nel, and the seed shells was subjected to separate analyses, 

 obtained are found in the following table: 



Composition and distribution of the ash. 



The data 



It will be noticed from the above table that potash is the principal 

 mineral ingredient of the ash of the sunflower from whatever part of 

 the plant it is derived, with the possible exception of the leaves, where 

 the content of potash is comparatively low. Lime is an important 

 constituent of the ash in all cases, but especially of the leaves. Mag- 

 nesia is found in about the same abundance as lime, being larger in 

 quantity than the lime in the ash from some parts of the plants and 

 lower in others. 



The principal acid in the pure ash is phosphoric, although the con- 

 tent of this acid is quite low in the stalks and naturally high in the 

 seeds. If the kernels and hulls of the seeds be studied separately it is 

 found that the percentage of phosphoric acid in the ash of the kernels 

 is 50.84, while in the hulls of the kernels it is only 6.83. 



It is evident from the above data, including the composition of the 

 sunflower itself, that it is a plant which makes considerable drain upon 

 the three principal mineral plant foods, viz, nitrogen, phosphoric 

 acid, and potash. 



COMMERCIAL MANUFACTURE OF SUNFLOWER OIL IN THE UNITED 



STATES. 



Many inquiries have been received asking for information in regard 

 to the manufacture of sunflower oil on a commercial scale in the 

 United States, and a diligent search has been made to discover any 

 factories engaged in this enterprise. The addresses of several milling 

 companies were secured, which it was thought might have informa- 

 tion in regard to the matter, and letters were addressed to them for
