r I ^HE purpose of the present investigation was -I to determine whether the clay and colloid content of soils could be determined by photoelectric measurements of the turbidity of soil suspensions at specified depths after suitable periods of centrifuging. Photoelectric turbidity measurements have been applied previously to the determination of concentrations of suspension, and size-weight distribution of paint pigments, Portland cement, bacteria, soil materials, and various colloidal materials (9, 4, 2)? Since dilute suspensions of soil clays (o.oi to 0.1%) are suitable for photoelectric turbidity measurements (2), it would appear that the concentrations of clay <2^ and
