82 THE DATE PALM. 



The following amounts of alkali were found: 



TABLE 15. Per cent of alkali in soil of young date plantation, station No. 2, Fougala, 



Algeria. 1 



1 Mr. Seidell's original analyses of the samples from this station are as follows: 



The results of three years' irrigation with pure artesian water is very striking. The 

 surface crust has disappeared entirely and the amount of alkali has greatly decreased 

 at all depths. 



Station No. 3 at Fougala was situated in the space between large date palms, which 

 were in a most thriving condition as a result of eleven years' irrigation. Garden 

 vegetables and cereals had been grown on the land for a number of years. The 

 hardpan layer was reached at a depth of only 26 inches.
