THIS PAPER IS BASED ON A LABORATORY INVESTIGATION OF 36 SOIL SAMPLES PREPARED FROM 9 VARIOUS CLAY MINERALS AND THEIR MODIFICATIONS AS A RESULT OF BREAKDOWN OF CHEMICAL CONSTITUENTS AND CHANGES IN PHYSICO-CHEMICAL PROPERTIES BY HEAT TREATMENT AT THREE DIFFERENT TEMPERATURES. THE MULTIPLE CORRELATION DRAWN BETWEEN THE INDEPENDENT VARIABLES OF PLASTICITY INDEX, PARTICLE-SIZE LESS THAN 2 MU, CATION EXCHANGE CAPACITY, AND SODIUM AND THE DEPENDENT VARIABLE, FREE-SWELLING, GIVES A COEFFICIENT OF 0.974. IF SURFACE AREA IS USED INSTEAD OF CLAY FRACTIONS LESS THAN 2 MU, THE COEFFICIENT OF MULTIPLE CORRELATION IS 0.976. SIMPLE CORRELATIONS AMONG CLAY FRACTIONS LESS THAN 2 MU, SURFACE AREA, AND COMPOSITE INDEX ARE ALSO ANALYZED. /AUTHOR/
