In the above table, the terms used shall be deemed to have the following mannings:
the undisturbed rock mass whose minerals show no sign of decomposition.
a Ane-grained inorganic soil possessing sufficient cohesion when dry to form hard lumps which cannot readily be pulverised by the Angers.
(e) Stif clay, clay which can be removed by spading a fresh sample of which can be moulded by a substantial pressure of the fingers.
(b) Soft clap, clay which when freshly sampled, can be moulded under relatively alight pressure of the fingers.
Red Earth. the residual soil formed by decomposition of the rock mass,
