Report in two sections.

1. Interviews on the hustings with Kenyatta and Ngala do not reveal the tribal animosity which reporter considers is the crucial factor in dividing the African vote between KANU and KADU. KANU representing the Kikuyus wants strong central government, a policy opposed by KADU which is supported by smaller tribes who want strong regional assemblies, fearing Kikuyu domination. Asians and Europeans, of minor political significance in these elections for the Senate, House of Representatives and six regional assemblies, also fear discrimination despite African pledges to build a multiracial society after independence. Report fears that election will perpetuate tribal rivalry and prevent Kenya becoming a united nation. 2. Frenchman who accidentally discovered the Lascaux Caves in 1940 recalls his story over film of the wall paintings. Appearance of green spots on the paintings has baffled scientists who cannot tell whether they are caused by light conditions or the breathing of tourists. Caves have been closed indefinitely to prevent further deterioration and enable instruments to check atmospheric conditions. Closure will destroy nearby Montignac's tourist industry.
