An examination of tlie above table reveals that the water content of 

 the soil was not markedly rednced between the fourth and fifteenth inch 

 layers. Moreover the upward translocation was confined to the region 

 below the fourth inch layer of soil. The high concentration of the 

 surface layer was due to the translocation of the soluble material 

 originally present or formed in the soil as evidenced by the condition 

 found in the untreated containers. 



Another series was run wherein the salted laj^er was placed 24 inches 

 from the surface. Inasmuch as the film movement did not take place 

 more than fifteen inches from the surface the movement of the added 

 salt which was confined to the section below this^ was due to diffusion 

 as the data set forth in table 4 show.

Similar studies were conducted with muck. The translocation of the 

 salts that were placed twelve inches from the surface was found to be 

 as presented in table 5. In this case the salt had moved upward to 

 the sixth inch layer, but had not passed to the bottom of the tube.

The results obtained from medium sana are of interest. 



The sand contained four per cent moisture wdien placed in the cylinders, 

 preliminary studies having revealed that aowiiward translocation of the 

 water resulted with higher water contents. The salted layers were 

 placed six and twelve inches from the surface respectively. The experi-
