ABSTRACT

The man who is certain he is right is almost sure to be wrong; and he has the additional misfortune of inevitably remaining so. All theories are fixed upon uncertain data and all of them want alteration and support. Given the efficacy of the other soil-transporting mechanisms it can be concluded that their combined effects would exceed any that result from creep by a considerable margin, so that attempts to measure creep in topsoils in these circumstances is labour in vain. The chapter shows how the orientation of bladed ironstone clasts changed from being parallel to the bedding at the base of the subsoil towards the direction of maximum topographic slope at its top. This slight but undoubted directional change can be compared to the more chaotic arrangement of the same type of clasts in the topsoil, which reflects the impact of bioturbation.
