to desiring educational and research centers for action resources. Exiles Bombard Soviet Embassy WASHINGTON —(UPI)— Four Cuban exiles, protesting the presence of Russian troops in their homeland, Sunday hurled soft drink bottles filled with a black liquid at the front of the Soviet Embassy. Each threw a bottle at the grey stucco building in downtown Washington. Three of the bottles left smears on the first-floor area of the four-story embassy. The fourth landed on shutters covering a second-floor window. Police arrested the four on charges of interfering with foreign diplomatic property and destroying private property. Lawrence Trees Fight Blight More than 4,500 trees will become guinea pigs this spring in the Lawrence area. Entomologists at KU and in Lawrence are waiting for summer to see whether their experimentation with bidrin, a chemical used for eliminating Dutch elm disease, was successful. Dutch elm disease is a severe disease of elm trees caused by a fungus carried by bark beetles. It begins with a wilting of the younger branches in the upper part of the tree and later the lower branches become affected. In mid-summer, all but a few of the leaves at the branch tips, turn yellow, curl and drop off. "The Dutch elm disease became prevalent in Lawrence in 1959 but it wasn't until the spring of 1963 that bidrin was used to eliminate the disease here," Vernan Cooper, entomologist concerned with Lawrence trees, said. "That year we injected 54 trees with the chemical. We lost one. The next spring we did the same thing to 4,700 and lost several. I think the disease had already started in those." Bidrin is a preventive of Dutch elm disease and can't work if the tree is already affected. This chemical eliminates the bark beetle. Bidrin, when injected, protects the tree for the entire year. Last year the entire elm protection operation cost Lawrence about $12,-000 for 4,700 trees.
