These i-esults do not indicate any danger from brack in the 

 soil, not even in Nos. 17 atid 18. taken from lands which were 

 said to show indications of brack. It was, therefore, not deemed 

 recessary to examine more closely into the nature of the soluble 

 salts. With regard to Nos. 17 and 18, it is, of course, possible 

 that the brack salts may be found at lower levels, e.g.. three or 

 four feet below the surface. 



Plant Food Constituents. 



With regard to the presence of moisture, of organic and 

 volatile matter (lost in ignition of the .soil), and of plant food 

 m the soil, the determinations detailed in the following table 

 were carried out : —
