           Rankine notes that adhesion is useful in helping ground stand up in temporary work but plays no part in his design, which is consistent with Coulomb s law. Adhesive or cemented strength may arise as small creep strains occur and as bonds develop in undisturbed sedimentary soils, but any such bonds are, in Rankine s view, destroyed by weathering, and in Coulomb s view destroyed by remoulding. These two founders of soil mechanics are in agreement.
