ALKALI LANDS 



219 



The soil is seen to have been extremely rich in alkali salts, 

 which reached 1-381 per cent, in the first 3 inches at the end of 

 the summer, or -513 per cent, in the first foot; but the salts 

 in this case were of a comparatively harmless character, very 

 little sodium carbonate being present.
