The question naturally arises: why are the silica horns buried in the earth over summer and not exposed directly above the earth to the forces active in warmth, light and air? My own consideration is that the point is not to concentrate the forces in the cow horn in the manner in which they work directly above the earth, but rather to work with those same forces insofar as they are absorbed by the lime beneath the earth and thereby work indirectly — mediated through the clay — on plant growth through the root.
