The residual clay from the limestone presents greater differences, due to the almost entire disappear- ance of calcium carbonate. The diagrams for the two clays resemble each other fairly closely in spite of their widely differing sources. Because weathering causes the persistence and accumulation of sihca, aluminium, and iron, and a loss of the basic materials, all soils as they weather tend to approach a similar composition. Yet, owing to a difference in the adjustment of the forces at work and in the time element, no two soils will ever be exactly alike. Soils will differ, then, from the original rock and from one another according to the intensity.
