The previously published data, to which reference has already been 

 made, and which it is proposed to discuss in connection with the 

 analyses presented in the foregoing table, comprise the analyses of 

 twenty-four samples, representing twelve soil types distributed in 

 four soil provinces. 



The results of these analyses, for major constituents only, are pre- 

 sented in Table 2.
