ANALYSES OF WHEAT. 



VIF. WINTER WHEAT FROM THE SAME COUNTY. 

 Furnished by Mr. Beach. Grown upon a gravelly soil. 



Analysis of the ash. 



Silica and coal 12-134 



Earthy phosphates 37-072 



Alkaline phosphates ..... 21-313 



Potash , 22-496 



Soda 7-348 



Chlorine ....... trace. 



Sulphuric acid trace. 



Magnesia and lime ..... 0-031 



Note. I was desirous of repealing all those analyses in which so much foreign niattert 

 as coal and sand, existed. Experience subsequently enabled me to avoid this objectionable 

 state of the ash ; still, the results are correct for all the elements except silica. In regard 

 to this, I have lieen satisfied that it varies from 1-50 to 5 per centum ; and it is probable, 

 in those varieties grown upon soils of Lewis county, that they reach the maximum per- 

 centage. The grain has a thick cuticle, and is rather dark ; and it is in these kinds that 

 the silica is in the largest proportions.
