    The symposium on Dispersive Clays, Related Piping, and Erosion in Geotechnical Projects was presented at the Seventy-ninth Annual Meeting of the American Society for Testing and Materials held in Chicago, Ill., 27 June - 2 July 1976. Committee D18 on Soil and Rock for Engineering Purposes sponsored the symposium. J. L. Sherard, consulting engineer, and R. S. Decker, Hoskins-Western-Sonderegger, Inc., presided as symposium co-chairmen and editors of this publication.
