Extract

1. It is shown that the plasticity of a soil, as measured by the flow-plasticity test, is correlated with soil temperature and moisture. Although the measurement is made on a paste of the soil made smooth by working the mass of soil with water, and then forcing it through a fine sieve, the flow plasticity of the paste still depends on the climatic history of the soil from which it is prepared.

2. The soil has, in general, a higher plasticity in cold and dry weather and a lower plasticity in warm and wet weather. These results seem to confirm the conclusions of Vinokurof about seasonal fluctuations in the quantity of highly dispersed particles.
