An essential aspect of investigations of settlement of foundations and of stability of structures and earthworks is the experimental determination of the stress-strain-time responses and strength properties of clay and organic soils. These should not only be representative of the conditions that control and have significant direct applications to the solutions of the practical problems involved but also should be reliable and fully adequate for the purposes of these investigations. It should be recognized that clay and organic soils exhibit significant creep in their performances at ordinary working stress levels. The prerequisite to the attainment of these very practical engineering objectives are: first, to test and treat real soils under the influences of essentially real and representative conditions that control, and; second, to work consistently toward high conceptions of adequacy and standards of excellence in soil investigations.
