Fig. 7.— Diagram showing the average total salt content of the soil at six depths in 1913 on plats which 
had received treatment according to the first, second, and third methods, respectively, and of adjacent 
virgin soil. 
salts contained in the surface 4 feet of soil will be considered first, 
Table XIII gives the average salt content to a depth of 4 feet in 1913, 
and figure 7 shows graphically the same results. These samples were 
taken on May 2, June 5, July 16, September 3, and October 23, 4-foot 
borings being made on each date.
