N 1; leaves at base dried up: 5 mo. 

 old, 4.5 ft. high. 



3 783 " 15 in- Weak, sickly cane, leaves yellow; 3

 incrustation. 



4 1025 " 15 in. Cane dying; leaves yelow; 3 to 4 mo. 



old, 15 in. high; surface incrustation. 



5 1410 " 18 in. Better cane, leaves green; 5 mo old 



2.5 to 3 feet high. 

 In table XIII are given the results of the analyses of the two samples, 

 representing the first and scond foot respectively, of each location. 

 The average figures for the entire depth of two feet are also given, as in 

 this loose soil the roots of the cane will penetrate beyond the first foot. The 

 first column of table XIII indicates bicarbonates calculated as bicarbonie 

 acid ion, (HC03) 2, as has been done before; column 2 gives the chlorine 

 (C12), the third the sulfuric acid ion (S04), the fourth the sum total of 

 acid radicles, and the fifth the sum of bicarbonie acid and chlorine. The 

 reason for this arrangement will soon be apparent.
