In recent years many persons have recognized the need for some means of bringing together all students of clay materials, whether they be mineralogists, ceramists, chemists, physicists, agronomists, engineers, or geologists, who are interested in and actually studying clay materials. The American Institute of Mining and Metallurgical Engineers held a symposium on Problems of Clay and Laterite Genesis during their meetings in St. Louis in 1951 which brought together for the first time a large number of student of clay materials from many different fields. Following the symposium a National Clay Minerals Committee was established which was charged with the task of finding some means whereby all students of clay materials might meet to discuss common problems and to obtain some coordination of their efforts. After much deliberation the National Clay Committee decided the best way to approach its objective would be to set up an Interdivisional Committee on Clay Minerals within the National Academy of Sciences National Research Council to be administered by the Division of Earth Sciences of the Council. The Academy-Research Council welcomed this idea, and in 1953 such a committee was established with representatives from several other Divisions of the Council and from substantially all of the disciplines that are concerned with clay researches. One way in which the Clay Minerals Committee is attempting to attain its objectives is by joining in the sponsorship of Annual National Clay Conferences. The first such conference was held at the University of California in Berkeley, California, in 1952, the second one is reported on herein, and a third one is planned for Houston, Texas, on October, 1954.
