A wide range of testing and research projects on soils is covered in the papers included in this publication. These projects vary from field tests of piles in sand to properties of soil-cement mixtures. A total of twelve papers were presented in three sessions during the Second Pacific Area National Meeting held in Los Angeles, Calif., during the week of September 17, 1956. Eleven of these papers, together with discussions, are included in this publication with one paper on Soil Density and Soil Moisture Determination by Radiation Methods by R. K. Bernhard, Rutgers University, not published in this group. An added feature in this publication is the address presented by Prof. K. B. Woods at the Soils Industry Luncheon. This presentation reviews the important techniques used for site selection and for explorations.
