FIG. 1. Showing method of studying capillary movement of salts in different 

 soil types, and the effect of mulches upon the distribution of salts in soils. 



Mean distribution of salts in three soil types after a capillary 

 movement during 15 to 23 clays. 



This table contains only the data obtained from that cylinder 

 in each series which was subjected to the longest capillary 

 movement. Each of the other cylinders was also examined in 

 such a succession as to show the capillary movements of salts 

 which had taken place at the end of intervals of different dura- 

 tion.
