The following soils were selected : 



The Trinity clay, the Sharkey clay, the Iberia clay, the Wabash 

 Iclay, the Waverly clay, the Miller clay, the Dunkirk clay, the Cam- 

 eron clay, and the Houston clay. The last is the only one selected 

 that is not an alluvial soil. 



Table I shows the combined percentages of silt and clay and of 

 clay alone in both soil and subsoil in each of these clays. In Table 

 II are given the clay and silt contents of 11 samples of the Sacra- 

 mento clay for comparison. Table I states briefly the agricultural 

 use that is made of each soil and its agricultural possibilities in the 

 various areas in which it has been mapped.
