§ 34. 1. The permeability and capillarity constants of soil have been defined.
2. The movements of air and water through three types of soil have been measured and shewn to conform to equations connecting the rate of motion with the above constants.
3. It is suggested that the measurement of S, Pα, Pω and K is of more importance than, and should replace, the determination of the sizes of the soil particles as in the usual “mechanical analysis” of soils.
In conclusion, we have to acknowledge our indebtedness to Professors T. R. Lyle and R. J. A. Barnard for valuable advice and suggestions and to the Victorian Government for financial assistance towards the expenses of this research.
