attributed to the fact that an excessive amount of the latter was used. 

 The analytical data obtained at Geneva bearing on this point is shown 

 in the following table:

ANALYSES OF SOILS. 



In the comparative table of analyses given below, including such 

 stations as sent samples of soil, two methods of examination were 

 employed, namely, the method of the Association of Official Agricul- 

 tural Chemists," and the method of ascertaining the quantity of min- 

 eral matter soluble in N. 200 hydrochloric acid, as proposed by C. C. 

 Moore, of the Bureau of Chemistry. 6 The first method gives practi- 

 cally all of the mineral matter in the soil that may become available in 

 many } r ears. .The second method represents an attempt to determine 

 the quantity of mineral matter (in this case potash and phosphoric acid 

 only) which is available for the immediate uses of a crop. The method 

 has been developed, however, with special reference to the oat plant. 

 A glance at the analytical data obtained shows a wide difference in the 

 character of these soils, both in respect of the total amount of plant 

 food eventually available and the amount immediately available.
