The remoteness of the relation between the alkalis or m the sur¬ 
face portions of the land and the salts removed by the drainage-waters 
is made evident by the analyses of the alkalis from the land through 
which this drain, or its laterals, run. 
This sample of alkali was taken a few' feet from a lateral open 
drain emptying into the main ditch a few hundred feet south of this 
point.
