''Continued observation and experiments will without doubt enlarge tbe limits 

 of tolerance as given in tbe tables. . . . The results represent the maximum amount 

 per acre of each salt found in any soil wbere that particular plant was found grow- 

 ing, and without reference to the other salts in the same soil. Thus for the cowpea 

 the maximum of carbonate of soda was found in one soil, that of the sulphate in 

 another, and the chlorid in still some other soil." 



Analyses are given of a number of samples of alkali soils sent to the 

 station for examination from different parts of the State.
