$(6)$ A fine grained soil is being tested to determine if it is a silt or clay. Dry clumps of this

soil are tested by applying pressure to determine the dry crushing strength. If a clump

cannot be broken with finger pressure alone but can be broken by applying pressure

between the thumb and a hard surface, how would the dry strength be reported:

medium, high, very high? If this same soil when wet can be rolled into a thread with

ease, would the soil be classified as an inorganic silt, clay of low plasticity, or clay of high

plasticity?
