In the discussion of this paper, it is pointed out that if it is a question of shear failure in a slip layer, the discussion of the resistance should, among other things, include the transfer of normal stresses from the grains to the clay matrix and to the water (or in the opposite direction), which is connected primiairly to a tendency towards volume change of the soil skeleton, and also include dilatancy itself. That the particle orientation is most important is indicated by the great influence on strength of remoulding. Therefore, even in the case of constant volume, the pore water may temporarily carry a part of the load. In laboratory tests, one must imitate the slip layer, the loading and the shearing procedure. The drawing up of a strength formula by accumulating test results must be made with utmost care. Starting from the principles of the theory of stability, on the one hand, and of strength on the other, one should discuss the behaviour of soil exposed to a relevant shearing deformation and find out the mutual developments of energy from the impelling and resisting forces; a study of their variation with the shearing deformation.
