According to this analysis, the soil, to the depth of one foot, contained 



Organic matter 366856-875 lbs. 



Lime 16539-187- 



Magnesia 1701-562 



Potash - - - - - - - 11182-250 



Soda 33010-312 



Chloride of sodium .... 816-750 



Sulphuric acid 272-250 



Soluble silica 9869-062 



The phosphates were appreciable, but too small in amount to be weighed. 



It may be repeated in this place, that the soils of the true Wheat district are not so rich 

 in phosphates as the soils of the Hudson river and Eastern districts. 



The following exhibits the soil of the east acre as it is, or after a crop of corn and oats 

 (I believe) have been removed, but which had been highly manured as stated in the fore- 

 going remarks. 



One hundred grains, saturated with moisture, gave 



Soil as it is.

100 grs. of dry soil gave
