EYBORATORY determinations show that heavytextured soil in good physical condition is relatively high in water-stable aggregation. In studies of soil tilth, the question constantly arises concerning what constitutes high aggregation under optimum conditions in a given soil. Since aggregation appears to vary with texture as well as with conditions subject to some measure of control, such as alkali and effects of tillage, it becomes desirable to have a criterion that may be applied in the laboratory for judging whether aggregation of a particular sample is relatively high or low. Baver, using 77 different soils, found a high correlation between aggregation and the amount of 5-micron
