The word "crust of the earth' for the upper mineral strata of our planet indicates a life-process in which a hardening and a solidification have arisen in the course of time. As in many other cases, the wisdom of language brings to expression a fact which no longer lives in human consciousness.
In connection with water, air and heat, forces are active in the mineral earth which are related with the processes of life. When primary rock crumbles away under the influence of the elements, it yields an excellent and fruitful soil for the growth of plants. Plants could never draw from it the forces they need for their development unless the soil contained formative forces. They could never grow upon a completely lifeless soil.
