In a communication to the GeologicalMagazine, published in July, 1936, I gave a brief description of the rocks that build the Kedong scarp. I propose now to amplify that description. It is not always realized that the geological structure of the Rift Valley has been deduced almost wholly from physiographic evidence, and that proof of the alleged displacements must depend upon exact petrographic study of the rocks involved in the structures.
